ど、蓄量農家にとっては家蓄糞尿の処理は最も頭の痛い
問題であった。Conventionally, household manure, especially from horses, cows, pigs, and chickens, has been used as compost for agricultural crops, but this manure has a high moisture content and is sticky, making it difficult to spread evenly.
Disposal of home-stored manure has been the most difficult problem for farmers, as it emits a foul odor and is a breeding ground for various sanitary pests.

No. 28180), the present invention relates to an improvement of a fermentation treatment method using these fermentation devices. Completely eliminate secondary pollution,
This is a method of processing organic waste that kills two birds with one stone by producing fermented compost at a low cost.The organic waste is fermented through ventilation in the primary fermentation zone, and the fermentation exhaust gas containing ammonia gas from the secondary fermentation zone is separated into exhaust gas and condensed water through a dehumidifier. Then, the exhaust gas containing ammonia gas from the dehumidifier is sent to the secondary fermentation zone, and the condensed water containing ammonia from the dehumidifier is used as regulating moisture in the secondary fermentation zone, and - from the secondary fermentation zone. This is a fermentation treatment method for organic waste in which the ammonia content in the fermentation exhaust gas is deodorized by microorganisms in the secondary fermentation zone, and the fermentation and composting of organic matter is almost completed in the secondary fermentation zone.

２を投入し、空気３を送入して通風発酵させる。To explain the treatment method of the present invention in more detail based on FIG. 1 showing an outline of the process, for example, a Organic waste such as accumulated manure or sewage sludge and, if necessary, a moisture regulating material such as rice husk, straw, and sawdust are mixed to adjust the moisture content to 50 to 70%, and the fermented material 2 is added, and air 3 is supplied. Pour in and ferment with ventilation.

そして２〜５日で一次発酵帯１を通過した一次発酵物は
、二次発酵帯９中に堆積される。The primary fermented material that has passed through the primary fermentation zone 1 in 2 to 5 days is deposited in the secondary fermentation zone 9.

。On the other hand, the fermentation exhaust gas 4 discharged from the secondary fermentation zone 1 is humid air with a temperature of 40 to 50°C and a humidity of 80% or more.
10~200% of the ammonia gas generated in the secondary explosion zone 1
Since it contains about ppm, the fermentation exhaust gas 4 is introduced into a dehumidifier 6 by an exhaust fan 5 and separated into air 8 containing ammonia gas and condensed water 7 containing ammonia.

である。Then, the air 8 containing ammonia gas is introduced into the secondary fermentation zone 9 in which the primary fermentation product has been deposited, and the condensed water 7 containing ammonia is sprinkled to the optimum moisture level. In addition to almost completing the fermentation and composting of organic waste in the secondary fermentation zone 9, the ammonia content in the fermentation exhaust gas 4 discharged from the secondary fermentation zone 1 is absorbed and digested by microbial activity in the secondary fermentation zone 9. This is a fermentation treatment method for organic waste that deodorizes and increases the nitrate nitrogen content in fermented compost.

最適空気通気速度としては３０ｗｎ／ ｍ ｉｎ 〜５
００ｍｍ１ ｍ ｉｎ程度がよい。The optimum air ventilation rate is 30wn/min ~5
Approximately 00 mm 1 min is preferable.

で行なう必要はなく、開放状態で行なってもよい。Note that, as a matter of course, the primary fermentation zone is preferably carried out in a closed container, but the secondary fermentation zone does not necessarily need to be carried out in a closed container, and may be carried out in an open state.

From the point of view of uniform fermentation, stirring the fermented material intermittently
This is even more preferable.
さらに、二次発酵帯よりの排出ガスを回収して一次発酵
帯に循環使用するのはより好ましいものである。Furthermore, it is more preferable to recover the exhaust gas from the secondary fermentation zone and recycle it to the primary fermentation zone.
