Will the waterworks recruit people?

The waterworks will recruit people from outside. These units recruit individuals every year, but it is difficult for ordinary people to get in, it is very easy to go to work, and the salary is high. Water supply company is one of the state-owned enterprises with better wages and benefits.

Water conservancy project plan

From the above formula, according to the conservation of chlorine atoms, it can be known that a certain amount of chlorine reacts with water to finally generate hydrogen chloride twice as much as the original chlorine, and the generated hydrogen chloride is also very small, because the amount of chlorine used in the process of generating water is very small. According to physiology and health knowledge, we know that human gastric juice contains a small amount of hydrochloric acid.

Therefore, it can be considered that a small amount of hydrogen chloride has no effect on human health and can be almost ignored. In addition, hydrogen chloride is a volatile gas. According to this property, it can be inferred that there is almost no hydrogen chloride in boiling water.

In the disinfection process, the amount of chlorine is very small. Generally, only about 0.005g of chlorine is introduced into 1L water. It can be said that as long as the factory tap water meets the normal national standards, the chlorine put into the tap water will completely react with water to generate other substances, so it can be considered that the factory tap water does not contain Cl2. The so-called "maintaining a certain amount of residual chlorine at the end of urban tap water pipes" actually refers to chlorine, not chlorine.
