In the inoculum tank 300, fresh water (65-70%) and raw water (sewage) at a rate of 30-35% are put, and microorganisms such as photosynthetic bacteria, lactic acid bacteria, yeast, actinomycetes, etc. are put therein, and the microorganisms are combined. Incubate. By adding a large amount of fresh water, the microorganisms that have been cultured in a complex manner are activated as if they were hungry because the amount of raw water, which is wastewater, is small.

The microorganisms prepared here become insufficient even if microorganisms have already been introduced, and when the activity is lost due to being full, the first to fourth sewage treatment tanks 211 to 2 are used.
14 as appropriate. Thus, the running cost can be reduced by improving the action of the microorganisms.

The raw poultry manure that has fallen into the waterway 118 in the building 110 is submerged in the water, and then is scraped by a scraper or the like, and the sewage mixed with the poultry manure is sent to the first sewage treatment tank 211 by a sewage pump or piping (not shown). Send in.

In the first sewage treatment tank 211, a stirrer 217
The chicken manure is dissolved, and undigested calcium and corn and other cereal grains precipitate, forming a floating mass, such as organic matter that has not undergone fermentation and decomposition, a so-called scum, forming an upper layer, and homogenizing in the middle layer. To form a cloudy sewage layer. When the scum of the upper layer floats and passes through the blades 216 of the agitator 217, it is finely crushed here. In addition, feather 2
16 sends air (oxygen) into the water by tapping the water. As a result, the organic matter constituting the chicken dung is subjected to fermentation and decomposition by microorganisms, and is decomposed into hydrogen, carbon dioxide, water and the like.
Nitrogen, phosphorus, potassium, calcium and the like also float or precipitate alone or in the form of a compound.

The intermediate sewage is sent to the second sewage treatment tank 212 by the pipe 215, where the first sewage treatment layer 211
Is performed, and fermentation and decomposition by microorganisms proceed.

Further, the intermediate wastewater is removed by a third pipe 215.
The water is sent to the sewage treatment layer 213, and the same processing is performed to further purify the sewage.

Further, intermediate wastewater is removed by a pipe 215 to a fourth place.
The wastewater is sent to the sewage treatment tank 214, where the same treatment is performed, and the sewage is purified. When purification is insufficient, the water is returned to the first to third sewage treatment tanks 211 to 213 by a pump 219 via a pipe 218 as appropriate.

Although it may not be necessary in a warm place, in a cold region, the body temperature of the chicken, air heated by the poultry raising lamp 120 or other heating means in the building 110 of the poultry house 100 is blown off by a blower (not shown). 1st to 4th sewage treatment tanks 211 to 21
4 to supply air (oxygen) and raise the temperature of the sewage in each of the tanks 211 to 214 to activate the activity of microorganisms and promote fermentation and decomposition. A large amount of microorganisms can be processed in a small amount, and the running cost can be reduced.

The precipitate gradually decreases from the first sewage treatment tank 211 to the fourth sewage treatment tank 214, but the precipitate is periodically removed. Degradation of the sediment proceeds further if the sediment is left for a long period of time. However, depending on the contents of the field, etc., the sediment in an appropriate tank is mixed with the soil of the field to become fertilizer.

In the field where the fertilizer is sown, the microorganisms are mixed, the decomposition is promoted, there is no odor, the growth of the crop is good due to the action of photosynthetic bacteria, etc., and the propagation of spoilage bacteria is suppressed. I do.

By selectively withdrawing the intermediate sewage in each tank and dispersing it in the field, it becomes liquid fertilizer like the sediment, and the same effect can be obtained.

The purified water in the fourth sewage treatment tank 214 whose temperature has risen due to the fermentation decomposition is supplied to the valve 2 of the pipe 221 by the pump 222.
The water is supplied from 23 to a water channel 118, and further heated in the building 110 of the poultry house 100 and sent to the first sewage treatment tank 211 so that the sewage in the tank does not become low in temperature. By warming the sewage in this manner, the ability of microorganisms to work can be enhanced, thereby speeding up the treatment with fewer microorganisms and suppressing running costs.

Further, since sewage (purified water) containing microorganisms is supplied to the water channel 118 from the sewage treatment tank 200 and circulated, there is no generation of mold and the like in the poultry house, and furthermore, the invasion of other bacteria is suppressed. Also, the environment is good for chickens and it is hard to get sick. In addition, by adding this purified water to the drinking water of chickens or feeding it into feed, it is possible to prevent chicken diseases.

[0035]

According to the first and second aspects of the present invention, chicken dung can be treated without generating bad odor and without deteriorating environmental hygiene, and the precipitates and liquids obtained by the treatment can be nitrogen and phosphorus. , Potassium, calcium, can be used as fertilizer. In the case of liquid fertilizer, unlike powder, the concentration can be adjusted appropriately, and it is sucked into the soil of the field, and there is no need to wait for rain or spray water. In any case, when the land is returned as fertilizer, the microorganisms contained therein prevent the growth of other bacteria such as mold and improve the growth of crops, for example. It is especially effective for poultry raising in cold regions. Furthermore, fermentation decomposition can be promoted.

According to the invention of claim 3, since the purification Kamizu the circulating water waterways, no occurrence of mold in the poultry house, and
In addition, it controls the invasion of other bacteria, making the environment good for chickens.
It is hard to get sick.

According to the fourth aspect of the present invention, heat and air (oxygen) are supplied by blowing warm air in the poultry house into the sewage treatment tank to improve fermentation decomposition.

According to the fifth aspect of the present invention, since microorganisms cannot sufficiently act on scum floating in water, the scum is crushed in water and oxygen is supplied to improve the fermentation and decomposition by microorganisms.
