Multistage catalytic ozonation device and method

Abstract

The invention discloses a multistage catalytic ozonation device and method. The device comprises a working box, a water inlet is fixedly connected to the middle of the upper end of the working box, a water outlet is fixedly connected to the middle of the lower end of the working box; and a first inner cavity, a second inner cavity, a third inner cavity and a fourth inner cavity are formed in the upper left corner, the upper right corner, the lower left corner and the lower right corner of the working box correspondingly; through a first one-way valve in the first piston and a second one-way valve in the third piston, gas can flow in one direction, so that the oxidation work can be fully performed; through water circulation and gas circulation, the reaction time is shortened, meanwhile, ozone is repeatedly utilized, more cost is saved, and the working efficiency is improved; and through a first cylindrical sliding rail and a second cylindrical sliding rail, a fourth piston and a second piston can conveniently conduct linear sliding work, the phenomenon that the fourth piston and the second piston deviate is avoided, and therefore damage to an upper rack, a lower rack or a third gear is avoided.

Description

technical field [0001] The invention belongs to the technical field of ozone catalytic oxidation devices, and in particular relates to a multi-stage ozone catalytic oxidation device and a method. Background technique [0002] With the increasing shortage of water resources and the frequent outbreak of water pollution incidents, people pay more and more attention to water environmental protection and water pollution control. The state promotes the development of energy conservation and emission reduction by formulating stricter sewage discharge standards. It has become urgent to discharge sewage up to the standard and to carry out recycling on this basis. [0003] Ozone has strong oxidizing ability. In the field of water treatment, ozone is mainly used to oxidize and decompose refractory organic substances in water, thereby decolorizing and deodorizing water body and reducing toxicity. [0004] The existing ozone catalytic oxidation device technology has the following proble...
