Self-fading textile wastewater filtering device and using method thereof

Abstract

The invention discloses self-fading textile wastewater filtering device and using method thereof. The invention belongs to the technical field of sewage treatment, the wool fibers can be comprehensively intercepted by the telescopic intercepting columns which are circumferentially distributed on the pre-shunting column; particularly, the intercepting effect of the telescopic intercepting column can be further improved through the inflated and hardened wound airbag rod; on the contrary, the winding characteristic of wool fibers is utilized to improve the fixing effect; after intercepting saturation or ending, the intercepted wool fibers are positioned and prevented from falling off through folding and shrinking of the telescopic interception columns; meanwhile, the passing rate of textile wastewater is improved; finally, the textile wastewater completely passes through; the telescopic interception column is unfolded again and reset; meanwhile, the winding air bag rod is deflated and softened and then is separated from the wound wool fibers, so that the telescopic interception column becomes a smooth cylinder, and the wool fibers automatically fall off from the telescopic interception column to be collected. By means of the device, the wool fiber treatment difficulty of textile wastewater is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, and more specifically relates to a filter device for self-fading textile wastewater and a use method thereof. Background technique [0002] Textile wastewater (Textile effluent) 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 million to 4 million tons every day. Textile industrial wastewater generally contains suspended ...

AI Technical Summary

Problems solved by technology

[0003] Textile wastewater mainly has the following characteristics: (1) the amount of water is large; the pollution of wastewater is mainly organic pollution; (2) the concentration of pollutants is high; the pollutants in wastewater are mainly the second type of harmful substances; (3) most of them are Alkaline, high chroma; (4) The water quality changes greatly, and it is difficult for general wastewater treatment facilities to meet high 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 makes it very difficult for the staff to clean up the wrapped wool fiber, which seriously affects the work efficiency
