Attapulgite water quality purifying agent and preparation method thereof

Abstract

The invention discloses an attapulgite water quality purifying agent and a preparation method thereof, and belongs to the technical field of water treatment. The purifying agent is prepared from the following components: modified attapulgite clay, activated carbon, diatomite, poly-aluminum ferric silicate, saw dust, liquorice root, cortex moutan and lemon peel. The preparation method comprises the following steps: performing purification, acidification and thermal modification on natural attapulgite clay, putting the modified attapulgite clay, the activated carbon, the diatomite and the saw dust into a reaction container, adding extracting liquid of the liquorice root, the cortex moutan and the lemon peel, mixing and stirring uniformly, performing ultrasonic treatment and standing to obtain a mixture; removing water from the mixture, adding the poly-aluminum ferric silicate, stirring completely and uniformly, and drying; and putting into a muffle furnace, roasting, cooling and crushing to obtain the water quality purifying agent. The attapulgite water quality purifying agent has the effect of efficiently removing dirt and impurities and can effectively remove bacteria from the water and prevent bacterial breeding; furthermore, the preparation method is simple and practical, is mild in condition and suitable for industrial production.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to an attapulgite water quality purifier and a preparation method. Background technique [0002] In recent years, with the development of the economy and the progress of industry and agriculture, it has brought about the destruction of the living environment of human beings and the destruction of nature. The by-products accompanying the production and use of various products have caused serious environmental pollution. The pollution of fresh water resources that human beings depend on is also increasing day by day. Among water pollution, arsenic pollution has attracted widespread attention. The main forms of arsenic in water are arsenite ion and arsenate ion. At the surface of water bodies, arsenic in the form of arsenite is often oxidized to arsenate. Arsenite and arsenate ions enter the soil, that is, react with iron, aluminum, calcium, magnesium and other ions in the ...

In addition, the fluoride pollution in drinking water has also attracted more and more attention. When the concentration of fluoride ions reaches a certain amount, it will cause great harm to the human body, and it will also damage the soil quality in the environment, and may also cause human and natural organisms poisoned

In addition, some organic substances in the water, such as humic acid, pollutants from domestic sewage and industrial wastewater, not only lead to water pollution and deterioration of water quality, but also cause bacteria to grow, seriously endangering people's health

[0003] At present, the sewage purifiers with multiple functions of adsorption and sterilization on the market have poor stability of treatment effect, complicated treatment process, large one-time industrial investment and many residues. The removal rate of bacteria, algae, harmful heavy metals, etc. is not high; although the effect of aluminum sulfate treatment is better, but the cost is high, the effect will gradually deteriorate over time, the purification efficiency is low, the cost is high, and the purified water will be Residues of substances harmful to the human body seriously affect the quality of drinking water
