ssing technology and the emission standard. The process can be summarized as follows: Firstly, primary treatment was carried out to remove most of the suspended solids and the main structures include grille, pool and airconditioning pool. And then hydrolysis acidification and contact oxidation pond were used as biological treatment. Refractory anic matter was degraded into mall molecule anic pound through the role of hydrolysis, and then was oxidized into CO2 and biomass. The hydrolytic acidification—contact oxidation process was beneficia to lessen load, increase anic matter removal and reduce sludge volume. Treated water can reach the firstlevel emission standard of Integrated Wastewater Discharge Standard (GB89781996). In this paper, the calculation of main structures, the preparation of design manuals, and five blueprints including district layout , flow chart, elevation chart , main structures were acplished. Keywords: aeration。 處理后的出水能達到 國家 《 污水綜合排放標準 》 ( GB89781996)的一級排放標準。 繼而進行生化處理,主要構(gòu)筑物為水解酸化和接觸氧化池,廢水中的難降解有機物通過水解酸 化變?yōu)橐捉到獾?,小分子有機物,再通過好氧處理變?yōu)?CO2 和生物質(zhì)。 針對 其 廢水特點,考慮成本 、 處理技術 、 進出水水質(zhì)等因素, 最終確定水解酸化 — 接觸氧化 的處理工藝。 XXXX 乳業(yè)污水處理 廠 工藝設計 目 錄 引 言 ........................................................................................................................................... 3 1 設計說明書 ............................................................................................................................... 8 設計任務 ........................................................................................................................... 8 流程說明 ........................................................................................................................... 8 2 污水處理設計 .......................................................................................................................... 9 中格柵 ............................................................................................................................... 9 調(diào)節(jié)池 ..............................................................................................................................11 氣浮池 ............................................................................................................................. 12 水解酸化池 ..................................................................................................................... 15 接 觸氧化池 ..................................................................................................................... 17 二沉池 ............................................................................................................................. 19 3 污泥部分的計算 ................................................................................................................... 24 集泥井 ............................................................................................................................. 24 污泥濃縮池 ..................................................................................................................... 25 污泥脫水 ........................................................................................................................ 27 4 高程的計算 ............................................................................................................................ 28 高程布置原則 ................................................................................................................. 28 水頭損失 ......................................................................................................................... 28 高程計算 ......................................................................................................................... 29 5 泵的選型 ................................................................................................................................. 32 6 工程概算及效益分析 .......................................................................................................... 33 工程初步投資預算 ......................................................................................................... 33 經(jīng)濟效益分析 ................................................................................................................. 33 環(huán)境效益分析 ................................................................................................................ 34 結(jié) 論 .................................................................................................................................... 35 致 謝 .................................................................................................................................. 36 參 考 文 獻 ............................................................................................................................. 37 No 1 摘 要 本文是 乳業(yè)污水的 處理工藝 設計, 以解決 其廢水 帶來的環(huán)境污染問題 。 奶制品工業(yè)廢水 具有 污染物濃度較高,易生化降解,懸浮物含量高 等 的特點 。 流程簡述為: 首先對污水進行一級處理,主要 構(gòu)筑物 有格柵,調(diào)節(jié)池 和氣浮池,目的是去除大部分的懸浮物 。 這種 缺 氧 好氧 聯(lián)合 的方法 對減輕好氧生物處理負荷、提高有機物去除率、降低污泥量極為有利。 本文對 主要構(gòu)筑物 進行計算,編制設計說明書 ,并繪制 工藝流程、構(gòu)筑物 平面及 高程、 主要構(gòu)筑物共五張圖紙 。 sedimentation。生產(chǎn)過程中排出的水。 食品工業(yè)原料廣泛,制品種類繁多,排出廢水的水量、水質(zhì)差異很大。食品工業(yè)廢水的特點是有機物質(zhì)和懸浮物
