Project Feasibility Research Of Treatment Of Some Municipal Development Zone Sewage

In recent years, environmental pollution is more and more serious. In entire environment, the water environment worsening causes person to pay close attention to especially. With the improvement of living standards and economic and social development, the resulting volume of sewage waste water is also growing, but in many cities, sewage is not well collection and processing. Led to many of the receiving water beyond its own self-purification ability, which created a significant environmental impact. Drainage network and the construction of sewage treatment plants will largely alleviate this problem.With the development of sewage treatment technology, a variety of increasingly sophisticated technology, what treatment handicraft to is chooses, is becomes the core that the decision-makers construction sewage treatment factory shows solicitude for. In addition, as the sewerage system, drainage network construction is also essential. In this paper, a great deal of relevant data collection and analysis, based on local conditions, raised the drainage system-building programs.In comparison of domestic wastewater treatment processes, the selection of oxidation ditch process and CASS process as an option. This article also made the two options for engineering design, and designed to do an economic comparison, the last comprehensive consideration of a series of techno-economic and environmental factors to determine the oxidation ditch process for the recommended program.With a further increase in water shortages, water reuse technology, water reuse in the construction of the sewage plant is possible. In this paper, wastewater reuse has also done the design, comprehensive consideration of various factors, chosen as the flocculation direct filtration water treatment program as a back.Look at this study is mainly to solve these four problems:1. Yanliang National Aviation Industrial Base under the general plan and proposed urban sewage pipe network, sewage plant site, as well as wastewater treatment plant process design.2. On the proposal for technical and economic comparisons, and choose to determine the best option.3. For recommended program process, structure, building, electrical, instrumentation, automation, and heating ventilation for program design.4. The economic evaluation estimating that the project invests and being in progress is analysed..
