    摘要:

    為了解木質(zhì)纖維素分解復(fù)合菌劑CC-1接種牛糞堆肥化的效果,將堆料C/N比,、初始含水率,、通風(fēng)量及菌劑接種量進(jìn)行正交試驗(yàn),獲得該菌劑應(yīng)用的最佳工藝為堆料C/N比28,,初始含水率55%,,接種量0.8%(體積分?jǐn)?shù)),每天通風(fēng)20min(通氣量為5.09m3/(min〖DK〗·m3)),。在該工藝下,,接種CC-1的處理堆肥周期縮短,比接種EM和未接菌對(duì)照提前2d和3d達(dá)到高溫階段(>50℃),,提前8d降溫至40℃以下,;堆肥結(jié)束后,接種CC-1處理的pH值為7.9,,GI為106.5%,,其全氮含量比接種EM和未接菌對(duì)照高19.33%和27.35%,總養(yǎng)分高7.91%和23.95%,腐殖酸含量高16.38%和47.53%,;堆肥23d后,,接種CC-1的堆肥處理半纖維素分解率是接種EM和未接菌對(duì)照的1.2倍和1.8倍,纖維素分解率是接種EM和未接菌對(duì)照的1.8倍和2.1倍,。

    Abstract:

    Effect of independently developed microbial inoculum on cattle manure enhanced composting was studied, which was named CC-1 with high lignocellulose degradation ability. CC-1 was a mixture with Geotrichum candidum-BD1, Streptomyces thermocarboxydus-SM, Bacillus subtilis-KC and Coriolus versicolor, in which the first three kinds of microbial were selected from cattle manure in Beijing areas. The orthogonal composting test was conducted in simulated fermentation tanks to study the effects of different parameters such as C/N ratio(26, 28, 32), initial water content(55%, 60%, 65%), aeration rate (10min, 20 min, 30min ventilation every day, with 1.63m3/min ventilation pump power), and inoculation amount of microbial agents on cattle manure composting. And composting effect was evaluated from temperature changes, C/N, sensory effect (including material particle size and stench) and total nutrients contents. The results showed that the optimum control parameters were as follows: C/N was 28, water content of compost materials was 55%, microbial inoculation amount was 0.8%(volume ratio) and 20 minutes ventilation every day (ventilation volume was 5.09m3/(min·m3)). Then, with the optimum conditions, another composting was carried out to prove the effect of CC-1 on cattle manure composting, and the composting inoculated by EM and composting with non inoculum were taking as the controls. In this test, temperature changes and lignocellulose degradation during composting were measured. Besides, pH value, GI (germination index), TC, TN, TP, TK, and humic acid were determined when composting finished. The results showed that the composting period was shortened. The period of temperature rising to 50℃was 2 or 3 days earlier and the period of temperature decreasing to 40℃ below was 8 days earlier, compared to that inoculated by EM and non inoculated. When composting finished, pH value and GI of compost inoculated by CC-1 were 7.9 and 106.5%. Compared to compost that inoculated by EM and non-inoculated, the TN was 19.33% and 27.35% higher, total nutrient was 7.91% and 23.95% higher, and the humic acid was 16.38% and 47.53% higher in compost that inoculated by CC-1. Degradation ratios of hemi-cellulose and cellulose in compost inoculated by CC-1 was 1.2 and 1.8 times, and 1.8 and 2.1 times that in compost inoculated by EM and non-inoculated, respectively.
