Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment equipment, and specifically relates to a MBBR filler space precision distribution system. Background Art

[0002] When a traditional MBBR reaction tank treats sewage, the filler is placed between two adjacent interception nets in the reaction tank, and the filler and sewage are mixed under the action of the aeration device. During mixing, the bubbles generated by the aeration device continuously float up, causing the filler in the sewage to float on the surface of the sewage along with the bubbles, which will result in the sewage at the bottom of the reaction tank being unable to be fully mixed with the filler, affecting the efficiency of the microorganisms on the filler in treating the sewage, and when cleaning the interception net, the MBBR equipment needs to be stopped before the interception net can be cleaned, which makes the cleaning process of the interception net more cumbersome. At the same time, when the sewage is discharged, the filler is easily gathered at the water outlet of the interception net and the reaction tank under the action of the water flow, causing the filler to block the water outlet of the interception net and the reaction tank, thereby affecting the flow of sewage.
