Problems solved by technology

It is difficult to discharge wastewater up to standard by a single treatment process, and a combination of multiple processes is required
There are still some problems in the reuse of printing and dyeing wastewater, such as: a large amount of wastewater reuse will bring a series of problems to the production and sewage treatment system, mainly including the accumulation of organic pollutants and inorganic salts, making the sewage treatment system unable to operate, and the reuse rate is too high High, without desalination treatment, it will also make production and sewage treatment impossible

Abstract

The invention relates to an advanced dyeing wastewater treatment and reclaimed water reuse system and a method thereof. The system consists of a regulating tank (2), a coagulation tank (3), a preliminary sedimentation tank (4), an acidification hydrolysis tank (5), a deep well (6), a deaeration tank (7), a secondary sedimentation tank (8), a biological activated carbon tank (9), a sludge concentration tank (10), a sludge dewatering tank (11), a filter tank (12) and an ozone oxidation tank (13). The method comprises the following steps: wastewater is sent to the regulating tank, the coagulation tank and the preliminary sedimentation tank, then sludge is returned to the coagulation tank, excess sludge is discharged to the sludge concentration tank, clarified water flows to the acidification hydrolysis tank, is sent to a deep well aeration tank and then sent to the secondary sedimentation tank; and the obtained clarified water is discharged after meeting the standard, or flows to the biological activated carbon tank and is treated for production. The system and the method have the advantages of simple process, low operating cost, high stability and reliability, convenient operation, and realization of automation control. Most of the wastewater discharged is reused in production after the treated wastewater meets the standard, thus reducing emission of pollutants, being capable of eliminating environmental pollution resulting from the wastewater and protecting environment.

Description

technical field [0001] The invention belongs to the field of reclaimed water treatment in textile dyeing and finishing, in particular to a system and method for advanced treatment of printing and dyeing wastewater and reuse of reclaimed water. Background technique [0002] The printing and dyeing industry is an important part of the textile industry. It is not only a key industry to improve product quality and increase product added value, but also an industry that consumes a lot of water, energy, and pollutants. In recent years, driven by the steady and rapid growth of the textile industry, the printing and dyeing industry has developed rapidly, but at the same time it is increasingly constrained by resources and the environment. Printing and dyeing wastewater mainly comes from the two processes of pretreatment and dyeing and printing. It has the characteristics of large water volume, high content of organic pollutants (high COD value), deep color, high alkalinity, and larg...
