A kind of advanced treatment system of printing and dyeing wastewater

Abstract

A printing and dyeing wastewater advanced treatment system belongs to the technical field of fabric printing and dyeing equipment; The interior of the filter is filled with adsorbate, and the waste water is passed into the filter tank through the filter inlet pipe to filter impurities. When the waste water flows into the filter tank through the filter inlet pipe, it will exert downward force on the filter screen inside the fixed frame. , the rotating shaft and the rotating groove are sleeved together. When the filter screen is subjected to downward force, the slider slides inside the chute, and the filter screen will rotate up and down inside the fixed frame. When the filter screen rotates inside the fixed frame, The spring at the bottom of the screen frame will be continuously compressed and rebounded by the pressure of the screen frame to increase the frequency of the filter screen vibration, which will drive the filter screen to vibrate continuously inside the fixed frame to prevent impurities from blocking the mesh holes on the filter screen and causing water to fail. shedding problems.

Description

technical field [0001] The invention belongs to the technical field of fabric printing and dyeing equipment, and particularly relates to a printing and dyeing wastewater advanced treatment system. Background technique [0002] Printing and dyeing is also called dyeing and finishing. It is a processing method and a general term for pre-treatment, dyeing, printing, post-finishing, washing, etc. At present, the development trend of the printing and dyeing industry at home and abroad is high efficiency, energy saving and environmental protection. These three aspects complement each other and are indispensable. To develop productive forces, improving production efficiency is the most direct means; and energy conservation has reached the stage where measures must be taken; while taking energy conservation measures to develop productive forces, we must also have environmental awareness and pollution treatment methods. A large amount of waste water will be produced after the cloth ...

AI Technical Summary

Problems solved by technology

A large amount of waste water will be generated after the cloth is produced. In order to reduce environmental pollution, the waste water needs to be treated before being discharged. Usually, the impurities in the waste water are filtered by a filter, and then the filtered waste water is passed into the adsorption tower for decolorization. When using a filter to filter wastewater, the position of the general filter is fixed. When using a filter to filter, impurities will be adsorbed on the fixed filter. After long-term use, the impurities may block the mesh, thus It leads to the problem that the wastewater is difficult to flow down, so a printing and dyeing wastewater advanced treatment system is needed
