Will the waterworks recruit people from outside?

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.

1. What is the standard index of tap water?

The standard index of tap water is GB5749-2006. When testing tap water, the testing items are divided into toxicological indicators, radioactive indicators, chemical indicators, microbial indicators and sensory traits. Tap water refers to the standard water produced by tap water treatment plant after purification and professional disinfection, which can be used for people's life and use.

Second, what is the tap water suppression standard?

When tap water is pressed, its standard is greater than 0.2 1PA. Moreover, the speed of water flowing out of the faucet corresponds to the pressure between tap water. The greater the pressure of tap water, the greater the flow of tap water. Moreover, the flow of tap water is also related to the bending of water pipes. If the water pipe is damaged, the flow of tap water will gradually decrease, and then the water pressure will also decrease.

Third, what are the precautions for buying water pipes?

1, when buying a water pipe, measure the length of the water pipe, and then buy a water pipe with the corresponding length. At this time, you should go to the market to buy, and you must choose qualified water pipes. In this way, the quality can be guaranteed when it is used.

2. Moreover, the length of water pipes should not be purchased too long, so as to avoid unnecessary situations and waste after installation. However, you can't buy too little. If you buy too little, there will be fewer water pipes after installation, and then you have to buy them again, which is more troublesome

3, and when choosing water pipes, you can choose brand water pipes. In this way, when we use it, its effect will be better, and we can use it with confidence.

Four, the water purification process of waterworks mainly includes flocculation, sedimentation, filtration, chlorination, etc. , as follows:

1, adding flocculant to react with impurities in water for adsorption;

2, precipitating macromolecular impurities after the reaction;

3. Further filtering with filters filled with quartz sand, activated carbon and other filtering materials;

4, chlorine disinfection before delivery.

Because the disinfection method of tap water is not perfect enough, most tap water drinkers will use tap water. In the disinfection process, tap water is disinfected with bleaching powder (agent). Even if efforts are made to filter, there is still a small amount or trace of chlorine (bleaching powder). When water is heated at 100℃, chloroform will be produced, which is a carcinogen.

Chlorine is dissolved in water and reacts with water to produce hypochlorous acid and hydrochloric acid, and hypochlorous acid plays a major role in the whole disinfection process. For inorganic substances with peculiar smell, they can be thoroughly oxidized and disinfected. For algae, bacteria and other living natural substances, they can penetrate the cell wall, oxidize their enzyme systems (enzymes are biocatalysts), inactivate them, hinder the life activities of bacteria and die.

People's Republic of China (PRC) (China) Labor Contract Law

Article 10 To establish labor relations, a written labor contract shall be concluded.

If a labor relationship has been established and a written labor contract has not been concluded at the same time, a written labor contract shall be concluded within one month from the date of employment. If the employer and the employee conclude a labor contract before employment, the labor relationship shall be established from the date of employment.
