摘要:

综述了现有的各种处理方法, 包括化学氧化法、溶剂萃取法、吸附法、焚烧法、光催化法、生化处理法等, 对各种方法的优缺点进行了比较。重点评价了超声处理新工艺。针对高浓度难降解有机废水生化处理的关键问题, 对超声波机理和有机物生物可降解性的主要影响因素进行了分析。在此基础上, 提出超声波预处理与生物处理相结合的新方法, 并以碱法草浆与靛蓝染料废水的实例说明该法的可行性。

Abstract:

It reviews currently available technologies,including chemical oxidation, solvent extraction, adsorption, incineration, photocatalysis and biochemical.Ultrasonic degradation is intensively studied in terms of mechanisms and important operative parameters. Based on the review and the analysis of the key issues in biodegradability of refractory chemical, an ultrasonic- biotreatment process is proposed. The feasibility of the process is explained by supplying examples, including the treatment of alkaline paper and pulp wastewater and dyeing wastewater.

Key words: organic wastewater, refractory, ult rasonic
