摘要
以中南民族大学喷泉池水为研究对象,对微污染景观水体的治理方法及工艺进行了深入讨论,分析了景观水体富营养化的成因,提出了一套优化的组合式治理工艺:曝气+絮凝+加氯.经该工艺处理后出水CODMn、NH3-N、色度及浊度分别达到2mg/L、0.40mg/L、2及1,均达到景观水质C类标准.表明该组合工艺对微污染的景观水体治理具有较高的应用推广价值.
In this paper, the ways of scenery-water treatment are studied using the water in the fountain of South-Central University for Nationalities. The origin of eutrophication is also disscused and a system composed of air aerating, flocculating and adding chloring dioxide technology is proposed to treat the scenery water. COD_(Mn), NH_3-N, colour and turbidity of the effluent were below 2mg/L,0.40mg/L, 2 and 1 separately. The water quality of the effluent is better than the C standard of the water quality standard for scenery and recreation area. The conclusion that the composed technology is worthextending is gotten.
