Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a high-efficiency driving device for a follow-up reverse hanging membrane system. Background Art

[0002] In sewage treatment plants, the odor emitted from sewage pools has a direct or indirect impact on the surrounding environment and the health of operators. During the operation of primary sedimentation tanks, final sedimentation tanks, and sludge concentration tanks, due to the frequent contact and exchange between sewage and air interfaces, a large amount of odor is emitted. The odorous waste gas is very harmful to the human body and has a strong carcinogenic effect after inhalation. At the same time, it will also cause the secretion function of the endocrine system to be disordered and affect the body's metabolic activities; ammonia and aldehydes are irritating to the eyes, causing tears, pain, conjunctivitis, corneal edema, etc. VOC enters the atmosphere and, through photochemical reactions, will also cause PM2.5 and ozone to exceed the standard. Therefore, it is necessary to cover and seal the sewage pool before collecting the odorous waste gas.

[0003] In the sewage treatment process, an efficient driving device of a follow-up inverted membrane system is needed. When most sewage plants in the prior art cover and seal the sedimentation tank, the scraper is sealed in together. In order to meet the inspection needs of the equipment and to use the scraper to repair the surrounding of the pool, when the sewage pool is covered, in order to ensure the normal operation of the scraper, the upper cover of the sewage pool needs to rotate with the scraper. Since the existing inverted membrane cover is very tall and the sealing volume is also large, it not only increases the system gas volume, but also increases the investment in the subsequent odor treatment system, which seriously affects the use quality of the inverted membrane cover and cannot meet the use needs. Therefore, an efficient driving device of a follow-up inverted membrane system is proposed to solve the above-mentioned problems. Utility Model Content
