摘　　要：某污水厂位于园区产业基地,对园区内不同类型的企业污水进行综合处理,具有进水水质种类多,特征污染物复杂,水质波动大的特点。因此,依据水中特征污染物的来源和种类,设计了生产废水与生产污水分类分质处理的工艺流程,通过运行数据和全流程水质监测,评估工艺设计的适配性。结果表明,对不同的来水水质,按照其水质特征进行分类处理,工艺运行稳定,出水水质满足设计要求。同时,针对生产污水超滤膜系统产水量降低问题,研究膜元件污染物成分以及对污染形式进行分析,其中有机物污染占比72.6%,无机成分以铁与铝污染为主,并依据检测数据与分析结果采取相应措施,化学清洗后膜性能恢复。该项目的成功设计运行可以为园区废水处理工艺的设计提供参考。A certain sewage treatment plant is located in the industrial base of the park,which comprehensively treats different types of enterprise sewage in the park.It has the characteristics of multiple types of incoming water quality,complex characteristic pollutants,and large fluctuations in water quality.Therefore,based on the sources and types of characteristic pollutants in water,a process flow for classifying and treating production wastewater and production sewage was designed.The adaptability of the process design was evaluated through operational data and full process water quality monitoring.The results indicate that for different incoming water qualities,classified treatment based on their water quality characteristics ensures stable process operation and meets the design requirements for effluent quality.At the same time,in response to the problem of reduced water production in the ultrafiltration membrane system for production wastewater,the composition of membrane element pollutants and the analysis of pollution forms were studied.Among them,organic pollution accounted for 72.6%,and inorganic components were mainly polluted by iron and aluminum.Corresponding measures were taken based on the detection data and analysis results,and the membrane performance was restored after chemical cleaning.The successful design and operation of this project can provide reference for the design of wastewater treatment processes in the park.
