Abstract
The composite water pollutant eliminating chemical preparation consists of permanganate, silicate polymer and adjuvant. The composite water pollutant eliminating chemical preparation contains natural sterilizer and the powerful oxidation property may be utilized to destruct viruses and bacteria, generating less side sterilizing product. The present invention has raised coagulation and filtering effects for eliminating turbid matter, color, algae, bad smell, organic pollutant, mutagenic matter, etc.
Description
Technical field:
The present invention relates to a kind of water treatment depollution medicament.
Background technology:
China's seven big major river valley surface water organic contaminations at present are generally serious day by day, and the kind of pollutent is increasing, and pollution of waterhead is challenged to existing water purification technology.Data presentation, existing purification techniques can not guarantee the security of drinking water quality.In the coagulation-settlement process link, water-borne glue body particle is difficult to take off surely, and the dosage of coagulating agent increases greatly, and organic pollutant is difficult to remove from water, and cost of water treatment rises significantly.In the filtration process link, organic increase in the water causes the filter material surface in the filter tank to be subjected to organic pollution, and surface properties changes, partly or entirely lost absorption and crown_interception, filtered and greatly weaken as the crucial barrier action in the technology to colloidal impurity.Turbidity, organic pollutant do not obtain effectively catching in filtration procedure.In the sterilization process link,, thereby produce more disinfection byproduct (DBP) because aforementioned processing technology fails effectively to remove organic pollutant.Pollute under the comparatively serious condition at water, use coagulating agent to be not enough to sometimes organic removal is produced good effect separately, at this moment need to use various medicaments combined action reinforcing process, comprising: the material that adopts ozone, prechlorination, potassium permanganate, dioxide peroxide etc. to have oxidizing property carries out preoxidation, these pre-oxidation processes not only can be removed organism, can also reach enhanced coagulation, filtering purpose to the influence of colloidal solid by destroying organism.Adding various medicaments simultaneously needs two covers or the above system of two covers, and the operation management is comparatively complicated, and cost of equipment is also higher.Removing little pollution with ozone pre-oxidation is example, and for a medium-scale water factory (100,000 ton per day), investment reaches millions of to up to ten million units.Research shows that also some oxygenants such as ozone, chlorine etc. also can produce some by products removing organism simultaneously.Can work out a kind of economy, efficient, safety, the novel depollution compound that integrates enhanced coagulation, filtration and depollution, make it have the control of adding aspect and need a cover system, the convenient and simple advantage in operation operational management aspect, this processing to current Chinese polluted water has positive effect.Disclose a kind of " drinking water purifying technique with compound permanganate medicament " among the CN1103628A,, had many shortcomings such as waste equipment, control is complicated, effect is bad, molecular weight is little because permanganate composite chemical and coagulating agent need add respectively.
Summary of the invention:
The purpose of this invention is to provide a kind of economy, efficient, safety, integrate the water treatment compound of enhanced coagulation, filtration and depollution.Medicament of the present invention is made up of permanganate, silicate polymer, assistant agent, and their weight percent is: permanganate 0.1～50%, silicate polymer 0.1～35%, assistant agent 15～80%.Because the inorganic polymer material that contains permanganate and aggregate under certain condition in the compound by silicate, thereby synergy such as given full play to that the good oxidation between various compositions in the novel depollution medicament, catalysis, charge neutrality, absorption volume are swept.Permanganate (+7 valency) has oxidation and destroys organism, generates Manganse Dioxide absorption colloidal impurity and organism and plays catalysed oxidn, reaches the effect of enhanced coagulation, intensive filtration; The while ferric-polysilicate is brought into play the high molecular absorption volume of its high-valence cationic charge neutrality effect and silicate polymer own and is swept effect, and its molecular weight can reach 10
5～10
6Dalton, the ferric-polysilicate coagulating agent compares with organic polymer coargulator (polyacrylamide etc.) with the inorganic coagulant (Tai-Ace S 150, polyaluminium sulfate, polymerize aluminum chloride, bodied ferric sulfate etc.) that is using at present because nontoxic greatly, the advantages such as price is low, coagulation effect excellence of its molecular weight promise to be inorganic high fractionated molecule coagulating agent of new generation very much.Depollution medicament of the present invention itself contains natural sterilizing agent, can utilize its high price strong oxidizing property break virus and bacterium fully, the generation of sterilization accessory substance is much smaller than the disinfection byproduct (DBP) that chlorine disinfectant produced, and this medicament is removed turbidity, colourity, algae at enhanced coagulation, intensive filtration, smells flavor, removes micro quantity organic pollutant and mutagenesis active substance in the water, reduces haloform antecedent and haloform growing amount, replaces prechlorination, reduced the performance that has excellence aspect the consumption of coagulating agent.For example: this water treatment depollution compound is in the processing of the Huanghe valley four class water bodys experiment, and dosage is during in iron 5～8mg/l, only COD in coagulation-settlement process
MnJust can remove 70～80%, the clearance that nitrite nitrogen is all removed downstream, the Yellow River lake and reservoir algae and water can reach 90～95%, and chroma removal rate can reach 80%.To COD
CrConcentration is the trade effluent of 120～130mg/l, and dosage is only just removed COD during in iron 5～8mg/l in coagulation-settlement process
CrAbout 70～80%, reach industrial wastewater discharge standard and reuse standard substantially.
