Abstract

The invention relates to the technical field of water purification, and aims to provide a rural drinking water purification system with an arsenic removal function. The system can effectively remove arsenic from drinking water, also can remove other heavy metal pollutants such as chromium and the like, and has a good water purification effect. The system comprises a raw water pool, a sand filtration tank, an activated carbon tank, an iron oxyhydroxide tank and a purified water storage tank which are connected in turn, wherein a water feeding pump is arranged on a connecting pipeline of the raw water pool and the sand filtration tank; an ultrafilter is arranged between the sand filtration tank and the activated carbon tank; an ultrafiltration membrane is arranged in the ultrafilter; a water inlet of the ultrafilter is connected with a water outlet of the sand filtration tank through a pipeline; and a water outlet of the ultrafilter is connected with a water inlet of the activated carbon tank through a pipeline.

Description

technical field [0001] The invention relates to the technical field of water purification, in particular to a rural drinking water purification system with the function of removing arsenic. Background technique [0002] Arsenic and its compounds are recognized human carcinogens. Due to human activities such as water intake for irrigation, mining, especially digging wells for drinking water, as well as the influence of the ecological environment and climate in various regions, arsenic compounds in the earth's surface are dissolved into surface water in the form of arsenate and arsenite in large quantities, adding to the The pollution of natural water bodies by industrial wastewater such as metallurgy, chemical industry, chemical pharmaceuticals, tanning, textiles, wood processing, glass, paint pigments and ceramics has brought serious water arsenic pollution problems. Arsenic pollution has brought a particularly serious drinking water crisis to rural areas. [0003] The com...
