- 摘要:
- 为了实现低温下好氧颗粒污泥的快速培养，考察了分别投加人工晶核［Fe(OH)3］和混凝剂［聚合氯化铝(PAC)］对形成好氧颗粒污泥的影响。实验利用人工配制的模拟污水，以絮状普通活性污泥为接种污泥，采用SBR反应器在水温较低的条件下分别投加混凝剂和人工晶核实现了好氧颗粒污泥的快速培养及对水中污染物的去除。当水温由18 ℃逐渐降低至（10±1） ℃并长期保持低温下运行时，两种不同强化方式均能有效缩短好氧颗粒污泥的形成时间，其中投加人工晶核组在污泥浓度（10.22 g/L）、完成颗粒化耗时（24 d）、颗粒污泥平均粒径（1.75 mm）、污染物去除效果、抗冲击负荷能力等方面均优于投加混凝剂组（8.6 g/L、32 d、1.2 mm）。在低温下采用投加Fe(OH)3胶体人工强化措施，好氧颗粒污泥培养时间相较于投加混凝剂组缩短了8 d。
- Abstract:
- Enhanced effect of adding artificial core ［Fe(OH)3］ and coagulant［poly aluminum cloride (PAC)］ on formation of aerobic granular sludge was investigated to realize rapid aerobic granulation at low temperatures. By feeding artificial simulated wastewater and inoculating with flocculent activated sludge, rapid cultivation of aerobic granular sludge and the removal of pollutants from the wastewater were achieved by adding coagulant and artificial core at low water temperature in a SBR, respectively. When water temperature was gradually reduced from 18 ℃ to （10±1） ℃ and kept at low temperature for a long period, the formation time of aerobic granular sludge could be effectively shortened by the two different enhanced methods. Performance of adding artificial core group was superior to that of coagulant group in terms of sludge concentration (10.22 g/L, 8.6 g/L), time-consuming to complete granulation (24 d, 32 d), average particle size of granular sludge (1.75 mm, 1.2 mm), pollutants removal efficiency, impact load resistance and other aspects. Aerobic granulation time of enhanced measure of adding artificial Fe(OH)3 colloid was reduced by 8 days at low temperature compared with that of adding coagulant.
