上海市政院鄒偉國等開發(fā)了一種名為BIOSMEDI的曝氣生物濾池，它采用脈沖反沖洗、氣水同向流的形式，可用于微污染源水預(yù)處理或污水深度處理。BIOSMEDI生物濾池是上海市政工程設(shè)計研究院針對微污染原水開發(fā)的一種新型生物濾池，該濾池以輕質(zhì)顆粒濾料為過濾介質(zhì)，濾料比重較小，一般約在0.1左右，粒徑的大小為4～5mm左右，比重及粒徑的大小可根據(jù)實際需要選擇確定，這種濾料具有來源范圍廣、濾料比表面積大、表面適宜微生物生長、價格便宜（300～500元/立方米）、化學(xué)穩(wěn)定性好等一系列優(yōu)點。 </p><p style="text-indent:25px">問題前景作為一種嶄新的水處理工藝——曝氣生物濾池正處在推廣之中。根據(jù)研究和應(yīng)用情況，今后仍有很多問題有待研究：生物膜的特點及其快速啟動的方式；生物氧化功能和過濾功能之間的相互關(guān)系；反沖洗過程中生物膜的脫落規(guī)律；進(jìn)一步拓寬曝氣生物濾池的應(yīng)用范圍，研究其在水深度處理、微污染源水處理、難降解有機物處理、低溫污水的硝化、低溫微污染水處理問題中如何與其他工藝相結(jié)合。曝氣生物濾池中中心介質(zhì)――濾料的研究也會促進(jìn)該工藝在中國的應(yīng)用的范圍，BIOSTYR、Biofor兩種工藝功能比較強大，但在中國大范圍的應(yīng)用仍存在問題，如**問題，再有它們從投資上都比較大，這也阻礙了這兩種工藝在中國的大范圍的應(yīng)用。所以特種濾料的的研究與生產(chǎn)的國產(chǎn)化將是曝氣生物濾池在國內(nèi)大范圍的應(yīng)用的關(guān)鍵。BIOSMEDI生物濾池原理：濾池上部采用鋼筋混凝土板抵一一制濾料的浮力及運行的阻力。</p><div

低負(fù)荷型生物濾池低負(fù)荷型生物濾池是一種結(jié)構(gòu)簡單、運行可靠的裝置，其出水水質(zhì)與進(jìn)水水質(zhì)濃度無較大關(guān)系。濾池的池型多為圓形或者矩形。一般采用吸水高度可控的水泵或者虹吸式投配箱維持調(diào)節(jié)池的配水量。投配池的容積很小，只有2分鐘的停留時間，所以投配時間間隔很短。在小型廢水處理廠中，夜間的低流量現(xiàn)象仍有可能是投配中斷造成的，為此，為了使填料保持濕潤，可能需要將出水循環(huán)回流。如果投配時間間隔大于1-2h，會導(dǎo)致生物膜表面濕度不夠，生物黏泥的特性也會隨著改變，結(jié)果濾池的處理效率下降。在大多數(shù)的低負(fù)荷濾池內(nèi)，生物黏泥只在濾池填料頂部0.6-1.2m處明顯存在，所以在濾池的較低部位可使氨氮氧化成亞硝酸鹽和硝酸鹽的自養(yǎng)型硝化細(xì)菌的可能性增大。在適宜的氣候條件和廢水特性條件，硝化細(xì)菌會大量繁殖，運行穩(wěn)定的低負(fù)荷濾池不但能很好的去除BOD，而且還能夠很好的將水中的氨氮轉(zhuǎn)化成硝酸鹽。在合適的落差梯度下，采用重力流較好，如果場地比較平坦，則需要泵提升。生物濾池容易產(chǎn)生臭氣對環(huán)境造成二次污染，特別是如果廢水滯留較舊腐化嚴(yán)重，或者氣溫較高時尤甚，如果不采取有效的防治措施，濾池內(nèi)很容易滋生蚊蠅。曝氣生物濾池工藝特點 ③進(jìn)水要求懸浮物50～60mg/L，與一級強化處理相結(jié)合比較好，如采用水解酸化池；二七區(qū)虹吸濾池</p><p style="text-indent:25px">目前實際應(yīng)用中，大部分是快濾池?？鞛V池處理能力較大，出水水質(zhì)好。二七區(qū)虹吸濾池</p><p style="text-indent:25px">Biofor工藝Biofor（生物過濾氧化反應(yīng)池）是得利滿水務(wù)繼滴濾池、Biodrof干式過濾系統(tǒng)之后的專為污水處理廠設(shè)計的第三代的生物膜反應(yīng)池。與其它類型的生物過濾工藝相比，Biofor主要具有下列特性：①向上流生物過濾進(jìn)水自濾池底部流向頂部，上流過濾在濾池的整個高度上持續(xù)提供正壓條件，與下向流過濾相比提供了許多優(yōu)勢。②使用特制的過濾及生物膜支持煤介：Biolite生物濾料確保獲得較高的生物膜濃度和較大的截留能力，并加長了運行周期。③高性能曝氣Biofor采用了特制的曝氣頭：它不僅能有效的供氧，而且節(jié)約能源、使用安全、易于操作和維護(hù)。④流體完全均勻的分布空氣和水流為同向流。Biofor生物濾池的濾板配有25UB33e濾頭，該濾頭的防阻塞設(shè)計通過均勻的配水使過濾效果優(yōu)化。二七區(qū)虹吸濾池</p></p><br
