It is known to all that water is the source of life. If there is no water, no matter human beings, animals, plants, etc. can not survive, which will be a serious ecological cycle problem! So water safety is something we have to be concerned about.

If someone drinks the polluted water, it will bring disease to the body! Therefore, drinking water safety and human health are inseparable! This will involve the problem of water quality testing, this chapter we want to understand is… The main monitoring project on drinking water!

For testing standards, China’s issued “drinking water sanitation standards” (GB5749-2006) there are 106 items that need to be tested, but each industry site testing projects will be different, not to say that every place needs to test the 106 projects. What are the specific projects? Please look down!

The drinking water online monitoring project can be viewed from the following 4 aspects!

1.Sensory properties: chroma, turbidity, smell, taste, visible to the naked eye, etc.

2.General chemical indicators: pH, hardness, heavy metals (such as: iron, manganese, copper, zinc, aluminum, etc.), volatile phenols, anionic synthetic detergent, sulfate, total dissolved solids, oxygen consumption, etc.;

3.Physical indicators: nitrate nitrogen, selenium, cadmium, hexavalent chromium, lead, silver, formaldehyde, etc.;

4.Bacteriological indicators: total number of bacteria, total coliform group, fecal coliform group, etc.
