摘要:
某市政污水处理厂为满足天津市地方标准《城镇污水处理厂污染物排放标准》（DB 12/599—2015）A标准（其中出水TP≤0.3 mg/L，SS≤5 mg/L），在占地紧张、出水水质标准高的情况下，主工艺采用A2/O，深度处理工段采用适量投加PAC、PAM的高效沉淀池，以满足出水TP≤0.3 mg/L，后接Hydro-Clear浅层高效滤池工艺，以满足出水SS≤5 mg/L。该项目自2020年1月正式投运，平均出水SS为2.7 mg/L，稳定满足出水SS≤5 mg/L的设计标准。浅层高效滤池运行期间反洗自用水量<2%，包含电、药耗的直接运行费用为0.004 5元/m3。
Abstract:
To meet the A limitation (TP and SS in the effluent are no more than 0.3 mg/L and 5 mg/L,respectively) of Tianjin local standard in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (DB 12/599-2015), the main process of A2/O and the advanced treatment process of high-efficiency sedimentation tank with adequate dosage of PAC and PAM were adopted based on limited footprint and strict effluent quality requirement, and the process was followed by a Hydro-Clear shallow media rapid filter, which achieved the goal that the TP and SS in the effluent were no more than 0.3 mg/L and 5 mg/L, respectively. The project was operated formally in January 2020. The average SS in the effluent was 2.7 mg/L, which stably met the design standard of SS no more than 5 mg/L. During the operation of shallow media rapid filter, the proportion of backwash water was less than 2%, and the direct operating cost including consumption of electricity and chemicals was 0.004 5 yuan/m3.
