摘要
通过对津河河段上6个监测点进行采样,测定了其7个水质参数:透明度、色度、溶解氧、化学需氧量、生化需氧量、总磷、总氮,以此对天津市津河水质进行分析.结果表明:透明度、色度、溶解氧均符合景观娱乐用水标准;而化学需氧量、生化需氧量、总磷、总氮均有超标现象,水体出现富营养化.根据津河水体的这一特征,分析了水体污染负荷的来源,并提出了改善津河水质的几点建议.
Six sampling stations were selected at Jinhe River and Seven water quality parameters were measured which include transparency, chromaticity, Dissolve Oxygen （DO）, Chemical Oxygen Demand （ CODcr, ）, Biology Oxygen Demand （ BOD5 ）, Total Phosphorus （TP） and Total Nitrogen（TN）. The results showed that transparency, chromaticity and DO were in accordance with the water standard of landscape and amuse, but CODcr, BOD5 ,TP and TN were all higher than standard and the water has emerged eutrophication. Finally, according to the characteristics of Jinhe River and the origin of the pollutants , some good suggestions on the water quality maintaining were made.
