VOCs adsorption and desorption integrated equipment and method of treating VOCs-containing wastewater

Abstract

The invention relates to the field of wastewater treatment and in particular relates to VOCs adsorption and desorption integrated equipment and a method of treating VOCs-containing wastewater. The VOCs adsorption and desorption integrated equipment comprises a reaction chamber, a water inlet and a water outlet and further comprises an adsorption device and a desorption device; the adsorption device is mounted on the inner side of the reaction chamber in layers, and the wastewater at the water inlet adsorbed by the adsorption device is discharged to the water outlet in the bottom of the reaction chamber; the desorption device extends from the top of the reaction chamber to the reaction chamber and communicates with the adsorption device on the inner wall of the reaction chamber. The VOCs adsorption and desorption integrated equipment disclosed by the invention can quickly adsorb and desorb VOCs impurities in the wastewater to be separated through the integrated adsorption and desorption devices, so that the space occupied by the machine is reduced, and the adsorption and desorption efficiency of the VOCs adsorption and desorption integrated equipment can be increased.

Description

technical field [0001] The invention relates to the field of wastewater treatment, more specifically, to a VOCs adsorption and desorption integrated device and a method for treating wastewater containing VOCs. Background technique [0002] The production of sewage treatment equipment in developed countries began in the 1960s. Through the treatment of sewage, various impurities in sewage can be effectively removed, so that water resources can be recycled and water resources can be saved. my country is competing in the fierce international market. Stimulated by relying on advanced science and technology and manufacturing industry, the current level of sewage treatment has been gradually improved. [0003] Since the 1990s, the relevant state departments have successively carried out technological transformation on major sewage treatment equipment manufacturing enterprises, which have improved their manufacturing capacity and manufacturing level, and the production level of speci...

Problems solved by technology

[0004] In recent years, wastewater treatment equipment has gradually developed towards miniaturization, and integrated wastewater treatment equipment has also emerged as the times require. At present, integrated wastewater treatment equipment in Europe, America, Japan and other countries and regions has been widely used in urban domestic water Treatment and industrial water treatment, my country has also made great achievements in this area, there have been many integrated treatment equipment, industrial wastewater integrated treatment equipment with the progress of industrial technology, gradually tends to specialization and complete sets, but the domestic The low level of mechanical, electrical and instrumental integration of the equipment limits the development of the equipment in the direction of high technology. In addition, the existing VOCs adsorption and desorption equipment in my country has low adsorption and desorption efficiency, and requires multiple equipment to be used together to operate. It is cumbersome and greatly shortens the service life of the equipment
