MSBR工艺调试与运行控制策略研究
- Title:
- Research on MSBR Process Commissioning and Operation Control Strategy
- Keywords:
- MSBR process; upgrading and renovation; commissioning and operation; nitrogen and phosphorus removal; energy conservation and efficiency enhancement
- 摘要:
- 嘉兴市某污水处理厂提标改造工程采用MSBR工艺，总处理规模为10×104 m3/d，出水水质执行浙江省《城镇污水处理厂主要水污染物排放标准》（DB33/2169—2018）的现有污水处理厂标准。对工艺调试过程进行总结，研究了MSBR工艺进水水质波动及工艺参数变化对COD、TP、NH4+-N及TN去除率的影响；采用多元线性回归法进行多因子分析，并基于Python中的SALib开源库对工艺关键运行参数进行敏感性分析，给出工艺运行控制策略。与传统A2/O工艺相比，稳定运行期间MSBR工艺的药剂消耗量和耗电量均更低。
- Abstract:
- The upgrading and renovation project of a wastewater treatment plant (WWTP) in Jiaxing adopts the MSBR process, with an overall treatment capacity of 10×104 m3/d, and the effluent quality complies with the criteria for existing WWTP in Zhejiang Province local Discharge Standard of Major Water Pollutants for Municipal Wastewater Treatment Plant (DB33/2169-2018). The commissioningprocess is summarized, and the influence of inlet water quality fluctuation and process parameter changes on the removal efficiencies of COD, TP, NH4+-N, and TN are studied. The multiple linear regression method was used for multifactor analysis, and sensitivity analysis was conducted on key operating parameters of the process based on the SALib open-source library in Python, to summarize the process operation control strategy. Compared to traditional A2/O process, the MSBR process consumes lower amounts of reagents and electricity during stable operation.
