随着高层建筑规模的不断扩大,二次供水北京ZM-1水箱消毒机器在城市供水中所占的比例也越来越大。本月起,新修订的《天津市二次供水北京ZM-1水箱消毒机器工程技术标准》正式实施,至此6层以上提供二次供水北京ZM-1水箱消毒机器的“一刀切”标准被改变。
据了解,过去只为6层以上提供二次供水北京ZM-1水箱消毒机器的做法,容易使靠近水厂或水压大的地区水量过大,从而造成浪费。而距水厂较远或水压不足的地区水量过小。根据新标准,今后居民楼是否必须配备二次供水北京ZM-1水箱消毒机器设施,不再以6层为界,而是本着因地制宜与节约用水的原则,根据建筑物所在区域市政供水管网的供水状况等情况确定。“新标准对于普遍用户而言,二次供水北京ZM-1水箱消毒机器的起始楼层降低了,如果水压不足、水量不够,今后6层以下的用户也能享受二次供水北京ZM-1水箱消毒机器。”市供水处有关负责人表示。对于建筑物所处区域的特殊性(如处在水厂附近或山区),可因地制宜根据市政供水管网的实际供水状况确定,在保证大原则不变的情况下灵活掌握。
新标准明确规定,二次供水北京ZM-1水箱消毒机器设施不应对水质产生污染,必须采取有效的防污染措施,并配备防冻、防晒、防雷击等防护措施。二次供水北京ZM-1水箱消毒机器设施设置水箱时,必须设置消毒设备对水箱储水进行消毒,应选用紫外线消毒器、臭氧发生器和水箱自洁消毒器等安全可靠的消毒设备,并保证消毒效果。住宅低位水箱贮水容积宜为zui高日用水量的10%-15%。水箱及压力水容器的环境温度低于4℃时,应采取保温措施。二次供水北京ZM-1水箱消毒机器设施投入使用前,要对全套设施进行清洗消毒,并进行水质检测。此外,新标准还规定了二次供水北京ZM-1水箱消毒机器的色度、浑浊度、肉眼可见物、pH值、耐热大肠菌群、菌落总数、耗氧量等必检指标,特殊情况下可加检其他指标。
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.
