Embodiment Construction

[0031] The specific implementation of the invention will be further described below in conjunction with the accompanying drawings.

[0032] Such as figure 1 As shown, a method for resource utilization of livestock and poultry breeding waste, comprising the following steps:

[0033] Collect feces, urine and waste generated in the production process of livestock and poultry breeding, and conduct solid-liquid separation to obtain solid waste and liquid waste.

[0034] Add biological bacteria starter to the solid waste, mix well, control the fermentation temperature between 55-65 degrees, and continue to ferment for 7-10 days, so that the biological bacteria and moisture indicators meet the requirements, and then analyze the quality indicators according to NY 525- The 2012 Organic Fertilizer Standard further adds nitrogen, phosphorus and potassium nutrients, and mixes them evenly, stacks and oxidizes; the oxidized materials are screened by screening equipment, and then packaged f...

Abstract

The invention discloses a livestock and poultry breeding waste resource utilization device and a method, and belongs to the technical field of livestock and poultry manure treatment. The method comprises the following steps: collecting excrement and urine generated in livestock and poultry breeding and wastes generated in a production process, and carrying out solid-liquid separation to obtain solid wastes and liquid wastes; adding a biological bacterium leavening agent into the solid wastes, uniformly mixing, controlling the fermentation temperature to be 55-65 DEG C, continuously fermenting for 7-10 days to enable the indexes of biological bacteria and moisture to meet the requirements, analyzing the quality indexes, further adding nitrogen, phosphorus and potassium nutrient substances according to the NY 525-2012 organic fertilizer standard, fully and uniformly mixing, and stacking and oxidizing; and screening the oxidized material by screening equipment and then carrying out packaging and deliverying out of a factory. The solid fertilizer and the liquid fertilizer can be prepared by recycling and efficiently utilizing the livestock and poultry breeding wastes.

Description

technical field [0001] The invention relates to the technical field of livestock and poultry manure treatment, in particular to a device and method for resource utilization of livestock and poultry breeding waste. Background technique [0002] The sewage of livestock and poultry farms contains a large amount of pollutants. According to the test results of large-scale farms by the environmental protection department, COD exceeds the standard by 50-70 times, BOD exceeds the standard by 70-80 times, and SS exceeds the standard by 12-20 times. The polluted sewage, solid feces and malodorous gas produced by large-scale farms have a large number of pollutants and are concentrated, especially water pollution and stench are the most serious pollution to the environment. According to the current state of environmental pollution management of large-scale farms in my country and the loss rate of normal water flushing manure, a pig farm with 10,000 heads has 40.7 tons and 30.3 tons of C...
