Research on status analysis of surface water environment and pollution control in Jiaozuo city

Investigation and study show that the surface water pollution of Jiaozuo city is serious, the river water quality is V or above V. The total sewage export loads are 13130.42 tons every year, export loads of the main pollutants CODCr are 32846.15 tons, and the NH3-N are 3591.37 tons every year. In this research, the water quality requirements of each function as the water environment pollution controlling ,according to the characteristics of surface water pollution, selecting one-dimensional model and zero dimension model of surface water carrying capacity is calculated, and have got the controlling quantity and reducing quantity of pollutants in different level years, and provided the scientific basis for the prevention and control of water pollution for sustainable utilization of water resources Jiaozuo city.
