Embodiment Construction

[0021] The present invention will be further described below in conjunction with specific application examples and accompanying drawings.

[0022] Such as Figure 1-3 As shown, a fast composting device of the present invention includes a fermentation tank 1, a spiral agitator 4 and a household solar water heater 5. The fermentation tank 1 is used to hold fermentation materials, and the fermentation tank 1 is a brick-concrete structure, and the inner surface Covered with cement, half buried in the ground, its longitudinal inner wall provides support for the spiral agitator 4, which is used to mechanically turn the materials in the fermentation tank, and the spiral agitator 4 is vertically placed inside the fermentation tank 1, located The lower third of the pool is deep and is powered by electric motor 6. The gas circuit and heat circulation pipeline system are buried at the bottom of the pool. The household solar water heater 5 communicates with the water pump and provides c...

Abstract

The invention discloses rapid composting device and method suitable for rural areas in North China. Mainly aiming at the problems that during the composting treatment of husbandry wastes by the existing composting technology, the temperature of a compost body is easily influenced by ambient temperature and the compost body is poor in ventilation effect, is not overturned very well, and is fermented for a long term, the invention provides the rapid composting device suitable for rural areas in North China. The device can be adapted to the low temperature characteristic of northern areas in autumn and winter, so as to achieve the effects of improving the fermentation temperature of the compost body, shortening fermentation starting time, realizing mechanical overturning, shortening the composting temperature in autumn and winter in northern areas and improving fertilizer producing efficiency. Simultaneously, The invention provides a composting method utilizing the device. According to the method, the rapid composting device is used together with a cellulose fungicide extracted from a corn fermentation product, so that the composting and conversion efficiency of straw and the like is improved, and the composting time is shortened.

Description

technical field [0001] The invention relates to a fast composting device suitable for northern rural areas and a method for fast composting using the device. The invention can adapt to the characteristics of low temperature and slow fermentation in autumn and winter in the northern region, improve the composting fermentation efficiency and shorten the composting time. The invention belongs to the technical field of agricultural production and environmental protection application. Background technique [0002] Under the background of the rapid development of agriculture and animal husbandry in my country, a large amount of waste is generated in the production process of agriculture and animal husbandry. The random discharge of agricultural and animal husbandry waste not only causes environmental pollution but also wastes waste resources. The composting of animal husbandry waste can solve the problem of reducing the amount of agricultural and animal husbandry waste and ...
