通过对传统工艺中的普通滤池进行生物强化 ,可以使原水中氨氮 (NH3-N)的去除率由原来的 30 %～ 4 0 %提高到 93% ,亚硝酸盐氮 (NO- 2 -N)的去除率由零提高到 95% ,有机物(CODMn)的去除率由 2 0 %提高到 4 0 %左右 ,出水浊度保证在 1NTU以下 ,经消毒后能满足卫生学指标的要求。经长期运行测定 ,在滤速 1 0m/h、反冲洗 ( 1～ 2次 ) /d情况下依然保持良好的处理效果。该技术不增加任何新设施 ,只是强化现有工艺 ,是解决微污染源水水质的一项新途径。
The biofortification of common filter in traditional process can improve the removal rate of ammonia nitrogen (NH3-N) in raw water from 30% ~ 40% to 93%, nitrite nitrogen ) Removal rate increased from zero to 95%, the removal rate of organic matter (CODMn) increased from 20% to 40%, and the effluent turbidity was below 1NTU, which could meet the hygiene requirements after disinfection. After long-term operation, the filtration rate is maintained at 1 0m / h and backwashing (1 ~ 2 times) / d for a long time. The technology does not add any new facilities, just to strengthen the existing process is to solve the slightly polluted source water quality of a new way.
