Description
[technical field]
The present invention relates to a kind of sewage catalyst technical field, be specifically related to a kind of technical field of Catalysts and its preparation method.
[background technology]
Well-known water pollutes the pollutant that is mainly produced by mankind's activity to be caused, and it comprises industrial pollution source, agricultural pollution source and domestic pollution source three parts.Characteristics such as industrial wastewater is the important pollution sources in waters, and the amount of having is big, wide, complicated component, toxicity big, be difficult for purifying, difficult.Show according to water resources in china communique data in 1998: this year, totally 539 hundred million tons of national wastewater emission amounts (not comprising fiery constant current cooling water), wherein, 40,900,000,000 tons of discharged volume of industrial waste water account for 69%.In fact, water amount of blowdown is considerably beyond this number, because many township enterprises trade effluent discharge capacity is difficult to statistics.Agricultural pollution source comprises excrement of animals, agricultural chemicals, chemical fertilizer etc.In the pesticide sewage, the one, organic matter, plant nutrient and pathogenic microorganism content height, the 2nd, agricultural chemicals, chemical fertilizer content height.China does not carry out the monitoring on the agriculture face at present, shows according to interrelated data, and on 100,000,000 hectares of arable lands and 2,200,000 hectares of grassland, annual 110.49 ten thousand tons in the agricultural chemicals that uses.China is one of country of punishing severely most of soil erosion in the world, about 5,000,000,000 tons of the native number of dropouts of annual table, cause a large amount of agricultural chemicals, chemical fertilizer to flow into river, river, lake, storehouse with table soil, the nitrogen of Liu Shiing, phosphorus, potassium nutrition element thereupon, make 2/3 lake be subjected to the harm of eutrophication pollution in various degree, cause algae and other biological to breed unusually, cause the variation of water transparency and dissolved oxygen, thereby cause water quality deterioration.Domestic pollution source mainly is the various washing agent that use in the urban life and sewage, rubbish, ight soil etc., mostly is nontoxic inorganic salts, and nitrogenous in the sanitary sewage, phosphorus, sulphur are many, and malignant bacteria is many.According to investigations, China's sanitary sewage discharge capacity in 1998 is 18,400,000,000 tons.China has 1/3 industrial wastewater and the 90% above unprocessed waters that just enters of sanitary sewage every year approximately, the whole nation has in more than 1200 river of monitoring, present more than 850 are polluted, urban waters more than 90% is also polluted, cause the disappearance of many sections fishes and shrimps, meet country-level and the river secondary water standard only accounts for 32.2%.Pollute and just developed to deep layer by shallow-layer, underground water and territory, coastal waters seawater are also polluted, and the water that we can drink and use reduces unawares.And along with the level of urbanization of China improves and industrial expansion, trade effluent and city domestic sewage are more and more serious.
And traditional sewage disposal is generally drawn sewage toward collecting-tank, to collecting-tank end one style joint pH, rise to the first class pressure dissolving with one-level dissolved air water pump, suck air and coacervation decolorizer simultaneously, will be discharged into the one-level flotation tank at the one-level saturated dissolved gas water in the first class pressure dissolving suddenly and form one-level processing water; One-level is handled water and is overflowed into Buffer Pool, one-level being handled water at control pH with secondary dissolved air water pump again is promoted in the secondary pressure dissolving, suck air and coacervation decolorizer simultaneously, the secondary saturated dissolved gas water in the secondary pressure dissolving is discharged into the secondary air-floatation pond suddenly forms secondary treated wastewater and discharge from overflowing to the sedimentation basin post precipitation; Mud scum in the I and II flotation tank is gone into the mud scum pond, and press filtration becomes filter cake, and filtrate returning causes collecting-tank.This processing method often needs long time and more complicated flow process just can reach discharging standards water quality.
[summary of the invention]
For solving above deficiency, the invention provides a kind of a kind of Catalysts and its preparation method that is applicable to sewage disposal, catalyst by the preparation of this method can be effectively and the heavy metal ion in the sewage and its reaction of organic matter, and clean effect is obvious, has very strong practical function.
The problem to be solved in the present invention is how to add a kind of catalyst can effectively remove heavy metal ion and the organic matter that is rich in the sewage in sewage, making sewage reach discharging standards enters natural environment and does not make water system ecological deterioration and this method for preparing catalyst.
A kind of Catalysts and its preparation method takes by weighing the 1KG carrier active carbon, remove impurity and dust with clear water, take by weighing ferric nitrate 70G, nickel nitrate 60G, manganese nitrate 30G, potassium nitrate 10G, sodium metavanadate 30G, cobalt nitrate 30G, cerous nitrate 60G, ammonium molybdate 80G, chromic nitrate 20G, platinum 0.5G, golden 0.5G mixed dissolution, then cleaned active carbon being put into the solution for preparing flooded 48 hours, slaine is fully absorbed by active carbon, dry after dipping is good, put into the baking oven hot setting after drying, the nature cooling of coming out of the stove that solidifying finishes, the finished product that sieves then is packaged into the storehouse.
Described a kind of Catalysts and its preparation method is characterized in that described molten metal dip time is 36 hours-48 hours.
The temperature that described a kind of Catalysts and its preparation method is characterized in that putting into the baking oven hot setting is 280 degree-320 degree, and the time of hot setting is 12-15 hour.
