Description

本発明は、例えば下水汚泥、動植物性残渣、グリストラップ等のような水分を多量に含んだ有機性廃棄物を処理するのに好適な有機性廃棄物の処理方法に関するものである。   The present invention relates to a method for treating organic waste suitable for treating organic waste containing a large amount of water, such as sewage sludge, animal and vegetable residues, grease traps, and the like.

現在、我々の社会では、例えば下水汚泥、動植物性残渣、グリストラップ等のような水分を多く含んだ有機性廃棄物が様々な場所から大量に排出されている。これらはかなりの悪臭を放つものなので、以前は防水シートで底面を遮水した貯留地に埋設して処理されていたが、防水シートの劣化・破損による地下水汚染等の危険性を考えると十分な処理方法とは言えなかった。   Currently, in our society, organic wastes containing a lot of water such as sewage sludge, animal and vegetable residues, grease traps, etc. are discharged in large quantities from various places. Since these have a rather bad odor, they were previously treated by embedding them in a storage area where the bottom surface was shielded with a waterproof sheet, but considering the dangers of groundwater contamination due to deterioration and damage of the waterproof sheet, it is sufficient. It was not a treatment method.

そこで、現在、これらの有機性廃棄物は、セメントキルンでセメントの原料とともに高熱で焼却したり、焼却炉を用いて高熱で焼却して処理されている。しかし、水分を大量に含んだ有機性廃棄物を高熱で焼却するためには大量の燃料が必要なので、燃料費が嵩み、廃棄物の処理に多大なコストがかかるという問題がある。   Therefore, at present, these organic wastes are incinerated with high temperature using a cement kiln together with raw materials of cement, or incinerated with high heat using an incinerator. However, in order to incinerate organic waste containing a large amount of water with high heat, a large amount of fuel is required, so that there is a problem that the fuel cost increases and the disposal of the waste is very expensive.

また、有機性廃棄物が発生する場所のすぐ近くに廃棄物を高熱で焼却することができるセメントキルンや焼却炉が設置されていない場合は、セメントキルンや焼却炉が設置されている場所まで廃棄物を運ばなければならず、廃棄物の輸送のために費用が更にかかるという問題がある。   If a cement kiln or incinerator that can incinerate waste with high heat is not installed in the immediate vicinity of the place where organic waste is generated, discard it to the place where the cement kiln or incinerator is installed. There is a problem that the goods must be transported and the cost of transporting the waste is higher.

そこで、本件発明者等は堆肥の中にこれらの有機性廃棄物を混合させ、廃棄物中の有機物を堆肥内の微生物に分解させて有機物を減少させ、更に、堆肥内の発酵熱で廃棄物中の水分を蒸発させることによって有機性廃棄物を減容化させる方法を考案した。この方法によれば、廃棄物の処理のために燃料費や輸送費がかからないという利点がある。   Therefore, the present inventors mixed these organic wastes in the compost, decompose the organic matter in the waste into microorganisms in the compost, reduce the organic matter, and further, waste by the fermentation heat in the compost We devised a method to reduce the volume of organic waste by evaporating the water inside. According to this method, there is an advantage that fuel costs and transportation costs are not required for the disposal of waste.

ただ、この方法を採用した場合、堆肥の中の発酵がうまく進まないと、堆肥から大量の悪臭が発生するという問題がある。しかも、堆肥は、多くの場合、周囲が開放された状態の場所に形成されているので、堆肥から発生した大量の悪臭が近隣に拡散し、近隣住民に多大な迷惑を与えるという問題がある。   However, when this method is adopted, there is a problem that a large amount of malodor is generated from the compost if the fermentation in the compost does not proceed well. In addition, since compost is often formed in a place where the surroundings are open, there is a problem in that a large amount of bad odor generated from compost diffuses in the vicinity and causes great inconvenience to neighboring residents.

Figure 2017070906

表４をグラフにしたところ図４に示す通りとなった。表４及び図４に示す通り、堆肥中に廃食油を添加すると発酵が進み、減水率が上昇し出し、堆肥中の廃食油が５〜１０重量％の範囲では発酵が著しくなり、減水率が高くなるが、堆肥中の廃食油が４０重量％を越えると発酵が進まなくなり、減水率が低下することがわかる。   When Table 4 was graphed, it was as shown in FIG. As shown in Table 4 and FIG. 4, when waste edible oil is added to compost, fermentation proceeds, the water reduction rate starts to increase, and in the range of 5 to 10% by weight of waste edible oil in compost, fermentation becomes significant and the water reduction rate is low. Although it becomes high, when waste cooking oil in compost exceeds 40 weight%, it turns out that fermentation stops and water reduction rate falls.

実施例１の試料番号１９の堆肥、すなわち、悪臭の発生がなく、極めて良好に発酵している堆肥を採取し、堆肥中の微生物を、定法を用いて分離・培養し、微生物を同定したところ、Thermus thermophilus、Bacillus subtilis、Bacillus thermoamylovorans、Bacillus licheniformisが見出された。   Composting sample No. 19 of Example 1, ie, compost fertilizing without any foul odor and being excellently fermented, microorganisms in the compost were separated and cultured using a conventional method, and the microorganisms were identified Thermus thermophilus, Bacillus subtilis, Bacillus thermoamylovorans, Bacillus licheniformis were found.

畜糞として鶏糞、豚糞、牛糞＋鶏糞、牛糞＋豚糞、鶏糞＋豚糞、牛糞＋鶏糞＋豚糞を使用し、実施例１と同様の条件で実験をしたところ、臭い、減容化について、実施例１と同様の結果が得られた。   Using chicken feces, pig feces, cow feces + chicken feces, cow feces + pig feces, chicken feces + pig feces, cattle feces + chicken feces + pig feces as animal feces, the experiment was conducted under the same conditions as in Example 1. The same results as in Example 1 were obtained.
