密闭式高温发酵设备在肉鸡养殖场中的应用

Application of closed type high temperature fermentation equipment in a broiler farm

苏家屯某养鸡场与辽宁省某环保科技企业合作,运用该环保企业生产研发的密闭式高温发酵设备,通过密闭的好氧发酵模式处理鸡粪便,生产有机肥。其过程安全环保,成本较低,具有一定的经济效益,较为适合作为规模化畜禽养殖场粪污无害化治理。根据该企业提供该场处理后样品检测报告显示,初始鲜粪的含水率约为50%（鲜粪含水率数值与集粪方式有关,数值范围偏低需要确定）,经处理后成品含水率为37.23%,鲜粪有机质含量为30%-40%,经处理后成品有机质含量50%-55%,氮磷钾比例呈升高的趋势,有效地保留了氮磷钾等养分,因此有利于作为有机肥使用。

A chicken farm in Sujiatun Shenyang cooperate with a environmental science and technology enterprises in Liaoning Province,using the environmental protection enterprise production and development of a sealed high-temperature fermentation equipment, the production of organic fertilizer was produced by the treatment of chicken manure with fully enclosed aerobic fermentation mode. The process is safe and environmental protection, low cost, and has a certain economic benefits, more suitable for large-scale livestock and poultry farm manure harmless treatment. According to the enterprise to provide the treatment after sample inspection report shows that initial fresh dung in the water rate is about 50%. After treatment finished water rate 37.23%, organic matter content in fresh feces is 30%-40%, after processing after the organic matter content of the finished product is 50%-55%, the proportion of nitrogen, phosphorus and potassium was increased, effective retention of nitrogen, phosphorus and potassium and other nutrients, so it is in favor of the use of organic fertilizer.
