Characteristics; scale inhibiting, disinfecting, weed eliminating, corrosion inhibiting etc. at the same time.
Description
The common water treatment method that uses in a kind of high molecular water treating chemical and magnetic field.
The present invention relates to the treatment process of water, particularly the purification and the processing method of industrial waste water of industrial equipments cycling use of water, heating water, agricultural water.
At present, water treatment method has formed the treatment technology of numerous species through research for many years, and physics, chemistry, biology and comprehensive treatment technique are arranged.In the purifying treatment of industrial equipments cycling use of water, heating water and agricultural water, the physics fado adopts methods such as ion-exchange, filtration, electric field, magnetic field and optical processing, when water pollution is relatively more serious, and the treatment effect instability of these methods; Chemical method need add a large amount of chemical agents, and the input of various medicaments itself is also brought water pollution once again.Simultaneously, also can influence each other, have side effects and influence comprehensive treatment effect for solving between the medicaments that problem added such as fouling, corrosion and bacterium algae.Physical-chemical-biological synthesis treatment technology is adopted in relevant wastewater treatment more, and this method investment is many, and facility is big, the working cost height.Application number 93110046.1 patents of invention disclose a kind of magnetic field treatment and coefficient water treatment method of chemical treatment and device.This method is at the equipment water, employing be before water treatment, to add alkaline matter NaOH or Na
2CO
3, it is 7.5～11.5 that water quality is transferred to the pH value, hardness value is passed through magnetic field treatment again less than 7mg/L, reaches to prevent equipment scaling, helps the rot-resistant purpose.But this method does not have the purification and impurity removal process, so be not suitable for seriously polluted, as to contain the higher trade effluent of mixing processing, does not reuse purpose thereby reach.This method only is owing to add alkaline matter to the rot-resistant beneficial effect, reduced due to the acidity of the aqueous solution, thereby the range of application of this method is subjected to certain restriction.
The object of the invention is to provide a kind of effect stability, pollutes for a short time, and operation is convenient, less investment, the water treatment method of applied range.
The object of the invention is achieved through the following technical solutions:
Adopt high molecular water treating chemical and magnetic field acting in conjunction, add inorganic or organic polymer water treatment agent or the two common use according to the water quality particular case, under the action of a magnetic field behind the coagulation, the sand filtration of process purifies the water outlet that obtains, again through magnetic field compose behind the magnetic with solution in dissolved small molecules group synergy, finally be reached for the purpose that various device provides water.Feature of the present invention is the synergy that has mutual reinforcement between magnetic field treatment and the polymer medicament.
For reaching preferable treatment effect, at first suspended solid, metal ion, organism and bacterium algae in the water quality of former water are analyzed, and, determined the add-on of medicament, the action of a magnetic field intensity and concrete technology in conjunction with the quality of water requirement.
The inorganic polymer medicament that adds can be the polymkeric substance of aluminium, iron or the common polymkeric substance of ferro-aluminum; Organic polymer can with the natural phant modified high-molecular or have the composite polymer of groups such as polysaccharide, acid amides, silica and similar molecular weight distribution at 100,000 to 1,000,000 polymer medicament.
Can suitably improve the inorganic polymer consumption for what water required slant acidity, according to different water quality different adding scopes can be arranged, usually in 1mg/L～10mg/L scope; For
Water requires to be the situation of meta-alkalescence, can suitably improve the add-on of organic polymer medicament, generally in 0.1mg/L～2mg/L scope.
Positively effect compared with prior art:
The coagulation process that at first is the polymer medicament under the synergy of magnetic field, this will help molecular weight major part group formation flco in suspended substance, metal ion and bacterium algae substances and the polymer in the water body, remove after filtering.The less group of molecular weight is dissolved in the water body in the polymer, under the synergy in magnetic field with the calcium ion complexing, play scale effect, and also form the fine and close compound film that contains iron ion and play corrosion inhibition on the surface of metallic conduit, so the present invention has purification, scale inhibition, sterilizing and algae-removing and corrosion mitigating effect, owing to reduced the add-on of chemical agent, reduced hazard rating to environment.
Fig. 1 is a process flow sheet of the present invention, and its explanation can be referring to the embodiment that provides.
Embodiment 1: wastewater treatment is as industrial water supply refinery effluent main component (mg/L): COD:300; PH=7.6; Heavy metal ion＞23mg/L; Turbidity 52NTU.
Add medicament bodied ferric sulfate 8mg/L, macromolecule modified medicament CMS of natural phant or CGA3mg/L are through the magnetic field of 0.4T, after flow 5ml/min handles, stirred 20 minutes, and static 20 minutes, filtered back supernatant liquor turbidity 1.6NTU, COD:45, heavy metal ion＜0.06mg/L, the pH value is 8.3.Carry out the magnetic field treatment of 0.5T again.The last test result is: scale inhibition performance 92%, and sterilizing rate 93%, corrosion inhibition rate 97% meets the standard of industrial circulating water, can be used as the industrial equipments water coolant and uses.Embodiment 2: the surface water is handled as industrial water supply original ground water: the pH value is 7.06; Turbidity 8.2 NTU; 2,300,000 in algae.The test medicine add-on is: the inorganic polymer medicament is polymerize aluminum chloride 2mg/L～10mg/L, and the organic polymer medicament is polyacrylamide and 1: 1 composite 0.1mg/L～2mg/L of active silicic acid, and magnetic field treatment intensity is 0.1～0.8T.The pH value of filtering back water is greater than 8, and through the 0.5T magnetic field treatment, test-results sees Table 1: table 1 again: the experiment decontamination effect improving
As can be seen from Table 1, scale inhibition, sterilization and corrosion mitigating effect are: scale inhibition performance 76%～98%, and sterilizing rate 75%～93%, corrosion inhibition rate 78%～96% meets the industrial circulating water standard, can be used as the industrial equipments water coolant and uses.
