摘要
以兰州市雁儿湾污水处理厂实际运行资料为背景,对污水处理厂冬季和夏季污水处理效果进行比较分析。研究发现:污水处理厂对COD的平均去除率在79%左右,对BOD的平均去除率在87%以上,均能保证出水达标,对COD和BOD的去除效果冬季和夏季无明显差异,对SS的去除效果夏季优于冬季。研究结果对城市污水处理厂的设计具有重要的指导意义和实用价值。
Taking actual running of Yanerwan Wastewater Treatment Plant in Lanzhou City as example, effect of wastewater treatment in summer and winter was compared and analyzed. Results showed that average removal efficiency of COD and BOD was around 79% and 87%, both of which can meet discharge standard. Removal efficiency of BOD and COD was almost the same in summer and winter, while that of SS in summer was better than that in winter. The study had a directive and practical importance to design of wastewater treatment plant.
