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

在这项研究中，堆肥实验的目的是回收热量的牛粪堆。当原料牛粪的含水量为约85%时，在牛粪中加入水分调节剂，即干叶、木屑和沸石，饲料堆肥物质的含水量已经达到约78%。称为“KAGUYAHIME”的堆肥反应器的体积为12.3升，饲料堆肥物质的重量为6.0kg。通过鼓风机提供强制通风。实验采用不同的通气速率，0.7 l/min和1.4 l/min进行。在好氧条件下，最高温度在36 ℃至38 ℃之间变化，通气速率为0.7 l/min，经过4至8天。在有机废物的生物降解下，从堆肥中回收的热量在最初10天的持续时间内是有用的。

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.
