A method for purifying ship ballast wastewater

Abstract

The invention discloses a method for purifying ship ballast wastewater, comprising the following steps: S1. forming an electric field in a space between a high-voltage electrode and a ground electrode; S2. high-pressure gas in a high-pressure gas cylinder entering the electric field space through a gas flow control valve, A plasma jet is formed and sprayed; S3. The liquid to be treated in the liquid reservoir is sprayed in the form of a spray under the action of a liquid processor after passing through a liquid flow control valve, a filter and a flow meter, and all the spray fields pass through The non-equilibrium plasma jet area; S4. Under the action of the non-equilibrium plasma jet, the target purifying substances contained in the droplet particles in the atomization field are killed; S5. The detection port control valve is opened, and the detection port return pump will The purified liquid is drawn out and sent to the detector; S6. The detector analyzes the purified liquid. A detection mechanism is added to further improve the purification effect.

[0002] In the prior art: 1. Chinese invention patent application number: 201010138133.7, name: high-voltage pulse discharge plasma water treatment device and its high-frequency high-voltage power supply; 2. Chinese invention patent application number: 201010138086.6, name: high-voltage pulse discharge plasma water Treatment device and method; 3. Chinese invention patent application number: 200910022562.5, name: a dual-channel discharge plasma water treatment device; 4. Chinese utility model patent application number: 201120213976.9, name: a high-voltage discharge plasma water treatment device Treatment equipment; these four water treatment devices are characterized by using the sewage to be treated as an electrode or a dielectric plate for atmospheric pressure discharge to directly generate plasma on the surface of the water. The advantage is that the effective contact area between the plasma and water can be increased. The disadvantage is that the conductivity of water is low, which will consume a large proportion of electric energy and reduce energy efficiency
