摘要
为研究不同生态措施对河道水质净化的效果,本文通过生态河道、人工湿地以及生态池三种修复措施对山东乐陵漳卫新河水质净化前后的效果进行了对比试验分析。结果表明:生态池去除TP效果最佳,而人工湿地则对COD和TN的去除效果最佳;生态池和人工湿地对水力负荷变化的适应能力较强,去除率与水力负荷的相关性不大;综合修复系统、人工湿地以及生态池的出口,COD和TP浓度与污染负荷呈正相关,TN的浓度则与污染负荷无明显关系。研究结果可为当地河道的生态治理工作提供借鉴。
Comparative test analysis is conducted on the effect before and after water quality purification in Shandong Leling Zhangweixin River in the paper through three restoration measures of ecological river channel,artificial wetland and ecological pond in order to study the effect of different ecological measures on river water purification.The results show that the ecological pond has the best removal efficiency of TP,while the artificial wetland has the best removal efficiency of COD and TN.Ecological pools and constructed wetlands have relatively strong adaptability to hydraulic load changes,and the correlation between removal rate and hydraulic load is not significant.COD and TP concentration is positively correlated with the pollution load in comprehensive restoration system,artificial wetland and ecological pond outlet.TN concentration is not significantly correlated with the pollution load.The research results can provide reference for the ecological management of local rivers.
