In any case, the reality is that it continues to adversely affect the global environment.

泥を遅延なく処理し続ける事である。[Problems to be Solved by the Invention] The organic concentrated sludge of a sewage treatment plant is installed in a concentrating pit (before addition of a coagulant) to feed water, and a traveling type stirring machine and a wood-based bioagent are combined to collect waste. The digestion process should be carried out faster, and the sludge produced every day should be processed without delay.

決まる。The sludge sent to the agitating type bio-agent tank is sprayed on the designated place of the wood-based bio-agent. The sludge that has been sprayed flows down while contacting the wood-based bioagent. At that time, the dirt is adsorbed by the wood-based bioagent. When the water content of the wood-based bioagent is low (4 to 5 hours after spraying), thoroughly stir so that the dirt and the wood-based bioagent are mixed well. The place is left to cure for 3 days thereafter. 4 days later, stir twice in the morning and evening to blow air sufficiently to promote fermentation, decomposition and digestion. By continuing this work for 10 days, the organic concentrated sludge is eliminated. Therefore, since one site is used for 15 days, the size of the equipment is determined by the amount of sludge treated per day.

の水は国で定めた放流基準を充分満足した水である。The permeated sewage that has flowed down to the bottom of the agitation type bio-agent tank is collected in the water collecting tank through the drainage vapor. When the water collecting basin reaches an appropriate amount, the sewage pump automatically operates and is sent to the stirring tank. Aeration is performed with a blower in a stirring tank to prevent sludge from settling and at the same time include air. Sewage that overflows the agitation tank flows into the pump basin. When the amount of the pump box becomes appropriate, the sewage pump automatically operates and is sent to the reaction pipe in the upper center of the wood-based bioagent tank. The sewage flows down while contacting the wood-based bioagent. At that time, the filth is adsorbed by the wood-based bio-agent and is fermented, decomposed and digested. Water seeps out over the entire surface of the wood-based bio-agent tank. The water flows into the inspection basin, and this water is a water that fully satisfies the national discharge standards.

Water comes into contact with activated carbon and filth flows down while being absorbed. The water that has passed through the activated carbon is put into the aeration tank for aeration.

理方法であるが活性炭は吸着作用のみである。[Function] In the past, organic sludge was sprayed on fields and disappeared naturally as fertilizer for crops. This is the action of microorganisms by the soil, and the soil is the microbial growth bed. Similarly, a wood-based bio-agent (Hora agent developed by Sansui Industrial Co., Ltd.) is a microbial growth bed. By stirring and mixing this with sludge, microbial activity is activated and more sludge is treated earlier. It is a thing. Therefore, it is a method of using a stirring machine to activate the activity of microorganisms. Although it is a digestive treatment method by microbial action as a whole, activated carbon only has an adsorptive action.

成３年１１月２２ｍｇ／ｌの検査結果を得ている。[Example] In December 1987, a pig farm in Takasaki City, Gunma Prefecture, did not function as an aeration-type treatment facility, so there was a request to release it. (Mixture) is about 10 m 3 / day of raw water BOD1
It was 4000 mg / l treated water BOD 1200 mg / l and the facility flow was as follows. Moreover, when looking at the state of the raw water, many solid matters such as feces and leftover food were found. As a result of various examinations, it was completed in the middle of May 1988 with the following flow. The treated water BOD at the discharge pump basin treated with this is 30
It was mg / l. However, since the treated water was brown, it was diluted with water and discharged. It has been operating smoothly since then, but it has been 63
Year in late November came out full of sewage from the top of the sudden 50m 3 biological agent primary tank. Upon examination, a black, sand-like substance 1 m deep from the surface of the bioagent clogged the voids of the bioagent and caused a clogging phenomenon. Therefore, it was decided to replace the bio-agent in the 50 m 3 bio-agent primary tank. I dug up with a backhoe and human power, put a black bio agent in the stockyard of feces,
Construction was completed with the addition of new bio-agent. The surface of the bio-agent mixed with sludge in the stockyard returned to its original color after 5 days. After 6 months of stirring with a shovel loader, all bio-agents were restored. Taking this as a hint, we repeated experiments using various organic sludges, and as a result we were convinced that the treatment by this method was optimal.
While it is still used in this pig farm 6m 3 settling basin, 3m 3 Zohana thickener is cleaned once a month, 50m 3 aeration tank, 20m 3 sedimentation pond once a year cleaning also 50m 3 biological agent primary tank It operates by changing the bio-agent once a year. However, the 65 m 3 bio-agent secondary tank has been used without clogging for the past 5 years. It was also released using activated carbon for 15 days to dig a water-diluted well, but it was also found that activated carbon has only an adsorption function. The BOD of the discharge basin is 35 mg / l in July 1991, 12 mg / l in June 1990, and 22 mg / l in November 1991.

In 3), it is sent to the reaction pipe (14) in the upper center of the wood-based bioagent tank (15). It flows out from the reaction pipe (14) to the foundation (16) through the wood-based bioagent (15a). Collect the water and put it in the inspection basin (18). The pumping pump (19) installed on the downstream side of the inspection basin (18) pumps water and sprinkles water on the activated carbon (20a) in the activated carbon cylinder (20). The water discharged from the activated carbon cylinder (20) is put into the aeration tank (21), and the air sent from the blower (11) is aerated by the diffuser pipe (10a) installed at the bottom of the aeration tank (21). The water that comes out of the aeration tank is used for flush toilets or watering the garden. Series of recycling system
