The main pollution of slaughterhouse wastewater is the high content of organic matter, the wastewater is reddish brown, there is a strong odor and the pollution concentration changes, in the treatment of uncertainty and process requirements are relatively high.
Large domestic slaughtering and processing enterprises adopt equipment and technology, can slaughter and process a variety of poultry and livestock at the same time. This leads to the high concentration of sewage discharged by such enterprises, and the change of water quality and quantity. To solve this problem, we suggest the use of hydrolytic acidification – biological adsorption regeneration – contact oxidation process. This water treatment method adopts the AB two-stage combination process. The load of A stage is high, and the addition of polymeric aluminum chloride and polyacrylamide flocculants with strong adsorption capacity makes the flocculants have good settling performance. The flocculants are compact, large in volume, fast settling speed, and strong in impact load resistance.
Slaughterhouse to choose the appropriate polyacrylamide water treatment agents, according to the acid and alkaline PH value of the water selected, generally before the selection of agents to retrieve the wastewater, after the test test to determine the accurate type of polyacrylamide. Then carry on the computer test to select the appropriate drug, improve the treatment effect.
Polyacrylamide (PAM) is a linear polymer, chemical formula is (C3H5NO) N. It is a hard glassy solid at room temperature. The products are liquid glue, latex and white powder particles, translucent beads and flakes. Good thermal stability. Can be dissolved in water in any proportion, aqueous solution is uniform transparent liquid. After long-term storage, the solution viscosity will decrease due to slow degradation of polymer, especially when the storage conditions are poor.  Polyacrylamide, as lubricant, suspension agent, clay stabilizer, oil displacement agent, water loss reducer and thickener, has been widely used in drilling, acidification, fracturing, water plugging, cementing and secondary oil recovery, tertiary oil recovery. It is a very important oil field chemical.Learn more
Polyferric sulfate is a kind of inorganic polymer coagulant with superior performance. It is a light yellow amorphous powdery solid and easily soluble in water. 10% (mass) aqueous solution is red-brown transparent solution and hygroscopic. Polyferric sulfate is widely used in drinking water, industrial water, all kinds of industrial waste water, municipal sewage, sludge dewatering purification treatment.Learn more
