Problems solved by technology

Because the existing tap water contains chlorine, bleaching powder, bacteria, etc., it is not suitable for direct drinking by the human body, and boiling tap water can only kill some bacteria. Heavy metals, dust, residual chlorine and chemical pollutants in the water cannot be removed. To ensure human health, tap water needs to be purified before use

Abstract

The invention discloses a tap water purification technique which comprises a pretreatment unit, a middle section treatment unit and a terminal treatment unit, wherein the pretreatment unit comprises a raw water pump, a multimedia filter, an active carbon filter, a sodium cation exchanger and a secondary filter; the middle section treatment unit comprises a reverse osmosis combination unit; and the terminal treatment unit comprises an ozone sterilizer. By using the technique, the purified tap water can be directly drunk without adding any bactericide, thereby ensuring the human health.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a tap water purification process. Background technique [0002] Water is an important part of the human body. The water in the human body accounts for about 50% of an adult's body weight. The average daily water consumption of a normal person is 2000-2500 ml, and the oxidation of substances in the body can produce 300 ml of water, so it should be replenished every day About 2000 ml of water, most of which are obtained through drinking water. Because the existing tap water contains chlorine, bleaching powder, bacteria, etc., it is not suitable for direct drinking by the human body, and boiling tap water can only kill some bacteria. Heavy metals, dust, residual chlorine and chemical pollutants in the water cannot be removed. To ensure human health, tap water needs to be purified before use. Contents of the invention [0003] The technical problem mainly solved by the pr...
