Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings. Such as figure 1 The printing and dyeing wastewater treatment device shown includes a wastewater pool 2, an adsorption clarifier 3, a secondary filter 4, a tertiary filter 5, and a reservoir 6 connected in sequence through a drain pipe 1, and the printing and dyeing wastewater is stored in the wastewater pool 2 Among them, the waste water tank 2 is placed above the adsorption clarifier 3, the secondary filter device 4, the tertiary filter device 5 and the reservoir 6, and the waste water in the waste water tank 2 passes through the adsorption clarifier 3 under the action of the water pressure of its own weight. , After the secondary filtering device 4 and the tertiary filtering device 5 are purified and filtered, the purified water is discharged into the reservoir 6 .

[0015] Further, a stirring device 31 is provided in the adsorption clarification tank 3, and a filter...

Abstract

The invention provides a printing and dyeing wastewater treatment device, comprising a wastewater tank, an adsorption and clarification tank, a secondary filtering device, a ternary filtering device and a reservoir, which are connected in sequence through a water drainage pipe. Printing and dyeing wastewater is stored in the wastewater tank; the wastewater tank is arranged above the adsorption and clarification tank, the secondary filtering device, the ternary filtering device and the reservoir; after the wastewater in the wastewater tank is purified and filtered through the adsorption and clarification tank, the secondary filtering device and the ternary filtering device under the effect of self weight water pressure, purified water is discharged into the reservoir. The printing and dyeing wastewater treatment device provided by the invention combines a physical treatment method and a chemical treatment method and takes the physical treatment method as a main part; the filtering cost is lower and the filtering effect is better; the utilization of a lot of chemical agents in the prior art and secondary pollution caused by the chemical agents are avoided so that green and environment-friendly treatment of the printing and dyeing wastewater is realized.

Description

technical field [0001] The invention relates to the technical field of waste water treatment, in particular to a treatment device for waste water produced in printing and dyeing processing. Background technique [0002] The textile printing and dyeing industry is a large discharge of industrial sewage. Printing and dyeing wastewater is produced in multiple processes such as washing and dyeing, printing, and sizing. It contains a large amount of organic matter such as dyes, starch, cellulose, lignin, detergent, Inorganic substances such as salts are highly polluting, and the discharge of untreated printing and dyeing wastewater will cause serious environmental pollution. [0003] The printing and dyeing wastewater treatment in the prior art mainly adopts the chemical treatment method, but the cost of the chemical treatment method is high, and due to the high content of pollutants in the printing and dyeing wastewater, a large amount of chemical treatment agent is required, wh...
