Drinking water treatment technology adopting carbon fibers

Abstract

The invention relates to the technical field of drinking water purification and particularly relates to a drinking water treatment technology adopting carbon fibers. According to the drinking water treatment technology, the problems of turbid water quality, abnormal water odor and off-odor can be effectively solved, and inorganic substances such as iron, manganese and the like in water are effectively purified; in addition, organic compounds and bacteria such as cyanogen, chlorine, fluorine, phenol and the like in a water body can be removed and the existing drinking water safety problems canbe effectively solved. The drinking water treatment technology comprises the following steps: firstly, adsorption treatment: effectively adsorbing and removing macromolecular substances in water by utilizing relatively large empty area and specific surface area of the carbon fibers; secondly, filtration treatment: carrying out further treatment on pollutants in the water body through the adsorption of ores in a filtration module; thirdly, bacteriostatic treatment: killing microorganisms in the water body and inhibiting regeneration of the microorganisms; fourthly, activation treatment: carrying out activation treatment on the water quality through the action of a gradient magnetic field.

Problems solved by technology

[0002] With the increasingly serious environmental pollution, drinking water often has problems such as turbid water quality, water body odor, and peculiar smell, and drinking water often contains inorganic substances such as iron and manganese, and organic compounds such as cyanide, chlorine, fluorine, and phenol in drinking water The content of bacteria and bacteria is also gradually increasing, and the safety of drinking water has been paid much attention. At present, the purification of drinking water is mainly through the adsorption of macromolecular substances in water, reducing the concentration and toxicity of water, etc. These substances will not only affect drinking water. The purity of the water will also endanger human health. The traditional water treatment process uses coarse-grained activated carbon to treat drinking water. This treatment method is not effective in purifying drinking water and is not effective in removing some organic matter Ideal, with some limitations:

[0003] (1) For trihalomethanes, the adsorption capacity of activated carbon is low;

[0004] (2) The removal effect of activated carbon on the precursors of disinfection by-products is also limited

Experimental studies have shown that the molecular weight of organic matter removed by activated carbon in drinking water treatment is mainly distributed between 500 and 1000u (Dalton), organic matter with too large molecular weight cannot enter the microporous adsorption area of ​​activated carbon, and the molecular weight of drinking water source water Small substances contain more carboxyl groups, hydroxyl groups, etc., and the polarity of the molecules is stronger. Because activated carbon is a non-polar adsorbent, the adsorption effect on polar molecules is poor.
