The Wastewater Treatmint Plants A Feasibility Study For The Using Reclamation Of Estate Compost

In recent years, as the urbanization and the protection of water resources planning projects are started one after another, urban sewage treatment facilities are speed up the pace then, and sewage treatment rate is increasing over the years. The amount of sewage sludge is obviously increasing ,therefore, the treatment and disposal of the sewage sludge is increasing apparent. The urban sewage treatment plants, most of the sludge has not been at a stable, sound and resources of the treatment and disposal, and not only become the urban sewage treatment plant burden, and the uncontrolled discharge of sludge and pile to surrounding environment has been startling. The most cost-effective disposal of sludge in the form is biological resources recycling, or disposal of sludge used of resources after many factors to consider. The sludge composting use of the resources of the program is proposed to solve this problem. And the sludge treatment and disposal, sewage sludge fertilizer are together to achieve integration of the sludge treatment and disposal and recycling of biological resources. Then it can achieve the social, economic and environmental benefits of unification.Feasibility Study is based on the investment decision-making and project development pre-feasibility study on the quality determine the success of the project in the future directly. Focusing on the use of sewage sludge composting resources to the development of industry analysis proceed, based on the urban sewage treatment plant sludge for the study, and in strict accordance with the basic principles of a feasibility study. First of all, this article analyzes the current sewage sludge treatment and disposal of the status quo and the problems, and these reflect the status of the project's research background; secondly analyzes the property of the sludge ,and starting to carry out a sewage treatment plant sludge composting of the feasibility of the use of resources, which analyzed the majority of urban sewage sludge Organic matter, nitrogen, phosphorus, potassium, and other toxic heavy metals and hazardous substances, in line with urban agricultural sludge standards, and the Organic fertilizers also have high market-wide, from the macro aspects of the selection of sludge composting resources utilized in our line is feasible; thirdly, the fertile soil in Shanxi project works as a case that the choice of sludge composting is the use of resources With the implementation of the can; and, from a technical and economic analysis of the feasibility of the project; Finally, the overall assessment of the project, at the same time, the sludge composting prospect and came to the conclusion of the feasibility of The study concluded.
