Problems solved by technology

Since the cathode rod and the anode rod are respectively placed in two reaction cells separated by an isolation film, the arc discharge effect of the cathode rod and the anode rod is weakened, and the degradation effect on organic pollutants in the aqueous solution is correspondingly weakened, thereby affecting the effect of water treatment. and efficiency; in addition, because the aqueous solution in the reaction tank cannot be continuously degraded, the water treatment efficiency is low

Embodiment Construction

[0019] A device for cyclically degrading organic pollutants in aqueous solution with plasma, comprising a reaction pool 3, a graphite cathode 7 set in the reaction pool 3 as a plasma source, and composed of platinum wire and a quartz tube coated outside the platinum wire anode platinum electrode 5; the top cover 11 of the reaction tank 3 is provided with a water inlet pipe 12, and the lower side of the reaction tank is provided with an outlet pipe 13; the graphite cathode 7 is inserted from the top cover 11 of the reaction tank 3 and is arranged on the reaction tank 3. The curved anode platinum electrode 5 on the lower side faces directly; the above-mentioned water inlet pipe 12, reaction tank 3, and water outlet pipe 13 form a circulation loop through the circulation pump 9. A circulation pool 14 is also arranged between the water outlet pipe 13 and the water inlet pipe 12 of the above-mentioned circulation circuit, so that the aqueous solution through degradation treatment is...

Abstract

An apparatus for cyclically degradating the organic pollutants from aqueous solution by plasma is composed of a circulating cold water pool, reaction pool in said cold water pool and with water inlet and outlet tubes, the cathode and anode rods as plasma source in said reaction pool, and circulating pump.

Description

technical field [0001] The invention relates to a sewage treatment device, in particular to a device for degrading organic pollutants in aqueous solution by using plasma. Background technique [0002] With the rapid development of the chemical industry, a large amount of industrial sewage discharged has caused environmental pollution. Many industrial sewage, especially industrial sewage containing a large amount of organic matter, has high salinity, high acidity, and is difficult to decompose. It cannot be obtained by conventional methods. Good treatment; using advanced oxidation technology to treat organic pollutants in aqueous solution, although the effect is relatively good, but the cost is high and the efficiency is low. Recently, plasma technology has been widely used in sewage treatment because of its strong controllability, high efficiency, and environmental protection. The technical journal "Thin Solid Films" 2001, No.390, pages 154-158 published by ELSEVIER disclos...
