Study on Distribution of Pollutants Reduction in Black and Odorous Water Bodies in Rural Areas
With the continuous development of urban and rural economy and the improvement of people's living stand-ards,pollution problems in rural areas have become increasingly prominent,among which black and odorous water bodies are a major problem.In order to improve the quality of water environment and orderly carry out the treatment of black and odorous water bodies in Xishui County,the pollution load of black and odorous water bodies in Xishui County was calculated.Based on the water environment capacity of black and odorous water bodies in rural areas,the reduction a-mount of each control unit was calculated,and the hierarchical distribution of the reduction amount of pollutants was studied.A reduction allocation model was established to determine the main pollution sources of different water bodies and the corresponding reduction amounts of different pollution sources,and improve the effect and sustainability of pollu-tion control so as to achieve accurate and scientific pollution control.
