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％。

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 .
