Ceramic membrane drinking water purification device

Abstract

A ceramic membrane drinking water purification device comprises a ceramic membrane shell, a raw water tank, a cleaning water tank and a water production tank; a ceramic membrane is arranged in the ceramic membrane shell, a water inlet is formed in the lower end of the ceramic membrane shell, a reverse cleaning opening is formed in the upper end of the ceramic membrane shell, and a water productionopening is formed in the ceramic membrane shell between the water inlet and the reverse cleaning opening. Due to the fact that the chemical property of the ceramic material is extremely good, chemical cleaning in an approximate full PH value range can be adopted, and the ceramic material is also suitable for chemical cleaning with high-concentration oxidizing agents and even organic solvents; even under the condition of extreme pollution, various high-concentration chemical agents can be used for cleaning, yet the organic membrane still has certain limitation on the selection of the agents; in addition, the hydrophilic performance of the ceramic is far higher than that of PVDF, the cleaning restorability is far better than that of PVDF, and the cleaning restorability is far better than that of an organic membrane due to the fact that the hydrophilic performance of the ceramic is far higher than that of the organic membrane.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a ceramic membrane drinking water purification device. Background technique [0002] The problem of water pollution has become a common political, social, economic and important scientific and technological problem faced by many countries and regions. For developing countries, the situation is even more severe. According to statistics, 82% of the inland rivers and lakes in my country have been polluted to varying degrees. The traditional tap water production is to process the source water such as river water, lake water, well water and spring water through coagulation, sedimentation, filtration, disinfection and purification. Remove algae, humus, sediment, bacteria and viruses from the source water and produce drinking water. [0003] However, with the increasing pollution of source water, the traditional process can no longer meet the purification requirements, cannot ef...
