It is significant to build municipal sewage treatment facilities in cities, especially in large cities, both for the sustainable development and for the environmental protection, especially in large cities. This paper analyzes the spatial pattern, changing trends and the environmental impact of specific pollution sources. Taking Huai’an City of Jiangsu Province for example. The demand for sewage treatment facilities in the future is calculated, based on which a match between municipal treatment capacity and sewage discharge is built. Township is taken as the evaluation unit in the study. Then, the characteristics of wastewater discharge are drawn, along with the actual ability and designed capacity of the wastewater treatment facilities. Considering all of the three aspects mentioned above, the study area is divided into three types, including the type of sewage treatment potential released, the type of sewage treatment enhanced, the type of status maintained. ArcGIS spatial analysis method is necessary in the study. By comparing with the quantity of wastewater discharge, the potential capacity of treatment facilities obviously gets asked. In the future, the facilities standard need to be rebuilt and expanded in order to enhance governance ability of controlling the regional waste water, especially in the townships with multiple population concentrating, urbanization and industrialization fastest growing. Townships at the edge of urban area need to maintain the status quo of sewage treatment facilities and pipe network for future demands. Furthermore, those scattered in industrial enterprises agglomeration area, such as industrial parks, economic development zones, need to strengthen the sewer network and related infrastructure facilities construction for releasing the potential of sewage treatment. Based on that, guidance is proposed for promoting the efficiency of the building and operating of sewage treatment facilities, and then it may provide scientific basis for site selection and layout optimization of municipal sewage treatment facilities.
