Problems solved by technology

[0004] Due to the particularity of textile wastewater, it is easy to cause clogging of the filter material during wastewater treatment, and clogging occurs frequently. In the prior art, once clogging occurs, most of the methods of shutting down and cleaning or backwashing are used to restore the filter layer. Filtration performance will undoubtedly seriously reduce the filtration efficiency of textile wastewater

Embodiment 1

[0042] see Figure 1-2 , a failure self-desorption type textile wastewater treatment device, including a filter tower 1, the upper and lower ends of the filter tower 1 are respectively equipped with a water inlet pipe and a water outlet pipe, and a filter layer 2 is fixedly installed in the filter tower 1, and the filter layer 2 includes a fixed plate 21. A plurality of convex filter ends 22 and concave dirt collection ends 23, the convex filter ends 22 and concave dirt collection ends 23 are alternately arranged on the upper surface of the fixed plate 21, and the convex filter ends 22 and the concave dirt collection ends 23 are kept continuous, The connection between the fixed plate 21 and the convex filter end 22 is inlaid with a magnetic block 4. The lower end of the fixed plate 21 is provided with a plurality of plugging holes matching the convex filter end 22, and the plugging holes are located directly below the convex filter end 22. A matching dredging ball 3 is movably...

Abstract

The invention discloses a failure self-desorption type textile wastewater treatment device, and belongs to the technical field of wastewater treatment. A plurality of dredging balls can be adsorbed below a filter layer, gas can be triggered to generate actions after the dredging balls are in contact with filtered wastewater, and the gas is utilized to push a dredging chain to preliminarily dredge the filter layer; after dredging of the dredging chain is finished, the gas enters wastewater and then forms bubbles, the blocked filter layer is effectively dredged by means of instantaneous impact force generated when the bubbles burst, and the action is continuous, so that water flow at the filter layer is always in a fluctuating state within a long time period, and the blockage condition at the filter layer can be effectively improved; and meanwhile, after the dredging balls lose efficacy, the adsorption effect of the filter layer on the dredging balls can be lost, so that self-desorption to wait for recovery is realized, a new dredging ball is used for replacement and position complementing, and high-efficiency wastewater treatment can be always kept.

Description

technical field [0001] The invention relates to the technical field of waste water treatment, and more specifically relates to an invalid self-desorption textile waste water treatment device. Background technique [0002] Textile wastewater is a variety of wastewater generated in the process of spinning and weaving. Textile industry wastewater can be mainly divided into several categories: printing and dyeing wastewater, chemical fiber textile wastewater, degumming and wool washing wastewater, etc. Among them, printing and dyeing wastewater and chemical fiber textile wastewater are the most polluted. [0003] The textile printing and dyeing industry is one of the industrial sectors that consume a lot of water and discharge a lot of wastewater. According to statistics, the amount of wastewater discharged by printing and dyeing enterprises in my country reaches 3-4 million tons every day. Textile industrial wastewater generally contains suspended solids, grease, lint, surfac...
