摘要
为了改善河道水体水质,研究基于沉水植物的河道水体水质净化生态修复技术。利用雨水原位膜过滤系统,设计河道水体外源污染初步净化工程;引进沉水植物,制作生态植物床,对水体水质进行净化处理;参照原位水生态系统,建立水生动物系统,进行河道水体的深度净化与修复处理。以南方地区某河道改善工程项目为例,进行实践应用。结果显示:基于沉水植物的河道水体水质净化生态修复技术应用效果良好,使用该方法进行河道水体水质净化生态修复,可以在提高河道水体透明度的基础上,控制水中总磷(TP)、氨氮(NH_(3)-N)含量、化学需氧量(COD)等污染物的含量。
In order to improve the water quality of river water,the ecological restoration technology of river water quality purification based on submerged plants was studied.Using the rainwater in-situ membrane filtration system,the preliminary purification project of river water exogenous pollution was designed.Introduce submerged plants,make ecological plant beds,and purify the water quality;With reference to the in-situ water ecosystem,an aquatic animal system was established to carry out deep purification and restoration of river water.Taking a river improvement project in southern China as an example,it is applied in practice.The results showed that the application effect of river water quality purification and ecological restoration technology based on submerged plants was good,and the use of this method for river water purification and ecological restoration could control the content of TP,NH_(3)-N,COD,and other pollutants in the water on the basis of improving the transparency of river water.
