pure water filter
⑵ 求一篇關於純凈水的英語作文
In view of the current observed the advantages and disadvantages of pure water, the researchers put forward three proposals: First, inorganic mineral content and an appropriate degree of pollution-free natural water sources, should be the best choice for human drinking water. In rural areas, such as the wild areas of good water quality, water in the absence of extraordinary modern organic pollutants or toxic pollution microbiology from the security, availability of water to boil or filter drinking can be treated, there is absolutely no need Expensive long-term drinking water. Second, in the city or water in the modern organic heavily polluted areas, clean drinking water can rece the adverse long-term water quality on the body of harmful, However, in order to avoid long-term side effects of drinking when the community should develop standards for mineral water, indivials should increase the food potassium, sodium, magnesium, zinc, copper, iron and other elements of the intake, dietary fat control, so as not to increase the cardiovascular The damage, and pay attention to the prevention of microbial contamination. Third, growing children, pregnant women, high-intensity physical activity group (such as soldiers, athletes, etc.), obesity, cardiovascular disease patients, not long-term clean drinking water.
⑶ 誰有整套純化水制備系統專業術語英文版的啊
1.蒸餾法，按蒸餾器皿可分為玻璃、石英蒸餾器，金屬材質的有銅、不銹鋼和白金蒸餾器等。按蒸餾次數可分為一次、二次和多次蒸餾法。此外，為了去掉一些特出的雜質，還需採取一些特殊的措施。例如預先加入一些高錳酸鉀可除去易氧化物；加入少許磷酸可除去三價鐵；加入少許不揮發酸可製取無氨水等。蒸餾水可以滿足普通分析實驗室的用水要求。由於很難排除二氧化碳的溶入。所以水的電阻率是很低的，達不到MΩ級。不能滿足許多新技術的需要。%D%A %D%A 2.離子交換法，主要有兩種制備方式：%Dª. 復床式，即按陽床—陰床—陽床—陰床—混合床的方式連接並生產去離子水；早期多採用這種方式，便於樹脂再生。%D«. 混床式（2-5級串聯不等），混床去離子的效果好。但再生不方便。%D%A離子交換法可以獲得十幾MΩ的去離子水。但有機物無法去掉，TOC和COD值往往比原水還高。這是因為樹脂不好，或是樹脂的預處理不徹底，樹脂中所含的低聚物、單體、添加劑等沒有除盡，或樹脂不穩定，不斷地釋放出分解產物。這一切都將以TOC或COD指標的形式表現出來。例如，當自來水的COD值為2mg/L時，經過去離子處理得到的去離子水的COD值常在5-10mg/L之間。當然，在使用好樹脂時會得到好結果，否則就無法制備超純水了。 %D%A %D%A 3.電滲析法，產生於1950年[4]，由於其能耗低，常作為離子交換法的前處理步驟。它在外加直流電場作用下，利用陰陽離子交換膜分別選擇性的允許陰陽離子透過，使一部分離子透過離子交換膜遷移到另一部分水中去，從而使一部分水純化，另一部分水濃縮。這就是電滲析的原理。電滲析是常用的脫鹽技術之一。產出水的純度能滿足一寫工業用水的需要。例如,用電阻率為1.6KΩ·cm(25°C)的原水可以獲得1.03MΩ·cm(25°C)的產出水。換言之，原水的總硬度為77mg/L時產出水的總硬度則為∽10mg/L.%D%A %D%A 4.反滲透法，目前它是一種應用最廣的脫鹽技術。反滲透膜雖在1977年 就有了，但其規模化生產和廣泛用於脫鹽卻是近幾年的事情。反滲透膜能去除無機鹽、有機物（分子量>500）、細菌、熱源、病毒、懸濁物（粒徑>0.1μm）等。產出水的電阻率能較原水的電阻率升高近10倍。

Sewage treatment:
According to different levels, sewage sludge sewage treatment can be divided into secondary and tertiary treatment,. Primary treatment basically is in a suspension of solid waste, mainly by the interception and settlement, oil physical method. Second is the main task for the treatment of wastewater is greatly removed the colloid and dissolved organic pollutants, use the method of activated sludge, the biological treatment membrane. 3 processing and depth, its purpose is to remove the suspended, inorganic wastewater and other pollutants, the commonly used method is mainly physical and chemical methods, such as the technology adsorption, ion exchange and coagulation precipitate, oxidation, etc.
Urban sewage by grid, a leaking (tank), remove the suspended and gravel, large and aeration biological treatment into second leaking (second pond) spate separation, separated from the sludge sedimentation of back into aeration, another part of the concentration, the digestion and dehydration after the comprehensive utilization of shipped, 2 the leaking water via chlorination pool after disinfection in-depth processing or discharge.
Water treatment:
The basic principle of water -- > add alum, settling -- > > -- -- - and chlorine
First choose suitable water pipes and pipe, use water pump and pump (1) and before the pump to kill alga, chlorination plants and shellfish. Through the level of water pump to plant processing system. After mixing (usually in source water addition of suitable amount of aluminium, commonly known as "), precipitation, filtration, disinfection process, each process with the corresponding structures (such as filters, QingShuiChi leaking, etc), after disinfection is generally chlorination and ammonia, putting the disinfectant QingShuiChi, and by the water in the pool for an hour or so, the water qualified secondary pump water pump (by) pressure to urban network for drinking and proction.
