- 摘要:
- 利用热水解污泥厌氧产酸制备反硝化碳源，是实现污泥碳资源化的有效途径。为此，探究了污泥厌氧产酸效果、产酸液作为反硝化碳源的可行性及微生物群落演变规律。结果表明，在适宜产酸条件下污泥产酸液的SCOD为20.0~29.5 g/L，VFAs为7.7~13.2 g/L，乙酸占比约为50%，NH4+-N为1 060~1 917 mg/L。反硝化速率试验结果显示，以产酸液为碳源时，反硝化速率为1.784 mg/（gMLVSS·h），可达到乙酸钠反硝化速率的83%，具备作为反硝化碳源的潜力。污泥厌氧产酸过程中，水解发酵的两大主要菌属即拟杆菌（Bacteroides）和梭状芽孢杆菌（Clostridium）的丰度显著提高，优势产甲烷菌为甲烷短杆菌属（Methanobrevibacter）。研究结果证实了热水解污泥厌氧产酸制备反硝化碳源的可行性，后续可通过强化产甲烷抑制、优化氮磷去除进一步提升技术实用性。
- Abstract:
- Producing denitrification carbon sources through anaerobic acidogenesis of thermally hydrolyzed sludge is an effective way to realize the carbon resource utilization of sludge. To this end, this study explored the effect of anaerobic acidogenesis of sludge, the feasibility of using the acidified liquid as a denitrification carbon source, and the evolution law of the microbial community. The results showed that under suitable acidogenesis conditions, the SCOD of the sludge acidified liquid was 20.0-29.5 g/L, VFAs were 7.7-13.2 g/L, the proportion of acetic acid was about 50%, and NH4+-N was 1 060-1 917 mg/L. The results of the denitrification rate test showed that when the acidified liquid was used as the carbon source, the denitrification rate was 1.784 mg/(gMLVSS·h), which could reach 83% of the denitrification rate of sodium acetate, indicating that it had the potential to serve as a denitrification carbon source. During the anaerobic acidogenesis process of sludge, the relative abundances of Bacteroides and Clostridium, the two main genera responsible for hydrolysis and fermentation, increased significantly, and the dominant methanogen was Methanobrevibacter. The research results confirm the feasibility of preparing denitrification carbon sources through anaerobic acidogenesis of thermally hydrolyzed sludge, and the practicality of the technology can be further improved by strengthening methanogenesis inhibition and optimizing nitrogen and phosphorus removal in subsequent studies.
