Description
Technical field
The present invention relates to a kind of sewage disposal technologies, especially a kind of reverse circulation ecological purification pool.
Background technology
China city, town, rural area, in the prevalence of contaminated lake pond, water quality much belongs to bad V class even
Black and odorous water, fly, mosquito multiply, and eutrophication is serious, bogginess accelerates, and damages ecological environment and living conditions.
The recovery technique used at present is roughly divided into following 4 class：
1. ecological reestablishment i.e. kind of planting submerged plant, emergent aquactic plant or floating plant.
2. retaining the pollution sources such as point source, face source.
3. extraction section polluted-water, after materializing strategy, feedback water body is diluted.
4. periodically displacement polluted water.
Above-mentioned 4 class recovery technique, or rest on the lab scale stage be difficult to large area productivity implementation；Or effect is difficult to tie up for a long time
It holds；Or the larger cost of investment is higher；Or object of transferring the pollution.
Invention content
The purpose of the present invention is to overcome above-mentioned the deficiencies in the prior art, provide a kind of reverse circulation ecological purification pool, be somebody's turn to do
Purifying pond uses the technology that physical cleaning, physico-chemical purification, ecological purification and biochemical purification are combined, by black and odorous water or
Bad V classes water remediation be cleaned into《Environmental quality standards》2002-06-01 surface water, III class even II class water standard.
To achieve the above object, the present invention uses following technical proposals：
A kind of reverse circulation ecological purification pool, in the waters of required processing, by the purse seine vertical with water (flow) direction by waters
It is divided into three regions successively, is followed successively by anaerobic zone, aerobic area and aerobic zone；
Emergent aquactic plant water lily kind is implanted in the anaerobic zone, the concentration of dissolved oxygen is less than or equal to 0.1mg/L；
The dissolved oxygen concentration of the aerobic area is 0.5mg/L；
It kind is implanted in the aerobic zone and carbonaceous organic material can be degraded to H2O and CO2, itrogenous organic substance is degraded to NH3- N, and plant
Be implanted with using in water body and bed mud nitrogen, phosphorus as nutrition, the submerged plant hydrilla verticillata of growth and breeding, eel grass and along loke shore kind
It is implanted with thaliadeabata.The concentration of aerobic zone dissolved oxygen maintains 4mg/L or more.
Trizonal water surface area ratio is：1: 4: 5.7；Water body volumetric ratio is 1: 7: 12.
The purification function of the reverse circulation, by clear water zone（Aerobic zone）Water reverse circulation to anaerobic zone and aerobic area,
Reverse circulation flow accounts for the 16~25% of clear water zone volume.Nitrification is completed in aerobic area, is nitrite by Ammonia Nitrification
NO2 -With nitrate NO3 -, anti-nitration reaction is completed by NO in anaerobic zone2 -With NO3 -It is reduced to nitrogen N2, achieve the purpose that denitrogenation.
Above-mentioned four classes purification function is formed into a complete ecological purification system.Cycle is continued for carbonization, ammonification, nitre back and forth
Change, denitrification.
Present invention employs the technology that physical cleaning, physico-chemical purification, ecological purification, biochemical purification system are combined,
By black and odorous water or bad V classes water remediation be cleaned into《Environmental quality standards》2002-06-01 surface water, III class even II class
Water standard.Achieve significant social benefit, environmental benefit, economic benefit and political benefit.

Nutrient for plants.
2. on the branches and leaves of black algae and eel grass breeding have biomembrane, can absorption, absorb water body in colloid and dissolubility it is organic
Object seeks biological chemistry action, the organic pollution in water body of degrading.
3. luxuriant branch, leaf seek photosynthesis, oxygen and free carbon dioxide are released, Dissolved Oxygen in Water can be increased and contained
Amount and raising pH value.
4. luxuriant branches and leaves can decay, typhoon, heavy rain hold together the leaching of water body, promote fine suspended particulate, colloidal substance
Sedimentation plays physical cleaning, reduces turbidity, increases transparency.
5. breeding active protozoan in water body（Paramecium, campanularian, tired branch worm, Didinium, Parapet fibre worms etc.）, after
Lively object（Wheel animalcule, nematode, few caterpillar etc.）, it is food with organic debris, Escherichia coli and free bacteria, keeps water quality more clear
It is clear transparent., the purification function of aerobic zone is that carbonaceous organic material is degraded to H2O and CO2, itrogenous organic substance is degraded to ammonia nitrogen NH3
N, and settle dephosphorization.
6. along the recyclable absorption clear water zone water body of the thaliadeabata of aerobic zone loke shore plantation, deep removal TP, TN and COD.
The purification function of reverse circulation：By the water of clear water zone by return water facility reverse circulation to anaerobic zone and aerobic area,
Reverse circulation flow accounts for the 16~25% of clear water zone volume, completes nitrification in aerobic area, is Ami nitrate by Ammonia Nitrification
NO2 -With nitrate NO3 -；Anti-nitration reaction is completed by NO in anaerobic zone2 -With NO3 -It is reduced to nitrogen N2.Above-mentioned four class is purified into work(
A complete ecological purification system can be formed.Cycle is continued for carbonization, ammonification, nitrification, denitrification back and forth.Return water
Facility can be that water pump adds water-supply-pipe.
The implantation methods of hydrilla verticillata are simple, can spread seed or be cut into 5~6cm black algae branch section dispersion spread to water body, in water
Any intermediary, growth and breeding can be attached in body.Required intensity of illumination is low, and light compensation point is relatively low, resistance to strong light.Optimum life
Long water temperature is 230~280C, organic matter decompose the oxygen and CO with photosynthesis release2Be conducive to the growth of black algae.Its blade and root
System can absorb N, P, K directly from water body and bed mud.
Demand of the eel grass to illumination is relatively low, and intolerant to strong light, type of seeding has：It sows seeds son, in 1.5 times that the depth of water is transparency
Under conditions of, germination percentage is up to 98%, 3 month Cheng Cong；Artificial throw is broadcast；Skewer branch etc..The root length of eel grass is about length of blade
30%, blade and root system can directly absorb N, P, K in water body and bed mud.
Growth and breeding is slow in winter with eel grass for black algae, influences clean-up effect, can plant and be suitable for winter growth breeding
Hornwort makes up.
It will produce the high aerobic layer of thin layer oxygen concentration and aerobic at the water sludge interface that black algae grows with eel grass
Bacterium can effectively completely cut off the phosphate radical PO in bed mud4 3-It is discharged to water body, makes the phosphorus content in water body will not be repeatedly.
In the thaliadeabata of aerobic zone bank plantation, well developed root system is nutrition to absorb TN, TP, COD in runoff water
Element carries out growing numerous plant.Can reach depth denitrogenate, dephosphorization and degrade COD purpose.
Above-mentioned, although the foregoing specific embodiments of the present invention is described with reference to the accompanying drawings, not protects model to the present invention
The limitation enclosed, those skilled in the art should understand that, based on the technical solutions of the present invention, those skilled in the art are not
Need to make the creative labor the various modifications or changes that can be made still within protection scope of the present invention.
