Problems solved by technology

But the defect that it exists is that firstly the raw water needs to be pumped to the water inlet tank at the top, and the addition of Fenton reagent needs to be transported from the bottom to the circulating water tank at the top, and then the circulating water pump is sent from the bottom of the oxidation tower to the tower. relatively large energy consumption
Moreover, there is a certain danger in transporting Fenton's reagent to high altitudes
The oxidation tower adopts a rotating water distribution system. During the water distribution process, the friction between the swirling water distributor and the carrier packing in the tower will increase the wear and tear of the equipment, thereby reducing the service life of the equipment.
