从无害化处理、资源化利用的角度对生物环保养猪产生的废弃物进行了综合分析,测定了生物环保养猪垫料未使用和使用18个月后废弃物的有机质、大中微量元素含量,并对废弃物进行了有机肥品质评价。结果表明:生物环保养猪产生的废弃物中含有大量的有机质、氮、磷、钾等常量元素和丰富的铁、锰、镁、锌等微量元素,结合全国有机肥料品质要素分级标准,综合评定生物环保养猪产生的废弃物符合二级有机肥的标准。 From the perspective of innocuous treatment and resource utilization, the comprehensive analysis of the wastes produced by pigs kept in environmental protection was carried out. The organic matter, the trace elements Content, and the waste organic fertilizer quality evaluation. The results showed that the wastes produced by pigs raised in environmental protection pigs contained a large amount of macroelements such as organic matter, nitrogen, phosphorus and potassium, and abundant trace elements such as iron, manganese, magnesium and zinc. Combining with the grading standards of the national organic fertilizer quality factors, Waste produced by bio-environmental pigs meets the standard of secondary organic fertilizer.
