Treatment equipment for chemical fiber textile wastewater

Abstract

The invention discloses treatment equipment for chemical fiber textile wastewater, and belongs to the technical field of chemical fiber textile wastewater treatment. By cooperation of a drawing feeding mechanism and a drawing feeding channel, primarily filtered wastewater can be pressed into a pair of arc-shaped filtering channels by large impact force for adsorption and filtration; a plurality ofactivated carbon adsorption particles are used for adsorbing harmful impurities, then the wastewater subjected to secondary treatment is guided into a lower treatment cavity through a filter screen plate to be subjected to coagulation treatment precipitation, and the wastewater is downwards guided out and stamped at a coagulant releaser, so that the leaching of a coagulant is realized, and the coagulation uniformity is improved; furthermore, the attapulgite in the hollowed-out adsorption pipe adsorbs harmful dyes in the wastewater, a plurality of microorganism attachment bodies on the outer side wall of the hollowed-out adsorption pipe realize biological treatment on the wastewater, and the aeration mechanism is matched, so that on one hand, oxygen is supplied to the microorganism attachment bodies, and on the other hand, the bubble amount in the wastewater is effectively increased; therefore, full reaction contact between the coagulant and the wastewater is effectively realized.

Description

technical field [0001] The invention relates to the technical field of chemical fiber textile wastewater treatment, and more specifically relates to a treatment device for chemical fiber textile wastewater. Background technique [0002] Textile wastewater contains a large amount of textile fibers, printing and dyeing additives, slurry produced by beating and desizing, etc., and the impurities contained in it are complex. There are a lot of harmful substances such as cloth threads, fluff and dyeing agents in the wastewater. In order to promote environmental protection, usually After the waste water needs to be treated and then discharged and recycled, a waste water treatment device is required. Pollutants can be divided into two categories according to their sources: one is from the entrainment of fiber raw materials, such as chemical fibers and suspended particles; The difficulty of its processing is greatly increased. [0003] The existing treatment method is to use coagu...

Problems solved by technology

[0003] The existing treatment method is to use coagulation method to treat wastewater. This treatment method is to add coagulant to wastewater, so that fine suspended particles and colloidal particles gather into coarser particles and precipitate, which can be separated from water. A method for purifying sewage, but this method only removes impurities in wastewater by sedimentation and filtration, and it is difficult to remove some fiber fluffs, oils and dyes in water; and the existing coagulation method simply puts them in wastewater Coagulant, the reaction speed is slow and the reaction is not complete, and the treatment effect on textile wastewater needs to be improved
