The influent of No.2 Wastewater Treatment Plant in Zhenjiang New District is mainly mixed chemical wastewater.To solve problems such as shocks caused by influent abnormalities and toxic matters,this paper proposed to evaluate the biodegradation capacity of the wastewater by promoting oxygen uptake rate（OUR） of mud,COD removal rates and nitrification rates so as to upgrade the operation management level of activated sludge system.This study indicates that the toxicity sequence of the six chemical industrial effluents was pesticide effluent〉electron effluent〉dyestuff effluent〉papermaking effluent〉rubber effluent〉ethyl alcohol effluent.
