| 中文摘要: |
| 研究了外源添加不同配比的复合微生物菌剂对河道底泥堆肥发酵的影响，为筛选促腐效果更
好的优质微生物菌种配方提供依据。通过不同比例组成的微生物菌剂进行底泥堆肥试验，并对堆肥温度、
水分、pH 值、电导率、可溶性有机碳、氮等进行分析。结果表明，添加的复合菌剂以嗜热脂肪芽孢杆菌∶枯
草芽孢杆菌∶地衣芽孢杆菌∶巨大芽孢杆菌=2∶1∶1∶1 的配比效果最好，2 d 就能达到最高温度63.3℃，
明显加速堆肥的腐熟；以底泥为原料的堆肥过程升温迅速，具备堆肥资源化利用的良好前景。可望为城市
河道底泥的科学处理，纯净城市水体和陆地生态环境提供有用的数据支持，为开发相应的技术，缓解城市
生态环境的容量压力，促进城市社会、经济可持续发展做出贡献。 |
| 英文摘要: |
| We studied the effects of complex microbial inoculums with different mixture ratio of microorganisms
on river sediment composting，to select better formula of microbial strains. The experiment was conducted through
adding different proportions of microbial inoculants to river sediment during composting，and the composting
temperature，moisture content，pH，conductivity，dissolved organic carbon（ DOC），dissolved organic
nitrogen（ DON） were analyzed. The best proportion of the complex microbial inoculums was found（ Bacillus
stearothermophilus∶B. subtilis∶B. lincheniformis∶B. megaterium = 2∶1∶1∶1），this proportion of the complex
significantly accelerated sediment composting，the compost reached the highest temperature（ 63.3 ℃） within 2
days，revealing that adding extra complex microbial inoculums could accelerate the composting process. Taking
sediment as composting materials provided a rapidly warming process of composting，showing good prospects for
reutilization of river sediment to be composting. |
