Abstract
The invention relates to water treatment flocculant. The water treatment flocculant comprises, by weight, 8-15 parts of poly-aluminum ferric silicate sulfate, 3-8 parts of chitosan, 4-10 parts of water glass, 5-8 parts of aluminum sulfate and 5-12 parts of ferric chloride. The components are added into water according to the above ratio and can effectively remove impurities and suspended solids in the water, flocculation is quick and treatment effect is good. The water treatment flocculant is high in removal rate of various metal ions in the sewage and can effectively lower color and turbidity of water so as to let water quality conform to higher requirements. The flocculant is added once during use, and operation process is simplified. The quality of the treated sewage is kept consistent, secondary waste of recoiling and dirt suction is reduced and water and energy are saved. The water treatment flocculant can be widely applied to various types of sewage, such as from steel and chemical industry, power, printing and dyeing and domestic sewage.
Description
Technical field
The present invention relates to water-treatment technology field, particularly a kind of water treatment flocculant.
Background technology
Along with the develop rapidly of economy and improving constantly of the industrialization level of urbanization, industrial water consumption and quantity of wastewater effluent are also progressively increasing.The consequent is exactly the problem such as short water supply and water pollution.Protection and rational utilization of water resources become the major issue of people's common concern.A few years from now on water supply gets and sewage purification will become one of China and even main bugbear of facing all over the world.80 countries accounting for world population sum 40% at present are being faced with serious water shortage problem, and situation also can be continuous worsening.Through for many years to the research of water treatment method, wastewater treatment in China technology has achieved certain progress, defines the treatment technology of numerous species, comprises physics, chemistry, biology and comprehensive treatment technique.Chemical precipitation method is one of gordian technique of sewage disinfection treatment, determines the operation condition of follow-up flow process, effluent quality and operation expense.
Along with the increase of discharged volume of industrial waste water and the intensification of pollution level, single aluminium salt or Ferric Salt Flocculants cannot meet the water quality requirement of Industrial Wastewater Treatment, and the development of efficient compound polymeric flocculant is gradually by people are paid attention to.
Such as, application number be 200610035851.5 Chinese patent literature disclose a kind of preparation method of effective flocculating agent for paper making waste water, this flocculation agent makes water glass silicify alive by Tai-Ace S 150, make Tai-Ace S 150 aggregate into polyaluminium sulfate by the alkalescence of water glass simultaneously, make the two that synergy occur and form flocculation agent.The preparation process reaction of this flocculation agent not exclusively, and single low molecule inorganic flocculating agent has flocculation sediment speed is slow, amount of consumption of drugs is large shortcoming, and this flocculation agent is poor for the clearance of heavy metals in industrial wastewater ion.
Such as, application number be 201210182839.2 Chinese patent literature disclose a kind of compound drug of Treatment of Wastewater in Coking, be made up of following material: 100 parts, sodium sulfate, Tai-Ace S 150 350-450 part, water 15-25 part, bodied ferric sulfate 50-100 part, activated silicic acid sodium 500-100 part, chitosan 2-8 part.This medicament using Tai-Ace S 150 as main component, by composite to have COD clearance high with other materials, the feature of good decolorizing effect.But effect is removed not quite and do not possess disinfection for the metal ion in trade effluent.
Summary of the invention
Technical problem to be solved by this invention is to provide one effectively can remove impurities in water, suspended substance and each metal ion species, reduces a kind of composite high-molecular water treatment flocculant formula of secondary pollution.
For achieving the above object, the present invention realizes by the following technical solutions:
A kind of water treatment flocculant, each component is by weight ratio:
Every part of medicament of above-mentioned weight can process 0.3 × 10
8~ 1.0 × 10
8the water of part.
Preferably, a kind of water treatment flocculant, each component is by weight ratio:
Every part of medicament of above-mentioned weight can process 0.5 × 10
8the water of part.
A kind of water treatment method of water treatment flocculant: concrete operations are as follows:
(1) by said ratio, polymeric aluminium ferrum silicate and Tai-Ace S 150 are added respective weight 4-8 water doubly respectively, be prepared into solution, stir;
(2) chitosan is dissolved in the acetum of 1%;
(3) iron(ic) chloride is joined in deadweight 2-5 water doubly, stir and fully dissolve.
(4) join after solution mixing obtained by described step 1, step 2 and step 3 in pending water, and the water glass adding said ratio is mixed together, and stirs;
Compared with prior art, the invention has the beneficial effects as follows:
The present invention is main component with polymeric aluminium ferrum silicate, and in formula, institute's with medicament is all safety non-toxics, is easy to buy, and dispensing process is simple and convenient.Polymeric aluminium ferrum silicate is polymer inorganic flocculating agent, its bonding is assembled, high adsorption capacity, there is the dual function of flocculation and sterilization, the flco that can increase sedimentation composite with the inorganic flocculating agent such as ferric sulfate, iron(ic) chloride, accelerate settling velocity, adding of water glass can form synergy system with the two, doubles to improve flocculating effect.Chitosan has porous globule, and heavy metal has sequestering action, and after mineral-type flocculation agent compound, except flocculating effect improves, the consumption of chitosan also greatly reduces, and the concentration of the suspended substance in sewage and metal ion can be made greatly to reduce simultaneously.The amount of sludge that this flocculation agent has generation is few, and settling velocity is fast, and solidifying agent flco is closely knit, and adsorptive power is strong, can reduce the turbidity of water fast, the feature high to metal ion clearance, and have disinfection.
This formula flocculation agent use procedure is disposable dosing, and simplify the operation technique.
Use the sewage of flocculation agent process of the present invention, the water quality hold-time is long, decreases recoil and inhales dirty etc. secondary waste, economize on water energy-conservation again.
Flocculation agent of the present invention is applicable to the chemical wastewaters such as process iron and steel, chemical industry, electric power, printing and dyeing, and sanitary sewage, water of river and lake etc.
