Textile wastewater interception type pretreatment equipment

Abstract

The invention discloses textile wastewater interception type pretreatment equipment, and belongs to the technical field of wastewater treatment.The interception type pretreatment equipment can guide and distribute the textile wastewater through a guide core column, accelerate and guide the textile wastewater to a preset annular interception groove, and fibers in the annular interception groove can make full contact with an interception magnetic column by means of impact of water flow, therefore, the interception magnetic column can effectively intercept the fibers in the wastewater; meanwhile, a plurality of magnetic wrapping balls are arranged at a water inlet pipe and can enter the annular interception groove along with the wastewater, and the magnetic wrapping balls can be tightly arranged on the interception magnetic column in a sleeving manner to wrap the intercepted fibers by utilizing the magnetic attraction force of the interception magnetic column to the magnetic wrapping balls, therefore, the possibility that the fibers fall back into water again under the action of water flow is reduced, the interception effect on the fibers is improved, and the filtering pressure of follow-up treatment equipment can be greatly relieved.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, and more specifically relates to a textile wastewater interception pretreatment 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. 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, surfactants and various dy...

AI Technical Summary

Problems solved by technology

[0003] Textile wastewater mainly has the following characteristics: First, the amount of water is large; the pollution of wastewater is mainly organic pollution; second, the concentration of pollutants is high; the pollutants in wastewater are mainly the second type of harmful substances; third, most of them are alkaline, Higher chroma; Fourth, the water quality changes greatly, and it is difficult for general wastewater treatment facilities to meet higher discharge standards

[0004] Because textile wastewater is mostly sewage from washing and dyeing of fabrics and threads, the interior contains more wool fiber impurities. Regarding wool fiber, due to its slender characteristics, when treating textile wastewater, the interception treatment of wool fiber It is relatively simple, but because it tends to be linear, after being intercepted, it is more complicated to wrap around the intercepting object, which is likely to cause serious blockage, making it very difficult for the staff to clean up the wrapped wool fiber, which seriously affects the work efficiency
