Investigation on Water Pollution Control of Drinking Water Source in China

Abstract Drinking water source is an important guarantee of domestic for urban residents, which has been affected mainly by non-point pollution and aroused widespread concern in various countries. However, with the change underlying surface types, there are significant differences control strategies. In this study, two strategies were proposed typical conditions high-density built-up agricultural source, respectively. It considered that area can be divided into ecological area. The stormwater runoff from intercepted transferred to reservoir directly. But treated three situations: rainfall less than 7 mm, greater mm 50-year return period period. Correspondingly, intercepting ditch, embedded reservoir, constructed wetland deep tunnel applied. Differently, strategy land right circulation taken reduce pesticide pollution. Further, load entering reduced near-natural wetland, isolation zone floating debris interception. At same time, help superior natural resources, industry developed achieve balance protection development based on EOD. research results provide valuable reference treatment reservoirs.
