摘要
珠江原水经两级曝气生物滤池预处理后,出水中携带有硝化细菌、异养细菌等微生物,在无预加氯情况下,产生生化延伸效应,在后续常规处理工艺中继续发挥生物净水效果。就后续常规处理工艺对NH3-N、CODMn等污染物的去除效果进行了研究分析。试验期间,生物预处理出水NH3-N平均质量浓度为0.508mg/L,沉淀池、砂滤池出水NH3-N平均质量浓度分别为0.164、0.060mg/L,其对预处理出水的NH3-N去除率分别为61.5%、84.4%。
After the pretreatment of raw water from zhujiang river, nitrobacteria, heterotrophic bacteria and some other microorganisms carried in the effluent of two-stage biological aerated filter induced continuing biochemical effect without chlorination and played the role of biological purification for the subsequent conventional water treatment process. The effect of the said process on NH3-N, CODMn and some other contaminations were studied and analyzed. It was indicated that, during the test, the average mass concentration of NH3-N in the effluent from the biological pretreatment process, the sedimentation tank and the sand filter were 0.508 mg/L, 0.164 mg/L and 0.060 mg/L respectively, the removal rate of NH3-N by the sedimentation tank and the sand filter were 61.5% and 84.4% respectively.
