Abstract

The invention provides a simple plasma water treatment device and method of coal tar wastewater. By means of combination of a physicochemical method and a chemical method, treatment is conducted on the coal tar wastewater, and the method mainly adopts the following processes of flocculation, air flotation and low-temperature plasma oxidation. The water treatment device and the water treatment method belong to the technical field of water treatment. According to the water treatment device and method, by means of flocculation and sedimentation and air flotation, substances, influencing subsequent treatment processes, such as suspended solids and the like in the wastewater are greatly reduced; ultraviolet ray, ozone and the like generated by the low-temperature plasma technology have extremely high oxidability and can effectively decompose organic matter in the wastewater.

Description

technical field [0001] The invention provides a simple plasma water treatment device and water treatment method for coal tar wastewater, belonging to the field of water treatment. technical background [0002] Coal tar is one of the important products of the coking industry, and its composition is extremely complex. In most cases, it is obtained and utilized by the coal tar industry after separation and purification. [0003] A variety of chemical products can be obtained from coal tar finishing, but a large amount of toxic wastewater will be generated during the coal tar processing process. This type of wastewater contains high concentrations of organic substances, high toxicity, and complex components. Among them, organic pollutants are mainly monocyclic or polycyclic aromatic compounds and heterocyclic compounds containing nitrogen, sulfur, and oxygen, such as high concentrations of phenol, naphthalene, aniline, pyridine, quinoline, and benzopyrene. Phenolic compounds ar...
