【正文】 1 概述 隨著工業(yè)化步伐的不斷加快，廢水污染物的產(chǎn)生量也明顯的增加。廢水經(jīng)過(guò)格柵和曝氣沉砂池去除大部分固體廢物后，進(jìn)入 SBR 反應(yīng)池進(jìn)行生物處理，最后通過(guò)加氯消毒后達(dá)標(biāo)排放。武漢理工大學(xué)畢業(yè)設(shè)計(jì) i 目錄 摘要 ...................................................................................................................................................
