光催化-膜分离三相流化床循环反应装置处理酸性红B废水
Treatment of Acid Red B wastewater by three-phase fluidized bed recycle equipment coupling with photocatalysis oxidation and organic membrane separation
摘要
Abstract
A new type of three-phase fluidized bed recycle equipment, coupling with the technology of pho- tocatalysis and organic membrane separation, was designed, and the influencing factors during photocatalytic de- grading Acid Red B with TiO2 were investigated. The results showed that it was helpful to raise the degradation rate of membrane effluent as the membrane flux and Acid Red B concentration reduced. The degradation rate of wastewater first increased and then decreased with increasing aeration flux in the bottom of photocatalytic reactor, but the degradation rate fluctuation in the membrane separator always increased, and the optimal value of the aer- ation flux was 1.00 m3/h. Multi-ultraviolet light arrangement in the photocatalytic reactor was conducive to the stability during the reactor run. The recycle equipment can treat Acid Red B wastewater effectively.关键词
