| 摘 要： | 食品加工厂剩余污泥含有丰富的有机质及氮、磷和微量元素等养分,可作为有机肥料和土壤改良剂。针对食品剩余污泥特性,采用高温好氧堆肥工艺,用牛粪、米糠、木片做添加剂,探讨了3组配比实验：第1桶,食品剩余污泥∶牛粪∶米糠∶木片=1∶0.5∶0.34∶0.71;第2桶,食品剩余污泥∶牛粪∶米糠∶木片=1∶0.5∶0.45∶0.86;第3桶,食品剩余污泥∶牛粪∶米糠∶木片=1∶0.5∶0.23∶0.56。综合实验结果分析,第2桶的效果最好,最后达到的参数指标温度、含水率、pH值、有机质含量、TOC的数值分别为28.1℃、30.6%、6.8、69.2%、29.1%。

| Abstract: | Excess sludge of food processing plants ,which contains rich organic matter and nitrogen ,phosphorus and trace elements ,can be used as organic fertilizer soil conditioner .Aimed at characteristics of excess sludge for food ,using high-temperature aerobic composting process ,taking cow dung ,rice bran ,wood as additive ,three groups of experiments were discussed ：the first bucket ,excess sludge of food∶cow dung∶ rice bran∶ wood =1∶0 .5∶0.34∶0 .71 ;the second bucket ,food residual sludge∶rice bran∶wood = 1∶0 .5∶0 .45∶0 .86 ;the third bucket , food residual sludge∶cow dung∶rice bran∶wood = 1∶0 .5∶0 .23∶0 .56 .Based on the analysis of experimental results ,the effect of the second barrel is the best ;the value of achieved parameters （temperature ,moisture content , pH value ,organic matter content ,the TOC） is 28 .1℃ ,30 .6% ,6 .8 ,69 .2% ,29 .1% ,respectively . |
