沼渣与畜禽粪便混合堆肥发酵效果的综合评价

采用正交试验设计方法实施了4组不同物料配比（以干质量计）沼渣与畜禽粪便混合物料堆肥试验，并采用模糊综合评价、灰色关联分析和属性识别法对其发酵效果进行了评价，为沼渣的肥料化利用提供参考。结果表明：T3（沼渣∶猪粪∶鸡粪=5.85∶8.49∶8.19）升温速率最快、高温维持时间最长，所达温度最高，T2（5.85∶7.425∶6.825）次之，T1（7.02∶7.425∶8.19）、T4（7.02∶8.49∶6.825）最差；从pH值、有机质、C/N、NH4＋-N、NH4＋-N/NO3--N和总养分等化学指标看，T2、T3发酵效果优于T1、T4；堆肥结束后，T1、T2、T3、T4粪大肠菌值分别为1、...

Summary:采用正交试验设计方法实施了4组不同物料配比（以干质量计）沼渣与畜禽粪便混合物料堆肥试验，并采用模糊综合评价、灰色关联分析和属性识别法对其发酵效果进行了评价，为沼渣的肥料化利用提供参考。结果表明：T3（沼渣∶猪粪∶鸡粪=5.85∶8.49∶8.19）升温速率最快、高温维持时间最长，所达温度最高，T2（5.85∶7.425∶6.825）次之，T1（7.02∶7.425∶8.19）、T4（7.02∶8.49∶6.825）最差；从pH值、有机质、C/N、NH4＋-N、NH4＋-N/NO3--N和总养分等化学指标看，T2、T3发酵效果优于T1、T4；堆肥结束后，T1、T2、T3、T4粪大肠菌值分别为1、10-1、10-2、1，发芽指数GI分别为96.72%、103.35%、98.42%、85.13%。上述3种评价方法对T1、T2、T3发酵效果评价一致：较好腐熟，但对T4评价结果分别为较好、基本和极未腐熟。综上所述，由单一指标或单一评价方法评判堆肥腐熟度有局限性。对堆肥发酵效果的评价应综合考虑物理、化学和生物学指标，对比3种评价方法原理，灰色关联分析法是评价堆肥发酵效果的较优方法。

In general biogas residue, along with livestock and poultry manure and straw as raw material, is not suitable for composting alone. Because it is mainly composed of cellulose and contains less readily biodegradable organic matter. The biogas residue mixed with livestock and poultry manure co-composting has two advantages. Firstly, the biogas residue fermentation is driven by easily degradable organic matter in manure. Secondly, the biogas residue is used as a conditioning agent during the composting, which is conducive to ventilation. A variety of comprehensive evaluation methods have been used for evaluating the compost maturity, but lack of study on the biogas residue mixed with livestock and poultry manure co-composting. In this study, four biogas residues mixed with pig manure and chicken manure co-composting experiments, with different material ratios （dry weight）, were tested for amount of biogas residue, pig manure, and chicken manure using orthogonal experiment design.
