Problems solved by technology

[0003] However, when the existing xylene sewage is treated, xylene is usually filtered multiple times to meet the later discharge standards. However, although this filtering method removes a certain amount of xylene in the wastewater, it is not effective in removing the xylene in the wastewater. When xylene is used, it is easy for xylene to come into contact with other solvents, thereby reproducing other pollutants, causing further diffusion of xylene

Abstract

The invention discloses a sewage treatment system in a xylene processing process, and belongs to the technical field of sewage treatment.The sewage treatment system comprises a filter assembly, a plate type filter cartridge and a rectifying tower. The filter assembly further comprises a honeycomb filter plate and a peat plate, and the honeycomb filter plate and the peat plate are supported and connected through a supporting column; and an abutting bearing cover is installed at the bottom of the filtering assembly, a connecting cylinder is fixedly connected to the bottom of the abutting bearing cover, and one side of the connecting cylinder communicates with a connecting pipe. According to the device disclosed by the invention, by virtue of the honeycomb filter plate and the peat plate which are matched with the filtering assembly, xylene in wastewater can be further condensed under the heating action of the heating assembly, so that the xylene is adsorbed and filtered by the peat plate and filter columns in honeycomb filter holes; and meanwhile, the arranged filling layer adopts ceramic ball adsorption, so that the wastewater can be further treated when passing through the activated carbon adsorption plate.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment system during xylene processing. Background technique [0002] Xylene is an organic compound. In industry, xylene refers to the mixture of benzene isomers. Xylene has certain toxicity. It is easy to cause poisoning to the body when inhaling or eating xylene. At the same time, xylene is harmful to the eyes and The respiratory tract has a strong stimulating effect, and it also has a certain anesthetic effect at high concentrations, so xylene is a dangerous gas. During the production and processing of xylene, a certain amount of xylene will be discharged into the natural environment with the waste water during production and processing under pressure and external factors. If the xylene contained in these waste water is not passed through Any treatment, direct discharge can cause pollution to the environment. [0003] However, in the existing xylene sewa...
