[0056] How to use the fermentation device

[0057] 1. Raw material pretreatment

[0058]According to the principle of dry and wet, mix livestock and poultry manure, bacteria and other auxiliary materials evenly, so that the carbon-nitrogen ratio of the fermentation material reaches 25-30:1, and the moisture reaches 55-60%. The livestock and poultry manure mentioned above refers to the manure produced by livestock and poultry such as cattle, pigs, chickens, sheep, horses, and ducks; Streptomyces microflavus, Trichoderma longbrachiatum and Bacillus mucilaginosus. Other auxiliary materials refer to mushroom slag, lignite, etc.; the weight-number ratio of livestock and poultry manure: other auxiliary materials: bacterial strains is 80:19.9:0.1.

[0059] 2. Preparation before loading

[0060] Before loading, it is necessary to make some preparations for the fermentation device. First, insert the flange insulation plug equipped with a sealing ring into the sampling port and th...

[0070] Application effect of fermentation device

[0071] The following is the application test of the fermentation device used for rapid decomposing of livestock and poultry manure in improving the degree of decomposing, available nutrients and bacteria count, and shortening the fermentation time.

[0072] The raw material is chicken manure + cow dung at a weight ratio of 1:1, and the auxiliary material is mushroom dregs and lignite at a weight ratio of 1:1, wherein the weight ratio of livestock and poultry manure: auxiliary material: bacterial strain is 80:19.9:0.1, and the water content is 55 % to 60%, the volume is 170L, the room temperature is 25°C, and there are 4 treatments. Treatment 1: aerobic fermentation with temperature and pressure control in the device of the invention; treatment 2: aerobic fermentation with temperature control in the device of the invention; treatment 3: natural (without temperature control) pressure) aerobic fermentation; treatment 4: natura...

Abstract

The invention discloses a fermentation device for the rapid thorough decomposition of livestock excrements and a using method and effects thereof. The device is beautiful and practical in design, has hollow cylinder shaped appearance, and comprises a fermentation system, a monitoring system, a ventilation system, a percolation and collection system and a heat preservation system. The device can carry out sensing determination on temperature and humidity, gas and pressure, and in combination with sampling analysis, provides timely and comprehensive data for the fermentation of livestock; the device can be subjected to full-sealed heat preservation, the temperature and pressure of the device can be controlled, the highest fermentation temperature is 55-60 DEG C, and the pressure is 0.02-0.03 Mpa; according to sampling, discharging, cleaning and appearance requirements, auxiliary tools such as a sampling tube and a discharge scraping rake are arranged and a design for preventing materials from falling into an air distribution chamber from a fermentation chamber is performed; under the action of temperature and pressure control and the like, the device is adopted for fermenting livestock excrements, through contrast in the aspects of available nutrients, bacterial count, escherichia coli and fermentation period, the fermentation effect of the device is better than those of temperature / pressure-uncontrollable devices and comparable common plastic buckets with a same volume, temperature / pressure-controllable fermentation is implemented in 12-15 days, and temperature / pressure-uncontrollable fermentation is implemented in 18 days, 42 days in contrast.

Description

technical field [0001] The invention belongs to the technical field of biological fermentation treatment of livestock and poultry manure, and relates to a fermentation device for rapid decomposing of livestock and poultry manure, its use method and effect. Background technique [0002] The large-scale development of pollution-free, green agriculture, organic agriculture and facility agriculture means that the demand for organic fertilizers as base fertilizers will continue to increase. At present, most of the sources of organic fertilizer in protected vegetable cultivation are supplied by the traditional composting method of livestock and poultry manure. Due to the long and extensive stacking time and incomplete fermentation, it is completely inconsistent with the pace of vigorously developing protected agriculture. For the application of organic fertilizers in facility agriculture, except for a very small number of decomposed organic fertilizer products purchased from organ...
