class="NyNewsdetail_con"> <div>　　UASB厭氧反應(yīng)器由厭氧塔塔塔體為玻璃鋼整體纏繞的圓筒型塔體，無分段連接法蘭。具體結(jié)構(gòu)由塔體、布水系統(tǒng)、污泥床、生物載體區(qū)、三相分離器、浮渣速排裝置和回流系統(tǒng)等組成。<br /> </div><div>　　UASB厭氧反應(yīng)器特點(diǎn)：<br /> </div><div>　　(1)UBF反應(yīng)器結(jié)構(gòu)緊湊，集厭氧生物濾池(AF)與升流式厭氧污泥反應(yīng)器(UASB)，和沉淀于一體。<br /> </div><div>　　(2)UBF反應(yīng)器的最大特點(diǎn)是能在反應(yīng)器內(nèi)形成顆粒污泥，使反應(yīng)器內(nèi)平均污泥濃度達(dá)到30～40g/L,底部污泥濃度可高達(dá)60～80g/L。<br /> </div><div>　　(3)UBF反應(yīng)器具有很高的容積負(fù)荷，一般為10～20kgCODCr/(m3·d)，最高可達(dá)30kgCODcr/(m3·d)。而且水力停留時(shí)間短，通常采用中溫厭氧消化，有時(shí)可以在常溫下運(yùn)行。<br /> </div><div>　　(4)反應(yīng)器內(nèi)設(shè)三相分離器，在沉淀區(qū)分離的污泥能自動(dòng)回流到反應(yīng)區(qū)，而切還增加了回流裝置。并利用自身產(chǎn)生的沼氣和進(jìn)水水流來實(shí)現(xiàn)攪拌混合，也不需要混合攪拌設(shè)備。因此，簡(jiǎn)化了工藝環(huán)節(jié)和減少了系統(tǒng)工藝設(shè)備，維護(hù)運(yùn)行較簡(jiǎn)單。<br /> </div><div>　　(5)UBF反應(yīng)器內(nèi)設(shè)有生物載體區(qū)，是一種懸浮生長型和附著生長的厭氧消化方法，厭氧復(fù)合床反應(yīng)器(UBF)與厭氧生物濾池相比，減少了填料層的高度，也就減少了濾池被堵塞的可能性；與UASB法相比，填料層既是厭氧微生物的載體，又可截留水流中的懸浮厭氧活性污泥碎片，從而能使厭氧反應(yīng)器保持較高的微生物量，并使出水水質(zhì)得到保證。</div>
