摘要:-
好氧顆粒污泥技術因具有沉降性能好、生物量大、抗沖擊能力強等特點而備受關注。通過研究和文獻分析，梳理了好氧顆粒污泥在中試研究及實際應用中的進展情況。關注了反應器容積、處理工藝、接種污泥、原水水質(zhì)、污泥濃度、顆粒粒徑及SVI等技術參數(shù)，并詳細闡述了中試和應用的經(jīng)典案例，總結了好氧顆粒污泥中試及應用的問題要點和成功的原因。提出了工程設計和運行建議，以及未來的發(fā)展方向。
Abstract:- Aerobic granular sludge technology has attracted much attention because of its good sedimentation performance, large biomass and resistance to impact load. Through research and literature analysis, development of the aerobic granular sludge in the pilot scale and practical application was combed. This paper focused on the reactor volume, treatment process, seed sludge, raw water quality, sludge concentration, particle size, SVI and other technical parameters. The typical cases of pilotscale test and application were expounded. The key issues and mechanism of these cases with aerobic granular sludge process were summarized. Some suggestions on engineering design and operation were put forward, as well as the development direction in the future.
