Abstract
The present invention discloses a synergistic agent for water processing, which relates to a water processing agent, more specifically a synergistic agent for water processing. Aiming at the problem that the content of aluminium ions in drinking water exceeds the standard, the synergistic agent for water processing of the present invention is composed of sodium carboxymethyl starch and guar gum/xanthan, wherein the weight percentage of the sodium carboxymethyl starch and the guar gum/xanthan is (7.5 to 9.5) to (0.5 to 2.5). The present invention applies different functional groups to change different chemical properties through derivative chemistry, and simpler atomic groups The synergistic agent for water processing of the present invention is white powder which is innocuous and tasteless and has high synergic effect and easy use; water purifying agents and the synergistic agent are mixed and added in water when the synergistic agent for water processing is used; by using the synergistic agent, the water processing cost is greatly reduced, and the problem that the content of aluminium exceeds the standard is solved.
Description
Technical field:
The present invention relates to a kind of water conditioner, be specifically related to a kind of synergic agent in use for treating water.
Background technology:
At present, in water treatment, generally adopt the aluminium salt as water purifying agent both at home and abroad.But aluminum ion can disturb nutritive element essential in the human body and trace element displacement or deposition, destroy the human organ physiological function after exceeding standard and entering human body in the water, causes occurring poisoning illnesss such as aluminum encephalopathy, osteopathy, aluminium anaemia.Therefore, WHO for a long time in the regulation tap water aluminium content be limited in 0.2mg/L, and aluminium content mean value is 0.29mg/L in the Drinking Water in China, handling also only is 0.23mg/L preferably.
Summary of the invention:
The problem that exceeds standard at aluminum ion in the tap water, the invention provides a kind of synergic agent in use for treating water, it is made up of (1) sodium starch glycolate and (2) guar gum and/or xanthan gum, and its weight ratio is a sodium starch glycolate: guar gum and/or xanthan gum=7.5～9.5: 0.5～2.5.
The present invention is a raw material with sodium starch glycolate, guar gum, xanthan gum, wherein sodium starch glycolate is a kind of of modified starch, be white or pale yellow powder, feel is than sodium starch glycolate (CMC) uniform and smooth, have stronger suction and water-swelling, higher viscosity and bigger clinging power, its flowability, solvability, emulsifying property, stability and permeate well, and difficult corruption is gone mouldy.Sodium starch glycolate has negative charge, is the water-soluble polymer electrolyte of a kind of energy.In water treatment, be used as flocculation agent and ion exchange resin etc.
Guar gum, the another name guar gum, be by glycosidic linkage bonded Polygalactan, the i.e. high molecular hydrocolloid polysaccharide of forming by semi-lactosi and seminose (1: 2), molecular weight is about 20～300,000, it be white to the light tan free flowing powder, can be dissolved in fully in cold water and the hot water, its aqueous solution is tasteless, odorless, nontoxic, be neutral.Owing to contain a spot of fiber and Mierocrystalline cellulose in the solution, it is translucent therefore to be light gray.Aqueous guar glue solution has high viscosity, its viscosity size and particle size, pH value are relevant with temperature, generally at room temperature in water through 24 hours or under 80 ℃, handled through 10 minutes, obtain concentration and be 1% solution, viscosity is 3.0～6.0Pas, be natural gum medium viscosity soprano, its thickening capabilities is higher 4～7 times than starch.Guar gum solution is stable in pH value 4.0～10.5 scopes, and hydration is the fastest when pH value 8.Guar gum and other plant glue, starch and water soluble protein etc. have intermiscibility, and can present the tackify synergistic effect after xanthan gum is mixed.In water and wastewater treatment, use guar gum and derivative thereof to make flocculation agent.
Xanthan gum is a kind of biopolymer polymkeric substance, and " the pentasaccharides repeating unit " be made up of d-glucose, carubinose, d-glucuronic acid, acetate and pyruvic acid is polymerized.Xanthan gum is tasteless, and is soluble in water for faint yellow free-flowing powder, can dissolve each other with methyl alcohol, ethanol, Virahol and acetone.Xanthan gum solution can present high viscosity under lower concentration, and along with the increase viscosity of concentration obviously improves, shows good thickening property.Xanthan gum solution also has distinctive rheological, present the height pseudo-plasticity, promptly when the increase solution shearing rate the time, soltion viscosity reduces, this phenomenon be moment and also be reversible.When xanthan gum solution concentration greater than 0.75% the time, exist a vacation to mould yield-point.For concentration is 1% solution, and when shearing rate was 0.001l/s, its yield point value was 50mN/m.Xanthan gum has good thermostability, and particularly when small amount of electrolyte existed, viscosity remained unchanged substantially in-18～80 ℃ of temperature ranges.In salts solution, xanthan gum can be anti-105 ℃, under certain conditions can be heat-resisting 140 ℃.Xanthan gum is dissolved in bronsted lowry acids and bases bronsted lowry, and its viscosity can keep stable in the several months under certain condition.In the scope of pH=1.5～13, its viscosity number is constant, is not subjected to the influence of pH value.Xanthan gum and most of salt dissolve each other, and many high salt concentrations have good intermiscibility and stability as 15% sodium-chlor and 25% calcium chloride solution and xanthan gum.Have only polyvalent metal ion to cause pectisation or under high pH value, produce precipitating action jointly with xanthan gum.Another special performance of xanthan gum is to work in coordination with the tackify effect with galactomannan sugar as guar gum and the Chen Sheng of Viscogum BE interaction institute.When xanthan gum combines with guar gum, can obtain the viscosity higher, and not form gel than guess value.In going out to handle, xanthan gum is as flocculation agent and other flocculation agents or additive compatibility use, and in water purification, particularly effect is obvious in the purifying treatment of tap water.
The present invention uses different functional groups and changes different chemical property by the chemistry of deriving, and is replaced by other atomic groups and is generated than complicated compound by better simply atomic group.Synergic agent in use for treating water of the present invention is white powder, and is nonpoisonous and tasteless, and the synergy height is easy to use.Water purification agent mixes with synergistic agent and adds during use, uses this synergistic agent not only can reduce the water treatment expense significantly, and has solved the difficult problem that aluminium exceeds standard.With the polymerize aluminum chloride is example, majority all was to adopt polymerize aluminum chloride as water purification agent when general water factory handled hydrostatic, the use of polymerize aluminum chloride has increased running cost on the one hand, on the other hand the aluminium poisoning illnesss such as can causing occurring aluminum encephalopathy, osteopathy, aluminium anaemia that exceeds standard.Synergistic agent of the present invention is a starch property, self can not produce precipitation in the treating processes, itself and polymerize aluminum chloride are mixed use, the usage quantity of polymerize aluminum chloride is reduced to 1000 tons by original 1500 tons, and 500 tons of synergy have not only improved processing efficiency, reduced aluminum ions content in the water, make cost reduce by 1/3rd, and can shorten the settling time, just can make muddy treating water become clarification within 30 seconds.
