Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a submersible slow-release oxidant dosing device for treating black and odorous water bodies. Background Technology

[0002] Black and odorous water bodies are a general term for water bodies in urban built-up areas that exhibit unpleasant colors or emit foul odors. They are formed due to pollution loads exceeding the water environment's capacity. Currently, chemical treatment technologies are used to treat black and odorous water bodies. Among these, submerged slow-release oxidant dosing is an important technology in endogenous pollution control and emergency treatment. This involves adding a solid oxidant with slow-release function to the bottom of the water body, usually at the surface of the sediment or the mud-water interface, where in-situ chemical oxidation takes place. Compared to the one-time addition of liquid oxidants, slow-release oxidants can act continuously for a longer period, providing a sustained oxidation environment. There are several ways to add this oxidant, with two main common methods: one is to prepare it in tablet or rod form, and the other is to prepare it in granular form and mix it with a carrier liquid to form a high-concentration solution before adding it through a nozzle. Using a high-concentration solution can provide a larger reaction area and is currently the mainstream dosing method. However, the current submerged slow-release oxidant dosing method has the following drawbacks: When adding the oxidant, the fixed position of the nozzle at the bottom of the tank affects the diffusion of the oxidant and its reaction efficiency with the wastewater. Furthermore, the granular oxidant needs to be mixed with the carrier liquid. Currently, mixing tanks are mainly used for mixing, but the stirring direction is unidirectional, which easily creates dead zones, especially at the bottom and sides of the tank. This causes the powder to float and clump together, affecting the quality of the high-concentration solution.

[0003] Therefore, we propose a submersible slow-release oxidant dosing device for treating black and odorous water bodies to solve the above problems. Summary of the Invention

An inner cavity 720 is opened on the inner side of the traveling trolley 72 at the position corresponding to the traveling rail 721. Multiple traveling wheels 722 are rotatably connected inside the inner cavity 720. Two auxiliary frames 723 are fixedly connected to both ends of the inner cavity 720. Auxiliary wheels 724 are rotatably connected to the auxiliary frames 723. The traveling wheels 722 and auxiliary wheels 724 roll in contact with the traveling rail 721.

[0029] In use, the granular slow-release oxidant and carrier liquid are added to the mixing chamber 22 through the feeding port 214. A high-concentration oxidizing liquid is formed through stirring. This high-concentration oxidizing liquid is sprayed from the injection head 46 in the drug dosing pipeline structure 4. Simultaneously, microbubbles are formed by aeration at the air inlet branch pipe 55. The violent turbulence generated by the rising bubbles instantly mixes the newly added agent with the water and bottom sediment in a three-dimensional manner. Throughout the dosing process, the position adjustment structure 7 drives the mounting frame structure 3 to continuously move and adjust its height and horizontal position to expand the dosing range of the oxidant. This invention uses the mounting frame structure 3 to fix the drug dosing pipeline structure 4 and the aeration pipeline structure 5 together. Combined with the position adjustment structure 7, the mounting frame structure 3 can move horizontally back and forth and continuously adjust its height, thus improving efficiency. The range of dosing is controlled, and the phenomenon of clogging of the injection head 46 by the bottom mud is avoided. The aeration pipeline structure 5 moves accordingly, so that the injection head 46 sprays in the oxidant, and then the aerator 54 releases microbubbles. The violent turbulence generated by the rising bubbles mixes the newly added oxidant with the water and bottom mud in a three-dimensional manner, thereby improving the reaction rate. The lower stirring blade 210 and the upper stirring blade 211 in the chemical mixing structure 2 of this invention use different directions to stir, forming turbulence, reducing the dead zone of stirring, and the upper dispersing blade 212 will disperse the granular oxidant. The bottom scraper 28 and the side scraper 29 continuously scrape the bottom and side wall of the mixing chamber 22 to avoid the wall from being contaminated with oxidant, ensuring the stirring effect, improving the mixing quality, avoiding the phenomenon of powder clumping and floating, and ensuring the quality of the high-concentration oxidant solution.
