随着全球人口的急剧增长,工业的发展迅速。人类对淡水资源的需求以惊人的速度扩大,与此同时,社会中日益严重的各种污染悄悄地吞噬着大量可供消费的水资源。水资源短缺的问题显得日益突出。在这种情况下,中水回用因具有节水和治污双重功用,受到了特别的关注。而中水回用的经济性是决定中水回用能否广泛应用的关键因素。 With the rapid growth of the global population, the industry has developed rapidly. The human demand for freshwater resources is expanding at an alarming rate. At the same time, the increasingly serious pollution in society has swallowed a large amount of water resources that can be consumed. The problem of shortage of water resources has become increasingly prominent. Under this circumstance, the reclaimed water has received special attention due to its dual functions of water saving and pollution control. The economics of reusing water is the key factor in determining whether the reuse of water can be widely used.
