| 摘 要： | 以福清生活污泥为原料,草木灰及鸡粪为辅料,添加枯草芽孢杆菌(T1处理)和BFA腐殖酸(T2处理)进行堆肥,研究微生物菌剂对堆肥过程中堆体(表层和中间)温度、水分、腐殖酸、有机质、全氮、全磷、全钾和GI(种子发芽率指数)的影响。结果表明:T1和T2处理较对照升温迅速,且高温期的温度高,维持时间长;堆肥期内各处理的水分均逐渐减少,而T2处理水分减少最多,减少了22.9%,其次是T1处理减少了19.6%,而对照仅减少了16.9%;堆肥40d后,T1、T2处理的堆体腐殖酸、有机质、全氮和全钾含量均高于对照;堆肥40d后,各处理的GI值均大于50%,其中T2处理的GI值大于80%,堆肥腐熟度达到最佳。

| Abstract: | Addition of microbial agents to the sludge collected in the city of Fuqing for composting was investigated.Changes on the surface and center temperatures,contents of moisture, humus acid, organic matters, total nitrogen, total phosphorus and total potassium, as well as the seed germination rate index (GI)of the compost during the fermentation process were monitored as the sewage sludge was mixed with plant ash, chicken manure, Bacillus subtilis (Agent A, Treatment T1) and/or BFA humus acid (Agents B, Treatment T2).The results showed that (a) T1 and T2 rendered the compost to reach a higher maximin temperature faster and maintain it longer than CK did;(b) the moisture content in compost decreased as the fermentation progressed, with the greatest reduction by T2 at 22.9%, followed by T1 at 19.6% and CK at 16.9%;(c) after 40 d composting, the humus acids, organic matters, total nitrogen and total potassium contents in the composts were higher with T1 or T2 than CK;and (d) the 40 d fermentation resulted in GIs by all treatments greater than 50%, and that of T2 beyond 80% achievinga maximal degree of composting effect. |
