低能耗水解酸化/生物滤池污水处理工艺的设计及运行

Design and Operation of Hydrolysis Acidification/Biofilter Process with Low Energy Consumption for Wastewater Treatment

浙江慈溪杭州湾新区污水处理厂前三期建设规模为4×104m3/d,采用水解酸化/生物滤池工艺。该工艺处理效果较好,平均出水水质达到了《污水综合排放标准》(GB8978—1996)的一级标准。处理成本约为0.15元/m3。对各单元的工艺设计参数进行了详细介绍,并总结了设计、运行管理经验。

The capacity of sewage treatment plant in Zhejiang Cixi Economic Development Zone is 40 000 ma/d and the main process is hydrolysis acidification/biofiher. The treatment effect is excellent, and the effluent quality can reach the first criteria specified in Integrated Wastewater Discharge Standard （ GB 8978 - 1996）. The treatment cost is 0.15 Yuan/m3. The design parameters of different treatment u- nits are introduced, and the experiences in design, operation and management are summarized.
