污水厂不停水应急达标改造工程设计及实施

Design and Construction of Emergency Plan for Compliance of New Effluent Criteria under Normal Operation

针对山西省某污水处理厂现状出水达标率低、处理能力不足等问题,分析认为,影响出水达标的因素除水量波动大之外,进水COD、BOD_(5)、SS、NH_(3)-N、TN和TP等主要污染物浓度远超设计水质是关键因素。为此,在不停水、不扩建用地等情况下进行了不停水应急达标工艺设计,并分析了改造后的实际处理效果,对类似污水处理厂的提标改造具有实际参考价值。

This paper investigates the causes of outlet incompliance of a wastewater treatment plant in Shanxi Province.Besides the large fluctuation of treated wastewater quantity,the inlet pollutants,such as COD,BOD_(5),SS,NH_(3)-N,TN,TP etc.are much higher than what it designed,which results in its incompliance.Therefore,the emergency process design without water outage and expansion of land is carried out,and the actual treatment effect after transformation is analyzed,which has practical reference value for upgradibng and transformation of similar sewage treatment plants.
