Abstract:
Aiming at the present status of the recycling treatment technology of high salinity wastewater in coal chemical industry in China,its pretreatment impurity-removing technology and terminal evaporation crystal salt technology are discussed,and the technical routes on the process used in the high salinity wastewater zero discharge in China teased out. Based on a case study,the application research on the actual running effects of the pretreatment impurity removal and evaporative crystallization is accomplished,and the suggestion on process selection of the high salinity wastewater recycling treatment project proposed.
Key words:
