摘要
利用生物过滤处理微污染原水,分析了生物膜特性和生物相,对生物膜去除有机物、氨氮、铁、锰等的机理和生物膜净化作用特征进行研究.微污染原水中的氨氮和有机物是通过吸附、吸收、代谢、排出而得到去除的,其去除率分别为88%和30%,对铁的去除主要是接触氧化和生物的共同作用的结果,其去除率可达到94%以上,对锰的去除主要是依靠锰氧化细菌的催化作用,其去除率在90%以上.
Micro-polluted raw water was treated by biological filter. The mechanism of bio-film in eliminating organic matter, ammonia nitrogen, iron and manganese was studied based on the analysis of bio-film and biological phase. Ammonia nitrogen and organic matter in the raw water were eliminated through absorption, assimilation and metabolism, whose removal efficiencies were 88 % and 30 %,respectively. The elimination of iron was through the co-effect of contacting with oxygen and microbe, its removal efficiency reached 94 %. The elimination of manganese was through catalytic action of bacteria, and it＇s removal efficiency was above 90%.
