Research on Water Quality Characteristics and Chemical Flocculation Treatment Technology of Shale Gas Fracturing Backflow Fluid in Weiyuan Area
The water quality characteristics of shale gas fracturing backflow fluid in the Weiyuan area were studied,and the use of chemical flocculation treatment technology in this type of sewage treatment was discussed.Through the collection and analysis of shale gas fracturing backflow samples in Weiyuan area,it was found that it contained high mass concentration of suspended particulate matter,grease and heavy metals and other pollutants.Therefore,the use of chemical flocculation treatment technology can effectively remove these pollutants,so that the water quality of the backflow fluid meets the national environmental protection standards.The experimental results showed that the combined treatment method of FECL3 and PFECL3 as flocculant could significantly improve the treatment effect of wastewater.
