Abstract
The invention relates to a stone-slab production wastewater treatment process. The stone-slab production wastewater treatment process includes adding to-be-treated stone-slab production wastewater into a coagulation reactor, and feeding magnetic seeds, coagulant aids and coagulants into the coagulation reactor to perform coagulation reaction; guiding mixed liquid obtained after coagulation reaction into a super-magnetic separator to perform super-magnetic separation, directly discharging or reusing water obtained from separation, subjecting micro-magnetic floccules obtained from separation to separation of the magnetic seeds and non-magnetic sludges by a magnetic recovery system, returning the magnetic seeds to the coagulation reactor for coagulation reaction, and enabling the sludges to enter a sludge treatment system for treatment. The stone-slab production wastewater treatment process has the advantages that the stone-slab production wastewater is treated by a super-magnetic separation water purification technology, and the treatment process is further optimized and adjusted, so that the point source and non-point source pollution control requirements of the stone slab industry are met.
