铜和镍离子对好氧颗粒污泥处理效果的影响及改进策略

好氧颗粒污泥由于具有微生物量丰富、抗冲击负荷能力强等优点，成为目前处理印染废水的主流方法之一，但印染废水中存在的Cu2+和Ni2+会对好氧颗粒污泥处理过程产生各种影响,使好氧颗粒污泥的处理效果下降. 通过梳理文献分析Cu2+和Ni2+对好氧颗粒污泥微生物种群分布、污泥絮凝沉降性、反应动力学的影响，根据Cu2+和Ni2+对好氧颗粒污泥产生的不同影响提出采取预处理、解吸、调整工艺参数等改进策略. 通过采用改进策略，可使好氧颗粒污泥在不利条件下仍能有效处理印染废水. 研究结论为好氧颗粒污泥进一步探索与应用提供建议.

Effect of Copper and Nickel Ions on Aerobic Granular Sludge Treatment and Improvement Strategy

Aerobic granular sludge has become one of the mainstream methods for the treatment of printing and dyeing wastewater due to its rich microbial biomass and strong impact resistance. However, the presence of Cu2+ and Ni2+ in the printing and dyeing wastewater will have various effects on the aerobic granular sludge treatment process, which will reduce the treatment effect of aerobic granular sludge. Based on the literature review, the effects of Cu2+ and Ni2+ on the microbial population distribution of aerobic granular sludge, sludge flocculation and sedimentation, and reaction kinetics were analyzed. According to the different effects of Cu2+ and Ni2+ on aerobic granular sludge, improvement strategies such as pretreatment, desorption and adjustment of process parameters were proposed. By adopting improved strategies, aerobic granular sludge can still effectively treat printing and dyeing wastewater under adverse conditions. The research results provide suggestions for further exploration and application of aerobic granular sludge.
