Description

メタン発酵処理方法では、メタン発酵設備おけるメタン発酵を効率良く行なって処理能力を向上させるべく、有機性廃棄物をメタン発酵設備に供給するのに先立って種々の前処理が行われる。また前処理の一例として、亜臨界水処理が検討されており（例えば、特許文献３、特許文献４参照）、例えば特許文献３には、農業や林業で排出する籾殻、芝生、剪定枝、枯草等のセルロース・リグニン系高Ｃ／Ｎ比低水分廃棄物と屎尿・厨芥系高Ｃ／Ｎ比低水分廃棄物とを一体としてメタン発酵処理するのに先立って、セルロース・リグニン系高Ｃ／Ｎ比低水分廃棄物を、水の臨界点（３７４．１℃、２２．０４ＭＰａ）に近いか又は臨界点以下の条件で水熱処理する亜臨界水処理として、圧力（ゲーシ圧力）２〜２２ＭＰａ、温度２００〜６５０℃、処理時間１分〜１０時間の条件で処理することが記載されている。また特許文献４には、食品の廃棄処理方法として、特にパン及びパン生地等を含む焼き菓子や乳製品等について、１５０〜３００℃、及びその温度に応じた飽和蒸気圧程度の亜臨界水条件下で処理することが記載されている（例えば、特許文献４参照）。
特開２００２−１１９９３７号公報 特開２００４−１３０２０６号公報 特開２００３−９４０２２号公報 特開２００３−２５１３０６号公報 In the methane fermentation treatment method, various pretreatments are performed prior to supplying organic waste to the methane fermentation facility in order to efficiently perform methane fermentation in the methane fermentation facility and improve the treatment capacity. In addition, subcritical water treatment has been studied as an example of pretreatment (see, for example, Patent Document 3 and Patent Document 4). For example, Patent Document 3 includes rice husks, lawn, pruned branches, and hay that are discharged in agriculture and forestry. Cellulose / Lignin High C / N Ratio Low C / N Ratio Waste and Manure / Manure High C / N Ratio Low Moisture Waste Prior to Methane Fermentation Treatment, Cellulose / Lignin High C / N As a subcritical water treatment for hydrothermally treating a specific low moisture waste near or below the critical point of water (374.1 ° C., 22.04 MPa), the pressure (Gaesh pressure) is 2 to 22 MPa, It describes that the treatment is performed under conditions of a temperature of 200 to 650 ° C. and a treatment time of 1 minute to 10 hours. Patent Document 4 discloses, as a food waste disposal method, 150 to 300 ° C. and subcritical water conditions of about a saturated vapor pressure corresponding to the temperature, particularly for baked goods and dairy products including bread and bread dough. (For example, refer to Patent Document 4).
