Abstract
The invention belongs to the technical field of drinking water purification and specifically relates to a drinking water purifier and a preparation method thereof. The drinking water purifier is formed by mixing the following components in parts by weight: 1 part of acrylamide graft copolymer, 1 part of activated carbon and 0.5 part of sodium silicate. The preparation method of the drinking water purifier comprises the following steps of: (1) adding chitosan into a reaction kettle, dripping a mixed solution of acrylamide and acrylic acid, and reacting for 50 minutes to obtain the acrylamide graft copolymer; and (2) performing superposition mixing on the obtained acrylamide graft copolymer, the activated carbon and the sodium silicate according to the weight ratio of 1: 1: 0.5 to obtain the drinking water purifier. The drinking water purifier adopts the method of grafting the copolymer acrylamide on a natural high polymer and is compounded with other adsorbing agents which are harmless to people and animals to purify water, so that the water purification purpose is achieved.
Description
Technical field
The invention belongs to the technical field of drink water purifying, be specifically related to a kind of clean reagent in drinking water and preparation method thereof.
Background technology
Although the drink water purifying technology is existing a lot, majority is not suitable with Rural water supply dispersion, low cost, and the current conditions that service discharge is little also lacks convenient, the economical and practical scavenging agent that is applicable to the rural rivers tap water at present.
Development along with science and technology, recently find that aluminium element has certain harm to human body, and traditional water purification agent generally all contains the aluminium salt compounds, after water is carried out complexing, still understand residual a small amount of aluminium element in water although removed most of harmful material, human body is existed potential harm.
Summary of the invention
The object of the invention is to for the defective of above-mentioned existence and a kind of clean reagent in drinking water and preparation method thereof is provided, this clean reagent in drinking water adopts the method for natural polymer graft copolymerization acrylamide, compound other sorbent materials to the person poultry harmless purify water, have reached the purpose of water purification.
Technical scheme of the present invention is: clean reagent in drinking water is formed by the component proportion of following weight part: 1 part of acrylamide grafted copolymer, 1 part of gac, 0.5 part of water glass.
The raw materials of described acrylamide grafted copolymer comprises following component by weight: 1 part of chitosan, 1 part of acrylamide, 0.5 part in vinylformic acid.
The preparation method of described clean reagent in drinking water may further comprise the steps:
(1) be that 1 part chitosan joins in the reactor with weight part, be heated to 40 ℃, under the condition that stirs, carry out water dissolution, after being warming up to 65 ℃ after the dissolving, logical nitrogen 10 minutes is with the Bas Discharged in the solution, then add the Potassium Persulphate that accounts for acrylamide weight 0.01～0.1%, after stirring, drip acrylamide and acrylic acid mixing solutions, wherein the acrylamide weight part is 1 part, and the vinylformic acid weight part is 0.5 part, drips acrylamide and acrylic acid mixing solutions in 10～30 minutes, keep 50～80 ℃ of temperature. reacted 50 minutes, and obtained acrylamide grafted copolymer;
(2) with the acrylamide grafted copolymer of step (1) gained and gac, water glass by weight 1:1:0.5 superpose and mix, be followed successively by from top to bottom gac, water glass, acrylamide grafted copolymer, namely obtain clean reagent in drinking water.
Beneficial effect of the present invention is: clean reagent in drinking water of the present invention is by acrylamide grafted copolymer, and the mixing that superposes of gac, potassium silicate is followed successively by gac, potassium silicate, acrylamide grafted copolymer from top to bottom.Gac, potassium silicate carry out adsorption treatment to tap water first, remove larger granule foreign, finally by crossing acrylamide grafted copolymer, with minute impurities flocculation sediment in the tap water, purify layer by layer, purify thoroughly.The raw materials of acrylamide grafted copolymer comprises following component by weight: 1 part of chitosan, 1 part of acrylamide, 0.5 part in vinylformic acid, has the reticulated structure of coupling hardness with softness by the prepared acrylamide grafted copolymer of this proportioning raw materials, it can be gone up from different directions catch simultaneously suspended particles, obtain easily larger flco.When processing drinking water, the formation of flco is fast, large and closely knit, and settling velocity is fast, and the turbidity removal rate of tap water is reached 98.53%.
This clean reagent in drinking water adopts the method for natural polymer graft copolymerization acrylamide, and compound other sorbent materials to the person poultry harmless purify water, have reached the purpose of water purification, and the tap water after purifying does not contain harmful aluminium element.This clean reagent in drinking water portably uses conveniently, can solve because of Rural water supply dispersion, the little problem that is difficult to purify of service discharge.This clean reagent in drinking water use cost is cheap, do not have generation of waste materials, and the water after purifying through this clean reagent in drinking water can directly reach the standard of tap water, detects by GB/5749-2006, all meets the requirements.Simultaneously, the method for preparing this clean reagent in drinking water is simple and convenient, easy handling.
