上海市工业河与小宅浜治理前后水质评价
|
摘要
针对上海市普陀区工业河、小宅浜治理前后水质进行评价.对河道水体中溶解氧、浊度、硝态氮、叶绿素a和浮游动物种群密度等5项指标进行单因子变化趋势分析;选取总磷、氨氮、高锰酸盐指数、化学需氧量及五日生化需氧量共5项指标进行水质灰色关联度分析.结果表明:两条河道中溶解氧和浊度在治理前后并无明显变化;硝态氮浓度在治理后先降低后升高;叶绿素a浓度显著升高;浮游动物种类及密度有所上升;灰色关联分析显示,两条河道水质在治理前接近Ⅴ类,而在治理后的短期内均曾达到Ⅰ类,但随后又有所回落并稳定在Ⅳ类.
The water quality of Gongye River and Xiaozhai River in Putuo District of Shanghai before and after treatment were evaluated in this study.Single factor trend of dissolved oxygen,turbidity,nitrate nitrogen,chlorophyl a,and population density of zooplankton in these two rivers were analyzed;in addition,grey correlation analysis was conducted with total phosphorus,ammonia nitrogen,permanganate index,chemical oxygen demand,and five-day biochemical oxygen demand.The results showed no obvious changes in dissolved oxygen and turbidity before and after treatment.The concentration of nitrate nitrogen decreased initially after treatment.The concentration of nitrate nitrogen decreased initially after treatment,but increased thereafter,meanwhile,the concentration of chlorophyl a rose significantly after treatment.There's an increase in both,species and densities of zooplankton with treatment.The grey relational analysis indicated that the water quality of the two rivers was close to Class Ⅴ before treatment,reached Class Ⅰ in the short term directly after treatment,and eventually stabilized at Class Ⅳ.
