Garbage leachate wastewater refers to a kind of high-concentration organic wastewater formed from the moisture contained in the garbage itself in the landfill site, the rain and snow water entering the landfill site and other moisture, after deducting the saturated water capacity of the garbage and the overlying soil layer, and passing through the garbage layer and the overlying soil layer.
Garbage leachate wastewater contains a large amount of harmful organic matter, great pollution, high chroma and heavy odor.
Polyacrylamide produced by Henan Secco plays an important role in the process of landfill leachate treatment. At the same time, the treatment of battery waste liquid which is difficult to be treated or recovered, and the clarifying treatment of syrup in sugar industry can increase the settling speed, improve the soil and improve the soil resistance to wind erosion and water erosion.
The choice of polyacrylamide for landfill leachate treatment mainly depends on the different charge types brought by wastewater quality. Most of the sludge pressing equipment used on site for landfill leachate are centrifuges and spiral stacking machines. Generally, cationic polyacrylamide is used in the field. The specific model still needs to be determined according to the water quality and site mud pressing equipment.
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
