Abstract
The fluorine and arsenic removing water purifier consists of mainly attapulgite powder and active carbon, and is prepared through activating attapulgite powder, mixing activated attapulgite powder with active carbon in certain ratio, crushing to 80 mesh, crushing polyaluminium chloride powder to 80 mesh and other steps. The fluorine and arsenic removing water purifier has high fluorine and arsenic removing capacity, and can also eliminate inorganic heavy metal ions and polar and nonpolar organic molecules from water. The present invention may be used in purifying various kinds of surface polluted water, domestic sewage and industrial effluent, has low cost, easy use and great water treating capacity, and is suitable for rural district.
Description
Technical field
The present invention relates to a kind of water quality cleansing agent and preparation method thereof, more particularly, the present invention relates to a kind of defluorination, arsenic removal water quality cleansing agent and preparation method thereof.
Background technology
Endemic fluorine poisoning, arseniasis and endemic goiter all be since tap water in fluorine-containing, arsenic content is high, iodine deficiency causes in the water.These three endemic illness spread all over 29 provinces, cities and autonomous regions in the whole nation and municipality directly under the Central Government (except the Shanghai City), the lesion mainly is distributed in vast Rural areas, side area particularly backward in economy, the lesion population surpasses 100,000,000, has a strong impact on the healthy and Economic development of local people.
Defluorination, the arsenic removal technology that current various countries adopt mainly is activated alumina adsorption filtration, bone black adsorption filtration, aluminate coagulating precipitation, electrodialysis and reverse osmosis etc.Though these technology can defluorination, it is female to remove, can not remove up to standardly to high-content fluorine and arsenic in the water, and technical sophistication is used inconvenience.And China's defluorination, arsenic removal technology are in the experimental study stage.
Summary of the invention
The purpose of this invention is to provide a kind of defluorination, arsenic removal water quality cleansing agent, to solve the above-mentioned problems in the prior art.This water quality cleansing agent defluorination of the present invention, arsenic removal amount are big, can prevent and treat endemic fluorine poisoning, arseniasis.When removing high fluorine, high arsenic, can also can remove anhydrate Semi-polarity and nonpolar deleterious organic molecule simultaneously except that inorganic heavy metal ions such as the lead that exceeds standard in anhydrating, copper, chromium, iron, manganese, nickel, selenium, molybdenums.
Another object of the present invention provides a kind of preparation method of above-mentioned water quality cleansing agent.
Defluorination of the present invention, arsenic removal water quality cleansing agent, by weight, this scavenging agent is mainly composed of the following components:
Attapulgite ore powder 1-9 part gac 0.5-5 part
Be preferably: 2.5 parts of 2.5 parts of gacs of Attapulgite ore powder
The consumption of water quality cleansing agent each component of the present invention can also be
Attapulgite ore powder 1-9 part gac 0.5-5 part
Polymerize aluminum chloride 1-18 part
Be preferably 2.5 parts of 2.5 parts of gacs of Attapulgite ore powder
1.87 parts of polymerize aluminum chlorides
Water quality cleansing agent of the present invention is selected the Attapulgite ore powder, is because the Attapulgite ore powder is the magnesia nonmetalliferous ore that Gansu Province found and reconnoitred success first.Now proven reserve are 500,000 tons, and nearly more than 200,000,000 tons potential reserves is still arranged.This ore deposit grade is good, and steady quality is nontoxic, and easy strip mining transformation, especially association iodine ore deposit in the ore deposit, and ore is rich in tens kinds of trace elements such as needed by human body iodine, selenium, boron, zinc, calcium, and is rare both at home and abroad.It all has adsorption Attapulgite ore powder and gac, has defluorination, arsenic removal function, and can remove anhydrate Semi-polarity and nonpolar deleterious organic molecule simultaneously except that inorganic heavy metal ions such as the aluminium that exceeds standard in anhydrating, copper.In order to reach better effect, also selective polymerization aluminum chloride combination with it of water quality cleansing agent of the present invention, this is because polymerize aluminum chloride is a flocculation agent, and defluorination, arsenic removal function are also arranged.
The preparation method of scavenging agent of the present invention is earlier with the Attapulgite ore powder, carry out activation treatment with calcination activation method or acid heat activation method, then that Attapulgite stone flour after the activation treatment and gac is standby by described weight ratio powder mix to 80 order fineness, same powder to 80 order of polymerize aluminum chloride fineness is standby.
Activation treatment described in the above preparation method, wherein the calcination activation method was that the Attapulgite ore powder is placed stoving oven, 360 ℃ of roasting temperatures three hours.Wherein the acid heat activation method is with the Attapulgite ore powder, is activation treatment two hours in 4% the hydrochloric acid soln in concentration, and the solid-liquid ratio is 1.2: 1, then the Attapulgite stone flour after the activation treatment is dried two hours under 300 ℃ of temperature.
Water quality cleansing agent defluorination of the present invention, arsenic removal amount are big, when removing high fluorine, high arsenic, can remove inorganic heavy metal ions such as the lead that exceeds standard in anhydrating, copper, chromium, iron, manganese, nickel, selenium, molybdenum, also remove anhydrate Semi-polarity and nonpolar hazardous organic molecule simultaneously.But all kinds of faces of land of purifying treatment polluted water, sanitary sewage and various trade effluent.Water quality cleansing agent of the present invention is cheap, and the treating water 0.3-0.5 unit that only needs per ton is easy to use, and it is big to handle the water yield, is fit to vast Rural areas side area endemic fluorine poisoning particularly backward in economy, Endemic Arsenism Areas resident's use.Water quality cleansing agent can purify the band look the dirty water of peculiar smell, but purified tap water, natural drink water (rainwater is held back engineering, as Jiao Shui etc.), as clear as crystal behind the purification of water quality, soft mouth feel is fragrant and sweet, and water quality can reach national hygiene standard for drinking water.
