Manganese removal and disinfection system for underground water

The utility model provides an underground water manganese removal and disinfection system and relates to a water treatment system. The system comprises a water supply tank, an electrolysis reactor (for placing an electrode plate), a filter column, a backwashing water tank and a pipeline, raw water flows into the electrolytic reactor from the water supply tank and is subjected to electrolytic reaction in the electrolytic reactor, and reaction products are removed through the filter. In the electrolytic reactor, the high-manganese underground water generates strong oxidizing substances under the action of an external electric field, divalent manganese ions in the water are oxidized into tetravalent manganese ions to generate precipitates, and then the precipitates are removed through filtration. Due to the fact that underground water contains rich chloride ions, part of oxygen and a large amount of chlorine can be generated in the electrolysis process, chlorine reacts in water to generate a large amount of hypo
