Abstract:

The wastewater containing phosphor in pesticide parathionproduction can be dischargecl by biochemical treatment aftermultiple dilution, and the wastewater with alkality in methami-dophos production after methylalchol recovery, which containshighly concentrated organo-phosphorus.COD and sodium chlo-ride, has not been treated before, and polluted the environment.In this article, we give the treatment technique of the wastewa-ter, and has bean applied in the production. The ratio of CODremovement reaches 80%, and of organo-phosphorus reaches85%. We get good effect.
