| titleOfInvention | Processing method for deeply purifying urban sewage |
| abstract | The invention discloses a processing method for deeply purifying urban sewage. The processing method comprises the following steps: taking urban two-stage biochemical effluent as raw water; putting the raw water into a stirring reactor containing strong alkali and weak acid mixed magnetic microsphere resins and then performing continuous dynamic adsorption; after reacting, putting a mixed solution of the mixed resins and water into a sedimentation basin; after separating the mixed resins from a water body, sending a part of the mixed resins back to the reactor and sending the remained mixed resins into a regenerating pool; sending the mixed resins after being regenerated to a resin storage tank; and meanwhile, continuously pumping the mixed solution of the mixed resins and clean water in a flowing state in proportion into the reactor from the resin storage tank, thereby realizing the dynamic absorption and regeneration of the mixed resins. The processing method can be used for efficiently removing dissolvable organic pollutants from the sewage, especially removing the dissolvable organic matters capable of generating chrominance and removing the indexes such as ammonia nitrogen, hardness, total nitrogen, total phosphorus, and the like. The sewage after being processed can be better applied to industry, landscape, entertainment, and the like. The processing method is simple in process, is low in investment and running cost and is suitable for large-scale sewage treatment. |
