Study on Water-Saving Methods and Countermeasures of Developing Coal Chemical Industry in Arid Area

Coal chemical industry is one of the typical high water-consuming industries. In the coal-rich regions where are short of water resources, restriction of water resources and the environment will be bottlenecks in the development of this industry. In this paper, water-saving methods and several safe ways to deal with coal chemical industrial wastewater are studied. Afterwards, taking a coal chemical industry project area in Northwest China as an example, the feasibility of its water supply planning and wastewater treatment planning is analyzed and some reasonable suggestions are put forward, the results of which could provide scientific foundation for the development of coal chemical industry in arid area.
