2007年7月1日,《生活饮用水卫生标准》(GB5749-2006)正式施行。新标准规定的指标由原来的35项大幅增加到106项,部分指标的限值也更加严格了。因此,在新标准的贯彻和执行当中势必会遇到一些问题和困难。其中一个问题就是如何尽快改造供水设施,提高净水技术、工艺和管理水平。无疑,新标准的实施提高了供水水质,加快了水厂改造的步伐。但是,完全按照标准实施在目前的情况下是不可能的,为了一方面提升供水水质,一方面给各个水厂提供缓冲的机会,于是从新标准中提出了40多项必须满足的参数,并且给出了一个五年的宽限期,即将饮用水全部达标的最后期限推迟到2012年7月1日。然而,五年的时间并不长,供水企业面临的挑战显而易见。中小城市的水厂改造工作已经开始。于是,我们从网上的专业论坛中搜集了给水处理厂技术改造的一些实际问题,供大家参考。
July 1, 2007, “drinking water health standards” (GB5749-2006) came into effect. The new standard provides a substantial increase from the original 35 to 106 items, some of the indicators are more stringent limits. Therefore, some problems and difficulties are bound to be encountered in the implementation and implementation of the new standards. One of the problems is how to transform water supply facilities as soon as possible so as to raise the level of clean water technology, technology and management. Undoubtedly, the implementation of the new standard has improved the quality of water supply and accelerated the pace of waterworks renovation. However, it is impossible under the current circumstances to fully implement the standards. In order to improve the water quality on the one hand and on the other hand to provide buffering opportunities to individual water plants, more than 40 parameters that must be met are proposed in the new standard, After a five-year grace period, the deadline for the full compliance of drinking water was postponed until July 1, 2012. However, the five-year period is not long and the challenges facing the water supply enterprises are obvious. Waterworks renovation work in small and medium-sized cities has begun. As a result, we have collected some practical problems of technological transformation of water treatment plants from the online professional forum for your reference.
