上期在污水處理技術(shù)篇為大家詳細(xì)解釋了COD,今天為大家詳細(xì)介紹BOD,更多精彩,。BOD(BiochemicalOxygenDemand的簡(jiǎn)寫):生化需氧量或生化耗氧量(一般指五日生化學(xué)需氧量),表示水中有機(jī)物等需氧污染物質(zhì)含量的一個(gè)綜合指示。說明水中有機(jī)物由于微生物的生化作用進(jìn)行氧化分解,使之無機(jī)化或氣體化時(shí)所消耗水中溶解氧的總數(shù)量。解氧瓶中,在2℃的暗處培養(yǎng)5d,分別測(cè)定培養(yǎng)前后水樣中溶解氧的質(zhì)量濃度,由培養(yǎng)前后溶解氧的質(zhì)量濃度之差,計(jì)算每升樣品消耗的溶解氧量,以BOD5形式表示。

·集成化:建立一個(gè)集成了多技術(shù)的系統(tǒng)平臺(tái),包括順序控制、運(yùn)動(dòng)控制、傳動(dòng)控制和過程應(yīng)用。威強(qiáng)應(yīng)用Inbbb?Core?2Duo處理器的經(jīng)典突破
兩種方法各有千秋,其制約因素是成本和、廉價(jià)催化劑、酶和合適微生物的開發(fā)等關(guān)鍵技術(shù)。總而言之,生物法具有選擇性、活性好、反應(yīng)條件溫和等優(yōu)點(diǎn),但原料利用率低、反應(yīng)時(shí)間長(zhǎng)、產(chǎn)物濃度低及酶、微生物活性易受影響且纖維素降解和單糖轉(zhuǎn)化所需酶、微生物適于不同反應(yīng)條件,不能很好耦合。相比,化學(xué)法具有原料利用率高、反應(yīng)時(shí)間短、催化劑構(gòu)成簡(jiǎn)單、沒有嚴(yán)格反應(yīng)條件限制等優(yōu)點(diǎn),但為高溫、高壓過程,對(duì)設(shè)備要求高。效分析生物質(zhì)直接燃燒熱效率很低,只有1%左右,而將它們轉(zhuǎn)化成氣體或液體燃料(甲烷、氫氣、乙醇、丁醇、柴油等)熱效率可達(dá)3%以上,緩解了人類面臨的資源、能源、環(huán)境等一系列問題。
