地球的都是由水所覆盖,但人类可以饮用的水却所占不多,仅有河流,地下水和冰川水等,而人类的活动对这些水资源所造成的破坏而随着科技的发展而更加的严重,且随着经济发展和人们生活水平的提高,对饮用水的要求也越来越高.这一切都对净化工艺的发展提出了新的要求.常规水处理工艺对此类水源水的处理效果很差,难以达到国家的饮用水标准,通过对多种水处理技术包括强化常规处理技术,高级氧化、吸附和膜处理技术等在微污染水源水处理中的原理、作用及优缺点等进行了探讨
The earth is covered by water, but humans can be used for drinking water actually occupied much, only rivers, groundwater and glacial water etc, and human activities on the water resources the damage and with the development of science and technology and more severe, and with the development of economy and the improvement of people's living standard, the requirements for drinking water more and more is also high. All this to the development of purification process puts forward new requirements. Conventional water treatment technology of such source water treatment is very poor, it is difficult to achieve national standards for drinking water, through to the variety of water treatment technologies including strengthening routine treatment technology, chemical, and biological pretreatment, advanced oxidation, adsorption and membrane processing technology in the slightly polluted water treatment principle, function and advantages and disadvantages are discussed
