Initially Searches on Environmental Management Present Situation and Prevention and Control Countermeasures for Pollution of Jilin Province Sewage Treatment Plants

吉林省有污水处理厂20座,以城镇污水处理厂居多,约占吉林省污水处理厂总座数的75%。主要削减的污染物为第二类污染物,并以化学需氧量和生化需氧量削减量最大;吉林地区污水处理厂化学需氧量和生化需氧量削减量最大,其次为长春和四平地区,辽源地区污水处理厂化学需氧量削减量最小;松花江流域污水处理厂化学需氧量削减量最大,其次为辽河流域,再次为图们江流域。松花江流域污水处理厂生化需氧量也是削减量最大,其次为辽河流域,再次为图们江流域;全省第二类污染物削减率为79.46%。针对吉林省污水处理厂污水及污水中污染物处理情况,加强全省污水处理厂的能力等各方面建设势在必行。

Major reduced pollutants is the second category of pollutants. Amount of re- duced chemical oxygen demand and biochemical oxygen demand are maximum;Amount of reduced chemical oxygen demand and biochemical oxygen demand of the sewage treatment plants in Jilin are the largest, followed by areas of Changchun and Siping, that of sewage treatment plants in Liaoyuan area is the least. Amount of reduced chemical oxygen demand of the sewage treatment plants in Songhua River basin is maximum, followed by Liao River basin, again for the Tumen River basin. Amount of reduced biochemical oxygen demand of the sewage treatment plant in Songhua River basin was also reduced maximum, followed by Liao River basin, again for the Tumen River basin; the Province＇s second category pollutant is reduction rate of 79.46%. For the treatment circumstances of wastewater and pollutants in that in Jilin Province sewage treatment plants, it is imperative to strengthen the capable construction etc. of the province＇s sewage treatment plants.
