| description | The invention relates to the technical field of manganese industry wastewater treatment devices, and particularly discloses a comprehensive treatment method for electrolytic manganese production wastewater containing middle-high concentration ammonia nitrogen, which comprises the steps of manganese removal, solid-liquid separation of manganese-removed wastewater, precipitation reaction by adding a precipitator and the like. According to the characteristic that the electrolytic manganese production wastewater contains ions such as manganese, ammonia nitrogen, calcium, magnesium, sulfate radicals and the like, more than 95% of manganese ions and all phosphate radicals in water can be selectively removed at the same time by fully utilizing the magnesium ions in the water and pulping by using the quick lime, and excessive calcium ions are not additionally introduced, so that the dosage of magnesium salt and a phosphoric acid agent is effectively reduced, the treatment cost is reduced, and the method is suitable f |
