Abstract
The invention discloses an underground water processing method, which comprises the following steps: adsorbing water through charring rice husk; coagulating; sedimenting; heating to boil; obtaining the product.
Description
Technical field
The present invention relates to a kind of combination treatment method of underground drinking water, be primarily aimed at and contain the phreatic processing of trace nitrobenzene, belong to the drink water purifying class.
Background technology
China's people in the countryside are numerous, and are sparsely populated, and mainly based on well water (underground water), the water source is subject to organic contamination, and drinking water safety causes anxiety.The villages and small towns in riverine basin particularly, in the process of river recharge groundwater, the organic pollutant in the river easily enters underground water, causes riverine dispersion tap water to be polluted.Because villages and small towns disperse tap water to lack the processing advantage of central water supply, wide point is many, restive simultaneously.So in today that drinking water safety comes into one's own day by day, exploitation is applicable to that villages and small towns disperse the multistage barrier treatment process of underground drinking water particularly important.
The present invention will provide a kind of underground drinking water combination treatment method, and this method can effectively be removed nitrobenzene organic pollutant, heavy metal and the ferrimanganic etc. of trace in the tap water, can reduce the effect of tap water bio-toxicity.It is simple that the present invention has method, and craft science is easy to draw materials, and easy to use, expense is cheap, the characteristics of safety and sanitation.
Summary of the invention
Combination treatment method of the present invention is as follows:
Get contaminated underground drinking water, add an amount of charring rice husk, evenly stirred 30 minutes, add an amount of coagulating agent, stirred 1 minute fast, stirred slowly 10 minutes, quiet then heavy more than 6 hours, get the supernatant liquor heating and keep boiling 3-10 minute, after the cooling, just can obtain safe tap water.
The combination treatment method each several part describes in detail:
Charring rice husk adopts the byproduct rice husk after the rice processing, cleans to remove sand, dries or dry the back after carrying out roasting on iron pan, iron plate or the potter's clay utensil, grinds to get final product, and granularity does not have strict demand.The purpose that adds charring rice husk is to utilize its bigger specific surface area and adsorptive power, and organic pollutants such as oil of mirbane, heavy metal and the ferrimanganic etc. in the water are removed in absorption.Exceed standard 5 times at oil of mirbane, promptly content is under the condition of 85 micrograms per litre, and the carbonization rice husk that adds 1.0 grams per liters gets final product.As long as add enough charring rice husks (seeing the following form), just can make nitrobenzene in the water be lower than the standard of drinking water source, i.e. 17 micrograms per litre oil of mirbane.Remove the required charring rice husk throwing of different concns oil of mirbane scale in the underground water
| Nitro phenenyl concentration (micrograms per litre) | 85 | 170 | 340 | 5100 |
| Charring rice husk throwing amount (grams per liter) | 1.0 | 2.5 | 4.5 | 50 |
Coagulating agent adopts polymerize aluminum chloride and iron trichloride to unite and adds, general throwing amount is the polymerize aluminum chloride of 40 mg/litre and the iron trichloride of 5 mg/litre, mainly play coagulation, so that the quiet heavy stage is effectively separated carbonization rice husk, organic pollutant, heavy metal and ferrimanganics such as the p-nitrophenyl of while coagulation own also have good removal effect.
Quiet heavy effect is that the carbonization rice husk and the water sepn of absorption oil of mirbane are come, and after supernatant liquor had been got, throw out carried out the nature mummification, burns with agricultural stalk then.
Ebuillition of heated adopts the general type of heating of villages and small towns family just passable, and what the water yield was bigger can adopt dwarf boiler.Boiling time can prolong according to the nitrobenzene in the water sample to be heated, generally be no more than 10 minutes in case in the water other materials become big because of concentrating concentration, influence composite water quality and mouthfeel.Ebuillition of heated itself can reach more than 80% the removal of oil of mirbane in the tap water.Oil of mirbane and water base belong to immiscible liquid, two kinds of liquid mutual solubility are minimum, after water is heated and seethes with excitement, from the angle that balances each other, oil of mirbane mutually and water have the fixed steam pressure of self, oil of mirbane just can be overflowed mutually and separates along with water vapor.
Embodiment
Get 10 liters of contaminated underground waters, the oil of mirbane that contains 85 micrograms per litre adds charring rice husk 10 grams that grind in water, evenly stirred 30 minutes with clean wooden stick or little spade, the iron trichloride that adds 400 milligrams of polymerize aluminum chlorides and 50 milligrams then simultaneously, stirred 1 minute fast, stirred at a slow speed 10 minutes, quiet then heavy spending the night, get supernatant liquor, heat with adding hot-water bottle, keep boiling 5 minutes, just can obtain the safe drinking water of nitrobenzene-containing hardly.Other organic pollutants, heavy metal and ferrimanganic etc. in the water also meet the water quality standard of tap water simultaneously.
Claims (3)
1, a kind of contaminated phreatic combination treatment method, comprise charring rice husk absorption, coagulating sedimentation and heating azeotropic treatment step, it is characterized in that: mainly trace nitrobenzene is a purpose in the water to remove, and order adopts charring rice husk absorption, coagulating sedimentation and azeotropic removal method.
2, according to a kind of contaminated phreatic combination treatment method of claim 1, it is characterized in that: utilize the agricultural by-products rice husk, the sorbent material of using as water purification after the charing.
