- 摘要:
- 在充分调查上游排污企业及现状污水处理厂运行情况的基础上,采用“物化预处理+生化处理+非均相催化氧化耦合多效澄清”组合工艺对重庆某工业园区综合污水进行处理,实现出水COD<80 mg/L,平均去除率≥80%,出水TP稳定低于0.34 mg/L,平均为(0.05±0.05) mg/L,满足重庆市《化工园区主要水污染物排放标准》(DB 50/457—2012)。
- Abstract:
- This study presents the design and operation of a wastewater treatment process for an industrial park in Chongqing. Based on a comprehensive investigation of upstream industrial wastewater sources and existing treatment plants,the process integrates physicochemical pretreatment,biochemical treatment, and heterogeneous catalytic oxidation coupled with multi-effect clarification. The combined process achieves effluent COD levels below 80 mg/L,with an average removal rate exceeding 80%. The effluent TP concentration remains stable at less than 0.34 mg/L, averaging (0.05±0.05) mg/L, meeting the Provincial Discharge Standard of Main Water Pollutants for Chemical Industry Park (DB 50/457-2012) in Chongqing.
