| description | The invention provides a desulfurization waste water resourceful treatment system and method. The treatment system comprises a buffer pool 1, a pre-settling tank 2, a first-order reaction flocculating tank 3, a primary clarification concentration tank 4, a second-order reaction flocculation tank 5, a secondary clarification concentration tank 6, a filter 7, a breakpoint chlorination system 8, an intermediate water pool 9, a nanofiltration system 10, a NaCl preconcentration system 11, a Na2SO4 preconcentration system 12, a NaCl evaporation crystallization system 13, a Na2SO4 evaporation crystallization system 14, a dosing system 15, a mother liquor collection tank 16 and a sludge treatment system 17. Compared with the prior art, the method utilizes an ammonia nitrogen removal process to remove ammonia nitrogen in waste water so that long-term and stable operation of an evaporation crystallization device is guaranteed. Through use of membrane separation, concentration and evaporation crystallization processes, |
