Anaerobic baffled reactor suitable for dyeing and finishing wastewater treatment

Abstract

The invention relates to an anaerobic baffled reactor suitable for dyeing and finishing wastewater treatment. The anaerobic baffled reactor comprises a box body (1), middle water baffles (3), baffling chambers (12) and a sedimentation tank (8), wherein a plurality of clapboards (16) are arranged in the box body (1) vertically and uniformly, so that the box body (1) is divided into a plurality of baffling chambers (12); the middle water baffles (3) are arranged in the baffling chambers (12) vertically; baffling boards (4) are connected to lower ends of the middle water baffles (3); filling layers are arranged between the upper ends of the clapboards (16) and the middle water baffles (3); an anaerobic granular sludge layer is paved at the bottom of each baffling chamber (12); a backflow chamber (5) is arranged at the right end of the box body (1); a water inlet pipe (13) is arranged on the left side of the box body (1); and the sedimentation tank (8) which is communicated with the water inlet pipe (13) is connected to the upper end of the right side of the box body (1). The anaerobic baffled reactor has a simple structure, has excellent sludge interception performance and high impact load resistance, and has unique advantage in the treatment of printing and dyeing wastewater with high chromaticity.

Description

technical field [0001] The invention relates to the technical field of printing and dyeing wastewater biological treatment, in particular to an anaerobic baffle reactor for dyeing and finishing wastewater treatment. Background technique [0002] The dyeing and finishing industry is a major player in the industrial discharge industry. The amount of wastewater discharged is large, the content of organic pollutants is high, the color is deep, the pH value varies widely, and the biodegradability is poor. It is one of the difficult industrial wastewater to treat. With the development of new chemical fibers, imitation silk, and printing and dyeing finishing technologies, a large amount of refractory organic substances such as dyes and new additives also enter the wastewater, which adds great difficulty to wastewater treatment and makes the removal of traditional biological treatment systems The efficiency is obviously reduced, the decolorization effect is not good, and it is easy ...

AI Technical Summary

Problems solved by technology

With the development of new chemical fibers, imitation silk, and printing and dyeing finishing technologies, a large amount of refractory organic substances such as dyes and new additives also enter the wastewater, which adds great difficulty to wastewater treatment and makes the removal of traditional biological treatment systems The efficiency is obviously reduced, the decolorization effect is not good, and it is easy to cause fluctuations in the quality of the effluent

At present, there is no high-efficiency, convenient operation and management of biological treatment equipment applied to the field of printing and dyeing sewage treatment
