摘要: 对市政剩余污泥CaO处理及生物干化过程中的温度、pH、含水量等进行了研究,并与未经碱处理的市政剩余污泥进行了对比分析。发现市政剩余污泥具有良好的pH缓冲能力,且CaO处理可以在一定程度上提高其生物干化温度。在此基础上,对经CaO处理和未处理两种条件下的市政剩余污泥生物干化过程中的细菌群落变化进行了分析,结果表明不同处理方式以及生物干化时间对污泥基质中细菌群落的影响较为明显。该研究为进一步阐明市政剩余污泥好氧生物干化的微生物群落更替规律奠定了初步基础。

Abstract: In this study, temperature, pH, and moisture content of the municipal excess sludge treated with CaO during the biodrying process were analyzed, and the obtained data were compared with excess sludge treated without CaO. It was observed that the sludge waste exhibited good buffering capacity of pH, and could improve the biodrying temperature to a certain degree after treated with CaO. Moreover, the variations in bacterial communities during the biodrying process of municipal excess sludge biodrying were analyzed based on two different conditions (with and without CaO treatment). It was found that the two different treatment methods and biodrying period had a significant effect on the bacterial communities in the sludge substrate. The study facilitates the preliminary foundation to further clarify the succession rules of microbial communities during municipal excess sludge biodrying using aerobic fermentation.

Key words: municipal excess sludge, biodrying; CaO;bacterial communities
