环境专家指出:“19世纪争煤炭,20世纪争石油,21世纪争淡水”。而对日益减少的水资源,近年来,全社会都在倡导节约用水,并采取先进技术,提高水的重复利用率等,但社会上还有许多人在以不同的方式浪费和污染着水资源。暂且不计水在各种制造、加工、冷却、洗涤等过程中被浪费和污染的数量,仅水龙头漏水的现象就十分普遍。据测算。“一滴水”1小时可以集到3.6公斤水,1个月可集到2.6立方米,这些水量可以满足一个人一年的生活所需。 Environmental experts pointed out: “19th century coal, 20th century fighting oil, 21st century fighting fresh water ”. In recent years, the society has been advocating water conservation and adopting advanced technologies to improve the water recycling rate. However, there are still many people in the society who waste and pollute water resources in different ways . For the time being, only the amount of water wasted and contaminated during various manufacturing, processing, cooling and washing processes is only common in faucets. It is estimated. “A drop of water ” 1 hour can gather to 3.6 kilograms of water, 1 month can gather to 2.6 cubic meters, the amount of water to meet the needs of one year of life.
