And it is specially designed here according to the raw water quality. It can remove granule, suspended solid, colloid, anic pounds and congregated objects and protect the RO membrane from damage or pollution. Characteristic of **** sand filter are as follows: Effectively remove of suspended solid, colloid, anic pounds from the raw water. ——Particular and symmetrical water distribution ensured the optimization of filter efficiency to make sure the outlet water SDI meet RO inlet water requirement. 10t/h 脫鹽水系統(tǒng) 20 ——Low flow velocity will be introduced according to the character of surface water. ——Long period of operation. ——The sand filter is specially designed for RO pretreatment system. Choice quartz sand makes a good filtration and against from layerdisorder when backwashing. Multiway valve control shall control the sand filter. And the backwash period will be controlled by time. When running time of the sand filter has reached the set time, it will be stop. Multiway valve will open the backwash waterway and take backwash procedure automatically. The sand filter will enter work state automatically after the backwash. 砂過濾器是反滲透系統(tǒng)重要的預(yù)處理裝置，本系統(tǒng)采用專門針對用戶原水水質(zhì)特點而設(shè)計的砂過濾器，它的作用是濾除原水中的細(xì)小顆粒、懸浮物、膠體、有機(jī)物等雜質(zhì)，以及經(jīng)加藥后形成的大顆粒，從而起到保護(hù)反滲透的作用 . 特點： ——能夠有效地去除原水中的膠體、懸浮物及有機(jī)物等。 殺菌劑加藥系統(tǒng)的作用是防止微生物生長。 由于系統(tǒng)進(jìn)水受到有機(jī)物污染，水中的其他雜質(zhì)如懸浮物、膠體等往往帶有一定量的同性電荷，它們相互排斥，難以自動聚集成大顆粒。 (3) Dosing system 加藥系統(tǒng) The system is equipmented with coagulant dosing and bactericide dosing system here. 10t/h 脫鹽水系統(tǒng) 16 Through coagulant dosing system, coagulants will add into the raw water to congregate the suspended solid, anic pound, colloid, etc to prove filtration efficiency. The impurity such as suspended solid, colloid generally be of homo electric charge, which made them exclude each other and hard to congregate. coagulant is kind of long chain macromolecule. It can neutralize the doubleelectric layer of colloid and counteract heterogeneous group as well as adsorb the suspended solid, anic pound, colloid and congregate them to big objects and then removed by sand filter. Bactericide dosing system is used to prevent the growth of animalcule. 加藥系統(tǒng)分為 混 凝劑加藥系統(tǒng)與殺菌劑加藥系統(tǒng)。 本系統(tǒng)采用 2 臺立式離心泵。根據(jù)招標(biāo)書要求，原水箱容積為 15m3，材質(zhì)為 PE， 為了便于控制，原水箱配液位開關(guān)。 預(yù)處理系統(tǒng)的處理對象主要是進(jìn)水中的機(jī)械雜質(zhì)、膠體、鐵、微生物、藻類、有機(jī)物等。 為了保證反滲透系統(tǒng)正常運(yùn)行，需定期對預(yù)處理系統(tǒng)出水水質(zhì)進(jìn)行檢測，檢測水樣從碳濾器產(chǎn)水總管采集，采用人工檢測，檢測頻率初定為一天兩次，主要檢測指標(biāo)為 SDI值。 wayer balancechart 系統(tǒng)水量平衡圖（見下頁） RW: raw water RWT: raw water tank SF: sand filter ACF: active carbon filter IT: intermedia tank 1st:1st RO 10t/h 脫鹽水系統(tǒng) 10 2nd:2nd RO DIT: DI water tank CR: concentration return BD: backwash drain CD: concentration drain Process flow chart 工藝流程圖 Abbreviation: RW: raw water RWT: raw water tank RP: raw water pump BC: bactericide PM: pipe mixer SF: sand filter ACF: active carbon filter 1t/h RW 原水 SF 砂 過濾器 1st PassRO 一級 RO RWT 原水池 CD 濃排水 Tank 脫鹽水 箱 BD 反洗水 Tank 中間水池 ACF 活性炭過濾器 11t/h 10t/h CR 濃水回流 2nd Pass RO 二 級 RO BD 反洗水 10t/h 脫鹽水系統(tǒng) 11 BS: backwash system IT: intermedia tank 1st ROP:1st Pass RO supply pump SI: scaling inhibitor 1st ROSF: 1st Pass RO security filter CR: concentration return 1stROHP: 1st Pass RO high pressure pump CD: concentration drain CC: chemical cleaning 1st RO: 1st Pass RO set 2nd ROHP: 2nd Pass RO high pressure pump 2nd RO: 2nd Pass RO set DIT: DI water tank DISP: DI water booster pump PU: point of use Specification: Sand Filter system include: Sand Filter, backwash system, control instrument, etc. Active carbon Filter system include: Active carbon Filter, backwash system, control instrument, etc. RO system include: RO protective filter， highpressure pump, RO units, RO cleaning system, control instrument, etc. 過濾器系統(tǒng)包括：砂過濾器、砂過濾器反洗系統(tǒng)、控制儀表等； 活性炭過濾器系統(tǒng)包括：活性炭過濾器、活性炭過濾器反沖洗系統(tǒng)、控制儀表等； 反滲透系統(tǒng)包括：保安過 濾器、高壓泵、反滲透膜組、反滲透清洗系統(tǒng)和控二級反滲透產(chǎn)水箱 二級反滲透產(chǎn)水箱 10t/h 脫鹽水系統(tǒng) 12 制儀表等。反滲透可降低水的含鹽量和電導(dǎo)率，使出水水質(zhì)符合要求。 由于，反滲透是比較精密的水處理系統(tǒng)，原水只有經(jīng)過合理、可靠的預(yù)處理，才能不對反滲透系統(tǒng)造 成污染或?qū)⑽廴境潭冉档阶畹?，從而很好的保護(hù)了核心除鹽系統(tǒng)，延長反滲透膜的使用壽命，大大降低運(yùn)行成本和維護(hù)成本，因此，為本系統(tǒng)配置先進(jìn)、可靠的預(yù)處理工藝：砂過濾器＋活性炭過濾器。 proposal design idea 方案設(shè)計思路 The treatment process, sand filter amp。依據(jù)業(yè)主提供水質(zhì)報告及業(yè)主對本系統(tǒng)的要求，本系統(tǒng)采用我公司設(shè)計制造的砂過濾器 +活性炭過濾器作為預(yù)處理設(shè)備，設(shè)備運(yùn)行穩(wěn)定，抗沖擊負(fù)荷 能力強(qiáng)，除鹽采用穩(wěn)定、可靠的反滲透技術(shù)，技術(shù)先進(jìn)可靠，保證了產(chǎn)水質(zhì)量。 本系統(tǒng)根據(jù)進(jìn)水水質(zhì)及出水要求進(jìn)行專門設(shè)計。 Pressure Parts （ 1） GB150 （ 2） ASME （ 3） Supervision regulation on safety technology for pressure vessel Materials （ 1） ASTM （ 2） ASME （ 3） Chinese Standard Piping/Flange （ 1） HG 2055393 (Pipes) （ 2） HG 20592~20635 (Flange, bolts, nuts, gaskets, etc) 制造及材料應(yīng)符合下列標(biāo)準(zhǔn)和規(guī)程的最新版本的要求。S/cm （ max） Appearance 表觀： clear colorless liquid 無色 Oxidizable matter 可氧化物質(zhì) mg/L Residue 蒸發(fā)殘渣 2mg/L. 10t/h 脫鹽水系統(tǒng)
