Description
Technical field
This technology invention is related to the innovation of the important technology in heavy metal pollution of soil improvement field, is agricultural production
Complex art application.Breeding technology is integrated by scientific utilization agricultural production, reaches and solves paddy soil heavy metal pollution
The effect of restoration of the ecosystem is administered, while solving that the heavy metal pollution repairing and treating that faces at present is of high cost, attend to one thing and lose sight of another, can not
A series of problems, such as lasting, pattern difficulty popularization, land restoration output, be a major transformation of Heavy Metal Pollution Control method,
It is also the breakthrough of CERCLA directed thinking.
Background technology
The heavy metal pollution of soil used at present, which administers repairing method, to be had very much, and wherein physical restoration has heavy metal pollution of soil, soil removal and replacement
Method and deep plowing method, electric heating repairing method, vitrification, Electroremediation etc.；Chemical restoration has chemical fixation, soil
Elution, phytoremediation (including plant stability or solidification, plant absorption, phytovolatilization, plant degradation) etc., although all carrying out
A degree of research, test effect also have, but can not be promoted because of some somewhat expensives, some be limitation it is too strong and
Popularization face is limited, some, which are laboratory's effect and pilot scale gap, can not promote greatly very much.Just at present in the depth of popularity application
Although turn over, lie fallow, optimize moisture management and control, soil conditioner, straw remove the methods of have certain effect, each method
The result of single use is controlled since peasant household can't see the income that the soil same period brings because administering the use of restorative procedure in reparation
It gives a discount during reason and due effect is not achieved.
Cultivated, heavy metal pollution of soil and soil replacement method are ploughed deeply, these engineering measures are that the classical heavy metal pollution of soil improvement of comparison is arranged
Apply, have the advantages that thoroughly, stablize, but implement that quantities is big, and investment cost is high, destroy soil structures, cause under soil fertility
Drop, and also the dirty soil to swap out is stacked or handled, therefore be not a kind of ideal contaminated soil remediation method；Change
It is that chemical reagent or chemical material are added in the soil to learn fixation, is formed insoluble between heavy metal using them or moved
Dynamic property is poor, small toxicity substance and reduce its biological effectiveness in the soil, reduce it to water body and plant and other environment
The chemical remediation of contaminated soil is realized in the migration of unit, and the key of this method is successfully to select a kind of economy effectively solid
Up to the present agent has a large amount of improved materials and is applied, most widely used is exactly lime or calcium carbonate, can play and carry
High P in soil H values form the chemical combination such as phosphoric acid, light rock phosphate in powder, triple superphosphate, the silicate of slightly solubility precipitation with heavy metal element
Object, the organic matters such as mineral, the humic acid such as the high sepiolite of Cation adsorption amount, palygorskite, zeolite, montmorillonite and some to people
Body it is harmless or beneficial to and have the metallic element of antagonism to heavy metal.Chemical fixation is simple and practicable, but be not it is a kind of forever
Long reclamation activities, because it only changes heavy metal, existing form, metallic element remain in soil in the soil,
Easy reactivation endangers plant, in addition, the use of modifying agent will change soil texture to a certain extent, while to soil
Microorganism may also generate certain influence；Phytoremediation be using plant extract, absorption, decomposition, conversion or fixing soil,
The general name of hazardous contaminant technology in deposit, sludge or earth's surface, underground water, by certain specific planting in weight
On the soil of metallic pollution, this kind of plant has special absorption accumulation ability to the pollution element in soil, simultaneously by plant harvest
The heavy metal species soil body be can be removed after dealing carefully with, pollution control and restoration of the ecosystem achieved the purpose that.Because its in situ into
Row processing, of low cost, effect is permanent and has taken into account aesthetic effect and has obtained being widely recognized as the public and academia rapidly,
If but large area is promoted in rice field and also brings along grain security hidden danger.
Due to the complexity of soil texture and the otherness of type, the soil of heavy metal pollution often has an a variety of huge sum of moneys
Belong to, and also with the otherwise pollution such as organic matter.A variety of methods are needed to be applied in combination in repair process, therefore should
Improve it is corresponding repair system, single methods for curing heavy metal contamination in soil is often all due to of high cost, unsustainable, very
It can not implement to attending to one thing and lose sight of another.
The material that carries weight shows that the whole nation is up to 12,000,000 tons by the grain of heavy metal pollution every year, and direct economic loss is super
Cross 20,000,000,000 yuan.
Nanjing soil research institute of Chinese Academy of Sciences researcher, doctoral advisor's heavy metal pollution of soil are repaired expert Zhou Jing and were once referred to
Go out：During heavy metal pollution of soil repairing and treating, (contain as reduced rice cadmium reducing heavy metal-polluted soil biologically effective activity
Amount), subtract and deposit heavy metal-polluted soil total amount etc. and obtain certain effect.But need further to be solved there is also many problems.
For example, how to maintain lasting repairing effectImprove the output of land restorationReduce the cost repairedThe duplication of reparation pattern
It promotesImprove the ability etc. of public participation.
Invention content
It is to create against the above deficiency to invent rice field synthesis breeding technology ecology repairing heavy metal in soil method for governing pollution
The persistence of new a kind of not only certifiable repairing effect, but also the output of land restoration is improved, it also reduces rehabilitation cost, repair
Complex pattern not only reproducible popularization but also had improved the dynamics of participation of the public, the ecological remediation and treatment method achieved many things at one stroke.
The embodiment for realizing this technology subject invention：
By the appropriate reconstruction to rice field adaptation to local conditions, rice field synthesis breeding binding pattern is taken to form the rice having complementary advantages
Field ecology stove, restoration of the ecosystem paddy soil heavy metal pollution of area source improve agricultural product quality and comprehensive benefit, in paddy field cultivation
Suitably match on the basis of rice and supports some suitable foster kinds (such as fish, shrimp, the frog, loach, eel, tortoise, soft-shelled turtle, crab, duck, river snail), fully profit
(such as with the natural biology bait in rice field：Water plant, planktonic organism, humus etc.), reach and not only ensure grain yield, but also increases
Rice field income, has also carried out heavy metal-polluted soil controlling area-source pollution, and rice field ecology synthesis breeding is that really steady grain increases
Effect, the industry of environmental pollution improvement's ecological benefits two-win.
1, it ploughs deeply cultivated：The Kai Yugou (deep 60cm or more) of breeding is integrated in conjunction with rice field, fish cheats (100cm or more) to the rice that ploughs
Field arable layer plough deeply cultivated (20cm or more)-and effectively reduces arable layer heavy metal contaminants content, improves paddy soil farming
Layer thickness and structure promote farmland quality.Special rice field has been met or exceeded when carrying out rice field fishing ditch fish hole and breeding farming
Heavy metal pollution of soil repairing and treating " ploughing deeply cultivated (15-20cm) " has saved a large amount of paddy soil weights while requirement with effect
Metallic pollution repairing and treating " ploughs deeply cultivated " specific project expenditure；
2, using quick lime：In conjunction with rice field synthesis breeding preceding rice field disinfection leave nothing usable to the invading enemy using quick lime (100 kgs/acre with
On)-adjusting heavy metal element in P in soil H values, curing soil, it is active and reaches improvement heavy metal pollution of soil and repaiies to reduce
Multiple regulation effect cannot be perfunctory to since it is that disinfection is left nothing usable to the invading enemy using purpose, so used using rice field comprehensive ecological breeding
The regulation effect that " quick lime " reaches also as save heavy metal pollution of soil and administers " quick lime " special expense while more preferable；
3, optimize water management：Rice field synthesis breeding water in field position must assure that the living space of breed variety, water level remove
10cm depths or more are maintained at outside dry field for a long time, has effectively completely cut off the contact of Tian Tuyu air for a long time, has reached heavy metal-polluted soil
Pollution control soil moisture control management reduces the actual effect of heavy metal pollution of soil, due to keeping paddy field aquaculture water level to be
Production process is necessary, so having saved the spending of special administration funds；
4, biological regulator：It is to be reacted heavy metal element oxygen etc. by the physiochemistry of microorganism and heavy metal element
Change, Reduced separating reduce its toxicity, achieve the purpose that pollution administration.Rice field ecology applies fermentation during integrating breeding
Organic fertilizer increases organic matter in paddy soil, the excrement of aquaculture product is all good geobiont conditioning agent, Er Qieyou
Sludge, the characteristic that burrows in breed variety, uniformly improve plough horizon, are adjusted than artificial and mechanical application soil
Evenly, soil regulating effect is more preferable for agent.
5, plant removes：Using the principle of plant absorption absorption the Cheng Ji plant roots of plurality of heavy metal element, stem, leaf
(straw etc.) removes.Rice field ecology synthesis breeding can more thoroughly accomplish that effect is certainly also more preferable as production link.
Paddy soil Heavy Metal Pollution Control restorative procedure unit cost used at present is high, and effect is undesirable.Rice field is comprehensive
It closes breeding technology and integrates heavy metal pollution of soil improvement ecological restoring method, effect of integrated pest management is administered better than each individual event
The sum of.It is exactly that heavy metal pollution of soil administers restoration of the ecosystem work, and its effect is more preferable to promote rice field synthesis breeding technology, together
When need not in addition to rice field input heavy metal pollution of soil administer repair specific project expenditure.
