Method for producing organic fertilizer by feces in meshy-bed duck breeding and production system for organic fertilizer

Abstract

The invention relates to a method for producing an organic fertilizer by the feces in meshy-bed duck breeding and a production system for the organic fertilizer. The method comprises the following steps of: breeding ducks in meshy beds: disposing a plurality of rows of meshy-bed support walls on flat ground, disposing meshy beds on the meshy-bed support walls, and forming a channel between the two adjacent meshy-bed support walls; collecting duck feces: disposing a reciprocating scraping plate in the channel, and discharging the duck feces in the channel into a collection box on a dirt discharge platform via the scraping plate; transporting duck feces: pushing the collection box onto the support frame of a transport vehicle, and transporting to a dirt centralized treatment place; composting and fermenting: uniformly stirring and mixing the measured duck feces with auxiliary raw materials having a ratio C / N of 20-30, a water content of 60-70% and a pH value of 6.0-8.0, building a heap at first, then turning the heap, and finally taking out the mixture and curing; and processing product: performing drying treatment on the semi-finished product after the composting treatment at first, and then performing quality detection on the product. The method and the production system disclosed by the invention realize resource utilization for duck feces, thus reducing environmental pollution and being capable of obtaining economic benefits.

Description

technical field [0001] The invention relates to a method and a production system for producing organic fertilizer by using duck manure raised in a net bed. Background technique [0002] Traditional farmers raise ducks on the ground, and the duck manure is excreted on the spot, and the manure cannot be collected, which seriously damages the surrounding environment, and there is also a serious risk of epidemics. With the large-scale development of the duck industry, most of the large-scale duck farms currently use mesh beds to facilitate the cleaning and management of duck manure and improve the effectiveness of epidemic prevention and control. However, due to the small space under the bed, the high-pressure water flushing cleaning management mode is adopted, resulting in a large amount of fecal sewage and high concentration of organic matter. After the manure is collected, the subsequent purification and treatment pressure is high, and it is difficult for enterprises to bear...

Problems solved by technology

After the feces are collected, the subsequent purification and treatment pressure is high, and it is difficult for enterprises to bear the infrastructure investment and operating costs of manure treatment and discharge.
