摘要
[目的]研究两相生物法与光催化复合处理亚麻废水的效果。[方法]针对亚麻生产废水的特点,采用两相生物法与光催化复合工艺处理沤麻废水,研究该工艺的处理效果。[结果]经过该系统处理的亚麻沤制废水CODCr总去除率达到97.9%,SS总去除率达到89.2%,色度总去除率达到80.0%,pH为6.8左右。各项指标均达到《污水综合排放标准》二级标准要求。[结论]该研究可为亚麻生产废水提供一种经济有效的处理工艺。
[Objective]The research aimed to study treatment effect of the flax wastewater by two-phase biological method and photocatalysis.[Method]For characteristics of the flax wastewater,retting flax wastewater was treated by two-phase biological method and photocatalysis,and treatment effect of the process was studied.[Result] After treated by the system,total removal rates of CODCr,SS and chroma in retting flax wastewater respectively reached 97.9%,89.2% and 80.0%,while pH was 6.8.Each indicator reached level-two standard of Comprehensive Emission Standard of the Sewage.[Conclusion]The research could provide a kind of economic and effective treatment process for flax wastewater.
