Reclaimed water should not be used for bathing.
1. Reclaimed water generally refers to reclaimed water, and reclaimed water refers to the water that can be used beneficially after wastewater or rainwater is properly treated to meet certain water quality indicators, meet certain use requirements, and can be used beneficially. Compared with seawater desalination and cross-basin water transfer, reclaimed water has obvious advantages. From an economic point of view, the cost of reclaimed water is the lowest, and from the perspective of environmental protection, sewage recycling helps to improve the ecological environment and achieve a virtuous cycle of water ecology.
2. Reclaimed water is a very valuable water resource with large quantity, stable water quality, and little influence by season and climate. There are many ways to use reclaimed water, which can be divided into direct use and indirect use according to the relationship with users, and direct use can be divided into local use and centralized use. In most countries, reclaimed water is mainly used for irrigation of farmland, mainly indirectly; In a few countries, such as Japan, reclaimed water is mainly used for urban non-potable water, mainly for local use; The new trend is environmental water use for the "water landscape" of the urban environment.

Reclaimed water, also known as "reclaimed water", is treated sewage for reuse. Because the water supply is called "upper water" and the sewage discharge is called "lower water" in urban construction, the meaning of reclaimed water is taken from the two.
There are urban sewage treatment plants that treat and reuse reclaimed water, and there is also a community or even a single house that reuses it on its own. In the community or housing area, only relatively clean sewage, such as bathing water, swimming pool water, kitchen drainage, etc., is generally collected for simple treatment, such as filtration, sedimentation, etc. The reclaimed water for centralized reuse in the city needs to be set up separately, so the investment is large, but it can save water resources and reduce the amount of sewage discharge, so it can greatly reduce the cost of water supply and sewage treatment.
Reclaimed water reuse is mainly used for flushing toilets, irrigation of green spaces, washing streets, car washing, etc.
At present, due to the scarcity of freshwater resources in the world, reclaimed water is getting more and more attention. Japan has been developing reclaimed water utilization since the 60s of the 20th century; The United States also began to develop it in the 80s; The People's Republic of China began to study the use of reclaimed water in 1980, formulated the Code for Water Utilization in Architectural Design in 1983, began to build a reclaimed water pipeline network in Beijing on a trial basis in 1990, promoted it in several cities such as Dalian, Qingdao and Tianjin in 1993, and popularized it to the whole country in 1998. But there are still some doubts about people's perceptions.
With the increase of water consumption for human production and living, and the further depletion and pollution of freshwater resources, the utilization of reclaimed water has become the focus of attention all over the world.

Hello dear, I am the answer to the question Konjac teacher, I am happy to ask you a question. Reclaimed water cannot be bathed. Reclaimed water refers to the water that can be used for beneficial purposes after wastewater or rainwater is properly treated, reaches certain water quality indicators, meets certain use requirements, and can be used beneficially.
Neutralized water is mainly used to adjust the pH value to achieve neutrality or a specific pH. It has a wide range of applications in many fields, including the following:1
Industrial applications: In industrial production, neutralized water is often used to control and stabilize the pH of the treated liquids to ensure proper process operation. For example, in the chemical and pharmaceutical, metal processing, textile, electronics and other industries, it is often necessary to use neutralized water for acid-alkali grinding rock neutralization reaction.
2.Environmental protection: Neutralized water can also be used to treat wastewater and discharges to meet environmental discharge standards.
By neutralizing the acids and alkalis in the wastewater, the pollution to the environment can be reduced and the effect of wastewater treatment can be increased. 3.Drinking water treatment:
In the process of drinking water treatment, neutralized water can be used to adjust the pH of the water body to meet the safety standards for human drinking. By neutralizing the treatment of water, the acidity or alkalinity of the water can be reduced, and the taste and water quality can be improved. 4.
Laboratory application: In the laboratory, neutralizing water is often used to dilute and adjust the pH of the solution to meet the needs of different experiments. It can be used in various scientific research fields such as the preparation of chemical reagents, biological experiments, analytical tests, etc.
It is not recommended to bathe with water, hamsters are hairy, it is difficult to dry them thoroughly, it is easy to catch a cold when bathing with water, and hamsters are animals that live in the desert and do not like moisture.
