Research Progress in Water Quality Improvement

Abstract

Rivers play an important role in flood control, sewage discharge, ecology, and so on. However, the intensification of water pollution leads to the river water quality to gradually decline, and pollution control cannot be delayed. This article analyzes the water environment from water quality improvement method. The water pollution treatment and improvement are analyzed and it points out the advantages and disadvantages from physics, chemistry and biology. The article also combs and summarize the issues and development trends in the river water quality improvement method in order to provide scientific reference for the improvement water quality assessment and comprehensive treatment of water pollution of rivers.
