A kind of textile wastewater interception pretreatment equipment

Abstract

The invention discloses a textile waste water interception type pretreatment device, which belongs to the technical field of waste water treatment. The invention can guide and divert the textile waste water through a guiding core column, guide it to a preset annular retention tank at an accelerated rate, and utilize the water flow Impact, the fibers inside can fully contact with the retaining magnetic column, so that the retaining magnetic column can effectively retain the fibers in the wastewater, and at the same time, the multiple magnetic balls set at the water inlet can enter the ring together with the wastewater. At the interception groove, the magnetic attraction force of the intercepting magnetic column to the magnetic ball can be used to make the magnetic ball tightly cover the intercepting magnetic column to cover the trapped fiber, thereby reducing the risk of the fiber falling back into the water under the action of water flow. Possibility, improving the interception effect on fibers, can greatly relieve the filtration pressure of subsequent processing equipment.

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
