Abstract

A process for preparing superpure drinking water includes such steps as cleaning, biochemical treating, oxidizing, membrane-filtering and holding quality up to users' taps. Its apparatus is composed of a flash mixer, a separator, an ozone reactor, a biochemical reaction pool, a filter pool and a membrane filter. Its advantages are high effect, high quality of water, direct drinking, and low cost.

Description

technical field [0001] The invention relates to a water treatment process, in particular to a device and method for producing ultra-clean direct drinking water. Background technique [0002] The shortage and pollution of fresh water resources has become a worldwide problem, and ultra-clean direct drinking water is the product of this environment. The history of human drinking water has been a long experience from the introduction of natural water to the artificial production of tap water. It has been 200 years since the establishment of the first waterworks in the world in 1804. Today, human beings have questioned tap water for drinking, and it is another leap for human beings to drink healthy water under the condition that the water only enters the stomach of the human body and the environment of the human body for pure eating and drinking. There are thousands of organic pollutants in drinking water sources. According to the U.S. Environmental Protection Agency in the mid-...
