摘要
在厌氧反应器启动初期添加絮凝剂需考虑絮凝剂对厌氧微生物所产生的抑制影响,通过对聚合氯化铝(PAC)、聚丙烯酰胺(PAM)、聚季胺盐不同絮凝剂的生物化学甲烷势(BMP)测定和厌氧毒性测定(ATA),评价了其厌氧生物可降解性和絮凝剂对厌氧微生物产甲烷活性的影响,对比了所形成的生物絮体在沉降性能和抗破散强度方面的差别。确定以聚季胺盐作为厌氧污泥颗粒化促进剂,建议采用间隔10d的多次添加方式及反应器中聚季胺盐质量浓度为10mg/L。
The restraint of floccules on anaerobic microbe should be studied during the course of start-up in the anaerobic reactor. The enhancements of three different types of floccules （polyaluminium chloride, polyacrylamide, polyquantemary amine） on sludge granulation were evaluation by methods of biochemical methane potential （BMP） test and anaerobic toxicity assay （ATA）, their anaerobic biodegradabilities and the influences on specific methanogenic activities were assessed, and the settling performance and intensities of the flocculates were compared. From results of experiment, polyquantemary amine was finally determined as enhancing agent using in anaerobic sludge granulation. It is suggested that polyquantemary amine is dosed into reactor at 10 d intervals and the recommended dosage is about 10 mg/L.
