【正文】 好相反。將污物運出毛細管的速度同樣為重要指標，推薦反洗的膜通量為 250300L/。干凈的過濾出水，在壓力作用下，從毛細管膜的外部向內部沖洗，從而將污垢帶出毛細管膜。 根據(jù)進水水質和使用的膜的種類不同，間歇過濾的時間為 1060 分鐘。過濾過程的驅動力來自進水（進入毛細管）和出水（出毛細管）之間的壓力差，即所謂的過濾壓降（ TMP）。中空纖維膜絲由 23cm的環(huán)氧樹脂密封在 PVC 外筒中，原水從毛細管的內部進入。冷卻塔 的主要作用在于通過換熱以 降低 出水的水溫， 并 為后續(xù)膜系統(tǒng)裝置提供穩(wěn)定的水溫，保持相對穩(wěn)定的產水通量。 Acid Dosing: Aciddosing system for pH adjusting can effectively prevent deposit problems in the surface of specific separation membrane ponents. Acid will be dosed at a rate of electromagic diaphragm. 加阻垢劑： 系統(tǒng)采用加入一定量的阻垢劑，防止 特種分離 膜元件在選擇透過淡水的同時，其 濃水側的溶解固形物如：硫酸鹽、碳酸鹽、二氧化硅等因為濃縮而在 特種分離 膜表面結垢，影響膜的性能。 Flocculants Dosing: A certain amount of flocculants will be added before the 山東三維石化工程股份有限公司 100T/H 污水回用系統(tǒng)方案書 Scheme of 100T/H Sewage Recovery System for Shandong SunWay Petrochemical Engineering Co., Ltd 上海瑞璋環(huán)境工程有限公司 Razan Environment Engineering (Shanghai) Co.,Ltd 15 filter system to allow the filter padding to block suspended solids and colloids in water through charge neutralization and bridging adsorption. These suspended solids and colloids will then be discharged through backwashing. By doing so, pollution and congestion will be effectively prevented in the specific membrane separation system. Flocculants are dosed by electromagic diaphragm dosing pump, and the dosage is 加還原劑： 系統(tǒng)中由于在 纖維球 過濾器之前設置了次氯酸鈉投加，由于次氯酸鈉為氧化性物質，因此經 纖維球 過濾器的出水需要投加還原劑進行還原，還原劑類型為亞硫酸氫鈉。 殺菌劑的投加通 過電磁隔膜計量泵投加，流量為 。吸附系統(tǒng)吸附飽和后再經過洗脫液洗脫， TOC 的洗脫率可達到 99%，因此能夠保障樹脂吸附系統(tǒng)的去除效果和正常運行。 吸附樹脂是一種不溶于酸、堿及各種有機溶劑的有機高分子聚合物吸附劑，應用大孔吸附 樹脂進行分離的技術是繼離子交換樹脂后的分離新技術之一。 backwashing。 the feed SDI is also reduced and thus the feed water can meet the requirements for the following facilities. After a certain working period, the pressure gap of the wadding filters will increase, and the filters should be backwashed to regain better working efficiency for the fibrous wadding filters. Backwashing periods last 3 to 7 days. Backwashing process: loosing。反洗時送入壓縮空氣，擦洗濾料，其強度為 18～ 25L/s?m2。 將 濾料表面粘附的 泥球雜志 打散并 剝落下來，然后用水沖走， 提高過濾器的反洗效果。占地面積小。多介質過濾器選擇較低的運行濾速，以降低進水的濁度并保證過濾出水污染指數(shù)SDI15≤4。 Concentrated Liquor Collecting Tank (Owner or Razan provides): It is used to collect concentrated liquor from specific membrane separation system. This part of concentrated liquor can be used to wash the fibrous wadding filters. The volume of concentrated liquor tank will be about 100m3. 預處理反洗水泵： 為過濾器反洗提供所需要穩(wěn)定的水壓和流量。 原水箱設置液位控制裝置，可隨時監(jiān)測水箱液位和控制原水泵。 系統(tǒng)配置 ：預處理 50m3/hr2 套 ， 超濾裝置 45m3/hr2 套，特種分離膜主機 30m3/hr2 套 。 The feed water is first pumped into the fibrous wadding filter, then through the special resin adsorption column, and then into the ultrafiltration device. Antiscalant is dosed into water flow after ultrafiltration to avoid precipitation and formation of deposits so that pretreated water can meet the specific membrane separation system requirements. Afterwards, the water is pumped into the specific membrane separation system to remove salt, so that the water produced can meet the design requirements. 系統(tǒng)工藝流程 Process Flow： 原水 → 冷卻塔 → 原水增壓泵 → 絮凝劑 加藥 → 纖維球 過濾器 → 還原劑 加藥 → 特種 樹脂吸附柱 → 超濾裝置 → 超濾 產水儲槽 → 酸液 /阻垢劑 加藥 → 特種分離膜 高壓泵 → 保安過濾器 → 特種分離膜 主機 → 純 水 儲槽 → 純 水泵 → 主廠房用水點 Feed Water → Cooling Tower→ Lifting Pump → Fungicide/flocculants Dosing → Fibrous Wadding Filter→ Reducing Agents Dosing→ Special Resin Adsorption Column→ UF → UF Water Tank → Antiscalant Dosing → Highpressure Pump→ Ensuring Filter → Specific Separation Membrane System→ Pure Water Tank→ Pure Water Pump→ Water Reusing 系統(tǒng)參數(shù) System Parameters： 產水用途 ： 污水處理回用。 The system quality level requested by the owner. 原水水質資料和技術指標 ： 用戶提供的原水供水量充足，水質較為穩(wěn)定，原水水樣水質分析報告 (見前頁 )。 Design basis of this project are as follows: Feed water quality data。 除鹽水輸送 ： 由乙方提供輸送泵及界區(qū)內的配管。 ※ HG2150192《襯膠鋼管和管件》 ※ HG2053892《襯塑（ PP、 PE、 PVC）鋼管和管件》 控制設備、測量儀表和電氣設備的設計、制造應符合下列規(guī)定和標準要求，但不僅限于此。 K mg/1 107 12 鈣 / Ca mg/1 13 鎂 / Mg mg/1 14 硫酸鈉 / Na2SO4 mg/1 15 礦物 / Mineral mg/1 812 16 水溫 / Temperature 0C 30～ 40 、系統(tǒng)產水指標 Effluent Quality： 序號 No. 水質項目 Parameter 單位 Unit 水質指標 Water Quality Standard 1 PH \ 6～ 9 2 色度 / Chromium \ ≤ 15 3 濁度 / NTU mg/1 ≤ 5 4 BOD5 mg/1 ≤ 3 5 CODcr mg/1 ≤ 10 6 石油類 / Oil mg/1 ≤ 1 7 揮發(fā)酚 Volatile Hydroxybenzene mg/1 ≤ 8 NH3N mg/1 ≤ 10 山東三維石化工程股份有限公司 100T/H 污水回用系統(tǒng)方案書 Scheme of 100T/H Sewage Recovery System for Shandong SunWay Petrochemical Engineering Co., Ltd 上海瑞璋環(huán)境工程有限公司 Razan Environment Engineering (Shanghai) Co.,Ltd 7 9 溶解性總固體 /TSS mg/1 ≤ 800 10 總堿度（以 CaCO3 計） Alkalinity(as CaCO3) mg/1 ≤ 350 11 總磷（以 P 計） / TP mg/1 ≤ 1 12 總硬度（以 CaCO3 計） Total hardness(as CaCO3) mg/1 ≤ 400 13 水溫 / Temperature 0C 20 、規(guī)定和標準 Regulations and Standards： 進口設備的制造工藝和材料，符合美國機械工程師協(xié)會（ ASME）和美國材料試驗學會（ ASTM）工業(yè)法規(guī)涉及的標準和相當標準。 、自動化控制設備以及主要檢測儀器、儀表選用國外先進產品或國內知名品牌。 Shandong SunWay Petrochemical Engineering Co., Ltd, plans for a sewage treatment project.
