Research On The Sewage Rreatment System And Layout Of Tianjin Port Industry Park

With the high-speed development of the industrial economy,the water pollution of our country has been in a grim situation. Urban sewage treatment system is an important part of the city auxiliary infrastructure facilities, which plays a significant role with the water pollution control. It is necessary to accelerate the urban sewage treatment infrastructure construction and promote their efficient operation. At present, the urban sewage treatment system layout consists of two modes: centralized and distributed, with the centralized primarily. The reasonable, economy of the urban and the actual development in the region determine the effect of the sewage treatment system after construction.The planning of the sewage engineering is being planed in Tianjin port industry area whichi is a new functional area of Binhai new area, the total volume od the planning sewage reach to 54.5 tons, mainly includes sanitary sewage and the industrial wastewater. In this paper, an analysis of the centralized and distributed sewage treatment system's concept, characteristics, development situation, existing problems and construction cost is carried out on the base of the actual data.According to the natural conditions, lia land condition, overall layout, the plot of land, the usage of land and water supply system, a centralized sewage treatment system, a distributed sewage treatment system and a relative centralized have been designed, a comparative analysis of the three cases have been made based on the cost of construction and operation and the environmental benefits.The results of the analysis indicate that relative centralized sewage treatment system has more advantages than other schemes, and more suitable be used in the Tianjin port industry area.
