NOVELTY - Putrefactive organic waste (55-60%) is added with additives e.g. water content regulators like pruning material and an aqueous acetic acid solution containing aerobic and anaerobic bacteria. Moderate humidification and high degree primary fermentation is performed by intermittent ventilation as for bacteria. Secondary and tertiary fermentation is performed, to form mature organic fertilizer.    USE - For manufacturing mature organic fertilizer by composting technique of putrefactive organic waste.    ADVANTAGE - The method enables to manufacture high quality mature organic fertilizer by composting technique of putrefactive organic waste in large quantity at low cost. The putrefactive organic waste is efficiently made as porous substance and decomposition of organic waste is effectively performed. The proliferation of microorganism group is increased by adding pyroligneous acid. The degree of decomposition of decomposition-resistance organic substance is high using high temperature aerobic and anaerobic bacteria, thereby high speed fermentation system is provided. The microorganism group contains selective microbes, thereby fermentation capacity is improved and performed in a short period of time. The organic fertilizer is odorless and secondary environmental pollution is prevented. The deodorizing apparatus is less noise and has longer durability by maintenance.    DETAILED DESCRIPTION - A putrefactive organic waste (55-60%) such as sewage sludge, stock raising waste, or organic waste, human, cattle and pig waste, droppings of hen, return compost or carbonized material, is crush-mixed and added to additives such as water content regulators such as pruning material and an aqueous acetic acid solution. The moisture content is adjusted and a fermentation promoter containing effective aerobic and anaerobic bacteria is added. Moderate humidification and high degree primary fermentation is performed at 70-85 degrees C by intermittent ventilation as for bacteria. The blast weight of the waste is reduced and secondary fermentation is performed at 50-60 degrees C. Then, tertiary fermentation are performed at 50-60 degrees C and 30-40 degrees C, respectively, to form mature organic fertilizer, by intermittent ventilation as for bacteria.    INDEPENDENT CLAIMS are included for:    (1) a mature organic fertilizer; and    (2) apparatus for manufacturing mature organic fertilizer using composting technique of the putrefactive organic waste. The apparatus comprises a blender (3) for mixing and stirring aqueous acetic acid solution such as pyroligneous acid or a bamboo acid liquid, water content regulator and a fermentation promoter containing effective microorganisms with the putrefactive organic waste, a primary fermentation tank (4) equipped with crushing, conveyance and stirring mechanism and a spraying mechanism for humidification. The apparatus further comprises a deodorizer (20) for deodorizing the fermentation gas generated during primary fermentation and microorganism soil, a secondary fermentation tank (7) and a tertiary fermentation tank (8). A sieving machine (11) for classifying mature organic fertilizer after tertiary fermentation with deodorant microorganism, specifically and a pellet granulator (12) for granulating the fertilizer into a pellet, are equipped with the apparatus.
