Advanced treatment and recycling equipment for printing and dyeing wastewater

Abstract

The invention discloses printing and dyeing wastewater advanced treatment recycling equipment which structurally comprises a base, a treatment machine, an input pipe and a monitoring screen, the top of the base is connected with the left side and the right side of the treatment machine in a welded mode, the bottom face of the input pipe and the top face of the treatment machine are mutually communicated and fixedly connected in an embedded mode, and the monitoring screen is embedded in the front face of the treatment machine. When printing and dyeing wastewater is input, the hydraulic wheel can be driven to rotate through hydraulic power, the angle is adjusted through the twisting frame and the inner supporting frame to obtain the maximum hydraulic impact effect, the wastewater is guided into the water passing pipe during rotation, and the wastewater can be recycled after being filtered and subjected to reaction purification through the reaction column. After being intensively pressurized in the water passing pipe, the nylon fibers are sprayed outwards along with rotation, so that the nylon fibers are guided and sprayed on the filter plate to wash the surface of the filter plate, the nylon fibers accumulated on the surface of the filter plate can be washed to fall off, and the influence on the water inlet effect due to accumulation of the nylon fibers is avoided.

Description

technical field [0001] The invention relates to the technical field of printing and dyeing wastewater treatment, in particular to a device for advanced treatment and reuse of printing and dyeing wastewater. Background technique [0002] Printing and dyeing wastewater refers to the wastewater generated after the printing and dyeing of fiber materials. In the printing and dyeing wastewater, the amount of water is large, the organic pollutants are many, and the alkalinity is strong. Direct discharge to the outside world will cause great damage to the natural environment, so it is necessary to use treatment to return it. After being treated with equipment, it is re-introduced for repeated use. If the printing and dyeing wastewater is produced by printing and dyeing nylon fibers, in addition to various chemicals required for printing and dyeing, the wastewater will also contain a larger content of nylon fibers. During the advanced treatment, it is easy to cause a large amount of ...

[0002] Printing and dyeing wastewater refers to the wastewater generated after printing and dyeing fiber materials. The printing and dyeing wastewater has a large amount of water, many organic pollutants, and strong alkalinity. Direct discharge to the outside world will cause great damage to the natural environment, so it needs to be used for treatment. Use equipment for treatment and return it back for repeated use. If the printing and dyeing wastewater is produced by printing and dyeing nylon fibers, the wastewater will contain a large amount of nylon fibers in addition to various printing and dyeing agents. When performing advanced treatment, it is easy to cause a large number of nylon fibers to be isolated and accumulated after being treated with the isolation net of the equipment. Because nylon fibers have strong corrosion resistance, they will not decompose and degrade after a certain period of time like cotton fibers. Instead, it will accumulate for a long time, which will lead to blockage of the isolation network of the processing and recycling equipment, which will seriously affect the processing speed of the processing and recycling equipment
