However, there are various shortcomings listed in the following table: The safety incineration method requires professional skills and personnel operations, and the hazardous chemical system requires professional technical companies and personnel. There is a virus and 5 L378086 10ϊ# December 2nd revised replacement page dangerous high treatment, high risk 'risk rfj Hygiene will cause air pollution will cause air pollution and odor pollution will cause air odor pollution and bandits The volume of pollution reduction volume is reduced by more than 90%, the volume of volume reduction is reduced by more than 30%, and the residue after the final disposal treatment needs to be solidified or composted. The residue after the treatment needs to be composted and reused. Although the time for incineration of disposal time is short, the composting time needs 3 to 6 months. The composting time takes 3 to 6 months. The composting time takes 3 to 6 months. The heat energy can be recycled close to zero organic fertilizer. The space available for sale is smaller and larger (the ratio of 90~180 times the output of each waste). Cost Analysis/Month (for example, 100,000 chicken farms) Cost and ultimate disposal of about NT$300,000 for outsourcing processing of NT$10~150,000 for personnel handling and space use costs of NT$10~150,000 137086 /f-- ' * I---- - I i * Bu. December 2nd revised replacement page I ·* As can be seen from the above table, the organic fertilizers processed by the traditional = method are safe, hygienic, decremental, ultimate Disposal, disposal time, resource reuse, space demand and cost analysis have obvious shortcomings; in addition, incineration is not only expensive in incinerator equipment, high fuel cost, but also operational needs Professionally qualified personnel; in addition, the mining system not only has chemical pollution, but also air pollution, and the above two methods can not produce the re-use of the benefits, the conversion system, the air pollution, stink Flavor pollution The soil pollution is too long; and the time required is too long, and the space required is too large. Therefore, the application for the invention patent is used to improve the treatment and re-marriage of the waste. Processing costs, saving time and work space, and the ultimate product processed is high-grade bio-organic fertilizer' not only can increase profits, but also important agricultural by-products. [Invention content] There are organic fertilizers processed by the above traditional methods, respectively There are obvious shortcomings in terms of safety, hygiene, reduction, ultimate disposal, disposal time, resource re-sharpness, space demand and cost analysis; therefore, the 'inventors are based on the relevant aspects of this aspect for many years. Experience has been developed through long-term research and experimentation, and with the relevant theory, we have finally developed and developed the "method of processing and reuse of the job reading body and its excrement". The main object of the present invention is to provide a method for treating and reusing a dead bird corpse and its excrement, which is to treat and reuse the dead body of a dead bird (such as chicken) and its excrement. Obtained - advanced bio-organic fertilizer, and the method has the following excellent 7 丄 J / δ Ι / δ ϋ, = raw. No professional technology company and simple and non-hazardous operation. m = raw. No air pollution, no odor and no soil pollution. Third, reduction: volume reduction of more than 30%. Fourth, the ultimate disposal: the treated sputum becomes the advanced raw fertilizer.
