基于数值模拟的雨水泵站放江污染控制研究
Study on Pollution Control of Rainwater Pumping Station Discharge Based on Numerical Simulation
摘要
Abstract
In order to study the pollution control of rainwater pumping station discharging into the river,the drainage process of a rainwater drainage system in Shanghai was studied by establishing a hydrodynamic water quality coupling numerical model and using the method of numerical simulation.The improvement effect of engineering measures was discussed,such as improving the interception capacity,rain sewage mixing transformation and building a storage tank on the river discharge pollution of the pumping station.The results showed that after improving the interception capacity,the river discharge volume will be reduced by 6％～17％in case of 25mm to once-in-a-year rainfall.After the rain sewage mixing transformation was fully implemented,the upper limit of non-discharge rainfall of the pumping station can be increased from 12mm to 25 mm,and the reduction of pollutant discharge can reach 21％～28％when the rainfall is 33mm to once-in-a-year.Building a storage tank can raise the upper limit of the non-discharge rainfall of the pumping station from 12mm to 33mm,and reduce the discharge of pollutants by 45％～49％in case of rain once-in-a-year.The methods and results of this research can provide a basis for the operation and management of municipal drainage networks and the decision-making of government to formulate measures for pumping station river discharge.关键词
