An inclined reactor of bottom gas-inlet type for aerobic fermentation and a method for aerobic fermentation are provided, a fermenter is provided with a circular inner tank, end covers and a jacket; an airtight fermentation space is formed in the fermenter by the inner tank, an upper end cover and a lower end cover; a feed opening and an exhaust outlet are arranged at an upper part of the fermenter, and a discharge opening is arranged at a lower part of the lower end cover of the fermenter; a length of the fermenter is greater than or equal to a diameter of the fermenter, the fermenter is fixed on a base having a height difference and is hence in an inclined state; an energy-saving stirrer is mounted in the fermenter, and the energy-saving stirrer is formed by connecting several groups of tangential plates or a spiral combination of tangential plates, a radial rod, a stirring rod and a stirring shaft; several groups of air chambers are arranged at an external wall at the bottom of the inner tank of the fermenter, the air chambers are arranged inside the jacket, several aeration nozzles are defined on an inner side of each air chamber, and the aeration nozzles are close to the inner tank.

A method for preparing a fertilizer using straws and prepared straw organic fertilizer; the method includes: composting straws, spraying a compositing microbial solution containing amino acids to start decomposition of straws, and adjusting humidity of a straw compost, times of spraying a solution of product nutrients, component of the solution to obtain an up-to-standard commercial straw organic fertilizer; and keeping the composting temperature about 70° C. for long time by adjusting the turning time of the straw compost and collocation time of spraying the solution. The method is based on rich organic matters and nutrients in straws, and need for organic fertilization by soil and the like, and by improving the nutrition condition and growing condition of microorganisms of the straw compost, crop straws are directly prepared into high-quality commercial organic fertilizer in short time, so crop straws are completely utilized, and high-quality commercial organic fertilizer product is provided for fertilization.

A portable and modular renewable energy microgeneration apparatus is disclosed that includes at least four modular units. The first modular unit includes a mixing tank and a chopper. The second modular unit includes a buffer tank, a liquor tank, and a pasteurization tank that pasteurizes waste that has been mixed with liquid from the liquor tank by the mixer, chopped into smaller sized components by the chopper, and pre-warmed by the buffer tank. The third modular unit includes a digestion tank that performs anaerobic digestion on pasteurized waste received from the pasteurization tank. And the fourth modular unit includes a gas storage tank that stores gas generated by the waste in at least one of the mixing tank, the chopper, the buffer tank, the liquor tank, the pasteurization tank, and the digestion tank. Each of the four modular units is both portable and modular.
