Textile wastewater purifying and recycling device

Abstract

The invention belongs to the field of textile wastewater recycling, and particularly relates to a textile wastewater purifying and recycling device which comprises an outer cover. The upper surface of the outer cover is fixedly connected with a water inlet pipe, and the upper surface of the outer cover is fixedly connected with a machine body through a connecting pipe. According to the textile wastewater purifying and recycling device, a secondary settling chamber is arranged, after impurities are discharged from a through hole, the accumulated impurities are discharged out of the device from a blow-off pipe, residual liquid water is adsorbed by a multilayer plate and activated carbon, pigments and toxins in the water body are absorbed, large-particle impurities are separated from the water through standing of the standing mechanism, small-particle impurities are separated out while the pH value of the water body is changed through the centrifugal effect and thermal denaturation of organic matter through a centrifugal mechanism, and finally harmful substances in the water body are adsorbed through sedimentation of the secondary sedimentation chamber, so that the purification effect is improved compared with traditional single-stage purification and multi-stage purification, and the problem that a traditional single-stage purification device is poor in purification effect is solved.

Description

technical field [0001] The invention belongs to the field of recycling textile wastewater, in particular to a device for purifying and reusing textile wastewater. Background technique [0002] The textile printing and dyeing industry is one of the industrial sectors that consume a lot of water and discharge a lot of wastewater. According to statistics, the amount of wastewater discharged by printing and dyeing enterprises in my country reaches 3 million to 4 million tons every day. Textile industry wastewater generally contains suspended solids, grease, lint, surfactants and various dyes. For example, cotton textile wastewater often contains cotton scraps and pulp, wool textile wastewater often contains grease; printing and dyeing wastewater often contains pulp, dyes, auxiliaries and various organic substances, etc. [0003] Since there are still recyclable substances in the textile wastewater, if it is discharged directly, it will not only cause waste of resources, but als...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a textile wastewater purification and reuse device, which solves the problem that when the traditional sedimentation tank settles the wastewater, the small particles of impurities and pigment particles cannot be settled, and because the pH value of the water body cannot be changed, the settlement is completed. It is difficult for the water body to meet the discharge and recycling standards
