Abstract

Abstract

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.
