| 摘 要： | 镇江市新区第二污水厂进水主要是新区化工园区的混合化工废水,针对生化系统经常遭受异常进水或毒性物质冲击的情况,提出了以耗氧速率(OUR)及COD去除率和硝化速率评价污水可生物降解性的方法,以提高活性污泥系统的处理效率和运行管理水平。研究结果表明,六类化工企业废水的毒性大小顺序为农药类﹥电子类﹥染料类﹥造纸类﹥橡胶类﹥酒精类。

| Abstract: | 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. |
