Bobby, it is extremely lucky to have clean water necessary for life. The United Nations Global Environment Outlook: Protecting the Environment for Development (GEO-4) reports that climate change, aquatic ecosystems
The abuse and degradation of fish and the over-exploitation of fish resources are changing the water environment, affecting human well-being and the realization of the United Nations Millennium Development Goals.
The water quality in most areas is declining. There is evidence that the diversity of freshwater species and ecosystems is rapidly declining, and its degradation rate is often faster than that of terrestrial and marine ecosystems. 1987-
In 2003, the number of freshwater vertebrates decreased by about 50% on average, much faster than that of terrestrial and marine life. 1/5 Freshwater fish are either endangered or extinct. by the river
The "deterioration and poisoning" of the ecosystem has threatened the health and livelihood of people who rely on rivers for irrigation, drinking and industrial water.
The increasingly serious water pollution has threatened the survival and safety of human beings and become the main obstacle to the sustainable development of human health, economy and society. Globally, water pollution is still the cause of diseases.
And death. According to the statistics of the World Health Organization, many countries in the world are facing water pollution crisis. In developing China countries, 3-4 million people die from diseases related to water pollution every year.
Most of them are children under 5 years old. Statistics show that 654.38+02 billion people in the world get sick every year because of drinking unclean water. Among them, they die every year from diseases caused by water pollution such as cholera, dysentery and malaria.
Millions of people.
Our country's survey shows that there are more than 300 million people with unsafe drinking water in rural areas, including about 63 million people who drink high fluorine water, 2 million people who drink high arsenic water, 38 million people who drink brackish water, and 65.438+0.9 billion people.
The content of harmful substances in drinking water exceeds the standard.

Second, when washing hands, it is more water-saving to wash with a basin than with running water, and the same is true when washing vegetables and fruits or washing dishes. It takes a lot of water to wash without stopping running the tap, and intermittent washing can save water. Save water and reuse it.
The washing machine at home consumes a lot of water. In order to save water, manufacturers and researchers have made great efforts to save water as much as possible on the premise of ensuring the cleanliness of clothes.
This inclined shape is not for beauty or originality, and the inclined plane design of 10 degree has its own reasons. After the washing drum is tilted 10 degree, its water level is relatively deep, which can achieve a large number of washing effects. So save water.
The program set by the washing machine is generally one wash and two rinses, and water is mainly spent on rinsing. If washing powder is not used, won't rinse water be saved?
This ultrasonic washing machine can send out 20,000 shock waves per second, which can "shake" the dirt on clothes. A special water electrolysis device is also installed in the washing machine, which can decompose water molecules in tap water into hydrogen ions and oxygen ions, and use the ions to decompose and adsorb stains and dust to clean clothes. Two-pronged, this washing machine without washing powder saves more than 30% water than ordinary washing machines.
Also, the water level of the washing machine should not be set too high, otherwise there will be no friction between clothes, and it will waste water if it is not cleaned.
In addition to washing machines, toilets are also a major household water user, accounting for about 35% of residents' water consumption. A family of three will wash away more than 3,000 liters of water a month.
Technicians have developed a new type of toilet, which only uses 4 liters of water each time, saving one-third to one-half of the water compared with the existing toilet.
Its water tank accumulates air while filling water, compresses the accumulated air by using the pressure in the water supply pipeline, and then pushes the water to flow into the bedpan at a higher speed. Different from the "pull" force of traditional sanitary ware, this new sanitary ware uses "push" force to discharge dirt, which has great impulse, so it can save water.
In fact, other domestic water can also be used to flush toilets. For example, after the last rinse, the clothes are washed clean, and the water discharged from the washing machine looks cleaner. Unfortunately, it flows directly into the sewer. There is also water such as washing your face and vegetables. It would be nice if it could be reused. Wu Hanping, an amateur inventor, developed a set of domestic water reuse device and obtained a national patent. He connected the sink in the kitchen, the basin in the bathroom and the water tank in the bathroom to a water storage tank. Clean water from the sink and basin enters the storage tank for flushing the toilet.
Now I'll teach you the secret of water saving 1. To use the water-saving toilet, please install a two-stage flushing accessory for the ordinary toilet. 2. Remove the floating cake under the water tank to form a stepless control water outlet.
3. The flushing time of the urinal automatic flusher is shortened. 4. Water the flowers, wash the car and scrub the floor with clean water such as rice washing water, laundry water, dish washing water and bath water. 5. The carpet cleaning method is changed from wet or steam to dry powder. 6. Recycle the water collected by dehumidifier and the wastewater from water purification equipment such as pure water machine and distilled water machine.
