摘　　要：针对在生产运行中用含氯反冲洗水冲洗除铁除锰滤池会导致去除效果变差的问题进行试验研究，考察了含氯反冲洗水对微生物除锰效果的影响。结果表明，含氯反冲洗水对滤池除锰效果具有较大的负作用，当有效氯浓度〈0．05mg／L时，其对除锰细菌的影响较小；当有效氯浓度为0．05—0．07mg／L时，其会改变除锰细菌的生活环境，降低其活性；而当有效氯浓度〉0．07mg／L时，其会抑制细菌的生长甚至杀死细菌。此外，随着反冲洗时间的延长，影响也会加大。The experimental research was conducted to solve the problem of poor removal efficiency of manganese caused by backwashing the iron and manganese removal filter with water containing chofine during the production operation. The influence of baekwashing water containing chorine on removal efficiency by microorganisms was investigated. The results show that backwashing water containing chorine has a significant side effect on the removal of manganese in the filter. The bacteria for manganese removal are slightly influenced when the available chlorine is less than 0.05 mg/L. The living environment of bacteria for manganese removal can be changed, and their activity is decreased when the available chlorine is 0.05 to 0.07 mg/L. The growth of bacteria can be inhibited, and even they can be killed when the available chlorine is more than 0.07 mg/L. In addition, the influence effect is increased with the prolongation of backwashing time.
