Abstract
Description
Technical Field
[0001] This utility model relates to the field of anaerobic treatment technology for organic wastewater, specifically to an anaerobic treatment device for organic wastewater. Background Technology
[0002] Anaerobic treatment of organic wastewater is an effective wastewater treatment technology, particularly suitable for treating high-concentration organic wastewater. Anaerobic treatment utilizes the metabolic activities of facultative and obligate anaerobic bacteria to convert organic matter into inorganic matter and a small amount of cellular material without the need for oxygen. These inorganic substances mainly include a large amount of biogas and water. Biogas is a recoverable energy source that can be used for power generation, heating, etc., thus achieving energy recovery. Anaerobic treatment of organic wastewater is a highly efficient, energy-saving, and environmentally friendly wastewater treatment method with broad application prospects. The appropriate type of anaerobic reactor should be selected based on the wastewater characteristics and treatment requirements, and operation management and sludge treatment and utilization should be strengthened.
[0003] The prior art patent document CN204999694U discloses an anaerobic treatment device for high-concentration organic wastewater. In use, compared with the traditional vortex water distribution method, this utility model adopts an internal circulation reflux system, which changes the water distribution method of the influent, improves the uniformity of water distribution, and fully mixes the influent, internal circulation reflux water and granular sludge to form a synchronous upward water flow. This increases the upward flow velocity in the high-load reaction zone, strengthens the stirring effect of the system, greatly increases the organic load of the reactor, and effectively improves the reactor's treatment capacity and resistance to water quality fluctuations.
[0004] However, existing anaerobic treatment devices for organic wastewater generally do not have a scraping function. Suspended solids and organic matter in the wastewater may gradually deposit inside the anaerobic reactor, forming fouling that is difficult to remove. These deposits not only occupy the effective volume of the reactor, but may also affect the flow of wastewater and the metabolic activities of microorganisms. This will shorten the service life of the equipment and increase the frequency and cost of equipment replacement. Therefore, we need anaerobic treatment devices for organic wastewater.

[0022] This utility model provides an anaerobic treatment device for organic wastewater, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the system includes a processing tank 1, with a feed pipe 2 fixedly connected to the top of the tank 1, a water inlet pipe 3 fixedly connected to the outer wall of the tank 1, a drain pipe 5 fixedly connected to the outer wall of the tank 1, and an exhaust pipe 6 fixedly connected to the outer wall of the tank 1.

This allows the second motor 701 to drive the mounting rod 702, which in turn drives the screw 703 to rotate. A threaded sleeve 704 is threadedly connected to the outer wall of the screw 703. The processing tank 1 and the scraper 706 form a sliding structure, with the shape and size of the scraper 706 matching the shape and size of the processing tank 1. Furthermore, the inner wall of the processing tank 1 is fitted against the outer wall of the scraper 706, further enhancing the connection between the processing tank 1 and the scraper 706.

A movable frame 705 is fixedly connected to the outer wall of the threaded sleeve 704, and the scraper 706 is fixedly connected to the outer wall of the movable frame 705. The movable frame 705 forms a threaded structure with the screw 703 through the threaded sleeve 704. The shape and size of the threaded sleeve 704 match the shape and size of the screw 703, and the inner wall of the threaded sleeve 704 fits snugly against the outer wall of the screw 703, strengthening the connection between the movable frame 705 and the threaded sleeve 704.
