Abstract

Abstract: The work of comprehensive improvement for urban rivers has been put on the daily agenda. This paper introduces in detail a comprehensive treatment scheme integrating anti-pollution, treating-pollution and monitoring maintenance in views of both the perspective of technological process and the analysis of pollutant causes. The most important thing of pollution prevention is to prevent pollutants from entering the river again. Means such as low impact development technology and laying pipelines to collect wastewater for intercepting can be adopted. The most important process of pollution treatment is dredging sludge of rivers in time and repairing water body by using ecological principles. The process of monitoring and maintenance includes monitoring of water quality in real time, regular monitoring of water ecosystem, monitoring of normalized pollutants and timely cleaning of garbage and removal of various pollution sources, which could guarantee and maintain the river's healthy state. The three steps of river improvement promote each other and form a circular relationship. According to this scheme, the comprehensive improvement for urban rivers needs the participation of government, enterprises, society and residents, which may achieve the ultimate goal of sound ecological balance of the ecosystem. In addition, this paper gives the simple operation process of river improvement and the simple idea of sludge treatment, which provides valuable reference for improving the water treatment system.
