1、曝氣生物濾池處理城鎮(zhèn)污水論文學(xué)位論文曝氣生物濾池處理城鎮(zhèn)污水這是本人畢業(yè)時(shí)所寫論文,希望有和我寫同樣題目的朋友,能通過大學(xué)論文答辯。如果你感覺這篇論文不錯(cuò),那請你給我頂一下,在這里感謝大家。作者姓名:專業(yè):學(xué)號(hào):指導(dǎo)教師:完成日期:學(xué)校名-I-曝氣生物濾池處理城鎮(zhèn)污水摘要城鎮(zhèn)污水主要為生活污水和工業(yè)廢水的混合污水。目前城鎮(zhèn)污水的排放已造成了對水環(huán)境生態(tài)系統(tǒng)的嚴(yán)重污染,做好城鎮(zhèn)污水的處理及再生利用是主要任務(wù)之一,解決城鎮(zhèn)污水對水環(huán)境污染的重要途徑之一就是修建污水處理廠。本設(shè)計(jì)對SBR法、A2/O法、曝氣生物濾池法工藝進(jìn)行了比較,最終確定選用處理效果好、運(yùn)行管理方便、投資省的曝氣生物濾池工藝。
2、該工藝中污水經(jīng)過粗格柵、細(xì)格柵、旋流沉砂池、水解酸化池的一級(jí)處理,進(jìn)入曝氣生物濾池進(jìn)行二級(jí)處理后。排出的污泥經(jīng)過了生化處理較穩(wěn)定,不需消化濃縮脫水外運(yùn),節(jié)省了投資。設(shè)計(jì)過程中通過對各構(gòu)筑物的設(shè)計(jì)計(jì)算及附屬構(gòu)(建)筑物的設(shè)計(jì)選型,完成了主要構(gòu)筑物旋流沉砂池、水解酸化池、曝氣生物濾池出圖及整個(gè)工廠的平面、高程布置,進(jìn)而完成了污水廠的設(shè)計(jì)。關(guān)鍵詞:城鎮(zhèn)污水;水解酸化;上向流曝氣生物濾池-II-TheFormatCriterionofMaster’sDegreePaperofDUTAbstractUrbansewageasthemainsewageandindustrialeffluentofse
