摘要：

根据作者多年的工程设计及现场运行经验, 简述了UASB工艺、水解酸化工艺、接触氧化工艺启动与正常运行的技术要点。根据厌氧菌、兼氧菌与耗氧菌生长繁殖的不同理论, 分别从接种污泥的数量及来源、污水的水温及水质、人工培养及驯化过程的操作予以说明。总结了如何按期科学进水, 如何严格控制污水中的m(C)∶m(N)∶m(P)及运行水温等。可供工程设计人员及企业污水处理站同行参考。

Abstract:

Organic wastewater is usually treated by biochemical treatment processes, such as USAB, hydrolysis acidification, contact oxidation. According to the experiences of engineering design and practical directions, some technical main points are expounded. Based on different theories of growing and breeding of anaerobic bacteria,aerobic bacteria, the amount and source of seeding sludge, the temperature and quality of the wastewater, the artificial-cultivation and domestication are explained. In addition, some special experiences and opinions about how to control m(C)∶m(N)∶m(P)and the water temperature during operation are put forward, providing references for personnel working on engineering design and wastewater treatment.

Key words: upflow anaerobic sludge bed, hydrolytic acidification, contact oxidation
