| Abstract: | The pH of wastewater should be alkalized first and the dichlorvos is to be extracted from the highly concentrated trichlorfon industrial wastewater with demulsifier.The results show that after the above treatment,the average COD removal rate is 56.1%,average total phosphorus removal rate 22.2%.After electrolysis,the average COD removal rate reaches 64.2% and after coagulation,the average total phosphorus is 7 600 mg/L and total phosphorus removal rate 57.6%.Its BOD/COD is increased to 0.38,and the biodegrad... |
