Operation: manual and automatic, autoprotection. Water supply: 24 hours. 工藝設(shè)備說明 Introduction about the Facilities： 原水箱： 用于貯存進(jìn)入本系統(tǒng)的原水，其目的是為了調(diào)節(jié)進(jìn)水流量的變化，防止進(jìn)水波動對系統(tǒng)運行產(chǎn)生影響，保證系統(tǒng)的進(jìn)水量穩(wěn)定。 Feed Water Lifting Pumps: used to provide steady hydraulic pressure and flux for following facilities. East pumps are adopted in this system. East pumps run steady and have little noise. 預(yù) 處理 過濾器： 纖維球 過濾器 （ FWF） 主要利用 纖維球作為濾料 ，去除原水中的泥沙、懸浮物、膠體、 油類 等雜質(zhì) ，對原水進(jìn)行初步凈化，達(dá)到后續(xù)設(shè)備的進(jìn)水要求。反洗時 采用氣水反沖洗。 Pretreatment Filters: Fibrous wadding filters use fibrous wadding material as the filtration medium. It can remove bedloads, suspended solids, colloids and part of anics。 因原水中含有一定量的揮發(fā)酚、石油類以及其他有機物質(zhì)，如果進(jìn)入膜處理系統(tǒng)，會產(chǎn)生細(xì)菌滋長，因此需去除此類有機物質(zhì)。 Fibrous wadding filter effluent flows into the special resin adsorption column. The raw water contains a certain amount of volatile phenol, petroleum and other anic substances, and if they go into membrane systems, it will bring about the growth of bacteria. Therefore, it is needed to remove these anic substances. Adsorption resin is a kind of anic polymer adsorbent nonsoluble into acid, alkali and various anic solvents. The application of macroporous adsorption resin 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 14 is one of new separation technologies after ion exchange resins. The pore size and surface area of macroporous resin is large, and has a threedimensional space within pore structure, with the stability physical chemical and high specific surface area, large adsorption capacity, efficiency selectivity, fast absorption and desorption under mild conditions, facilitated regeneration, the use of a long cycle and savings, and many other advantages. The wastewater treatment system selects the RohmHaas special adsorption resin. It is a kind of nonpolar polymeric adsorbent with high degree of crosslinked, high specific surface area, no functional groups, and it is stability and has long service life. Its continuous polymer phase and a continuous pore structure give it excellent adsorption properties. TOC removal rate can reach 96%. Adsorption system will go through the eluting after adsorption saturation, and TOC elution rate can reach 99%, so the system can ensure the anic removal effects and normal operation. When remnants concentration in the outflow of exchange column exceeds the targets, the resin is saturated, and it is needed for regeneration to creating conditions for next exchange process. After resin regeneration, remaining regeneration agent in the resin layer should be washed using the product water. 加殺菌劑： 系統(tǒng)中考慮水源水為經(jīng) 前 處理的 污 水，水中微生物的生長將對系統(tǒng)的運行產(chǎn)生細(xì)菌滋長的影響，因此在系統(tǒng)中設(shè)置了殺菌劑投加裝置，殺菌劑類型為次氯酸鈉。酸液 的投加通過電磁隔膜計量泵投加，流量為 。 Ultrafiltration Device: Ultrafiltration technology has been widely applied in the water treatment fields. It can purify water by removing particulates, colloids, bacteria, virus, heat energy resource, protein and large anic molecules from the water medium. Materials for the ultrafiltration membrane include the PS, PES, PP, PVDF. 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 17 超濾裝置示意圖 Ultrafiltration Device 工藝描述 ： 過濾 AquaFlexPTM組件由 PVC 外筒和中心出水管，以及中空纖維膜絲組成，膜絲材料為聚醚砜和聚乙烯吡咯酮共混材料。過濾過程的 TMP 不能超過 1bar超過 1bar 的過濾壓降，會導(dǎo)致在膜的表面形成無法反洗掉的污垢。反洗過程中 TMP，并非唯一重要指標(biāo)。正沖通量為過濾通量，正沖時間為 530 秒，氣正沖時間為 10s，氣量為每支膜 10Nm3P/h。整個 CEB 過程中， TMP 不能超過 3bar，膜通量為 。 超濾系統(tǒng)由 PLC 可編程控制系統(tǒng)實現(xiàn)集中控制，超濾膜反洗、正沖與運行可人工通過控制柜實現(xiàn)人工操作或自動操作 ，人工操作時，只需按下控制面板上的步操按鈕，系統(tǒng)可進(jìn)行各個執(zhí)行步聚，狀態(tài)切換通過氣動 /電動碟閥來實現(xiàn)。 保安過濾器： 為了保證特種分離膜元件不被懸浮物顆粒所傷害，系統(tǒng)設(shè)置保安過濾器，過濾精度為 5μm，內(nèi)裝聚丙烯濾芯，外殼為不銹鋼結(jié)構(gòu)。 Model Selection of Specific Membrane System: the specific membrane device is posed of highpressure pump, rack, specific membranes and highpressure membrane tube, and is equipped with the flow
