南方某电厂生活污水处理系统试验研究

Study on Sewage Treatment in Southern Power Plants

采用曝气生物滤池和消毒池处理生活污水,以满足火电厂生活废水处理要求,研究了该系统对废水中p H影响,以及对浊度,COD和氨氮去除效果。实验结果表明,该系统可以有效实现有机物和氨氮的同步去除。出水的p H为6~9,曝气生物滤池的出水浊度可达到2.4 NTU,出水COD可达到11.4 mg/L,氨氮可达到6 mg/L左右,氨氮的去除率可达到85%。

Treat sewage with biological aerated filter and disinfecting tank, in order to meet the requirement of sewage treatment in coal-fired power plants. The effects of sewage treatment system on the pH, turbidity, COD and N-NH3 removal rate were studied. The experimental results show that the system could effectively remove COD and ammonia nitrogen. The pH was between 6 and 9. The turbidity, COD and N-NH3 of biological aerated filter effluent was 2.4 NTU, l 1.4 mg/L and 6 mg/L. The removal efficiency of NH3-N reached to 85 %.
