Description

Technical Field

[0001] The present invention relates to the technical field of wastewater treatment, and particularly to a device for efficient recycling of printing and dyeing wastewater. Background Art

[0002] With the increasing development of society, environmental protection issues have become increasingly serious. The treatment of organic pollutants, which are the primary source of water pollution, has attracted wide attention. Printing and dyeing wastewater mainly comes from the production processes such as textile dyeing, printing, and finishing, containing a large amount of pollutants such as dyes and chemical auxiliaries. The discharge of printing and dyeing wastewater not only causes serious environmental pollution but also threatens people's health and wastes precious water resources. Therefore, the effective treatment and recycling of printing and dyeing wastewater are of great significance for environmental protection, ensuring people's health, and improving water resource utilization efficiency. The core of this device lies in its ability to recycle wastewater resources. Through specific treatment processes, the device can recover and reuse useful substances in the wastewater, such as dyes and auxiliaries. This can not only reduce resource waste but also lower production costs and improve the economic benefits of enterprises. At the same time, some of the treated water can be reused in the washing and rinsing processes during printing and dyeing production, further reducing the consumption of fresh water resources.

[0003] Chinese Patent Publication No. CN107935244A discloses a device for recycling printing and dyeing wastewater after purification. The present invention relates to a device for recycling wastewater. The technical problem to be solved by the present invention is to provide a device for recycling printing and dyeing wastewater after purification that can effectively improve the coagulation effect, rapidly concentrate and separate pollutants in the dyeing tank, and thus achieve good water quality of the effluent. To solve the above technical problems, the present invention provides such a device for recycling printing and dyeing wastewater after purification, which includes a trolley, a bracket, a first motor, a support rod, a filter box, a first filter screen, a first valve, a water pump, a solution tank, a first water outlet pipe, a first connecting rod, a first slide rail, a compression cylinder, a piston, a disc, a rack, a sector gear, a spray head, a second water inlet hose, a water storage tank, etc. The bracket is sequentially arranged on the trolley from left to right. The present invention achieves the effects of improving the coagulation effect, rapidly concentrating and separating pollutants in the dyeing tank, and thus achieving good water quality of the effluent.

[0004] However, the existing devices have the following problems:

[0005] In the prior art, when staff purify wastewater, due to a large amount of impurities and organic pollutants in printing and dyeing wastewater, these substances are easily adsorbed on the surface or pores of the filter membrane, forming a dense filter cake layer that hinders the flow of water. It is not convenient for staff to disassemble the filter membrane and clean and replace it. Over time, the filter membrane becomes blocked, increasing the operating cost. At the same time, if the stirring is insufficient, the pollutants in the wastewater do not come into good contact with the treatment agent, and the reaction is insufficient, resulting in low pollutant removal efficiency and affecting the overall effect of wastewater treatment. When staff clean the inside of the device, there may be residues remaining on the inner wall of the device, which is not convenient for cleaning. At the same time, it is not convenient to further treat or recycle the treated sewage, thereby reducing the overall practicality of the device. Summary of the Invention

The water outlet pipe 28 at the lower end of the water purification barrel 27 is used to discharge the purified wastewater for recycling.

[0046] In summary, when the printing and dyeing wastewater high-efficiency recycling device is in use:

[0047] 1. First, introduce the printing and dyeing wastewater to be treated into the filter tank 2 through the water inlet pipe 16. The wastewater is preliminarily filtered through multiple filter membranes 29 in the filter tank 2 to remove a large amount of impurities and organic pollutants.

[0048] 2. Secondly, the preliminarily filtered wastewater enters the reaction tank 1 through the connecting pipe 15. After injecting an appropriate amount of treatment agent into the reaction tank 1 through the medicine injection pipe 10, start the motor 11, drive the rotating shaft 12 to rotate, and drive the scraper 13 and the stirring rod 14 to stir the wastewater, so that the agent and the wastewater are fully mixed and reacted. The scraper 13 scrapes the substances attached to the inner wall of the reaction tank 1 to prevent residues from adhering to the inner wall of the reaction tank 1, which may cause inconvenience for the staff to clean the reaction tank 1 and affect the purpose of the next use.

[0049] 3. Then, the treated wastewater is conveyed to the purification barrel 8 through the water pump 19 and the conveying pipe 20. Inside the purification barrel 8, by turning on the germicidal lamp 25, the microorganisms in the wastewater can be killed, and the purified wastewater enters the water purification barrel 27 through the conduit 26 for storage;

[0050] 4. Finally, when needed, open the water outlet pipe 28 to discharge the purified wastewater for recycling. Part of the purified wastewater can be refluxed to the reaction barrel 1 through the reflux pipe 7 and the pressure pump 21 for further treatment or recycling. During the reflux process, the wastewater passes through the filter screen 23 in the treatment box 22 for re - filtration, and the grid frame 3 and the filter membrane 29 are regularly disassembled for cleaning and replacement to maintain the filtering effect, which further facilitates the operation of the staff. At the same time, regularly check the operating status of each component, and repair or replace the damaged components in time.
