The application discloses a method for degrading organic pollutants in water by using molybdenum disulfide activated potassium permanganate, which comprises sequentially adding molybdenum disulfide powder and potassium permanganate into water containing trace organic pollutants, treating for 10-90 minutes, and then removing unreacted potassium permanganate and molybdenum disulfide powder through coagulation, sedimentation and filtration in sequence; when the concentration of the trace organic pollutants in the water is 0.1-5 muM, the adding amount of the potassium permanganate is 50-300 mu mol / L, and the adding amount of the molybdenum disulfide is 25-150 mg / L; when the concentration of the trace organic pollutants in the water is greater than 5 muM, the adding amount of the potassium permanganate is 150-500 mol / L, the adding amount of the molybdenum disulfide is 50-200 mg / L, and the adding ratio of the molybdenum disulfide to the potassium permanganate is 1:(0.4-0.8). The method can enhance the degradation capacity of the potassium permanganate by adding the molybdenum disulfide, improve the removal rate of the organic pollutants, reduce the adding amount of the potassium permanganate agent, finally reduce the cost of water treatment, and effectively alleviate the chroma problem caused by a high adding amount of the potassium permanganate.

The invention discloses a method for removing metal pollutants by advanced oxidation enhanced filtration, which comprises the following steps: mixing raw water to be treated containing manganese pollutants with peroxymonosulfate, carrying out ultraviolet radiation, and carrying out oxidation reaction to obtain an oxidized water body; the oxidized water body is filtered through quartz sand, manganese pollutants are removed through reaction, and the purified water body is obtained. By adopting a method of coupling peroxymonosulfate, ultraviolet radiation and quartz sand filtration, the originally mild peroxymonosulfate can be converted into a relatively active oxidation system, the efficient oxidation of the manganese pollutants is realized, the required treatment time is short, and the treatment cost is low. The deep removal of manganese pollutants in low-concentration raw water can be realized under the conditions that a complexing agent is not added, an expensive special adsorbent is not used and a complex filter material is not used.
