Among the current treatment methods for organophosphorus pesticide wastewater, the recommended methods for treating organophosphorus pesticide wastewater are firstly activated carbon adsorption, and secondly activated carbon sludge method. powdered carbon activated After treatment, the wastewater is diluted with a large amount of river water and is discharged into the river. influences.

 

Activated carbon adsorption method is suitable for the waste water of pesticide preparation factories in clear packaging containers, equipment and washing the ground, as well as the waste water from cleaning pesticide packaging containers in farms.

 

Putting powdered activated carbon directly into the biochemical treatment tank can also significantly improve the biochemical treatment effect of dimethoate wastewater. When the dosage is 0.1% of the water inflow, the removal rate can be increased by about 20%.

 

However, the waste water discharged from dimethoate crude oil requires 0.8-1T of activated carbon powder, which is expensive, and the recovery and regeneration methods of carbon powder have not been solved, and there are still problems in industrial application.www.wyactivatedcarbon.com

However, in some special cases, such as when the domestic water is contaminated with organophosphorus pesticides, it is effective and convenient to temporarily use activated carbon for adsorption treatment.
