摘要
对浙江省某大型化工园区以染料废水为主的一家污水处理厂进行了二期扩建设计。根据现场中试结果,选定一级物化/生化/二级物化工艺作为该厂二期扩建废水处理工艺,介绍了各单元处理构筑物的设计参数。工程竣工后,对COD及BOD5的去除率均可达到80%以上,悬浮物(SS)去除率能达到62%以上。
The design of second-phase extension project of a WWTP in Zhejiang Province is described. The main source of raw wastewater in this WWTP is dye wastewater from a large-scale chemical industry park. According to the results obtained in a pilot-scale experiment, the combined process of first-stage physicochemical treatment, biochemical treatment and second-stage physicochemical treatment is chosen for the second-phase extension project of the WWTP. The detailed design parameters of treatment structures are presented. The removal rates of COD, BOD5 and SS can reach more than 80% , 80% and 62% respectively after the completion.
