摘要:
中央一号文件明确提出了水功能区限制纳污等“三条红线”,入河排污口的设置受到更严格的限制和监督。以溧阳市南渡污水处理厂新建排污口为研究对象,分析复杂水文条件下,对河流进行多节点分段概化,对断面浓度、设计流量、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,利用一维水质模型分段计算入河排污口对北河及相关水功能区的影响。结果表明,在最不利水量条件下,正常排放时对所在水功能区、相邻水功能区及下游水功能区水质均有一定影响;污水回用30%后排放时影响范围缩小,对下游相邻水功能区水质基本无影响;事故排放时影响程度显著增大,进入饮用水源区的CODCr和氨氮浓度分别为正常排放的1.2倍和1.4倍。
Abstract:
The No.1 Document of the Central Committee clearly put forward the “three red lines” such as limited pollutant carrying capacity of water function area, and the installation of sewage outlets into rivers was subject to more stringent restrictions and supervision.Taking the newly-built sewage outlet of Nandu Sewage Treatment Plant in Liyang City as the research object, the multi-node segmental generalization of the river under complex hydrological conditions was analyzed, and the parameters such as section concentration, design discharge and comprehensive attenuation coefficient were reasonably selected.Taking the pollutant chemical oxygen demand (CODCr) and ammonia nitrogen (NH3-N) as examples, the one-dimensional water quality was utilized to calculate the influence of the sewage outlet on the North River and the related water function areas.The results showed that under the most unfavorable water quantity, the normal discharge had certain influence on the water quality of the water function area, the adjacent water function area and the downstream water function area.When the sewage was reused for 30%, the influence area was narrowed, and the water quality of the downstream adjacent water function area was basically unaffected.When the accident was occurred, the influence degree was significantly increased, and the concentrations of CODCr and NH3-N entering the drinking water source area were respectively 1.2 times and 1.4 times of the normal discharge.
