中文摘要：

厌氧序批式反应器（ASBR）初次启动用厌氧消化污泥接种，比较了投加聚季铵盐（A柱）与空白对照（B柱）2个反应器的颗粒污泥形成过程。启动后以每隔2d投加1次的投加方式向反应器中不断补充聚季钱盐，聚季铵盐投加质量与污泥质量之比取1．6mg／g。结果表明，A柱颗粒污泥平均粒径达到0．72mm仅需73d，比B柱提前了25d。A柱在启动56d后COD负荷达到10g／（L·d），形成的颗粒污泥平均粒径大于B柱（0．55mm），产甲烷活性也较高。所以投加聚季铵盐能有效促进污泥颗粒化进程。

英文摘要：

Two anaerobic sequencing batch reactors （ASBR） were inoculated with anaerobically digested sludge. The reactor A （ fed with polyquatemary ammonium salt） was compared with the reactor B （control） in order to contrast the development of granular sludge. Since start-up, the polyquatemary ammonium salt was added into the reactor A at interval of once per 2 d, and the mass ratio of polyquaternary ammonium salt to sludge was 1.6 mg/g. The results show that the average diameter of granular sludge in the reactor A is 0.72 mm within 73 d, reducing granulation times by approximately 25 d compared with the reactor B. The COD loading rate achieves 10 g/（ L · d） in the reactor A after start-up for 56 d, and the average diameter of granular sludge is bigger than the reactor B （0.55 mm）. The granular sludge has higher methanogenic activity in the reactor A. Therefore adding polyquaternary ammonium salt into the ASBR can effectively enhance granulation.
