Description

Technical Field

[0001] This invention belongs to the field of wastewater treatment, specifically an integrated treatment device for textile wastewater. Background Technology

[0002] Textile wastewater is characterized by its complex composition, large volume, high color, and high concentration of organic matter, making it difficult to treat. Pretreatment is necessary first, primarily to remove suspended solids, adjust pH, and lower temperature, creating conditions for subsequent biological treatment. Biological treatment, the core of wastewater treatment, removes organic pollutants mainly through the action of microorganisms. Finally, advanced treatment further processes the wastewater after biological treatment to remove remaining recalcitrant organic matter and pigments.

[0003] Photocatalytic oxidation is an important technology in the deep treatment of textile wastewater. It can effectively remove recalcitrant organic matter and color, improve the stability and reliability of effluent quality, ensure that the effluent quality meets higher standards, and even achieve wastewater reuse.

[0004] Traditional wastewater treatment equipment often involves adding powdered catalysts to the wastewater during the photocatalytic oxidation stage. However, since the catalysts themselves do not participate in the reaction, a micron-level filtration device is required in the discharge stage to filter the catalysts, which affects the drainage and reduces the overall treatment speed. In addition, traditional devices have simple structures, often simply passing the wastewater mixed with the catalyst into a container with a light source, resulting in low overall treatment efficiency.

[0034] All the fitting rings are fixed by the steel cable 16, the outer diameter of the fitting ring 21 is smaller than the inner diameter of the spiral pipe 11, and at the same time, there is a gap between the multiple fitting rings 21, so that the inner diameter of the spiral pipe 11 can be distributed equidistantly, and the water flow passes through the inside and outside of the fitting ring 21, so that the catalyst can be illuminated and washed by the water flow, and the base block 22 is used to increase the surface area of the fitting ring 21 and improve the wastewater treatment effect; when the fitting ring 21 needs to be replaced, the steel cable 16 can be pulled out from the end of the side valve pipe 8, so that all the fitting rings 21 can be pulled out, and the new fitting ring 21 and the new steel cable 16 can be placed into the side valve pipe 8, and then arranged in the spiral pipe 11 under the action of gravity.

[0035] During the wastewater treatment process, the sealing cover 18 seals the side valve pipe 8, the end of the steel cable 16 is blocked by the blocking ring 17, which is convenient for later removal, and the sewage from the outside flows from top to bottom, which can ensure that the multiple fitting rings 21 are completely unfolded and assist the contact between the wastewater and the fitting ring 21.

[0036] In order to facilitate the replacement process of the fitting ring 21, when the steel cable 16 pulls out all the fitting rings 21, the connecting valve 20 at the tail of the steel cable 16 is pulled out from the end of the side valve pipe 8, then the connecting valve 20 is disconnected, the other half of the steel cable 16 and all the fitting rings 21 are separated, the new steel cable 16 carrying the fitting ring 21 is connected to the steel cable 16 through the connecting valve 20, and then the bottom of the steel cable 16 is wound by the electric winding box 9, so that the steel cable 16 and the fitting ring 21 are pulled into the inside of the spiral pipe 11, which facilitates the replacement of the fitting ring 21.

[0037] When the connecting valve 20 is exposed, the rotating nut is separated from the screw rod, and then the steel cable 16 fixed with multiple fitting rings 17 can be separated from the bottom steel cable 16, and the new steel cable 16 can also be fixed by the butt joint of the nut and the screw rod.

[0038] The convex ball 14 is arranged to increase the light reflection angle, so that the reflected light can cover the backlight of the fitting ring 21, and the bottom humidity detector 15 can detect whether there is water in the inside of the reflecting cover 5, so as to judge whether the equipment leaks.

[0039] Different degrees of wastewater need different treatment time, which can be ensured by reducing the water flow speed, and multiple spiral pipes 11 can be connected by the series pipe 10, so that the wastewater can pass through one spiral pipe 11, then enter another spiral pipe 11 through the drain three-way valve 2 and the series pipe 10, and be treated again; multiple spiral pipes 11 can also work independently; using the series pipe 10 can not need to reduce the water flow speed, and does not need additional flow control equipment, which does not require flow control precision, and ensures the quality of the water.

[0040] By opening the maintenance cover 3 and the top cover, the purple light 13 can be taken out, facilitating the maintenance and replacement of the equipment, and the containing frame 4 is used to place the pulled-out steel cable 16 and the matching ring 21, facilitating the disassembly and subsequent reinstallation of the steel cable 16.

[0041] When the containing frame 4 is not used, the connecting rope 6 is first disconnected, then the containing frame 4 is rotated downward from the center, then the end of the containing frame 4 is rotated, the folded containing frame 4 is attached to the protection box 1, then the end of the containing frame 4 is fixed by using the connecting rope 6, the folding and placing are completed, the occupied space can be reduced when the containing frame 4 is not used; at the same time, the connecting rope 6 can be connected to the end of the containing frame 4 when the containing frame 4 is kept horizontal, keeping the horizontal state of the containing frame 4.

[0042] The basic principles, main features and advantages of the present application are shown and described above. It should be understood by those skilled in the art that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the present application. The scope of protection of the present application is defined by the appended claims and their equivalents.
