スに分解される。 This anaerobic treatment method is a method of decomposing organic matter using the action of anaerobic microorganisms. It consists of a two-step gasification reaction that mainly decomposes carbon dioxide into carbon dioxide and methane. Bacteria that cause liquid expansion reactions and bacteria that cause gasification processes are called methane bacteria. In this way, in the anaerobic treatment method, organic matter in wastewater is decomposed into fermentation gas mainly consisting of methane and carbon dioxide gas.

理水質が悪化する。 In such water treatment systems, a configuration having a plurality of reactors is common, especially when purifying a large amount of wastewater such as in sewage treatment. Conventionally, in such water treatment systems, the amount of wastewater flowing into multiple reactors is controlled to be equal. In this conventional example, operation management is very easy, but on the other hand,
It had the following shortcomings: In other words, the purification ability of microorganisms may be reduced for some reason, and this is unavoidable with current technology. When the purification capacity decreases, it is necessary to perform operational management to reduce the inflow load to prevent further decrease in the purification capacity. However, in the conventional example where the amount of inflowing wastewater is evenly distributed to multiple reactors, such measures cannot be taken. Therefore, in a reactor whose purification ability has decreased for some reason, the purification ability is further decreased and the test water quality deteriorates.

An object of the present invention is to provide an inflow load distribution control device for a water treatment device.

にこの快較結果に基づいて流入廃水を分配する。(Function) In the present invention, the amount of wastewater flowing into each anaerobic reactor and the amount of each fermentation gas generated are measured, and the processing capacity of each anaerobic reactor is calculated based on these.
As mentioned above, organic matter in wastewater is decomposed into fermentation gas mainly consisting of methane and carbon dioxide under the action of anaerobic microorganisms. Normally, when 1 kg of COD is decomposed, about 0.3 to 0.5 m 3 of fermentation gas is obtained. Here 0.3
The wide range of ~ 0.5m3 is due to the difference in the composition of COD components. In the case of a water treatment facility consisting of multiple anaerobic reactors, the composition of the wastewater flowing into each anaerobic reactor is naturally the same, so
By comparing the ratio between the amount of wastewater flowing into each anaerobic reactor and the amount of fermentation gas generated, the processing capacity of each anaerobic reactor can be compared. Furthermore, the inflow wastewater is distributed based on this comparison result.
