The advantage of the poisonous organic pollutant waste water of difficult degradation is got rid of separately to the absorption constructed wetland of this system and little electrolysis technology, carries out the coupling with both, reaches the purpose of effectively getting rid of the pesticide pollution thing in the same system.
Description
Technical field
The utility model belongs to environmental engineering ecological wastewater processing technical field, specifically a kind of vertical artificial wet land system of upwelling processing widespread pollution from the overuse of fertilizers and pesticides in rural area, it not only controls for the nitrogen and phosphorus pollution in widespread pollution from the overuse of fertilizers and pesticides in rural area, and the farm chemical ingredients carried in widespread pollution from the overuse of fertilizers and pesticides in rural area runoff is effectively degraded, avoid the formation of agricultural chemicals secondary pollution.
Background technology
Agricultural chemicals, as a kind of important capital goods in the agricultural sector, is produced at protecting agriculture, is improved overall productivity in agriculture, protecting agriculture ecotope, promotes, on stable food volume increase and Practices Sustainable Increasing Income of Farmers, to play extremely important effect.China is pesticide producing big country and Pesticide use big country.A large amount of uses of agricultural chemicals are on the one hand for significant contribution has been made in agriculture production, but the utilization ratio of agricultural chemicals only has 10% ~ 20%, all the other can with rainwater or irrigation water to water body migration or form droplet or dust particle enters water body with wind drift sedimentation in Pesticide use process.Because toxicity of pesticide is strong, large, the Residual time of residual quantity and biological half time long, can concentrate through food chain, and can circulate in the environment and put aside, cause severe contamination to ecotope.
Agricultural chemicals in agriculture production causes pollution of area source to affect by agricultural runoff on water surrounding, the mechanism that its waste water produces is complicated, traditional treatment technology is difficult to be suitable for, and the pollution of area source problem that various countries bring because of agricultural run-off artificial swamp improvement is own through having carried out many Study and appliance.Artificial swamp is the Novel sewage process that grows up of 20 century 70s and aquatic ecological restoration technology, normal for by soil or hand-stuff (as rubble etc.) and grow waterplant thereon the soil-plant-microorganism-animal ecology system of uniqueness that forms.The decomposition of microorganism in artificial wet land system, utilization, alienation, the absorption of matrix, filtration, and the process such as the absorption of plant, conversion all likely plays the effect of purification to the insecticide pollution in water body.
Although artificial swamp is as a kind of effective means of process agricultural effluent, through progressively improvement for many years, many application examples also all show effectively to process sterilant in agricultural runoff and weedicide with artificial swamp.Artificial wet land system effectively one of mechanism removing agricultural chemicals is exactly retain the suspended particle adsorbing agricultural chemicals in agricultural runoff, the biodegradability different according to agricultural chemicals, and agricultural chemicals composition residual semi-invariant in artificial wet land system settling changes thereupon.Organochlorine pesticide and sulfur-bearing organophosphorus pesticide such as parathion-methyl, pririmiphos_methyl, Profenofos, Rogor, Malathion etc. are not easily degraded by microorganisms, and biodegradability is poor, and biological half time is long.These characteristics determine insecticide pollution and can put aside for a long time in artificial swamp settling, in the settling of especially anaerobic state.When rainy season, heavy rain can wash away artificial wet land system the settling of the difficult degradation agricultural chemicals of accumulation, causes the secondary pollution to environment.In addition, the agricultural effluent being rich in agricultural chemicals has larger bio-toxicity, difficult degradation, complicated component.
In recent years, the optimum combination of artificial wet land system and other treatment technology becomes the study hotspot of New Wastewater Treatment Technology art.Using Zero-valent Iron (as sponge iron, iron filings, iron plane flower) as artificial swamp fraction matrix layer, and the hypothallus such as gravel, sand, red soil builds Zero-valent Iron coupling artificial wet land system; Also have with iron filings, flyash, slag composition micro-electrolysis stuffing composition artificial swamp matrix, form the combination of light electrolysis and artificial wet land system, achieve the object effectively removing Pollutants in Wastewater.But this type of zeroth order iron layer and micro-electrolysis stuffing layer are easy to harden and passivation, thus cause artificial swamp hypothallus to block, affect the normal operation of artificial swamp greatly, bring higher cost to maintenance.
Micro-electrolysis method sewage disposal technology utilizes Principles of Metal Erosion, forms the good process that galvanic cell processes waste water.Micro-galvanic cell that it makes full use of iron-charcoal System forming processes Recalcitrant chemicals in water, improves the biodegradability of hardly degraded organic substance.Its mechanism mainly comprises: the adsorption of (1) iron filings; (2) reductive action of Fe; (3) light electrolysis product Fe
2+, hydrogen reductive action; (4) Fe
2+/ Fe
3+throwing out.During Fe-C Micro Electrolysis Method process agricultural chemicals waste water, dominant mechanism has: electrochemistry enrichment, redox, physical adsorption, iron ion coagulation.Fe-C Micro Electrolysis Method effectively can remove the colourity of pestsides synthesis waste water, smell and suspended substance, can reach about 42% to the clearance of chemical oxygen demand COD, reduces subsequent treatment cost and load.As added a certain amount of Mn in iron-carbon system
2+and Zn
2+, make it to be adsorbed in activated carbon surface, the organic effect of certain catalyzed oxidation can be produced, be conducive to producing throwing out, obtain good agent effective.The process of Fe-C Micro Electrolysis Method to acetochlor and Monocrotophos Pesticides waste water is also very effective, the COD of waste water
crclearance can reach more than 67%.Employing iron filings and coke are the micro-electrolysis treatment agricultural chemicals waste water of filler, COD
cr, colourity, As, ammonia nitrogen, organophosphorus and total tp removal rate can reach 76.2%, 80%, 69.2%, 55.7%, 82.7% and 62.8%, the BOD of waste water respectively
5/ COD
cr(biodegradability) brings up to 0.5 from 0.29.
If using iron-carbon micro-electrolysis filler as a part for the matrix components of artificial swamp, by light electrolysis and artificial wetland process coupling, the detergent power of system of light electrolysis artificial swamp association to insecticide pollution can be strengthened, micro electrolysis tech is utilized to destroy the chemical structure of organic pesticide, realize the open loop of organic pollutant, chain rupture, improve the bio-degradable of waste water.Utilize simultaneously Plants of Constructed Wetlands, microorganism synergy residual organic substances is thoroughly degraded.In addition, microelectrolysis process produces the secretion that iron ion can promote microbial reproduction and enzyme, not only can significantly improve Nitrogen removal effect, also help the phosphorus in purifying waste water.
