我国人均水资源占有量为2300m2,仅为世界人均占有量的1／4,是全球13个水资源贫乏的国家之一。据统计,全国668座大中城市中有400多座缺水,而水污染等人为因素的影响进一步加剧了水资源短缺的状况,每年大量的工业废水和城市污水未经处理排入河流、渠道,使64％的城市河段的水受到中度或重度污染。水资源的紧缺,水环境的恶化,向水处理及相关行业提出了挑战。
China’s per capita share of water resources is 2300m2, accounting for only 1/4 of the world average, making it one of 13 water-scarce countries in the world. According to statistics, there are more than 400 water shortages in 668 large and medium-sized cities across the country, and human factors such as water pollution further aggravate the situation of water shortage. Every year, a large amount of industrial wastewater and urban sewage are discharged into rivers and channels 64% of the urban river water was moderately or heavily polluted. The scarcity of water resources and the deteriorating water environment pose challenges to water treatment and related industries.
