Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment equipment, in particular to an integrated MBBR sewage treatment device. Background Art

[0002] MBBR technology combines the advantages of both traditional fluidized bed and biological contact oxidation. It is a new and efficient sewage treatment method. It relies on the aeration in the aeration tank and the lifting effect of the water flow to make the carrier in a fluidized state, thereby forming suspended activated sludge and attached biofilm. This allows the moving bed biofilm to use the entire reactor space, giving full play to the advantages of both attached and suspended phase organisms, making them complement each other. Unlike previous fillers, suspended fillers can frequently contact sewage and are therefore called "moving biofilms."

[0003] According to the announcement number CN219823849U, an integrated MBBR sewage treatment device is provided, including a box body, the four corners of the bottom of the box body are fixedly connected with support legs, the box body is sequentially provided with a mixing chamber, an aeration chamber and a sedimentation chamber, and the box body is provided with a sewage treatment mechanism, and the sewage treatment mechanism includes a stirring unit, a water filtering unit and an aeration unit. The integrated MBBR sewage treatment device is provided with a screw connection between the elbow pipe and the drain port, and the elbow pipe and the water injection port are connected by a connector, so that when the filter screen inside the elbow pipe needs to be maintained and cleaned, it can be disassembled by removing the connector and then rotating the elbow pipe, which is convenient for the staff to disassemble and clean, and three groups of water filtering units are provided. When one group needs to be cleaned, closing the one-way valve will not affect the normal drainage and water filtering work of the other two groups, thereby improving the stability of the device during use and making it more convenient to use.

[0004] This patent realizes the disassembly and cleaning of the filter plate inside the connecting pipe, but the filter plate of this patent is arranged inside the connecting pipe and the sewage is transported through a one-way valve, but the sludge in the sewage will adhere to the inside of the one-way valve, causing blockage inside the one-way valve, thereby affecting the fluidity of the sewage. At the same time, when disassembling the filter plate, the connecting pipe needs to be disassembled as a whole, and then the filter plate is taken out. This process is also time-consuming and labor-intensive. In addition, this patent connects the output end of the stirring rod to the bottom end of the mixing chamber. After the device has been used for a period of time, the sealing of the stirring rod cannot be guaranteed, which leads to leakage of sewage in the mixing chamber. The aeration chamber of this patent only contacts the liquid through airflow, so that the liquid is contacted and oxygenated, but the fluidity of the gas in the liquid is low, which leads to a reduction in the oxygenation effect of the liquid. For this purpose, an integrated MBBR sewage treatment device is provided. Utility Model Content
