Research On The Water Environmental Capacity In Bengbu Urban Section Of Huai River

Environmental capacity is a basic quantity of environment self-purification which reflects the disciplinarian of transference and translation of contamination and also reflects the receiving capacity under a certain kind of environment. The water environmental capacity is the control planning of waste water pollution, basic theory for simulating the water quality and mapping out the prevention and cure.Based on the flow characteristics, the water quality model is established by the use of one dimensional model Water quality model coefficient is also identified.Improve the revering hydrographic information and the situation that the pollutant ,COD(Chemical Oxygen Demand), NH3-N imports the riverain aqua, according to the riverain functional area and corresponding water-quality standard, calculate the Huai River's clarification coefficient for COD ,NH3-N and permission import COD quantity. According to the handling unit COD cost for various sewage under different scales, cultivate handle-cost, add water-quality restrictive equation, production restrictive equation and variable restriction, form a linear planning in order to decide every let meatus scissoring quomodo.The determination of environment capacity in Huai river is capable of simulation and forecasting the water quality, providing basal for data for total pollutants control and scientific basis for pollution management.
