摘　　要：生物法处理含铁锰超标地下水具有工艺简单、出水水质稳定、成本低、二次污染少等优点。该文在秋冬季和春夏季考察了锰砂、沸石滤料处理模拟地下水中铁锰的效果及可行性。实验结果表明:在秋冬季,锰砂和沸石滤料对铁的去除率为85%—99%,除铁效果好于除锰,锰砂滤料除锰效果好于沸石滤料;在春夏季,在试验装置重启后的前期,锰砂及沸石滤料除铁效果开始转好;在调控运行的后期,两种滤料对锰的去除效果均值为90%;整体而言,锰砂滤料对铁锰去除效果要好于沸石滤料。The biological method has the advantages of simple process,stable water quality,low cost and low secondary pollution.This paper investigated the effect and feasibility of manganese sand and zeolite filter media treatment on the iron and manganese in simulation groundwater in the autumn-winter and spring-summer.The results show that in autumn-winter,the removal rate of iron by manganese sand and zeolite was 85%-99%;the effect of iron removal was better than manganese removal;manganese sand filter material had a better effect on removing manganese than zeolite filter material.In spring-summer,the effect of iron removal of manganese sand and zeolite filter material began to be better in the early stage after the test device was restarted.In the late stage of regulation and control,the average removal efficiency about the manganese of two kinds of filter material was 90%.Overall,effect of manganese sand filter material on the removal of iron and manganese is better than the zeolite filter material.
