More Information
Summary:The utility model discloses special equipment for a coal chemical strong brine zero-discharge process. According to the special equipment, methods of two-stage clarifying and softening, ultrafiltration, ion exchange softening, two-stage reverse osmosis, purification and impurity removal and evaporative crystallization to treat the coal chemical strong brine, so that on one hand, the water recovery rate is over 98% and the water resources are saved, and on the other hand, the sludge produced by the system enters a sludge treatment system so as to be dehydrated and environmental pollution caused by strong liquor discharge is reduced, and thus, the coal chemical strong brine zero discharge is realized.
