Description

Printing and dyeing wastewater circulation treatment device

Technical Field

The utility model belongs to the technical field of printing and dyeing wastewater treatment, more specifically say, in particular to printing and dyeing wastewater cyclic treatment device.

Background

The biochemical treatment of the printing and dyeing wastewater is a common treatment process for industrial wastewater in the printing and dyeing industry, and in the wastewater treatment operation, various pollutants are removed through the biochemical treatment process and are discharged or recycled after reaching the discharge standard.

Industrial wastewater can be generated in the processes of fabric bleaching, dyeing, printing and finishing. The waste water has high chroma, high concentration and more suspended matters. The produced wastewater flows through the grating, and enters a collecting tank of the sewage treatment station to adjust the water quality and the water quantity after large-particle floaters and suspended matters are intercepted. Adding a medicament into the reaction tank, adjusting the pH value, pumping the mixture into a primary sedimentation tank through a lifting pump, coagulating and settling the mixture, and removing the chromaticity, partial organic matters and suspended matters in the wastewater. The effluent enters a hydrolysis acidification pool. In the hydrolysis acidification tank, organic matters in the wastewater are decomposed under the action of microorganisms, long-chain organic matters are degraded into short-chain organic matters, substances which are difficult to degrade are converted into degradable substances, the biodegradability of the wastewater is improved, the effluent of the hydrolysis acidification tank enters an aerobic biological oxidation tank for aeration aerobic treatment, the organic matters in the wastewater are decomposed under the action of aerobic microorganisms, most of the organic matters in the wastewater are removed, and the effluent is filtered to reach the standard and is discharged or disinfected for recycling after suspended matters are removed by a secondary sedimentation tank.
