Treatment system for organophosphorus pesticide production wastewater

The utility model relates to a treatment system for organophosphorus pesticide production wastewater. The treatment system comprises a water inlet pipeline, a grid, an adjusting pond, a primary settling pond, an alkaline hydrolysis settling pond, an anaerobic tank, a biogas channel, a facultative tank, an aerobic pond, a horizontal sedimentation tank, a water outlet pipeline, a sludge concentration pond, a belt filter press and a sludge outward transport channel. For the organophosphorus pesticide production wastewater treated by the system provided by the utility model, the water quality of effluent treated is good, pollution parameters such as COD (chemical oxygen demand), BOD (biological oxygen demand), alkali and the like meet the standard of drainage, the environmental pollution problem generated by the organophosphorus pesticide is solved, and the problem for treating the organophosphorus pesticide production wastewater is solved, so that the system is a huge leap in development of existing pesticide industry and is suitable for common promotion and application.
