Treatment of the Flax Wastewater by Two-phase Biological Method and Photocatalysis

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 CODer, 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.
