Description

Technical Field

[0001] The utility model relates to the technical field of oxidation pond related equipment, in particular to an MABR membrane device for oxidation ponds. Background Art

[0002] An oxidation pond is a natural or artificial water body used for treating sewage, mainly degrading organic matter and other pollutants through natural biological processes. Such a system usually utilizes the activities of sunlight, algae, bacteria and other microorganisms to promote the dissolution of oxygen and the transformation of nutrients in the water body, thereby purifying the water quality. By placing the main body of the MABR membrane device in the oxidation pond, the area of the oxidation pond can be reduced, and the purification level and efficiency can be improved in places where it is not suitable to build large oxidation ponds or arrange complex measures for oxidation ponds.

[0003] The main body of the MABR membrane device has extremely high oxygen utilization rate and high microbial oxygen supply capacity in the oxidation pond. After being used for a period of time, the microbial content on the surface of the MABR membrane will gradually become normal, and the outer MABR membrane will gradually age, resulting in a decline in the overall purification effect. However, the main body of the MABR membrane device is not convenient to be taken out of the oxidation pond, and it is impossible to clean the excessive microorganisms on the MABR membrane to reach the normal level, so as to facilitate the subsequent cleaning and maintenance.

[0031] In this embodiment, the lifting mechanism 4 includes a top frame 43 fixedly connected to the top of the mounting frame 2.

[0036] Usage method and working principle of this device:

[0037] First of all, the mounting frame 2 is installed in the oxidation pond body 1. The bearing plate 33 below the mold frame 32 can be inserted into the positioning groove 42 for preliminary positioning. During this process, the inserting rod 53 will be squeezed to compress the spring 56. When the bearing plate 33 completely enters the positioning groove 42, the position of the inserting slot 34 corresponds to that of the inserting rod 53. Under the elastic force of the spring 56, the inserting rod 53 is pushed to reset and inserted into the inserting slot 34, realizing the installation of the MABR membrane device main body 3 on the lifting plate 41, thereby improving the oxygen transfer efficiency and sewage treatment efficiency through the MABR membrane device main body 3;

[0038] After using for a period of time, the microbial content on the MABR membrane purification mechanism 31 will gradually increase, affecting the purification efficiency. By rotating the worm 48, the worm 48 can be manually controlled through a crank or electrically controlled by a motor. When the worm 48 rotates, it can drive the worm wheel 47 to rotate. The worm wheel 47 drives the rotating shaft 44 to wind up the steel cable 46 by the winding wheel 45. At this time, the lifting plate 41 drives the MABR membrane device main body 3 to rise. The air spraying pipe 6 intakes air through the air inlet pipe 62 and blows it to the rising MABR membrane purification mechanism 31 through the nozzle 61. By purging in this way, the excess microorganisms are removed, reducing the microbial content on the surface of the MABR membrane purification mechanism 31 to avoid the decline of the overall purification effect;

[0039] Finally, when the lifting plate 41 drives the MABR membrane device main body 3 to rise to the highest point, the pull ring 57 can be pulled to pull the inserting rod 53 out of the inserting slot 34 through the pull rope 59, and then the mold frame 32 can be removed to further clean and maintain the MABR membrane device main body 3.

[0040] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model in other forms. Any person skilled in the relevant art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
