摘要:
针对某市H区污水厂、站、库经过水量调配后，GS水质净化厂（一、二期）进厂BOD5浓度不断降低的问题，对H区“厂站网河库”体系进行排查和分析。通过对进厂BOD5浓度影响的关键因素进行定性定量分析，结合调度前后污水厂进水水质指标及管网的液位、流量、B/C比、C/N比等特性，明确主要问题，并为厂站库调度运行、BOD5浓度变化提供经验数据。研究结果显示，该区隐患问题总水量约11.6×104 m3/d，拉低了H区总进厂BOD5浓度17.29 mg/L；厂站库调度使H区总进厂BOD5浓度下降了7.14 mg/L；受低浓度工业废水及供水企业尾水影响， H区总进厂BOD5浓度降低1.6 mg/L。受疫情影响，与调度前相比，供水量下降1.52×104 m3/d。因此，H区优先解决倒灌点、打开总口最为重要，其次解决雨水进入污水系统问题；在厂站网库调度方面，应进一步推行厂站网河库一体化运维体系。
Abstract:
In view of the observed decline in BOD5 concentration in the GS wastewater purificationplant (phase I and phase Ⅱ) following the allocation of the WWTP, pump station, and reservoir water in the H district of a city, an investigation and analysis of the “WWTP-pump station-sewer network-river(reservoir)” system in the H district is conducted. Through qualitative and quantitative analysis techniques, the key factors affecting the influent BOD5 concentration can be effectively identified. This is achieved by integrating the water quality indicators of the WWTP with the characteristics of the water level, flow, B/C ratio, and C/N ratio of the pipe network, both before and after the dispatching operation. The empirical data can be utilized to enhance the dispatching operation of WWTP and facilitate a more accurate prediction of the BOD5 concentration. The research results show that: ① The total wastewater volume of potential problems in this area is about 11.6×104 m3/d, total influent BOD5 concentration in H district decreased by 17.29 mg/L; ② The total influent BOD5 concentration has been reduced by 7.14 mg/L due to the scheduling of WWTP, pump station, and reservoir; ③ The impact of low-concentration industrial wastewater and tailwater of waterworks will reduce the total influent BOD5 concentration by 1.6 mg/L; ④ Affected by the epidemic, the water supply decreased by 1.52×104 m3/d compared with that before scheduling. Therefore, it is most important to prioritize addressing the backflow of river water and opening the main outlets in H district, followed by resolving the problem of rainwater entering the sewage system. In terms of scheduling of WWTP-pump station-sewer network-reservoir operation, the integrated operation and maintenance system of WWTP-pump station-reservoir should be further promoted.
