【正文】 7 四、 Design amp。 proposal design idea 方案設(shè)計(jì)思路 The treatment process, sand filter amp。 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。 (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)。 ——采用較低的運(yùn)行流速,以適應(yīng)地表水的特點(diǎn)。 總體過濾面積: 178。 filtrate flow velocity: filtrate flux of unit: quantity: 1sets multiway valve: 1set installation form: Top entry 活性炭濾器系統(tǒng)參數(shù) 過濾系統(tǒng)型號: Ф900H1800mm 材質(zhì): FRP 單元過濾面積: 178。 一級 RO 供水泵參數(shù)如下: 流量: 揚(yáng)程: 30m 功率: 3KW 10t/h 脫鹽水系統(tǒng) 26 材質(zhì): SS304 數(shù)量: 2 臺 ( 1 用 1 備) ( 2) Scale inhibitor dosing set 阻垢劑加藥裝置 To avoid the chemical scaling of RO concentrated water side especially the last one membrane element bring by high recovery rate, scale inhibitor will be added into the water before feeding to RO set to protect the membrane from performance infection. BWA high efficiency scale inhibitor is used in this system. As a king of dispersant masking agent, it has the points as follows: ★ High scaling efficiency: It can keep the system from scaling within LSI value (maximum allowable value) without acid. ★ The main ponent small phosphorus anic pounds are chemical steady in water, and won’t change into nutrimental phosphate. The drain won’t bring pollution to the environment. ★ With the excellent dispersion property, iron, aluminum and heavy metal pollution will be controlled and iron colloid and granule will be dispersed. 為了在較高回收率情況下防止反滲透濃水端特別是反 滲透壓力容器中最后一根膜元件的濃水側(cè)出現(xiàn)碳酸鹽、硫酸鹽和 Ca2+、 Mg2+離子的化學(xué)結(jié)垢,從而影響膜元件的性能,在反滲透進(jìn)水前需要加入阻垢劑。 1st pass RO Security Filter Parameter: Flux: Vessel size: Ф2501200mm material: SS304 quantities: 1set Filter core: 40’PP meltblown Filtration precision: 5um Quantities Of Filter core: 5 each set 一級 RO 保安過濾器參數(shù): 過濾水量: 罐體尺寸: Ф2501200mm 材質(zhì): SS304 數(shù)量: 1 臺 10t/h 脫鹽水系統(tǒng) 29 濾芯: 40’PP 熔噴濾芯 過濾精度: 5μ m 濾芯數(shù)量 : 8 支 /臺 ( 4) High Pressure Pump 高壓泵 High pressure pump shall pressurize the inlet water to an adequate station to maintain RO running. 1st pass RO high pressure pump parameter: Flux: Lift: 90m Power: Material: Flow passage ponents SS316 quantities: 1set 2nd pass RO high pressure pump parameter: Flux: 11t/h Lift: 70m Power: Materials: Flow passage ponents SS316 Quantities: 1set 高壓泵為反滲透膜組提供足夠的進(jìn)水壓力,維持反滲透膜的正常運(yùn)行。 ★ 主要成分為含磷小分子有機(jī)物,在水中性質(zhì)穩(wěn)定,不易分解產(chǎn)生具有微生物營養(yǎng)的正磷酸鹽營養(yǎng)物,排放后也不會對環(huán)境產(chǎn)生污染。 10t/h 脫鹽水系統(tǒng) 23 過濾流速: 單元過濾流量: 數(shù)量: 1 臺 多路閥: 1 臺 安裝形式:頂裝 ( 6) Intermediate storage tank 中間水箱 The filtered water will be collected in the middle tank as the supply of the following treatments.
