Fermentation device and method for rapid decomposition of vegetable waste

Abstract

The invention discloses a fermentation device for rapidly composting vegetable wastes and a using method and effect of the fermentation device. The device is attractive in appearance and practical, is a hollow cylinder and comprises the following eight systems: a fermentation system, a sterilization system, a monitoring system, a ventilation system, a filtrate collection system, a heat insulation system, a deodorization system and a tool system; the device can be used for measuring temperature, humidity, gas and pressure sensing and can also be used for providing timely and comprehensive data for fermentation through combining with sampling analysis; steam sterilization and temperature and pressure control can be realized, the highest fermentation temperature is 45 DEG C, and the pressure is 0.02-0.03MPa; a sampling pipe, a discharging rake and a design that a material is prevented from falling from a fermentation chamber into an air distribution chamber are adopted; the rotten degree and bacterial count increasing, bacterium reducing and period shortening effects obtained by temperature and pressure controlled fermentation adopted by the device are better than those obtained by temperature and pressure uncontrolled fermentation and fermentation in a common plastic barrel with the same volume, the temperature and pressure controlled fermentation time is 10-12d, the temperature and pressure uncontrolled fermentation time is 19d, and the contrast time is 37d; after being treated by using the device, no fusarium wilts of cucumber are detected according to the contrast of 2*10<3> / g.

Description

technical field [0001] The invention belongs to the technical field of biological fermentation treatment of vegetable waste, and relates to a fermentation device and a use method for rapid decomposition of vegetable waste. Background technique [0002] With the increase of facility vegetable planting area in Tianjin, vegetable waste is increasing day by day, and plantation waste has become one of the problems of facility agriculture development and rural ecological environment in our city. Vegetable greenhouses and greenhouses produce a large amount of planting waste such as vegetable residues, weeds, and pulled out diseased plants every year, which are often discarded and piled outside the shed. Vegetable waste has high water content and is easy to rot, which breeds mosquitoes and flies Pests and germs etc. Planting waste is rich in nutrients, and discarded as waste, not only pollutes the environment, but also causes a great waste of resources. [0003] The traditional co...

Planting waste is rich in nutrients, discarded as waste, not only pollutes the environment, but also causes a great waste of resources

[0003] The traditional composting technology has the disadvantages of long fermentation time, incomplete harmlessness, and relatively extensive technology. Therefore, a fermentation device that can quickly decompose vegetable waste is studied to provide accurate data for the rapid and effective treatment of vegetable waste and realize vegetable waste. The purpose of waste reduction, harmlessness and resource utilization will be imperative

At present, there are many researches on domestic solid waste decomposing fermentation equipment, but the research on vegetable waste decomposing fermentation equipment and disinfection and sterilization system applied to vegetable waste sterilization has not been reported. In addition, the application of medium temperature (45 ℃) fermentation and high temperature There are few reports on accelerating the fermentation of vegetable waste by fermenting under constant pressure conditions of atmospheric pressure.
