摘要
针对福州市某污水处理厂存在进水水质冲击导致出水部分指标存在超标风险且工艺运行中存在能耗高的现象,通过模拟不同水质与运行条件下模拟中试装置的处理效果优化工艺运行.结果表明,控制生化系统HRT为17 h,MLSS质量浓度维持在3 000～4000 mg/L,DO质量浓度维持在1.78～2.12 mg/L,新型除磷药剂投加量为2.3 mg/L,出水水质中主要污染物可稳定达一级A标准.
Abstract
In response to the risk of exceeding certain effluent indicators and high energy consumption during process operation caused by water quality shock in a sewage treatment plant near an industrial park in Fuzhou,the process operation was optimized by simulating the treatment effect of a pilot plant under different water quality and operating conditions.The results showed that by controlling the HRT of the biochemical system for 17 hours,MLSS was maintained at 3 000～4 000 mg/L,DO was maintained at 1.78～2.12 mg/L,and the dosage of the new phosphorus removal agent was 2.3 mg/L,the main pollutants in the effluent water quality could be stabilized to meet the first-class A standard.
