利点から最近特に注目されている。Conventional technology Figure 7 shows the process flow of a batch type wastewater treatment device.The wastewater that has flowed into the water tank in the inflow process is aerated in the next aeration process, thereby eliminating microorganisms in the wastewater. It provides oxygen to the body and purifies it through the activity of its microorganisms.
Next, it consists of four steps in which microorganisms, ie, sludge, are precipitated and then supernatant water is discharged. Compared to continuous type wastewater treatment equipment, which requires two tanks, a reaction tank and a sedimentation tank, such batch-type wastewater treatment equipment requires only -1 water tank, and by repeating the above steps, it can reach an anaerobic state. It has recently attracted particular attention due to its advantages of being able to create aerobic conditions and denitrification and dephosphorization.

が剥落するという問題があった。Problems to be Solved by the Invention The above-mentioned batch-type wastewater treatment equipment utilizes floating microorganisms in the wastewater, but during the process, the microorganisms that come into contact with the wastewater and absorb oxygen and decompose it grow rapidly. Since the amount of sludge increases, there is a disadvantage that it is necessary to extract excess sludge each time. As a means to prevent such overgrowth of microorganisms, it is known to hold microorganisms in specific positions to suppress their activity. By doing this, a wide variety of microorganisms are propagated by creating a complex mixture of anaerobic and aerobic conditions among microorganisms, and overgrowth is prevented through the food chain, and denitrification etc. It is said that it can be done efficiently. A carrier material is placed in a water tank as a method of retaining microorganisms, but in batch wastewater treatment, the water level fluctuates throughout the process, so when the water level drops, the microbial carrier material rises above the water surface. There was a problem with the microorganisms being exposed and drying, which caused the microorganisms to flake off.

る。And at the beginning of the settling process before discharge, the variable air chamber (17)
By extracting the air inside, the whole body including the microorganism-carrying material (6) sinks to the bottom of the water tank (1), thereby preventing the microorganism-carrying part (13) of the microorganism-carrying material (6) from being exposed above the water. This is what I did. The increase in microbial support material (6) is
This is done after the inflow stroke ends and before the aeration stroke starts. In this case, the extraction of air from the air chamber can be controlled or linked so that the entire chamber gradually lowers as the water level lowers as the supernatant water is discharged. By dividing the air chamber into the fixed air chamber (16) and the variable air chamber (17), the descending speed can be moderated and the overall balance can be adjusted.

Since water is constantly supplied to the microorganisms, the microorganisms can be held in a specific position without drying and peeling off the microorganisms in such a batch wastewater treatment apparatus. Therefore, the problem of sludge treatment due to the proliferation of microorganisms can be solved, and denitrification and dephosphorization efficiency can also be improved.
