Abstract
In order to meet the increasingly stringent environmental policy requirements,it is of great significance to carry out the research on in-depth water conservation and zero discharge technologies for gas turbine power plants.In this paper,the water intake,discharge and consumption,as well as the water balance in a gas turbine power plantare analyzed.Based on the situation that the gas turbine power plant does not have a system of desulfurization,coal handling and deslagging that is able to consume high salinity waste water,an in-depth water conservation and zero discharge method is proposed.First,by improving the make-up water quality for the circulating system,the concentration rate is increased,and the water intake and discharge are substantially reduced.Second,the circulating sewage and reverse osmosis concentrate are concentrated by stages to reduce the high salinity waste water.At last,the small amount of high salinity waste water are evaporated and crystallized.Thus,the waste water zero discharge is achieved.关键词
