基于水质分析模拟软件浅析北塘排污河的污染负荷减排

Analysis of pollution load reduction in beitang sewage river based on water quality analysis simulation program

在全国各城市的黑臭水体基本消除的情况下,个别城市仍存在着水质问题严重的纳污河道。文中简单阐述了水质分析模拟软件(water quality analysis simulation program,WASP)和日最大污染总负荷(total maximum daily load,TMDL),并介绍了它们的应用进展,运用WASP模拟计算了水环境容量,结合TMDL分析了北塘排污河的负荷减排。研究发现Seg3河段为污染负荷最严重的区域,东郊污水处理厂、南陀村排污河闸口和东丽湖闸为污染负荷最严重的排污口,以此为管理者分析负荷减排与分配提供建议。

Under the circumstance that the Black and Odorous Water Bodies in all cities across the country have been basically eliminated,there are still sewage-accepting rivers with serious water quality problems in individual cities.This paper briefly expounds the Water Quality Analysis Simulation Program and Total Maximum Daily Load,and introduces their application progress.Using WASP to simulate and calculate the water environment capacity,combined with TMDL,the load reduction of Beitang sewage river is analyzed.This study found that Seg3 is the area with the most serious pollution load,and Dongjiao Sewage Treatment Plant,Nantuo Village Sewage River Gate and Dongli Lake Gate are the most serious sewage discharge outlets,so as to provide suggestions for managers to analyze load reduction and distribution.
