Embodiment Construction

[0019] Such as figure 1 As shown, a printing and dyeing wastewater treatment system consists of a regulating tank 1, a lifting pump 2, a coagulation system 3, a primary sedimentation tank 4, a contact oxidation precipitation system 5, a sand filter 6, an activated carbon adsorption tank 7, a sludge pump 8, and a sewage The mud thickening pool consists of 9 nine parts.

[0020] The present invention will be described in further detail in conjunction with the accompanying drawings.

[0021] A printing and dyeing wastewater treatment system consists of the following parts in turn:

[0022] (1) Regulating pool 1: The waste water enters the regulating pool 1, where the water quantity is adjusted and the water quality is balanced. The multilateral water inlet method is adopted to make the wastewater flow out at the same time and not at the same time. The tank is equipped with an air-filled pipe. Due to the full agitation, the homogenization effect of the regulating tank 1 is fully...

Abstract

The invention relates to a printing and dyeing wastewater treatment system, and belongs to the technical field of printing and dyeing wastewater treatment. The system consists of nine parts, namely an adjusting tank 1, a lift pump 2, a coagulating system 3, a primary sedimentation tank 4, a contact oxidation sediment system 5, a sand filtering tank 6, an active carbon adsorbing tank 7, a sludge pump 8 and a sludge concentrating tank 9. The printing and dyeing wastewater treatment system adopts the combined process of coagulation, contact oxidation, sand filtration and active carbon adsorption, and adds the deep treatment processes of the sand filtration and the active carbon adsorption after the physical-chemical treatment coagulation process and the biochemical treatment contact oxidation process. The printing and dyeing wastewater treatment system can be designed and manufactured respectively according to the wastewater quantities of printing and dyeing enterprises, and has the advantages of good treatment effect of printing and dyeing wastewater, stable operation, high degree of automation, simple operation, convenient maintenance, good and stable outlet water quality, superior level to the national emission primary standard and the like. The system particularly has good treatment effect of the printing and dyeing wastewater with high density and high chromaticity.

Description

technical field [0001] The invention belongs to the technical field of printing and dyeing wastewater treatment. Specifically, it relates to an integrated treatment system for printing and dyeing wastewater, which uses pretreatment-physicochemical treatment-biochemical treatment-advanced treatment to treat wastewater, through coagulation, contact oxidation, sand filtration and The combined process of activated carbon adsorption technology can effectively treat printing and dyeing wastewater. Background technique [0002] According to statistics, my country's annual discharge of printing and dyeing wastewater accounts for 35% of the total industrial wastewater discharge. Printing and dyeing wastewater has the characteristics of large water volume, high content of organic pollutants, high content of suspended solids, deep color, high alkalinity, and large changes in water quality. With the rapid development of the dye industry, the variety and quantity of dyes are increasing ...
