隨著高層建筑規(guī)模的不斷擴大，二次供水北京ZM-1水箱消毒機器在城市供水中所占的比例也越來越大。本月起，新修訂的《天津市二次供水北京ZM-1水箱消毒機器工程技術(shù)標(biāo)準(zhǔn)》正式實施，至此6層以上提供二次供水北京ZM-1水箱消毒機器的“一刀切”標(biāo)準(zhǔn)被*改變。
據(jù)了解，過去只為6層以上提供二次供水北京ZM-1水箱消毒機器的做法，容易使靠近水廠或水壓大的地區(qū)水量過大，從而造成浪費。而距水廠較遠(yuǎn)或水壓不足的地區(qū)水量過小。根據(jù)新標(biāo)準(zhǔn)，今后居民樓是否必須配備二次供水北京ZM-1水箱消毒機器設(shè)施，不再以6層為界，而是本著因地制宜與節(jié)約用水的原則，根據(jù)建筑物所在區(qū)域市政供水管網(wǎng)的供水狀況等情況確定。“新標(biāo)準(zhǔn)對于普遍用戶而言，二次供水北京ZM-1水箱消毒機器的起始樓層降低了，如果水壓不足、水量不夠，今后6層以下的用戶也能享受二次供水北京ZM-1水箱消毒機器。”市供水處有關(guān)負(fù)責(zé)人表示。對于建筑物所處區(qū)域的特殊性（如處在水廠附近或山區(qū)），可因地制宜根據(jù)市政供水管網(wǎng)的實際供水狀況確定，在保證大原則不變的情況下靈活掌握。
新標(biāo)準(zhǔn)明確規(guī)定，二次供水北京ZM-1水箱消毒機器設(shè)施不應(yīng)對水質(zhì)產(chǎn)生污染，必須采取有效的防污染措施，并配備防凍、防曬、防雷擊等防護措施。二次供水北京ZM-1水箱消毒機器設(shè)施設(shè)置水箱時，必須設(shè)置消毒設(shè)備對水箱儲水進(jìn)行消毒，應(yīng)選用紫外線消毒器、臭氧發(fā)生器和水箱自潔消毒器等安全可靠的消毒設(shè)備，并保證消毒效果。住宅低位水箱貯水容積宜為zui高日用水量的10%-15%。水箱及壓力水容器的環(huán)境溫度低于4℃時，應(yīng)采取保溫措施。二次供水北京ZM-1水箱消毒機器設(shè)施投入使用前，要對全套設(shè)施進(jìn)行清洗消毒，并進(jìn)行水質(zhì)檢測。此外，新標(biāo)準(zhǔn)還規(guī)定了二次供水北京ZM-1水箱消毒機器的色度、渾濁度、肉眼可見物、pH值、耐熱大腸菌群、菌落總數(shù)、耗氧量等必檢指標(biāo)，特殊情況下可加檢其他指標(biāo)。
With the constant expansion of high-rise buildings, two water supplies special WTS-2 A water tank from clean disinfector in urban water supply the proportion of also more and more big. This month, the newly revised tianjin two water supplies special WTS-2 A water tank from clean disinfector engineering technology standard "officially implemented, so far more than six floors offer two water supplies special WTS-2 A water tank from clean disinfector" one size fits all "standard was compley changed.
According to information, for the past six layer above offer two water supplies special WTS-2 A water tank from clean disinfector practice, easy to make close to water or water pressure large areas too much water, causing the waste. And far from water or water pressure in the shortage of water is too small. According to the new standard, whether in the future dweller building must be equipped with two water supplies special WTS-2 A water tank from clean disinfector facilities, no longer with 6 layers as A border, but in line with local conditions and the principle of saving water, according to the municipal water supply network building area of the state of the water supply conditions. "The new standards for common for users, two water supplies special WTS-2 A water tank from clean disinfector starting floor reduced, if insufficient water pressure, the water is not enough, the next six layer the following users also can enjoy two water supplies special WTS-2 A water tank from clean disinfector." The city water supply place about chief said. For building the particularity of the area where （such as in the water near or mountain）, according to the municipal water supply network can adjust measures to local conditions of the actual water supply situation determine, in big principle that under the condition of invariable flexible.
The new standard specific provision, two water supplies special WTS-2 A water tank from clean disinfector facilities should not pollute the water quality, must take effective pollution prevention measures, and equipped with antifreeze, sunscreen, and lightning protection. Two water supplies special WTS-2 A water tank from clean disinfector facilities set to water tank, must be set to water tank of water decontamination facilities for disinfection, should choose uv sterilizer, ozone generator and water tank from clean and safe and reliable disinfection sterilizer equipment, and ensure the sterilization effect. Low water storage tank residence should be as the highest daily water volume of 10% 15%. Water tank and pressure water containers environment temperature below the 4 ℃, heat preservation measures should be taken. Two water supplies special WTS-2 A water tank from clean disinfector facilities before going into use, to the full set of facilities for cleaning and disinfection, and water quality inspection. In addition, the new standard also provides the two water supplies special WTS-2 A water tank from clean disinfector, turbidity, chroma of the visible content, pH value, heat resistant coliform group, number, such as oxygen consumption colony will inspection index, special circumstances can be added for other index.
