Embodiment Construction

[0021] Hereinafter, the present invention will be further described with reference to the accompanying drawings and specific embodiments to facilitate a clearer understanding of the technical ideas claimed by the present invention.

[0022] Such as figure 1 The sludge treatment system produced by the pre-printing and dyeing wastewater treatment of the present invention includes the primary sedimentation tank 1, the anaerobic tank 2, the inclined tube sedimentation tank 3, the sludge thickening tank 4, the plate and frame filter press 5, and the primary sedimentation tank 1. The sludge in the sludge flows into the sludge thickening tank 4 through the sludge pipe. The biogas residue in the anaerobic tank 2 and the sludge in the inclined tube sedimentation tank 3 flow into the sludge thickening tank 4 through the sludge pipe. 4 The sludge pipe is connected to the plate and frame filter press 5, and a sludge pump 41 is installed on the sludge pipe.

[0023] Among them, the body of the ...

Abstract

The invention discloses a system for treating sludge generated by printing and dyeing pretreatment wastewater treatment as well as a treatment process thereof. Sludge precipitated in a primary precipitation pool and an inclined pipe precipitation pool as well as biogas residues generated by an anaerobic tank flow into a sludge concentration pool through a sludge pipe, and the sludge in the sludgeconcentration pool is digested and concentrated, then is conveyed into a plate-and-frame filter press through a sludge pump and is pressed and filtered into a mud cake for outward transportation and treatment; the water content of the sludge can be concentrated from 99 percent to 80 percent or below, so that the volume of the sludge is greatly reduced and outward transportation of the sludge is facilitated; and the characteristics of cleaning the sludge in the primary pool, the inclined pipe precipitation pool and the biogas residues of the anaerobic tank conveniently and performing compression treatment on the sludge through filtering and dehydration to reduce the volume of the sludge and facilitate outward transportation are achieved.

Description

Technical field [0001] The invention belongs to the technical field of textile printing and dyeing pre-treatment wastewater treatment, and specifically relates to a sludge treatment system and a treatment process thereof produced by the treatment of pre-printing and dyeing wastewater treatment. Background technique [0002] Textile finishing can generally be divided into three stages: pretreatment, dyeing, and finishing. According to different weaving methods, cotton and cotton blended textile products can be divided into woven products and knitted products. Except for the slightly different pre-dyeing process, the dyeing and printing process is basically the same. Take woven fabric as an example, the pretreatment process is: grey fabric inspection→singeing→desizing→scouring→bleaching→mercerizing. [0003] The pre-treatment processes that mainly produce wastewater are as follows: [0004] (1) Singeing wastewater. After the singeing of the fabric, it must pass through a cooling cyl...
