Ascidians are mainly incinerated or landfilled. However, in the case of landfill disposal, there are problems that there is a limit to the landfill site and that it emits an extremely unpleasant foul odor.
The amount of treatment is very large and there is a constraint that it must be treated in a short period of time before it decomposes, the incinerator becomes large and both initial cost and running cost increase, and a large amount is periodically discharged. A large-scale storage pit is required when attempting to downsize the furnace by incinerating the object to be processed over time, which requires a large amount of cost for its construction and the construction of the system for transferring the object to be processed. A large amount of cost is also incurred for the control of the bad smell generated from the. In addition, since bone and shell solid matter, stones, sand, and residues are mixed, the life of the incinerator is shortened, and there is a drawback that a large amount of incinerated ash is generated.

発酵が開始される。Next, the process for separating and treating the animal and plant organic solid matter and the inorganic solid matter such as bones, shells and residues will be described. An anaerobic treatment tank 1 containing an animal and plant organic solid substance, such as shellfish, which is an object to be treated, is put in a basket box 2 with the shell attached.
Then, the upper part of the treatment tank is sealed with a lid 5 through a packing, and then an aqueous solution containing at least an anaerobic microorganism group is injected so that the shellfish are completely immersed. This starts anaerobic fermentation.

解消した一次処理液が得られる。The animal and plant organic solid matter is converted to acetic acid or propionic acid through substances having a small molecular weight such as monosaccharides and amino acids by the action of acid-producing bacteria contained in an aqueous solution containing anaerobic microorganisms at an early stage. , Butyric acid, valeric acid, etc. are converted to lower fatty acids and liquefied. Next, in the gas generation process, the organic acids generated in the previous process are decomposed by a group of methane bacteria having a strong substrate specificity, and decomposed into gas such as CH 4 and CO 2 . In this way, the organic matter constituting the animal and plant organic solid matter is converted into organic acid, decomposed into methane gas and carbon dioxide gas, and proliferates as a part of mycelium, but partly dies due to the decrease of the substrate, It is decomposed into methane gas and carbon dioxide gas by other methane bacteria, and as a whole, it progresses in the direction of decrease and mineralization progresses. In this way, the animal and plant organic solid matter is reduced in volume and mineralized, and a primary treatment liquid that solves the problem of unpleasant malodor can be obtained.

る。Although anaerobic fermentation is carried out even if animal and plant organic solids such as shellfish are not necessarily put in the basket box 2, they are put in the basket box from the viewpoint of handling, separation and adjustment of treatment.
At the same time, it is dramatically advantageous to provide a plurality of processing sections so that duplicate processing can be performed. In the anaerobic fermentation, the heating tube 10 is operated to heat the aqueous solution containing the anaerobic microorganisms and animal and plant organic solids such as shellfish to an optimum temperature for gasifying and stirring the mixture. By activating the means 9 to increase the contact between the two, good anaerobic digestion is performed in this treatment tank. Hot water boiler 1
The heat source of 3 may be any of gas, heavy oil, electricity, etc., but it is economical to apply methane gas generated by anaerobic fermentation. The stirring means 9 may be a mechanical stirrer as schematically shown in FIG. 2 in addition to the above gas stirring.
Alternatively, the same result can be obtained by using both methods together.

Since OD is treated only up to several hundreds ppm, its concentration is far higher than the emission control value, and it is necessary to combine a step of decomposing organic matter. This organic matter decomposition method includes a standard activated sludge method, a catalytic oxidation method, a sprinkling filter method, a rotating disk method and the like, and any of them may be used, but in the case of the standard activated sludge method, an aerator tank blower 19 Thus, air is sent from the aeration tank air diffuser 20 into the aerobic treatment tank 18 so that the microorganisms in the aerobic activated sludge absorb oxygen in the air to oxidize and decompose the organic matter. According to this, the final treated water is returned to the anaerobic treatment tank 1 as washing water,
As described above, the water can be effectively used by washing it with inorganic solids such as bones, shells, and debris, or by using it as dilution water for aerobic secondary treatment. The aeration tank liquid is continuously guided to the settling tank 21 to settle and separate the activated sludge. Then, the supernatant water is recycled as washing water or dilution water for the treatment system as described above, or is discharged to the ocean. At the same time, most of the settled activated sludge is returned to the aerobic treatment tank 18 as return sludge, and the rest is stored in the excess sludge tank 22 as excess sludge. When excessive sludge is generated, the sludge is dehydrated by the dehydrator 23 to be solid (cake) and disposed.

いられる。Next, the bypass control valve CV-1 and the supply control valve CV-2 are operated to finalize the primary treated water to be supplied to the aerobic treatment tank, which is the secondary treatment facility, so that the quality and quantity of water are constant. A method of diluting and controlling treated water or fresh water will be described. The aerobic secondary treatment is a anaerobic primary treatment that decomposes residual intermediate decomposition products such as lower fatty acids without decomposition into methane, hydrogen sulfide, ammonia, carbon dioxide, etc. using aerobic microorganisms. However, it is a device for lowering the BOD and COD values to a dischargeable value by making them inorganic. In order to obtain stable treated water quality, a certain BOD load [k
g / m 3 · day] It is desirable to operate the final settling tank with a constant water surface load [m 3 / m 2 · day]. Therefore, the primary treatment liquid is introduced directly into the secondary treatment equipment while being directly introduced into the secondary treatment equipment by diluting the ratio of the primary treatment liquid and the diluting water to a constant concentration and a constant amount of water. As the diluting water, fresh water or treated water subjected to secondary treatment is used.

The concentration of the supply liquid at the inlet of the inlet is constantly measured by a densitometer DC-1, and the opening of the supply control valve CV-2 is adjusted while maintaining a constant flow rate Q of the supply passing through the inlet. The concentration C of is kept constant. To maintain the concentration C, the opening of the supply control valve CV-2 is extremely narrowed at the beginning of the operation when the concentration of the primary treatment liquid is high, and the supply of the concentration C is near when the operation is stopped when the concentration of the primary treatment liquid is low.

Then, a part of the cleaning liquid passes through the bypass, and the other part is sent to the anaerobic treatment tank 1 as cleaning water and dilution water. The cleaning liquid introduced into the anaerobic treatment tank 1 is agitated by the agitating means and a mixed flow of the same amount as the inflow is overflowed and flows out. This effluent joins the dilution water that has passed through the bypass, is diluted, and flows into the aerobic treatment tank. The concentration of the influent at this time was detected by the densitometer DC-1, and the value was set as C.
