Development of the composting process of the heat recovered on the cow manure

在本研究中，进行了堆肥实验，目的是回收一堆牛粪中的热量。当原牛粪含水率为85%左右时，在牛粪中加入干叶、木屑、沸石等水分调节剂，饲料堆肥物质含水率约为78%。“KAGUYAHIME”堆肥反应器的体积为12.3升，饲料堆肥物质的重量为6.0kg。强制充气是由鼓风机提供的。实验以0.7 1/min和1.4 1/min的曝气速率进行。在有氧条件下，4 ~ 8天后，最高温度为36℃~ 38℃，曝气速率为0.7 1/min。结果表明，在有机废物生物降解的条件下，堆肥的热回收在前10天是有用的。

In this study, the composting experiments took place with an aim to recover the heat from the pile of cow manure. When the moisture content of the raw cowcack was about 85%, the moisture adjustments, namely dry leaf, woodchip and zeolite, were added in the cowcack and the moisture content of the feed composting matter had gone of about 78%. The volume of the composting reactors that were referred to "KAGUYAHIME" was 12.3 liters and the weight of the feed composting matter was 6.0kg. The forced aeration was provided by an air blower. Experiments were performed with different aeration rates, 0.7 1/min and 1.4 1/min. Maximum temperatures varied from 36 degrees centigrade to 38 in the experiment with the aeration rate of 0.7 1/min after from 4 to 8 days under aerobic conditions.In the results, the heat recovery from the composting was useful for the duration of early 10 days under the biological degradation of organic wastes.
