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。
It reviews currently available technologies,including chemical oxidation, solvent extraction, adsorption, incineration, photocatalysis 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 biodegradability 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.
