| 摘 要： | 以江苏省某市污水厂最终出水模拟水池及实际受纳景观水体为研究对象,主要考察水力停留时间、氮、磷营养物对叶绿素a的影响。实验结果表明:水力停留时间越短,叶绿素a浓度越低,富营养化的程度越低;水中磷酸盐浓度是藻类生长的主要限制因素,pH、DO值可以作为景观水体富营养化的预警指标。同时对有再生水补充的景观水体和没有再生水补充的景观水体进行监测对比,得出再生水补充景观水体缓解水体富营养化程度上有很好的效果。

| Abstract: | In this study the final effluent of a Jiangsu wastewater treatment plant and the receiving water body was chosen for research object.The effect of the hydraulic retention time,nitrogen and phosphorus nutrients on chlorophyll a was studied.The experimental results showed that the shorter the hydraulic retention time,the lower the chlorophyll a concentration,the lower the degree of eutrophication;algal growth was mainly influenced by concentration of phosphorus in water,and pH,DO value can be used as a warning index for eutrophication.At the same time two landscape waters were monitored,one was add reclaimed water,the other was not,it was concluded that reclaimed water added to landscape water has a good effect in relieve the eutrophication. |
