Abstract
The invention discloses a method for purifying aquaculture water by means of non-thermal arc plasma, which comprises the following steps: introducing aquaculture water into a non-thermal arc plasma device; turning on a high-voltage power supply to generate breakdown arcs between one or multiple parallel-connected knife-like stainless steel electrodes and the liquid level of the water; turning on an air source, and enabling the air flow to drive the arcs to slide along the knife-like electrodes through a sprayer so as to form non-thermal arc plasma, thus inducing plasma chemical reaction by means of the plasma; and performing discharge treatment for 5-20 minutes to effectively kill harmful microbe in the aquaculture water, thus achieving the purpose of purifying the aquaculture water. According to the invention, various bacteria in the aquaculture water can be effectively killed by means of the plasma in one step, and organic pollutants in the water can also be decomposed and removed, so that the aquaculture water is purified, and immunity and disease resistance of aquatic products are enhanced; and the device is simple to operate, small in size and convenient to carry, and can be used for periodically sterilizing and disinfecting the aquaculture water.
Description
Technical field
The present invention relates to water technology, particularly relate to a kind of method of Non-thermal arc plasma for purification aquaculture water.
Background technology
The disease that in aquaculture water, harmful pathogenic micro-organism causes easily causes the Large Scale Death of material culture, great financial loss is caused to aquaculture, traditional water body disinfection method has chlorination and disinfection by ultraviolet light etc., chlorination is because of its simplicity and economy, be technology most widely used in liquid disinfection, but chlorine become an outstanding secondary pollution problem gradually on the impact of environment.Also there is fluorescent tube and will regularly replace in disinfection by ultraviolet light, adds investment and operation cost topic.Therefore, low cost, carry out aquaculture water sterilization efficiently, improve water quality, prevent the illness spread in aquaculture system, except the existing technology of improvement, need new technology be developed.
Summary of the invention
For solving the problem, the present invention proposes a kind of method of Non-thermal arc plasma for purification aquaculture water.The method feature is by Non-thermal arc Cement Composite Treated by Plasma aquaculture water, the change of a series of plasma chemistry and reaction can be there is in water in Cement Composite Treated by Plasma, produce hydrogen peroxide, ozone, hydroxyl free radical isoreactivity particle, these active grains have very strong destruction to the microorganism such as bacterium, pathogenic agent, thus reach the effect of sterilizing.
The present invention, for reaching above object, is realized by following technical scheme:
There is provided a kind of method of Non-thermal arc plasma for purification aquaculture water: 1) aquaculture water is introduced Non-thermal arc plasma device; 2) open high-voltage power supply, produce and puncture electric arc, open source of the gas between knife-edge stainless steel electrode and water liquid level, air-flow drives electric arc to slide along knife structure electrode by nozzle, forms Non-thermal arc plasma body, induced by plasma plasma chemical reaction; Harmful microorganism in aquaculture water can effectively kill by discharge process 5 ~ 20min, reaches the object of purifying aquaculture water.
Described Non-thermal arc plasma device, comprises high-voltage power supply (1), knife-edge stainless steel electrode (2), nozzle (5), source of the gas (6) and plastics reactor (7); The knife-edge stainless steel electrode (2) of one or more parallel connections is as an electrode, be connected with one end of high-voltage power supply (1), pending aquaculture water (4), as another electrode, is connected with the other end of high-voltage power supply (1); Gas from source of the gas (6) through pipeline injection nozzle until reactor, gas is oxygen or air; Stainless steel electrode level is placed in pending side waterborne, electrode is dried up surperficial minor increment 3 ~ 8mm; High-voltage power supply power supply voltage range 10000 ~ 20000V.
The principle of purifying aquaculture water of the present invention: Non-thermal arc plasma body is formed and produces a large amount of high-energy electron, in their bombardment water, water molecules generates many active particles:
Wherein active particle OH (hydroxyl free radical), H
2o
2(hydrogen peroxide) and O
3(ozone), HO
2(hydroperoxy radical) etc. are powerful sterilization oxygenants, this oxidizing substance effectively can kill the various bacteriums in aquaculture water, also can decompose the organic pollutant removed in water, aquaculture water is purified, improve immunizing power and the disease resistance of material culture.
The present invention can according to actual requirement purifying aquaculture water, simple to operate, cost is low, portable, avoid storage, transport and keeping, regularly can carry out sterilization and disinfection to aquaculture water.
