Research on Coal Chemical Wastewater Treatment Based on Double Membrane Deep Treatment Technology
In response to the problem of poor sewage treatment efficiency in a coal chemical plant,a dual membrane deep treatment technology combining ultrafiltration and nanofiltration was proposed.Use sand filters,ultrafiltration equipment,and nanofiltration equipment to treat wastewater before discharging it.Experimental analysis shows that the proposed method has a removal rate of 76.87％for ammonia nitrogen and a total hardness removal rate of up to 98.23％in wastewater.The results indicate that the dual membrane deep treatment method constructed by combining ultrafiltration and nanofiltration is feasible in coal chemical wastewater treatment,which can reduce the pollutant content after wastewater treatment and has practical significance in the field of coal chemical wastewater treatment.
