Abstract
The present invention relates to a pollution removing medicine for drinking water, particularly to a high-ferrum and high-manganese compounding medicine. The present invention is composed of components of the weight percentage: 0.1 to 90% of ferrate, 0 to 70% of permanganate and 0.1 to 30% of assistants. The present invention can be stored for a long time. Because permanganate and stable ferric salt are contained in the compound medicine, the good catalytic oxidation action and the good synergistic action among all components in the high-ferrum and high-manganese compound medicine and the specific property of the ferric salt (+6 valence) in water can be fully performed. The ferric salt (+6 valence) can oxidize and destroy organic substances, and the reaction product is ferric salt (+3 valence), which has no side effect to a human body. Coagulant with good efficiency can be generated to absorb colloid impurities and organic substances. Thus, the effects of enhancing coagulation and filtration can be obtained.
Description
Technical field:
The present invention relates to a kind of medicament that is used for the tap water depollution, particularly a kind of compound tap water depollution medicament.
Background technology:
Recent two decades comes, tap water depollution technology becomes one of focus of water treatment research, the employing method generally is to add organic pollutant in the methods removal water such as absorption method, Biological Pretreatment, chemical pre-oxidation treatment on existing conventional treatment process basis in the at present extensive water technology, in the hope of obtaining safety, qualified tap water.Wherein chemical preoxidation is one of wherein important technology, has the advantage of economical and efficient.The oxygenant that pre-oxidation treatment technology adopts at present mainly contains Cl
2, O
3, ClO
2, KMnO
4, H
2O
2Deng, it is few that chemical pre-oxidation treatment advantage is taken up an area of, and the reaction times is short, generally is subjected to Temperature Influence smaller, and their shortcoming is: some oxygenant (O
3, ClO
2) can not preserve, need on-site preparation, complicated operation; Expense costliness (O
3); Present result of study is thought, some oxygenant (Cl
2, O
3Deng) with water in organism reaction in, produce harmful by product.These methods both can be used separately, also can and require according to condition of water quality to adopt and other treatment process coupling, so often can obtain better treatment effect.The environment protection of China is backward relatively and funds are relatively limited, has determined that to reinforcement and the advanced treatment of contaminated drinking water source in water treatment process all be an important task in quite over a long time.The polluted water strengthening treatment process of wherein seeking economical and efficient has very important meaning for today China national conditions and polluted-water.
Summary of the invention:
The purpose of this invention is to provide a kind of tap water depollution medicament, it is enhanced coagulation, intensive filtration in polluted water is handled, have efficient, safety, economy,, easy handling management little and realize that automatic control advantage, this technology are the strengthening treatment process that China goes out in tap water depollution field independent studies temperature and organic loading variable effect.Tap water depollution medicament of the present invention is made up of following component in percentage by weight: ferrate 0.1～90%, permanganate 0～70% and assistant agent 0.1～30%.Tap water depollution medicament can be made up of following component in percentage by weight optimization: ferrate 20～45%, permanganate 40～60% and assistant agent 10～30%.High ferrimanganic compound (CFP) can be preserved the long period.Owing to contain permanganate and comparatively stable ferric salt composition in the compound, thereby given full play to good catalyzed oxidation and the synergy between various compositions in the high ferrimanganic compound (CFP), and ferric salt (+6 valency) reacts distinctive character in water: oxidation and destruction organism, reaction product is originally as molysite (+3 valency), without any side effects to human body, generate the good coagulating agent of usefulness, adsorb colloidal impurity and organism, reach the effect of enhanced coagulation, intensive filtration.High ferrimanganic compound (CFP) itself is natural sterilizing agent, can make full use of its high price strong oxidizing property break virus and bacterium, and from present result of study, its deactivation efficient is better than HClO and OCl
-, the generation of sterilization accessory substance is much smaller than disinfection byproduct (DBP) that chlorine disinfectant produced.High ferrimanganic compound (CFP) in enhanced coagulation, intensive filtration, removal turbidity, colourity, algae, smell flavor, remove micro quantity organic pollutant and mutagenesis active substance in the water, reduce haloform antecedent and haloform growing amount, replace prechlorination, reduce and have excellent performance aspect the consumption of coagulating agent, its a lot of aspects of depollution performance surpass ozone pre-treatment depollution effect, precipitate simultaneously and filter after water in bacterium almost be killed.Using at present chlorine only to add a spot of sterilizing agent in the output water under as the condition of sterilizing agent, just can keep the wholesomeness of output water in outer net, avoid disinfection byproduct (DBP) to produce in a large number.
