Deionized water equipment meets the water supply demand

In order to ensure human health, the quality of centralized water supply should meet some basic requirements. First of all, drinking water must not contain pathogenic microorganisms, in order to prevent the occurrence and prevalence of aquatic infectious diseases; Secondly, the chemical substances and radioactive substances contained in the water shall not endanger human health, (deionized water equipment) should ensure that people in the lifetime drinking conditions do not cause acute and chronic poisoning and potential long-term harm (teratogenic, carcinogenic, mutagenic effect). In addition, we should ensure that the sensory properties of drinking water good, for people to drink.

Due to the large scope OF centralized drinking water supply, once the water source and the process of water supply are contaminated by various chemical substances and pathogenic microorganisms, and without effective purification and disinfection treatment, it can cause a large range of acute and chronic poisoning and infectious diseases. Therefore, the sanitation supervision and management of centralized water supply should be strengthened to ensure the safety of water supply.

(2) Decentralized water supply. Distributed water supply means that residents directly get water from water sources for drinking and living. Water extraction methods mainly include water extraction from mechanical Wells, hand-pressed pump Wells and manual water extraction. The use of electric water lifting in mechanical Wells not only saves labor, but also can prevent the pollution of the water well and is beneficial to the protection of source water. Therefore, this method should be advocated vigorously in the rural water upgrading work of our country. Compared with the large well, the hand pump well has the advantages of less exposure, light pollution and easy construction. In the process of distributed water supply, it is generally not purified and disinfected, so the water quality is poor.
