Abstract
The utility model discloses an ecological interception channel for farmlands. The cross section of the ecological interception channel for the farmlands is a trapezium; hardened sheet materials of honeycomb shape concrete are used on two walls and the bottom of the ecological interception channel for the farmlands; a plurality of filter boxes are arranged separately on the bottom of the end of the channel in shape of snake; the filter box is a box body with bores distributed throughout on four walls and adsorbing materials filled inside; regulating sluices are arranged on the separated segments of the channel; two water control valves are arranged on the positions near the middle part of the regulating sluice. Plants which have higher abilities of absorbing nutrient elements N and P are planted in the honeycomb shape bores for absorbing the nutrient elements N and P in the farmland drainage. With the reasonable structure design, the utility model can intercept the nutrient elements N and P in the farmland drainage to reduce the eutrophication of the receiving water, and the ecological interception channel for the farmlands has good popularization value in the non-point source pollution control in the agriculture.
Description
Technical field
The utility model belongs to the farmland drainage system, relates to a kind of agricultural channel, particularly relates to a kind of agricultural ecological interception channel, is used to control agricultural non-point pollution.
Background technology
Body eutrophication is the ubiquitous environmental issues in countries in the world, and China is no exception, and along with the Chinese society rapid economy development, body eutrophication presents general and serious day by day developing state.Cause the source of pollution of body eutrophication can be divided into point-source pollution and non-point pollution, wherein, non-point pollution accounts for 2/3rds of gross contamination amount, and rural activity to the contribution rate of non-point pollution up to 75%.Therefore, effectively control farmland N, P nutritive element just become control Researches on Agricultural Non-Point aspect to the pollution of receiving water body important content.
Prevent and treat the achievement in research of aspect according to agricultural non-point pollution both at home and abroad at present, biology-ecological reestablishment is acknowledged as the logical pollution treatment thinking of harmonious co-existence between man and nature and the technological line of innovation, and has treatment effect and reach the low advantage of construction costs and running cost well.And in many technical measures of applying biological-ecological reestablishment control agricultural non-point pollution, most characteristic, the most fruitful ecological engineering measure surely belongs to buffer strip, comprises three types of buffering wetland, buffering forest belt and buffering lawn belts etc.But, therefore be difficult to China's application of having a large population and a few land because the measure of buffer strip ecological engineering need take bigger land area.
In China, farmland ubiquity irrigation and drainage channels system is broadly divided into two types according to the different farmland discharging-irrigating canalizations of construction material: soil property channel and concrete canal.The subject matter that the soil property channel exists is to be easy to generate soil erosion and the weeds that grow thickly, and the both produces receiving water body and pollutes.The subject matter one that concrete canal exists is that water speed is very fast, is difficult to the silt in the sedimentation draining more fully; The 2nd, lack plant and microorganism, the N in the draining that can not absorb, adsorbs and degrade, P nutritive element.
Summary of the invention
The purpose of this utility model is to provide a kind of agricultural ecological interception channel, and it mainly is at the agricultural non-point pollution problem.Utilize agricultural ecological interception channel provided by the invention, can not only effectively tackle N, P nutritive element in the farmland drainage, simultaneously can make full use of original farm field irrigation drainage channel, solved the problem that ecological engineering takies more arable land.The present invention has construction costs and maintenance cost is low, Operation and Maintenance is simple, pollution control is effective, be convenient to characteristics such as large scale application.
Above-mentioned purpose of the present utility model is achieved in that a kind of agricultural ecological interception channel, the transverse section of this channel is trapezoidal, it is characterized in that, concrete with honeycombed spots sheet material hardization is adopted in two walls of channel and bottom, be disposed with some strumboxes in the bottom of channel, described strumbox, be a wall be covered with the hole, in fill the casing of sorbing material.
This agricultural ecological interception channel is to carry out certain biotechnology transformation to form on original farmland drainage channel basis.Not only had solid native Bao Di effect but also had by plantation in the hole of the concrete with honeycombed spots sheet material of channel two walls is perennial N, the P nutritive element economic plants of receptivity by force; And in the hole of the concrete with honeycombed spots sheet material of channel bottom plantation to N, P have strong receptivity very water, swim and heavy water type economic plants, adsorb, absorb and the draining of degrading in N, P nutritive element.
Above-mentioned these plants can not only absorb N, P nutritive element, reduction water speed, the sedimentation silt in the draining, and can also produce economic benefit.
Agricultural ecological interception channel described in the utility model is characterized in that, described strumbox preferably is the bottom that snakelike shape is arranged in the channel end each other with interval.
By channel terminal separated by a distance and become snakelike placement some amount, in fill the strumbox of sorbing material, the plantation of strumbox top has the plant of strong receptivity to N, P nutritive element, because barrier effect, the adsorption of sorbing material, the sorption of plant and the Degradation of microorganism of strumbox, therefore can not only reduce water speed, sedimentation silt greatly, and the N in the draining of further adsorbing, absorb and degrade, P nutritive element.
Agricultural ecological interception channel described in the utility model is characterized in that, can segmentation be provided with regulating sluice in channel.
By the throttling action of regulating sluice, increase the residence time of draining in channel, make sedimentation, absorption, absorption and Degradation more complete.
Agricultural ecological interception channel described in the utility model is characterized in that, the nearly medium position of described regulating sluice preferably is provided with two water control valves.Described two water control valves can be arranged on same level attitude by left and right symmetrically.
Below in conjunction with specific embodiment and accompanying drawing thereof agricultural ecological interception channel system is described further.
