偶氮染料的厌氧-好氧生物降解过程和影响因素
Biodegradation Process and Influencing Factors of Azo Using Anaerobic-aerobic Technology
摘要
Abstract
The total amount and kinds of azo dyes are the biggest of synthetic dyes. Usually the anaerobic-aerobic process is adopted to degrade the azo dyes, for the azo dyes can be reduced to aromatic amines in anaerobic condition, and then degraded completely in the following aerobic condition. Anaerobic reduction process of azo dyes is influenced by the structure and concentration of azo dye, the kind and concentration of substrates, other electron acceptors, redox mediator, environmental parameters such as temperature and dissolved oxygen, and hydraulic retention time. The degradation of aromatic amines under aerobic conditions is affected by its own structure, concentration, additional carbon, degradation system etc. and disturbed by the auto-oxidation of aromatic amines. Good conditions should be provided to improve the azo dyes degradation efficiency of anaerobic-aerobic technology in practical wastewater treatment.关键词
