In order to optimize the reuse treatment technology of high salt wastewater in coal chemical production,a single factor variable control method was adopted,and the water flux of the tubular ultrafiltration device in wastewater reuse treatment was taken as the variable.Four operating conditions of 100,120,140,and 160 L/(m2·h)were designed to compare the salt concentration,turbidity,solubility fixation,conductivity,potassium dichromate index,total hardness,oil,suspended solids,pH value,and wastewater pollutant removal rate of the treated water samples under different water fluxes.Result:The highest pollutant removal rate was achieved when the water flux was 120 L/(m2·h),and all indicators met the standards for high salt wastewater reuse.Conclusion:The water flux parameter of the tubular ultrafiltration device in the high salt wastewater reuse treatment technology is optimized to 120 L/(m2·h)to ensure the quality of wastewater reuse treatment.
