Description
Technical field
The present invention relates to pollutant abatement technology field more particularly to a kind of methods of comprehensive treatment Typical Agricultural pollution of area source
And system.
Background technique
During agricultural non-point source pollution refers to that agricultural production is lived, dissolution or solid pollutant, such as grogs in farmland, nitrogen
The organic or inorganics substances such as element, phosphorus element, pesticide heavy metal, rural area fowl and animal excrement and house refuse are being dropped from unspecific region
Under water and runoff souring, by modes such as agricultural surface runoff, agricultural drain and underground leakages, a large amount of pollutants enter river
Pollution caused by the receiving water bodies such as stream, lake, reservoir and bay.
The main forms of agricultural non-point source pollution are as follows: agricultural non -point pollution, Pollution from livestock and poultry, villager's sanitary sewage are dirty
Dye, rainwash contaminated wastewater etc..Wherein, agricultural non -point pollution includes that fertilizer amount is excessively high, fertilizer ratio is unreasonable, fertilizer stream
Lose serious and pollution of pesticide etc..Agricultural non-point source pollution has dispersibility, concealment, randomness, uncertainty, is not easy to monitor
Property and the features such as special heterogeneity, therefore, Control of Agricultural Non-point Source Pollution is difficult.
Currently, mostly using biofilter, capillary percolation, Manual moist greatly in the monitoring and control of agricultural non-point source pollution
The methods of ground or a combination of these methods technique, to achieve the purpose that control and improvement.But that there are consideration faces is narrow for the above method, stays
There is dead angle and lacks systematicness, the serious monitoring and improvement for restricting agricultural non-point source pollution.In addition, due to agricultural area source
Feature possessed by polluting, thus during control and control, control, monitoring cost low with the monitoring accuracy administered
Greatly, and difficulty of governance is much higher than point-source pollution.Further, the individual discharge of agricultural non-point source pollution is unobservable, while polluting fortune
It moves past the imperfect information of journey and is not known from the time interval for blowing down to monitoring, this more aggravates pollution sources and ambient enviroment is dirty
The difficulty of opening relationships, causes agricultural non-point source pollution that cannot obtain effective monitoring and improvement between dye level.
Summary of the invention
The present invention provides a kind of method and system of comprehensive treatment Typical Agricultural pollution of area source, can not to solve existing method
The problem of effective monitoring and improvement agricultural non-point source pollution.
To solve the above problems, the application provides a kind of method of comprehensive treatment Typical Agricultural pollution of area source, this method packet
It includes:
One, agricultural non-point source pollution source is controlled, so that primary pollutant, which forms first, administers object.Agricultural non-point source pollution source includes
Agricultural non -point pollution source, Pollution from livestock and poultry source, aquaculture pollution source, Sewage Pollution source and/or village domain
Runoff pollution source.
Two, first object progress ecological intercepting is administered, forms second and administers object.Ecological intercepting includes that retaining dam intercepts, is ecological
Chinampa intercepts, step consumption intercepts and/or biomass economy intercepts.
Three, second object progress restoration of the ecosystem is administered, forms emission.Restoration of the ecosystem includes wetland combination consumption, without hello throwing
Aquaculture and/or processing biological resource.
Following controls for specifically describing agricultural non-point source pollution source respectively, the ecological intercepting of the first improvement object and second are controlled
Manage the restoration of the ecosystem of object.
One, it for the control in agricultural non-point source pollution source, is supported in the application by control agricultural non -point pollution source, livestock and poultry
The mode for growing pollution source, aquaculture pollution source, Sewage Pollution source and/or village domain runoff pollution source realizes agriculture
Industry pollution of area source source control, so that primary pollutant, which forms first, administers object.
Specifically, following to specifically describe agricultural non -point pollution source, Pollution from livestock and poultry source, aquaculture pollution respectively
The control in source, Sewage Pollution source and/or village domain runoff pollution source.
(1) for the control in agricultural non -point pollution source
Farmland is during plant development, it will usually generate the wastes such as bag with fertilizer, pesticide bag, stalk.When rainy, fertilizer
The wastes such as bag are easy to flow into the receiving water bodies such as river with rainwash, and then pollute receiving water body.Therefore, it is necessary to
Agricultural non -point pollution source controls the wastes such as stalk.In this application, the control in agricultural non -point pollution source includes collecting to give up
