摘要: 为深入探究过氧化钙添加剂对结球甘蓝废弃物好氧堆肥无害化效果的影响,以结球甘蓝废弃物为主要原材料,米糠和猪粪为辅料,混合堆肥,共设置0(CK)、5%、10%、20% 4个过氧化钙添加量处理,测定堆肥温度及产品的有机质含量、全氮含量、腐熟度指标(pH、种子发芽指数、电导率)和无害化指标(粪大肠菌群数、蛔虫卵)。结果表明,添加过氧化钙有利于结球甘蓝堆肥积温的上升,添加5%、10%过氧化钙可以提升堆肥最高温度,但添加20%过氧化钙会降低堆肥最高温度;添加过氧化钙有利于有机质的降解,添加氧化钙处理有机质含量在堆肥结束时比CK低22.6%~66.7%;添加过氧化钙有利于堆肥的腐熟,种子发芽指数均达到腐熟要求(>70%);但只有添加20%过氧化钙才能使肥料达到无害化要求,粪大肠菌群数为24个/g。综上所述,如果是为了使结球甘蓝堆肥达到腐熟要求,同时考虑成本,建议往堆肥中添加5%过氧化钙;如果是为了使结球甘蓝堆肥达到无害化要求,建议添加20%过氧化钙。

Abstract: In order to further explore the effect of calcium peroxide additive on the harmless effect of aerobic composting of cabbage waste, cabbage waste was used as the main raw material, rice bran and pig manure were used as auxiliary materials, and mixed composting was carried out. Four calcium oxide addition treatments of 0(CK), 5%, 10%, and 20% were set up to determine the composting temperature and the organic matter content, total nitrogen content, maturity index (pH, seed germination index and conductivity) and harmless index (fecal coliform group and roundworm eggs) of the product. The results showed that the addition of calcium peroxide was beneficial to the increase of the accumulated temperature of the cabbage composting. The addition of 5% and 10% calcium peroxide could increase the maximum temperature of the compost, but the addition of 20% calcium peroxide would reduce the maximum temperature of the compost. The addition of calcium peroxide was beneficial to the degradation of organic matter. At the end of composting, the organic matter content of the calucium peroxide addition treatments was 22.6%-66.7% lower than that of CK. The addition of calcium peroxide was beneficial to the maturity of compost, and the seed germination index reached the maturity requirement (>70%). However, only adding 20% calcium peroxide could make the fertilizer meet the requirements of harmlessness, and the number of fecal coliforms was 24 per gram. In summary, if it was to make the cabbage compost meet the maturity requirements, taking into account the cost, it was recommended to add 5% calcium peroxide to the compost; if it was to make the cabbage compost to achieve harmless requirements, it was recommended to add 20% calcium peroxide.
