East pumps are adopted in this system. East pumps run steady and have little noise. 預 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) ,對原水進行初步凈化,達到后續(xù)設備的進水要求。整臺設備緊湊。反洗時 采用氣水反沖洗。反洗水強度應使濾層膨脹 15~ 25%。 Pretreatment Filters: Fibrous wadding filters use fibrous wadding material as the filtration medium. It can remove bedloads, suspended solids, colloids and part of anics。 airwater backwashing。 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),如果進入膜處理系統(tǒng),會產(chǎn)生細菌滋長,因此需去除此類有機物質(zhì)。其連續(xù)的聚合物相和連續(xù)的孔結構賦予其優(yōu)異的吸附性能,此種樹脂 TOC 的去除率 可達到 90%以上。 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)生細菌滋長的影響,因此在系統(tǒng)中設置了殺菌劑投加裝置,殺菌劑類型為次氯酸鈉。 絮凝劑的投加通過電磁隔膜計量泵投加,流量為 。酸液 的投加通過電磁隔膜計量泵投加,流量為 。 Antiscalant Dosing: within the specific membrane separation system, while fresh water permeates, the dissolved solids including sulfates, carbonates, and silicates will remain in the dense water side where they will condense and will deposit onto the membrane surface, thus altering the membrane performance. A certain amount of 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 16 antiscalants will be added to prevent this phenomenon. A special highperformance antiscalant imported from the . will be used in the system. The antiscalants will be dosed in the system by using a dosing pump equipped with electromagic diaphragm. 冷卻塔 (業(yè)主自備) : 由于 原水水溫為 30~40℃ ,出水要求 20℃, 系統(tǒng)中在進入 纖維球 過濾器之前設置 兩 套 單套 過流水量為 50m3/h 的 冷卻塔。 Ultrafiltration Device: Ultrafiltration technology has been widely applied in the water treatment fields.
