关于浙江省城镇污水处理厂清洁排放技术改造的工艺选择——基于温岭市某污水处理厂

Process selection for technical improvement of clean discharge of urban sewage treatment plant in Zhejiang Province——Based on a sewage treatment plant in Wenling City

为浙江省城镇污水处理厂清洁排放技术改造的工艺选择提供参考和建议,对温岭市某污水处理厂提标改造的工艺选择和运行数据进行分析。根据实际进水水质和现有构筑物,采用“粗格栅+细格栅及沉砂池+初沉池+改良A/A/O+二沉池+反硝化滤池+混凝反应沉淀池+超滤”工艺,处理效果良好,目前出水水质可稳定达到排放标准,可作为清洁排放提标改造的参考工程。

Provide reference and suggestion for the process selection of clean emission technology transformation of urban sewage treatment plant in Zhejiang Province, and analyze the process selection and operation data of a sewage treatment plant in Wenling City. According to the actual influent water quality and existing structures,“rough grid + fine grid and grit chamber + primary sink + improved A / A / O + secondary sink + denitrification filter + coagulation reaction sedimentation tank + super The filtration process has a good treatment effect. At present, the effluent water quality can be stably reached the discharge standard, and can be used as a reference project for the improvement of clean emission standards.
