It concerns the method. Conventional technology Wastewater treatment using anaerobic fermentation is a technology that decomposes organic matter in wastewater into methane gas and carbon dioxide gas by the action of anaerobic microorganisms present in the treatment equipment.Activated sludge method As there is no need to aerate with air to supply oxygen, operating costs are low, and the methane gas generated by insects can be used as an energy source. It has been put into practical use in various industrial wastewater treatment equipment. By the way, the anaerobic microorganisms that work as described above have a much slower growth rate than aerobic microorganisms such as activated sludge, so for example, when starting up a newly installed anaerobic treatment device, When starting up the equipment, in order to quickly incubate the wastewater with anaerobic microorganisms suitable for the wastewater to a predetermined amount, it is necessary to obtain sludge for seeding from outside and introduce it into the newly installed equipment. After that, the device is started up.

They were raising their prices.

の大きな要因となっていた。In other words, when starting up an anaerobic treatment device, for example, surplus sludge in the form of slurry with a sludge concentration of 2 to 4% must be input, usually about 174 to 3/4 of the capacity of the device, but the capacity of the anaerobic treatment device is generally several hundred to several thousand one,
Or, in many cases, even larger. Therefore, the volume of surplus sludge that must be transported when starting up an anaerobic treatment facility is extremely large, and special transport means such as tank trucks are required to transport it in slurry form. The transportation costs were extremely high, and this point was a major factor in the increase in costs when setting up an anaerobic treatment facility.

理装置の初期運転方法である。The present invention, which has been made to achieve the above object, is designed to provide an environment in which plants are removed from the outside at the start of operation of an anaerobic treatment unit that processes wastewater containing organic matter by an anaerobic fermentation method. In the method of obtaining sludge for seeding and introducing the sludge into the anaerobic treatment device to start operation, the sludge for seeding is surplus sludge from another anaerobic treatment device already in operation. This is an initial operating method for an anaerobic treatment equipment, characterized in that it uses anaerobic treatment equipment that has been dehydrated.
以下に本発明を詳細に説明する。The present invention will be explained in detail below.
嫌気性処理装置から発生するスラリー状の余剰汚泥は、

処分される。Slurry-like surplus sludge generated from anaerobic treatment equipment is
Usually, it is dehydrated using various types of dehydrators, and then it is disposed of after it is made into a dehydrated nake that is easy to transport and has a reduced volume.

のである。However, conventionally, the anaerobic bacteria such as methane bacteria that make up the excess sludge are said to have extremely low resistance to oxygen, so dehydration treatment is performed and the sludge is capped when exposed to the atmosphere. The dehydrated cake was thought to be unsuitable as sludge for seed planting because the anaerobic bacteria present in the dehydrated cake have died or their activity has significantly decreased. In fact, to this day, there have been no cases of using dehydrated sludge as seed sludge, and as mentioned above, in the past, surplus sludge was placed in a slurry form, for example, in a tank truck and kept in an airtight state. This was used as sludge for planting seeds.

らかとなった。However, according to the research results of the present inventors, among the methane bacteria present in surplus sludge, for example, methanoshrynx (Methanoshrynx), which is present in a relatively large amount in the surplus sludge,
Like methane bacteria belonging to the genus har + othriX),
It has become clear that there are bacteria that are extremely resistant to oxygen and cannot be killed even by aeration and other operations.

Anaerobic microorganisms were able to acclimatize very smoothly, almost the same as when using sludge.

手段を挙げるこεができる。In the present invention, dewatered surplus sludge refers to, for example, human waste, slurry-like surplus sludge generated from anaerobic digestion tanks in sewage treatment plants, and anaerobic treatment equipment used to treat various industrial wastewater. This refers to surplus sludge in the form of slurry generated from sludge that has been dehydrated by some means, and examples of the dehydration means include a centrifugal separator, a vacuum dehydrator, a filter cloth running type dehydrator, or a filter press. Dehydration means can be listed here.

より少ないという点で好ましい。In addition, the most preferable dehydrated sludge is so-called chemical-free dehydrated sludge, in which no chemicals such as flocculants are added during the dewatering process. Rather than those containing inorganic flocculants such as ferric iron, organic flocculants containing so-called polymer flocculants are preferable because they cause fewer problems of killing anaerobic bacteria and decreasing activity. .

気性処理装置内に投入するに際しては、当該汚泥を直接

入するのがよい。When introducing dehydrated sludge into the anaerobic treatment equipment that is about to start operation, it is okay to directly introduce the sludge, but usually water or water to be treated is added to the dehydrated sludge. It is best to reconstitute it into a slurry and then add it.

がなされるからである。The method of the present invention can be applied to all types of anaerobic treatment equipment such as floating type, fixed bed type, fluidized bed type, and upflow sludge blanket type (generally called UASB method), but in particular fixed bed type, Suitable for fluidized bed type and upflow sludge blanket type anaerobic treatment equipment.
The reason for this is that in these devices, the above-mentioned methane bacteria belonging to the genus Methano tlxrix, which are highly addictive to oxygen, become the priority species and decompose the organic matter in the wastewater.

ができる。Effect> As detailed above, according to the method of the present invention, using sludge that has been dehydrated and sterilized, the anaerobic treatment equipment can be started up smoothly in the same way as the conventional method using slurry sludge. Therefore, the amount of seeding sludge that must be obtained from outside at the start of operation can be significantly reduced compared to the conventional method.

減される。In other words, conventionally, the solid content concentration of sludge for seeding was 2 to 4%.
In contrast, in the case of the present invention, dewatered sludge with an extremely high solid content concentration of, for example, 15 to 40% is used, so the volume of sludge to be obtained is smaller than that of the conventional method. The cost for transporting sludge is reduced to about 1/5 to 1/10 of the conventional cost.

めて大である。In addition, the dehydrated sludge can be loaded directly onto a low-cost regular truck, without using expensive means of transportation such as a tank truck, or the sludge can be placed in a simple oven container and the water is drained outside. The cost of transporting sludge can be further reduced because it can be transported using ordinary means of transportation such as E-rasok by loading it onto a truck after it has been brought into a dry state, and therefore the practical value of the present invention is extremely high. It's large.
