Flocculant is a set of efficient bleaching bleaching, flocculation, removal of COD equal to a new type of organic quaternary amine polymer flocculant, formula (C4H8N5X) n. Its bleaching effect is significant (95% removal) of COD, SS, BOD removal rate is also higher. Applications efficient flocculant is mainly used for bleaching bleaching high chroma dye wastewater treatment for reactive, acid and disperse dyes and other soluble dye wastewater treatment. Can also be used for the treatment of textile bleaching, chemicals, coke, paper, printing, dyeing, leather, urban sewage, industrial sewage stations and other wastewater. Can replace bleach water, activated carbon, polyacrylamide and other agents. Paper can also be used as a reinforcing agent, sizing agent. Performance 1. Efficient and easy to dissolve in water discoloration flocculant, so that the water can form polynuclear complex colloidal particles, suspended particulate matter coming together grow to form a large volume, high density, fast settling floc. 2. In water treatment, bleaching efficient flocculant PH broad scope of the raw water (PH7.5 ~ 10), the most suitable for slightly alkaline. 3. Efficient bleaching flocculant no corrosive effect on the plumbing, sewage chroma, SS, COD, BOD removal efficiency, the treated wastewater can meet the national emission standards, and provide a final water reuse plant. 4. Efficient bleaching flocculant no suspended solids or sediment, will not clog dosing equipment and piping, can be directly used for wastewater treatment dosing liquid, no secondary pollution. 5. Efficient bleaching flocculant produce large floc density, soluble in water, less sludge. 6. Efficient bleaching flocculant of anionic, cationic, nonionic, can be targeted for a variety of wastewater treatment. Flocculant flocculation method works is the choice of inorganic flocculants (such as aluminum sulfate) and organic ammonium anionic polyacrylamide flocculant (PAM) formulated into aqueous solution wastewater, will produce electric double layer compression, so the wastewater suspended particle loses its stability, mutual cohesion colloidal matter so increases the formation of floc floc particles. Brought up to a volume flocs after departing from the aqueous phase by gravity sedimentation, a lot of wastewater to remove suspended solids to achieve the treatment effect. To improve the separation efficiency, can be timely, appropriate coagulant added. Treated wastewater in color, chromium, suspended solids, etc. Basically, to meet emission standards, can be used as artificial or efflux back waterflooding water. 2 Application of a municipal sewage flocculants used isolated from urban sewage has flocculation, degradation of flora and efficient mixing of treated sewage, effluent COD and BOD allows removal of 100% 1. A Class 2 waste materials building materials processing wastewater effluent containing high suspended solids also more difficult to deal with, such as ceramics factory wastewater, including two wastewater and wastewater embryo glaze, the former mainly contains more clay particles, which in addition to with clay particles, there are quite a number of glaze. When adding NOC-1 5 min after water turbidity embryo reduced from the original 1.4 to 0.043; glaze water turbidity decreased from 17.2 to 0.35; turbidity removal rates were 96.6% and 97.9%, obtained almost transparent supernatant. Tile factory waste water treatment flocculant Rhodococcus resulting supernatant treated almost transparent. 3 Other applications due flocculant is safe, non-toxic properties, is gradually being adopted in the food wastewater treatment, and achieve satisfactory results. In addition, microbial flocculants can be widely used in urban sewage, hospital sewage, petrochemical waste, paper waste, pharmaceutical waste water treatment and other aspects of the process. Conclusion In summary, from low molecular weight to the polymer, from inorganic to organic and microbial, by a single type of flocculant to the complex is the development trend. Pursuit of efficiency, cost, environmental protection is the goal of flocculant developed, targeted to develop non-toxic or low toxic flocculant to drinking water and other human activities related to water treatment residues of biological toxicity and no longer cause 2 pollution is an important direction for future research and development of flocculants. Second, strengthen the quantitative study of flocculation, reduce production costs is imperative to develop new flocculant. In the dual drive theory and practice, the security, non-toxic, efficient flocculant great trend to replace traditional flocculants, inorganic and organic polymer composite flocculants also due to a combination of inorganic and organic advantages obtained at home and abroad a wide range of conduct, has become a hot research flocculants. Situation 3 Conclusion Throughout flocculants can be seen, flocculants variety, from low molecular weight to the polymer, from a single type to the complex, the general trend is to the cheap and practical, non-toxic and efficient direction. Inorganic flocculants cheap, but on human health and the environment would be adversely affected; organic polymer flocculant though with less and less dross production, strong flocculation ability, easily separated floc, good oil and suspended solids in addition to the effect of However, residual monomers such polymers have a "three letter" effect (caused by Kawasaki, carcinogenic, mutagenic), so its application is limited in scope; bioflocculant because there is no secondary pollution, easy to use application prospects attractive. Bioflocculant may replace or partially replace traditional inorganic polymer and synthetic organic polymer flocculant in the future. The development and application of microbial flocculants in the ascendant, its characteristics and advantages for the development of water treatment technology shows a broad prospect. 4 flocculant coagulant effect of water purification process plus what is the role of the main inorganic coagulant flocculant, organic polymer flocculant and microbial flocculants are mainly dealing with all kinds of sewage, specifically - organic polymer flocculants in the treatment of refinery wastewater, other industrial wastewater, high suspended solids in wastewater and solid-liquid separation cationic flocculants has wide applications. Especially acrylamide series of high molecular weight organic polymer flocculant its strong bridging flocculation ability to demonstrate its superiority in water treatment. A wide range of microbial flocculant, flocculation activity, and the role of the condition is extensive, mostly without ionic strength, pH, and temperature, it can be widely used in sewage and industrial wastewater treatment. Flocculant is added to the water and impurities fast, more thorough separated Bioflocculant role compared with the organic polymer flocculant, flocculation bioflocculant has a wide scope of activity, safe, non-toxic, does not pollute the environment, and other characteristics, and conditions of use thin set, there is a broad spectrum of flocculation activity, and therefore, can be widely used for water supply and sewage treatment. ⑴ high concentration organic wastewater treatment, high concentration organic wastewater mainly contains livestock waste and other food and farm waste, such normal biological treatment of wastewater before adding flocculation pretreatment process. Bioflocculant motive worse than SPA flocculation, by means of the time, if not a large number of different microbial flocculant SPA mixed before the war, the consequences of wrong monosodium glutamate wastewater pretreatment can step back progress, and the total investment of pharmaceutical quality manifest Tim narrow. ⑵ fire wear color printing and dyeing waste scrap its light color of fruit, group total complex, exposed without dye, a variety of materials slurry, to help agents, fibers, because of glue, wax content, organic salts, etc., remain hidden for the state ended Industry One of the difficulties many small wastewater chaos under management. Its easy to point a non-processed high COD, and B / C values ??of the older, the division of the poor; two groups of non-color high and the total complex. The key is to bleaching and dyeing wastewater treatment, in a variety of approaches to flocculation dwarf fruit of their investment outlay, equipment accounts for more days, disposal capacity is small quality, high bleaching is widely adopted. Different kinds of micro poly iron flocculants death compared flocculant flocculation accumulation not only have good performance NAO, and the existence of good bad consequences to wear color, printing and dyeing waste fire in the West without the normal flocculant not have the upper hand, flocculant. ⑶ high degree of organic light suspended wastewater address the high light of the non-organic suspended wastewater aging mention whether a non-wastewater system, the traditional teaching of agronomic normally take flocculation and treatment. No matter flocculants are slightly cooked for kaolinite ocean, mud slurry, fly ash and other water sample processing, the outside pass function in experimental micro flocculation and division ceramics factory waste water treatment, waste water war glaze body waste. ⑷ solved piecemeal effectiveness of activated sludge sludge often results in poor performance and decreased light to mention, when the West participated in the activated sludge micro-dead flocculant, whether the sludge volume index can be very fast landing, preventing sludge flocculation system dispel sludge contraction condition and restore the primary sludge weight back up to nature, the effectiveness of all the progress the disposal system. Interest for one kind of type of flocculant therefore, slightly cooked flocculant has good use of bad vision, not generally used in high-light of the inorganic waste solutions, waste fire wear colored dye, activated sludge treatment treasures disposal West and shows a strong life force. Micro flocculant not dead. PAC solution provided the best use of the following: a first laboratory analysis, if the solid-liquid suspension substances physiognomy negative potential (usually negative), the program can be used PAC + CPAM. 2 to determine the amount of PAC: also need to do a test chamber in the amount of testing to determine the amount and cloud effect curve PAC alone use. A PAC dosage under 3 if the best results when used alone, you can actually use the amount as 1/4--1/3 A value, while the remaining work to be done CPAM. 4 laboratory to determine the proportion of PAC and CPAM added: that the PAC amount of 1/3 case A value CPAM need to determine how much effect the bridge will unite most appropriate PAC linked together. Through the experiment, to determine the proportion of added use of PAC and CPAM. Use and costs 1. Efficient bleaching flocculant available liquid or water to dilute 10% to 50% and then added directly to the water, stir alum after a few minutes, the colored wastewater colored precipitate from water flocculation, sedimentation or flotation with, achieve separation. 2. Wastewater, COD is high, decolorizing flocculant can be efficiently used in conjunction with inorganic flocculants to deal with, but not mixed use, this can reduce processing costs, before adding or after adding inorganic flocculants, should be based on experiments and treatment process may be. This can reduce processing costs, and the proportion of investment in order pharmacy should be determined according to the actual. 3. Efficient bleaching flocculant dosage 0.03 ~ 0.5kg / T wastewater (effluent depending on the concentration), colored wastewater treatment costs can generally be controlled at 0.25 to 1.5 yuan / T. Dyeing wastewater general industrial use (depending on the concentration and species may be) is 0.3/10000 ~ 0.8/10000. Packaging and storage efficient bleaching flocculant non-flammable items, non-toxic, harmless to human body. Should be stored at room temperature, not prolonged sun exposure in the hot sun. Storage period of a year and a half. Efficient bleaching liquid flocculant 50kg plastic barrel, solid 25kg plastic bag. Note decolorizing flocculant efficient non-dangerous goods, splashing in the hands, body water rinse.
