Abstract

A method of plasma-purifying sewage includes the following steps: (1) enabling sewage to flow into a sewage box through a water inlet, to flow into an oxidizing box through a filtering screen and then to flow into a plasma purifying box; (2) generating large quantity of high-energy electrons in the plasma purifying box, wherein the high-energy electrons causes destructive impact on the sewage; (3) feeding ozone, which is generated in an electric field, into the oxidizing box through an ozone pump to oxidize the sewage and finally feeding the sewage into the plasma purifying box for continuous circulating treatment. The method is good in sewage treatment effect and is strong in disinfection capability. The low-temperature plasma technology, when being used in water treatment, is high-effective and quick in treatment and is free of any chemical and biological medicines, and is free of generation of any secondary pollution.

Description

technical field [0001] The invention relates to a sewage treatment method, in particular to a method for performing plasma purification on sewage. Background technique [0002] With the increasingly serious pollution and the further development of the deterioration of water environment quality, traditional water treatment methods are more severely challenged. The ever-increasing industrial wastewater is becoming the number one killer of water pollution. With the increase of organic pollutants in water, the number and types of organic halides produced by the chlorination disinfection method that has been used in drinking water have continued to increase, and they have begun to seriously threaten human health. [0003] Plasma sewage treatment device is a new device for domestic sewage treatment and disinfection technology. Through high-energy plasma shocking water body, a large number of strong oxidizing particles, such as hydroxyl radicals, can be generated in the water body...
