| titleOfInvention | A kind of alkali slag wastewater treatment and alkali recovery method |
| abstract | The present invention proposes a method for treating alkali residue wastewater and recovering alkali, comprising the following processing steps in sequence: homogenization; desulfurization and oil removal: pumping the homogeneously treated alkali residue wastewater into an oxidation tower, heating and feeding the alkali residue Air is introduced into the waste water, and oxidation and desulfurization and air flotation are carried out under the agitation of the internal circulation; alkali purification: the sodium carbonate in it is partially converted into sodium hydroxide; three-dimensional electrocatalytic oxidation: the pollutants in it are removed; double-membrane separation : Separation and purification to obtain recycled lye and membrane separation wastewater; biochemical treatment: double-membrane separation wastewater sequentially adjusts the pH value, dilutes, adds nutrient solution, and then enters the MBR membrane pool, and uses the MBR membrane to separate to reduce COD. The invention integrates sweetening, alkali purification, advanced oxidation, membrane separation and purification and biochemical treatment to treat high-concentration and difficult-to-handle alkali residue wastewater, and finally realizes alkali reuse and sewage organic matter up-to-standard treatment, impact resistance Good and low cost. |
