摘要
以杭州市四堡污水处理厂的厌氧污泥为接种污泥,驯化富集了厌氧腐殖酸还原混合菌,加入不同的腐殖酸和碳源以优化驯化条件。结果表明,利用驯化厌氧污泥降解对乙酰氨基酚,1周降解时间内,驯化1个月的含腐殖酸还原混合菌群污泥比普通厌氧污泥降解率高34%,驯化半年的成熟厌氧污泥降解效果更好,降解率达90%以上。驯化厌氧污泥的最佳pH为7.0,Fe3+与腐殖酸同时存在时能进一步提高对乙酰氨基酚的厌氧生物降解效果。
The anaerobic sludge was sampled from Hangzhou Sibao wastewater treatment plant for the enrichment of humic acid reducing microorganisms. Different kinds of humic acid and carbon source were added into the sludge for optimizing the enrichment conditions. According to the results,comparing with common anaerobic sludge, the degradation efficiency with the sludge enriched for one month could be enhanced by 34% in a week, while the sludge enriched for half a year had better degradation efficiency which exceeded 90%. The optimal pH for the anaerobic sludge was 7.0. The coexistence of Fe^3＋ and humic acid in anaerobic sludge could further improve the acetaminophen degradation efficiency.
