本発明は下水や産業廃水を微生物を利用して浄化する水
処理装置の流入負荷分配ル制御装置に関する。[Detailed Description of the Invention] 3. Detailed Description of the Invention [Object of the Invention] (Field of Industrial Application) The present invention is directed to inflow load distribution control for water treatment equipment that purifies sewage and industrial wastewater using microorganisms. Regarding equipment.
(従来の技術)
下水や産業廃水などの有機性廃水は活性汚泥やメタン菌
などの微生物の動きによって浄化される。(Prior Art) Organic wastewater such as sewage and industrial wastewater is purified by the movement of activated sludge and microorganisms such as methane bacteria.
特に近年ではメタン菌を応用した嫌気性処理が省エネル
ギーの観点から注目されている。Particularly in recent years, anaerobic treatment using methane bacteria has attracted attention from the perspective of energy conservation.

り一層の低下を防止する必要が必る。In these water treatment systems, a configuration having a plurality of actuators 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 the plurality of reactors is controlled to be equal. Although this conventional example is very easy to manage, it has the following drawbacks. That is, the purification ability of microorganisms may decrease for some reason, and this cannot be avoided with current technology. If the purification capacity decreases, it is necessary to perform operational management to reduce the inflow load to prevent further decrease in the purification capacity.
しかし、複数のりアクタへ流入廃水ωを均等に分配する
従来例ではこのような対処ができなかった。However, in the conventional example in which the inflowing wastewater ω is evenly distributed to a plurality of glue actors, such measures cannot be taken.
このため、何らかの原因で浄化能力が低下したりアクタ
では、ざらに浄化能力が低下し、処理水質が悪化する。For this reason, if the purification ability is reduced for some reason, or in the case of an actor, the purification ability is drastically reduced, and the quality of the treated water deteriorates.

A flowmeter is provided to measure the flow rate of wastewater flowing into the wastewater inflow pipe and each of the branched inflow pipes, and a thermometer is provided to measure the temperature of the wastewater flowing into the wastewater inflow pipe. A water quality meter is designed to measure the quality of the treated water flowing out from each anaerobic reactor. Also, as a calculation device, the wastewater temperature measured by the thermometer and the wastewater flow rate for each branched inflow pipe are input. Then, by means of determining the base 9% water quality for each anaerobic reactor using a preset standard relational expression, and by using these standard treated water quality and the treated water quality actually measured by the water quality meter, it is determined for each anaerobic reactor. A device having a means for determining the processing capacity and a means for determining the amount of inflow wastewater flowing into the wastewater inflow pipe to be distributed to each anaerobic reactor according to the processing capacity of each of these anaerobic V1 reactors is used.
