【摘要】：以中藥渣與城市污泥為原料進(jìn)行共堆肥實(shí)驗(yàn),考察了不同物料質(zhì)量配比與中藥渣不同時間投加條件下,堆體在堆肥過程中溫度、有機(jī)質(zhì)、揮發(fā)氨、蛋白酶活性等理化指標(biāo)的變化情況,確定了最佳的物料質(zhì)量配比與中藥渣投加時間;同時探討了中藥渣投加對堆肥過程中溶解性有機(jī)質(zhì)(DOM)及微生物群落結(jié)構(gòu)的影響.結(jié)果表明,中藥渣作為外加碳源投加后(60 g中藥渣+300 g污泥),提高了堆體的溫度,減少了氨的揮發(fā),且提高了堆體中蛋白酶的活性,氨的揮發(fā)量減少了35.9%,蛋白酶的含量提高了80.5%.同時中藥渣可作為調(diào)理劑,在堆肥前期投加,促進(jìn)了有機(jī)質(zhì)的降解,從而加快了堆肥的進(jìn)程.而通過對DOM的紫外-可見和熒光光譜特征分析表明,投加中藥渣有利于提高堆肥的腐殖化程度;同時通過磷脂脂肪酸(PLFA)分析可以發(fā)現(xiàn),投加中藥渣后使得堆體中革蘭氏陰性菌與真菌的數(shù)量有所提高.
[Abstract]:The co-composting experiment was carried out with Chinese medicine residue and municipal sludge as raw materials. The temperature, organic matter and volatile ammonia in the composting process were investigated under the conditions of different material mass ratio and different time addition of Chinese medicine residue. The changes of physicochemical indexes, such as protease activity, determined the best material mass ratio and the time of Chinese medicine residue addition, and discussed the effect of traditional Chinese medicine residue addition on dissolved organic matter (DOM) and microbial community structure in composting process. The results showed that the temperature of the reactor was increased, ammonia volatilization was reduced, and the activity of protease was increased after adding 60 g Chinese medicine residue as an additional carbon source. The volatilization of ammonia was reduced by 35.9m, and the content of protease was increased by 80.5%. At the same time, traditional Chinese medicine residue can be used as a conditioning agent, which can accelerate the degradation of organic matter and accelerate the process of composting. The analysis of UV-Vis and fluorescence spectra of DOM showed that the addition of Chinese medicine residue could improve the humification of compost, and the results of phospholipid fatty acid analysis showed that, The addition of Chinese medicine residue increased the number of Gram-negative bacteria and fungi in the heap.
