Application of Polyacrylamide in large scale treatment of farm wastewater

TIME:2023-07-21 17:32:42SOURCE:admin

Due to the large amount and concentration of waste water discharged by large-scale farms every day, and the waste water contains a large number of pollutants, such as heavy metals, residual veterinary drugs and a large number of pathogens, if it is discharged into the environment or directly used for agriculture without treatment, it will cause serious pollution to the ecological environment and farmland.

 

The pretreatment process mainly includes grid, grit chamber, water collecting well, solid-liquid separator, sedimentation regulating tank, drying field and other equipment and facilities, as well as the measures of rain and sewage separation and dry manure cleaning in pig house.

 

Polyacrylamide (PAM) can be used in the stage of flocculation and sedimentation. Polyacrylamide is a water-soluble polymer, insoluble in most organic solvents, with good flocculation, which can reduce the friction resistance between liquids.
