摘要
邯郸市西污水处理厂采用厌氧选择池/改良氧化沟工艺处理城市污水,但由于实际进水水质与设计值有偏差,造成运行管理困难且费用较高。针对该厂的实际运行情况,探讨了曝气系统的DO、MLSS、泥龄等运行参数的控制问题,并对各参数进行分析、优化调整,最终使该工艺具有较好的脱氮除磷效果。
Anaerobic selection tank and modified oxidation ditch process are used in Western Wastewater Treatment Plant in Handan City. Because the practical influent quality was different from the design value, the operation management was difficult and the cost was high. Aimed at the practical operation situation of the plant, the control problems of operation parameters, such as DO in aeration system, MLSS, sludge age and so on are discussed. By analyzing and optimally adjusting the parameters, the good effects of nitrogen and phosphorus removal are obtained,
