The surface water bodies such as rivers and lakes are the gathering places of various sewage discharge,due to the intensification of human activities and the increase of sewage discharge,the some dilution and purification effect of rivers and lakes have been greatly weakened,exceeding the self-purification limit of rivers and lakes,causing pollutants to be deposited in the water,causing the water environment pollution of the entire basin.Water environmental pollution can be divided into water pollution caused by external pollution sources flowing into rivers and lakes and internal pollution caused by silt at the bottom of rivers.This paper expounds the problems faced by water environmental pollution in rivers and lakes and comprehensive treatment measures,and puts forward the treatment measures for water environment in river and lake basins.
