Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for composting organic waste by mixing organic waste with 11JQI substances, supplying it to a fermenter, and supplying oxygen-containing gas to produce organic waste. Sekicho to decide.

In the above method, conventionally, the output lIl&jI! As a result, foul-smelling gases such as ammonia gas were generated, and there were concerns about environmental hygiene. In addition, during IHQI processing, as the aerobic nature increases, the ofi* in the fermenter increases, and accordingly, the O moisture in the fermenter decreases, and the aerobic activity decreases.
There was a layer between the fermentation process and the efficiency of the fermentation process was significantly reduced.

The present invention addresses the above points, makes it possible to solve the problem of environmental deterioration caused by exhaust gas generated in the fermentation process, and makes effective use of the configuration for this purpose, thereby improving economic efficiency. The purpose is to improve the IJ1 graining rate.

Next, the mode of implementation of this i@Meihodetsu will be explained based on an example.

A large amount of sewage sewage and seed sludge are removed from the second hopper.
l I ill to a mixing device t 1!1;
mixture! 61.

mixture! &Physical substances are supplied to the fermenter (4) and accumulated and retained,
Air is supplied by the blower (I), and the aerobic activity (11j6) is carried out, while exhaust gases such as gases generated during fermentation and excess air are discharged to the outside through the exhaust passage (6). , the fermented material is taken out and fed as -5ta grade sludge to the eighth hopper (phantom) through the return path (7), while the remainder is left as it is or dried if necessary.
After l&at is applied, it is taken out to obtain compost as a product.・The gas discharge path (・) K Exhaust gas spoon jI! In addition to 41, which uses a device (8) to shower the exhaust gas with water or supply the exhaust gas into water for bagging, water is brought into contact with the exhaust gas, and mainly ammonia gas, etc. contained in the exhaust gas is removed. Malodorous substances are captured in 11 liters of water and deodorized.

Exhaust gas spoon! ! The remaining water is collected in a drainage tank (4), and from that tank (-), the collected exhaust gas is passed through the air supply path - a water supply channel υ with a pump ring attached to the middle of the air supply path to the i&bond tank (4). jQ, supply water to the fermenter (4),
While supplying the water pipe into the fermenter (4), C1 inside the tank (4)
It depends.

Exhaust gas station! The water supply pipe (to) the device ($) is the tank (-)
There is also a branch connection to the tank, so that it can be replenished as needed.

A temperature sensor (1st) is installed in the fermenter (4) to detect whether the temperature inside the tank has fallen below the precise range B (for example, 40 to 10'C), and the sensor ① is used to detect the detection result.
If the temperature rises or falls outside the set range, the pump will automatically operate to supply water to the fermentation tank (4), and the aerobic It stabilizes the activity of the surface and improves the firing rate.

In the above embodiment, as the butterfly and juvenile sludge, the sludge treated in the fermentation tank (6) is used. In short, physical substances can also be applied to various kinds of production, such as promoting the fermentation of sewage waste to be composted or controlling temperature, moisture, etc., along with the supply thereof.

In order to supply the oxygen gas to the fermenter (4), high-concentration O fluorine gas, pure oxygen, or the like may be used instead of air.

The present invention is not limited to the composting treatment of sewage sludge as described above, but also includes composting of various organic wastes such as underarm sludge, industrial dead water sludge, agricultural waste, brittle waste, and municipal garbage. Transformation! & Applicable to theory.

In short, the original I! In the organic waste O composting method described in AFi, II, the exhaust gas from the fermenter (4) is brought into contact with water to be deodorized, and the exhaust gas is treated.
It is characterized in that at least -Stm of the subsequent water is supplied to the fermenter (4).

In other words, the foul-smelling gas contained in the exhaust gas can be captured by water and deodorized by contact with the water, thereby solving the problem of environmental deterioration.Furthermore, the exhaust gas can be used to feed the fermenter (4). supply and prevent water shortage in the fermenter 14).
! In addition, it is possible to suppress the decline in aerobic activity and improve the N efficiency, and as a whole, it is possible to save water resources, and the exhaust gas also kills the water after treatment. In that case, it is possible to reduce the amount of OI and water treatment, simplify the transportation facilities, and reduce the number of fish for medicinal value.
We were able to improve I&M efficiency management.
