Baf has many advantages, such as small volume, little covering earth and hydraulic retention time ( hrt ), high treatment efficiency and effluent water quality, low investment and running cost etc. baf has been used widely for many years in the world and been used to treat several wastewater in our country. in this paper, baf was studied on guanting reservoir water source treatment with pilot scale and homemade expanded clay as filtration media
曝氣生物濾池（ biologicalaeratedfilter ，簡稱baf ，或biologicalfiltrationoxidizationreactor ，簡稱biofor ）工藝具有體積小、容積負荷高、水力負荷大、水力停留時間短、所需基建投資少、處理出水水質好等特點，國外已廣泛應用，國內也在多個行業的水處理中成功應用。 -
Multistage fluidized - bed bioreactor with external circulation has been in use in the production of fuel alcohol by immobilized yeast cells technique. as a new - style reactor. it has the advantage of high conversion, complete reaction and little damage to immobilized yeast cells. flow properties is the foundation of reactor ' s physical transmission process. and it is the key factor of deciding whether the auxiliary material conversion is high or low. at present, the study on flow properties of multistage fluidized - bed bioreactor with external circulation at a pilot scale is rarely reported
多級外循環流化床生物反應器作為一種新型生物反應器，由於具有轉化率高、反應徹底、對顆粒損傷少等優點在固定化細胞制取燃料酒精技術上得到應用。但是，國內關于中試規模多級外循環流化床反應器流動特性的研究還很少，而流動特性是反應器物理傳遞過程的基礎，是研究物料在反應器中轉化率高低的重要因素，因此，弄清楚外循環流化床反應器的流動特性是非常重要的。
