章節(jié)摘錄

版權(quán)頁(yè)：   插圖：   In the submerged membrane photocatalytic reactor（SMPR）,the catalyst is suspended in an openair reaction environment,the membrane is immersed in thebatch and the permeate is sucked by means of a pump. Fu et al.[162]studied the degradation of fulvicacid by using synthesized nanostructured TiO2／silicagel catalyst particles in a submerged membranephotoreactor.They investigated the effects of someoperative conditions,such as catalyst concentration,pH.and airflow on the performance of the overallprocess and demonstrated that a reduction of membrane fouling,and therefore,an improvement of thepermeate flux rate,can be obtained using nanostruc-tured TiO2.This synthesized catalyst has an averageparticle size of 50μm,which resulted small enoughfor the suspension,but big enough to avoid membrane fouling and to allow its easy separation. Moreover,it is possible to prevent catalyst deposition and to reduce the membrane fouling whichcauses the membrane flux decline by controllingthe hydrodynamic conditions near membranesurface.A useful strategy in this context is gas sparging at the bottom of the membrane[163,164]. The efficiency of a hybrid system.combining a low-pressure submerged module in direct contact with thephotocatalytic environment,was studied by Chin gt al.[155]for the remoral of bisphenol-A in water.In particular,studying the factor affecting the performance of the SMPR,they observed that the aeration,allowing amechanical agitanon,reduces the fouling of the mem-brane and keeps the TiO2,well suspended in thesolution,acting also on the size of catalyst aggregates.However.beyond an aeration of 0.51 min-1 no enhancement of photodegradation rate was achieved,probablydue to the presence of bubble clouds that could atcenuate UV light transmission in the photoreactor.
