Problems solved by technology

There are mainly four treatment methods for printing and dyeing wastewater, physical treatment, chemical treatment, biological treatment, and alkali reduction treatment. However, due to the complex composition of printing and dyeing wastewater, a single treatment method often cannot achieve the desired treatment effect. For example, the application number is The patent title disclosed in 201520398981.X is a kind of anaerobic and aerobic integrated device in a printing and dyeing wastewater treatment device. On the one hand, it can save equipment and reduce cost investment. It ca

Embodiment Construction

[0044] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0045] A sewage treatment system for printing and dyeing, such as figure 1 As shown, its overall process includes:

[0046]The impurity removal pool 1 is equipped with a hair removal machine, and the sewage from the printing and dyeing factory is discharged into the impurity removal pool 1, and the first impurity removal is performed by the hair removal machine, and the fine hairs and larger impurities in the sewage are filtered; Collection pool 2, the sewage after preliminary filtration enters the collection pool 2, the sewage in the impurity removal pool 1 flows into the collection pool 2, and the collection pool 2 is set below the ground; The sewage is sent into the adsorption sedimentation tank 3 located at the highest place through the lifting pump, and the activated sludge is added into the adsorption sedimentation tank 3. The activated sludge ...

Abstract

The invention discloses a sewage treatment system for printing and dyeing, which aims to solve the problem that the traditional sewage treatment system has poor decomposition effect on organic matters in sewage. Sewage is sequentially passed into the hair removal tank, collection tank, adsorption sedimentation tank, hydrolysis tank, aerobic tank, degassing tank, sedimentation tank, intermediate tank, dosing tank, air flotation tank, activated carbon tank, secondary sedimentation tank and reclaimed water return Use equipment to physically, chemically and biologically decompose the sewage generated by printing and dyeing. The sewage treatment system for printing and dyeing of the present invention has more thorough and efficient decomposition, thereby completing the systematic treatment of printing and dyeing sewage, effectively solving the problem of sewage discharge, and making contributions to emission reduction and environmental protection.

Description

technical field [0001] The invention relates to the field of sewage treatment, more specifically, it relates to a sewage treatment system for printing and dyeing. Background technique [0002] Printing and dyeing wastewater refers to the wastewater discharged from the pretreatment, dyeing, printing and finishing of cotton, wool, hemp, silk, chemical fiber or blended products. It contains a large amount of complex components such as dyes, sizing agents, and surfactants. It has the characteristics of large chroma, high concentration of organic matter, strong alkalinity, and large changes in water quality and water volume. It is difficult to treat and belongs to difficult-to-treat industrial wastewater. 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, and detergent, as well as inorganic matter such as alkali, sulfide, and variou...
