| Abstract | The invention relates to a system and a method for treating coal gasification wastewater by reflux enhanced electric flocculation-chemical precipitation, the system comprises an electric flocculation reaction unit and a chemical precipitation reaction and efficient clarification unit, the coal gasification wastewater sequentially flows through the electric flocculation reaction unit and the chemical precipitation reaction and efficient clarification unit to obtain clarified effluent; wherein the effluent of the electric flocculation reaction unit and the precipitate of the chemical precipitation reaction and efficient clarification unit respectively flow back to the water inlet ends of the respective units. Compared with the prior art, by adopting a double reflux operation mode of electric flocculation effluent reflux and efficient clarification precipitate reflux, not only is the operation stability of the electric flocculation-chemical precipitation process improved, but also the enhanced turbidity removal |
