Current Situation of Water Body Pollution and Study on Standardizing Treatment Processes in Typical Region of the Downstream Watershed of New Chaobai River

摘要

Based on the project of Demonstration Research on Point Source Pollution Control of the DownstreaM Watershed of New Chaobai River, this paper selects the Baodi District section in the watershed as the object of study and conducts sampling and analysis on the water body in this section of watershed. As per the result of water quality detection, it analyzes the generation approaches of standard exceeding pollutants, determines several parameters exceeding the water quality standard such as COD (chemical oxygen demand) caused by point source enterprises, investigates pollution contribution enterprises in the upstream regions and forms COD discharge chart of industrial point sources by virtue of geographical information system (GIS). By combining water quality analysis and investigation on point source pollution enterprises, this paper preliminarily discusses the internal standardizing sewage treatment processes of point source pollution enterprises and the advanced treatment processes of industrial parks and existing municipal sewage treatment plants.
