Printing and dyeing wastewater advanced treatment system

Abstract

The invention discloses a printing and dyeing wastewater advanced treatment system, and belongs to the technical field of cloth printing and dyeing equipment. Two abutting plates are fixedly mounted on the outer wall of a limiting block, a second magnet capable of repelling a first magnet is fixedly mounted on the lower wall face of the limiting block, the interior of an adsorption tower is filled with adsorbate, and wastewater is led into a filtering tank through a filtering inlet pipe to be subjected to impurity filtering; when the wastewater flows into the filtering tank from the filtering inlet pipe, downward acting force can be generated on a filtering screen in the fixing frame, and the rotating shaft and the rotating groove are connected together in a sleeved mode; when the filtering screen bears the downward acting force, a sliding block slides in a sliding groove, the filtering screen can rotate up and down in the fixing frame, and when the filtering screen rotates in the fixing frame, a spring at the bottom of a screen frame is continuously compressed and rebounded under the pressure of the screen frame so as to increase the vibration frequency of the filtering screen, so that the filtering screen is driven to continuously shake in the fixing frame, and the problem that water cannot flow down due to the fact that meshes in the filter screen are blocked by impurities is solved.

Description

technical field [0001] The invention belongs to the technical field of cloth printing and dyeing equipment, and in particular relates to an advanced treatment system for printing and dyeing wastewater. Background technique [0002] Printing and dyeing is also called dyeing and finishing. It is a processing method, and it is also a general term for pretreatment, dyeing, printing, 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. In order to develop productivity, improving production efficiency is the most direct means; and energy conservation has reached the stage where measures must be taken; while adopting energy conservation measures to develop productivity, environmental awareness and pollution treatment methods must also be developed. A large amount of waste water will be generate...

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
