It consists of equipment that performs secondary treatment, advanced treatment, and disinfection processing of oxidizing liquids, and requires a vast area, which poses land acquisition problems.There are also other issues surrounding environmental conservation, making it difficult to acquire land. Because it required dilution water, it was difficult to construct it on remote islands with little water resources. It is also possible to construct a plant on water, but in this case too there would be problems in securing and supplying dilution water.

以上、窒素95%以上である。Next, in the primary treatment step, high-load oxidation treatment and centrifugation treatment are performed. The treatment liquid pumped from the storage tanks 32 and 33 to the front of the circulation pump 42 of the reaction tank 35 is pushed up the circulation pipe 43 by the circulation pump 42 together with the circulation liquid of the reaction 1a35, and sent to the top of the liquid drop pipe 41 where the liquid is The liquid falls from the top of the drop tube 41 in a waterfall shape and enters the liquid in the reaction tank 35. Due to the negative pressure applied to the top at this time, the air suction part 4 provided at the top
4 Inhale a larger amount of air. The inhaled air is finely dispersed in the liquid as it falls, and further dispersed even more finely as it enters the liquid in the reaction tank 35, thereby sufficiently dissolving oxygen into the liquid. By dissolving a large amount of oxygen into the liquid in this way, a large amount of oxygen is secured in the reaction tank 35, which promotes the reproduction of a large amount of aerobic microorganisms, and the human waste remains undiluted and the purification time is short ( It is highly processed in 3 to 4 to 5 days). Further, in the single reaction tank 35, putrefactive substances (BOD, COD, etc.) and nitrogen such as ammonia are removed simultaneously. The removal rate in the reaction tank 35 is BOD 98%

トの用地問題、環境汚染問題を解決することができる。[Effects of the Invention] According to the present invention, since the human waste treatment plant is installed on a barge, the problem of land availability and environmental pollution for the human waste treatment plant can be solved by mooring the barge on the sea.

ことができる。Furthermore, since the human waste treatment plant is mainly based on a primary treatment device equipped with a high-load reaction tank, advanced treatment can be performed without dilution, eliminating the need for dilution water, which is a problem in offshore installations. Furthermore, a primary treatment device equipped with a high-load reaction tank that is heavy and tall is placed approximately at the center of the barge body, and on the left and right sides of it are the reception pretreatment device, secondary treatment device, and subsequent '@@ Because of this arrangement, the stability of the barge body is good, and the flow of work from the receiving pretreatment device to the primary treatment process and the secondary treatment process can be made smooth. Furthermore, since the water discharged from the disinfection device is used for the trimming tank and the healing tank, the discharged water has less salt than seawater and can prevent corrosion of the tank.
