塩を中和するだめのアルカリ性物質と。Seaweed 1 mixed with seawater is first crushed 2 and then sent to a sedimentation separator 4. The sedimentation separator 4 contains enough calcium to convert and precipitate sulfate ions in seawater into gypsum, and to neutralize acidic substances that are produced as by-products during gypsum production when the calcium is an acid salt. and an alkaline substance that neutralizes the alkaline calcium salts in unreacted calcium.
更に次のメタン発＃Ｏ際に発生する炭酸ガスを吸収させ

また、沈降分離器４は、海藻と析出した石膏とを分離で

池や、丸目スクリーンを備えたもの等が適用できる。Further, the sedimentation separator 4 can separate seaweed and precipitated gypsum. For example, aeration-type sedimentation ponds used in sewage treatment plants or those equipped with round screens can be used.

られる。O a S 04 * O separated in sedimentation separator 4
a 003 *Slurry 5 containing Mg(OH)2 etc. is collected, and the seaweed is crushed 6 and then sent to a biochemical solubilization tank 7.
ところで、生物化学的可溶化槽７を沈降分離器４の後流
側とする理由は次の通シである。By the way, the reason why the biochemical solubilization tank 7 is placed on the downstream side of the sedimentation separator 4 is as follows.

のために先ず大量のアルカリ性物質を投入し・なければ
ならず、この中和の後に始めて石膏の析出が始まるため
、莫大な薬剤添加が必要となるのである。In the biochemical solubilization tank 7, the seaweed is biochemically solubilized to form a slurry, and at this time polyphonic organic acids are produced. If the operation in the sedimentation separator 4 is performed after the solubilization tank 70, a large amount of alkaline substance must first be added to neutralize the organic acid generated in the solubilization tank 7. However, since gypsum precipitation begins only after this neutralization, a huge amount of chemicals must be added.

れたメタン発酵種菌は、メタン発酵槽８０運転開始時に
投入すればよく、その後Ｏ補悴は不要であることは言う
までもない。The solubilized raw material is sent to the methane fermentation tank 8 and subjected to methane fermentation. As a starter for methane fermentation, for example, obtain a starter from a human waste anaerobic digestion tank, and acclimatize it with seaweed or its main component, alginic acid, and the salt derived from the above-mentioned sedimentation separator operation. The one that has been carried out will be used. Note that acclimatization to this salt content is performed by increasing the concentration one after another. It goes without saying that the methane-fermenting starter bacteria that has been adapted in this manner may be introduced at the time of starting operation of the methane fermenter 80, and that O supplementation is not necessary thereafter.
ここで発生したガスはメタンガス等の有効利用先９へ送
られ、一方、残液、残渣の一部はライン１１から上記の
生物化学的可溶化槽７へ種菌として供給される。The gas generated here is sent to an effective utilization site 9 for methane gas, etc., while a portion of the remaining liquid and residue is supplied from a line 11 to the biochemical solubilization tank 7 as a seed culture.

下での可溶化槽７の操作と安定にする上で運転が軌道に
乗った後でも種菌の供給が必要である。This methane fermentation residual liquid and residue contain a large amount of facultative bacteria in addition to methane bacteria, and when these are sent to the biochemical solubilization tank 7, there is a high concentration of organic acids in the tank 7. Because of this, methane bacteria die in a short period of time, while facultative bacteria continue to proliferate. Note that once the operation of the solubilization tank 7 is on track, there is no need to continuously supply seed bacteria, but there is a large amount of soluble salt that cannot be removed by the sedimentation separator 4 (more than the soluble salt of seawater). Therefore, in order to operate and stabilize the solubilization tank 7 under such high salinity conditions, it is necessary to supply seed bacteria even after the operation is on track.

As this inoculum, methane fermentation residual liquid and residual it can be used.
11) It is important to perform the operation in the biochemical solubilization tank 7 after the operation in the sedimentation separator 4, and if it is the other way around, the drug usage situation will be the same. In addition, the following effects can be achieved.
