摘要
研究锰砂滤层去除铁、锰过程中温度、溶解氧两个因素对去除效果的影响,为生物法除铁、锰的实际运行提供了参考依据。从经济性和微生物角度考虑,原水DO维持在3 mg/L左右即可满足运行要求,采用跌水曝气的方式去除效果优于管道混合器。当铁锰共存时最适宜的处理环境温度为20℃。
The paper discusses the technology of removing manganese and iron from groundwater by biological filter media. We have tested temperature and dissolved oxygen to influence the manganese and iron and drawn the conclusion through the test that the DO level around 3 mg/L is good enough and the most suitable environment temperature is 20℃ when iron and manganese coexist.
