The Balance Of Water And Zero Discharge Of Wastewater System For Power Plant

With the serious lack of the water resources, the suitable treatment of fresh and wastewater in the power plants is significative of saving water. The paper reviews the zero discharge and give a conclusion. At the same time, some personal ideas was gave for our country. The major ways in processing zero discharge: increasing the concentrate ratio of the cooling system, and decreasing drain; reusing the wastewater of the cooling system; rebuild the ash-sluicing system; developing the technics for the desulfurization wastewater; optimizing technology of water system operation.The Power plant has eight unit of 300MW, which completely used underground water. The research gives the detailed data about use and release water in the power plant. According it, the balance of water are clear, followed by estimation of all kinds of sub-system. We attempt a testing for the vaporization and leakage of cooling system in different time and generate electricity load. The results have a great effort for water management and practice function.We choose some corrosion inhibitor and antisludging agent to obtain concentrate radio of 4.Weighe-lost method, electrochemical test was used in medium sized experimentation. At the base of the future plan of the power plant and the data we have got, a serious of program suggested in order to carry out the zero discharge plan. Zero discharge system of wastewater is a relative complex system engineering in managing otiose run,give off, the leakage lose etc. It is only a short study under the existing technical situations.
