摘要:
城市的发展和人口的增加,直接导致了污水排放量的增加。本文以溧阳市新建排污口为研究对象,在分析排污口进出水水质及北河现状水质的基础上,将河流进行合理概化,对设计流量、初始浓度、综合衰减系数等参数进行合理取值。以污染物化学需氧量(CODCr)和氨氮(NH3-N)为例,利用一维水质模型计算入河排污口对北河的影响范围。结果表明,正常排放时,CODCr 和氨氮的混合区长度分别为11010 m 和15696 m,污水回用30% 后排放影响范围分别减小18.66% 和1.79%,事故排放情况下污水影响范围显著增大,分别为正常排放的1.72 倍和1.43 倍。
Abstract:
The increase of population and the development of the city,directly led to the increase of sewage emissions.The new outfall in Liyang City was set as the research object.Based on the analysis of the sewage outfall water quality and current water quality of the North River,the river is reasonably generalized,reasonable value of parameters such as flow,initial concentration and integrated attenuation coefficient was suggested.Taking the chemical oxygen demand (CODCr) and ammonia nitrogen(NH3-N) as an example,the influence of the sewage outfall on the North River is calculated by using one- dimensional water quality model.The results showed that the normal discharge,the length of the mixed zone of CODCr and NH3-N were 11010m and 15696m.After the wastewater reuse 30%,the influence length decreased by 18.66% and 1.79% respectively.In the case of accident discharge,the influence length was increased significantly,which was 1.72 times and 1.43 times that of normal discharge.
