浦东国际机场排污现状及排污口调查分析与对策

Investigation on sewage condition and discharge outlets of Pudong International Airport and countermeasures

为能清楚地掌握浦东机场范围内的排污现状并为后续污水处理和建设管理提供依据,按区域和行业对污水排放量和水质进行了评价,结果表明:机场总污水排放量为1.12万t/d,总排污口水质中化学需氧量、5 d生化需氧量、氨氮悬浮物等4项指标均超过排放标准,其中最大污染源来自于生活污水。为此提出对策和建议:①明确污水排放处理的责任主体;②构建责任明确的运行管理和维护主体;③驻场企业可按各自特点,对污水采取分散、集中或集中与分散结合的处理方式。这样才能使驻场各单位形成共同协商、互相监督、加强约束、自我管理、稳步提高场内污水排放管理的新局面。

In order to make clear the sewage discharge situation in the area of Pudong International Airport and provide a basis for sewage treatment and construction management of the airport in future, the sewage discharge amount and water quality are an- alyzed and evaluated according to region and industry. The analysis results show that the total sewage discharge amount in the air- port area is 11.2 × 10^3 t/d, the indexes of COD, BOD5 , and ammonia nitrogen suspension and so on in the total discharge outlet exceed the standard, and the main pollution source is the domestic sewage. Some suggestions and countermeasures are put for- ward, such as making clear the responsibility subject of sewage discharge, establishing the subject for operation, management and maintenance and adopting 3 modes to treat the sewage, namely dispersion, concentration and combination of the two according to the characteristics of the departments in the field. Therefore, the relevant departments in the field could create a new situation of joint consultation, mutual supervision, more powerful restraint, and steady improvement of sewage discharge.
