城市污染河湖的综合整治技术及应用研究

Comprehensive Renovation Technology of Urban Polluted Rivers and Lakes and Its Application

分析了城市污染河流和湖泊污染的原因,将污染河流和湖泊治理的方法分为"物理法、化学法、生物法、生态法"共四大类,介绍了常用技术方法的原理和特点。根据河流和湖泊的污染现状和治理目标,提出了城市污染河湖的综合整治分为"治理"与"生态修复"两个阶段,探讨了采用"截污、清淤、曝气、生物载体、水生植物"等综合应用技术治理河湖的必要性和迫切性,并结合近年来国内河湖综合整治的典型案例,总结了河湖整治过程的"基础措施"和"关键措施"。

This paper nalyzed the causes of urban polluted rivers and lakes. The treatment methods of polluted rivers and lakes can be divided into four major categories,include ＂physical method,chemical method,biological method and ecological method＂. This paper introduces the principle of common technical methods and characteristics. According to the present situation and goal of river and lake pollution,it put forward comprehensive improvement of urban polluted rivers and lakes can be divided into＂governance＂and＂ecological restoration＂. It also discussed the necessity and urgency of adopted＂sewage,desilting,aeration,biological carrier,aquatic plants＂governance integrated application technologies and applied to the urban polluted rivers and lakes,and combined with the typical cases of domestic comprehensive improvement of rivers and lakes in recent years,summarized the renovation process consist of＂basic measures＂and＂key measures＂.
