A kind of domain, and in particular to field original position ecological circulation water process irrigation and drainage system with functions.
Background technique
Heavy metal pollution of soil, water eutrophication and organic contamination are more serious in China's agricultural production.Some areas
Even without the good soil that can be used to produce crops.For these environmental problems, domestic and international expert utilizes multiple means
It is studied, and gradually implements effective achievement, achieve certain effect." 4R " skill such as proposed for agricultural non -point pollution
Art achieves good renovating effect in the agricultural non-point source pollution region use of large area.And it is just extensive throughout the country
Carry out promote.Since the technology uses ecological means, the regulation time is longer, and for pollution level, seriously regional effect is simultaneously
It cannot realize quickly.Other place also starts with plant engineering, microorganism is prevented and treated, and has certain effect.Tradition
Although soil moved in improve the original soil removal and replacement can largely solve contaminated soil, in the utilizable free of contamination soil resource in China
It is not appropriate in the case where fewer and fewer.There are also the means such as eluted, distilled to heavy-metal contaminated soil also to want high expense
With.Water and soil pollution in situ is administered also in numerous studies, such as utilizes some modifying agents, special fertilizer, microorganism, but it is each
Kind means regulation effect is different, has been difficult to effective simple and easy method especially for soil type, geographical location and has solved.So
And most measures do not account for carrying out local contaminated underground water improvement utilization yet, cause the recurrence of Final pollution phenomenon.
Underground water pollution is detected and is administered very urgent.

It is irrigated in process of crop growth, lower infiltration enters physical subsurface purifying area, prevents nutrient loss.Underground water
Position also passes through physical subsurface purifying area when rising, the absorptions such as biomass carbon, haydite stop the accumulation of salinity, while retention
Nutrient be supplied to crop as needed, cannot mistake so need to carry out plant growth nutrient management according to the local situation
More applications, the case where upper one batch of crop nutrition content is trapped can be considered in next process of crop growth, carries out weight-reducing application.
Moisture is flowed into IIth area of Ith area of ecological intercepting ecological intercepting and ecological intercepting in infitration process, passes through plant and life
The further absorption cleaning of object film, is flowed into IIIth area of ecological intercepting, and pollutant in water or nutrient more than needed pass through phytoplankton
And the further absorption of the microorganism generated around zeolite, goose soft rock.The region can reduce water velocity simultaneously, extend
The absorption cleaning time slowly enters biomembrane-haydite purifying area and is further purified, and eventually enters into cleaning water source memory block, can
It is irrigated with recycling and reusing, realizes that regional water processing cycle utilizes.
Above-mentioned all biomembranes used and plant, which can shift to an earlier date, carries out culture of the week from biology, plant in cultivation region
Nursery etc., advantageously reduces cost, facilitates the water process in construction and later period.
The present invention has certain effect to pollution of area source, heavy metal pollution, the You machine object Wu Ran Alto in agricultural production.Especially
It is counterweight Polluted area, can tentatively realize purification after a year, and second year can start to produce the agriculture of green non-pollution
Product.The present invention can obtain various economic values simultaneously, reduce cost, realize certain economic well-being of workers and staff.
The present invention provides the thinking and method of a kind of field original position ecological circulation water process irrigation and drainage system with functions, specific implementation should
There are many method and approach of technical solution, the above is only a preferred embodiment of the present invention, it is noted that for this technology
