Abstract
The invention provides an ecological water draining ditch. The ecological water draining ditch comprises a cement ditch. A plurality of aquatic plant cultivating units are arranged in the cement ditch, and are filled with plant growth substrates, and emergent plants are cultivated on the plant growth substrates. By means of the ecological water draining ditch, the problems of being poor in in-farmland-drainage-water-nitrogen-phosphorus intercepting and purification capacity, low in biological diversity, poor in landscape effect and the like in an existing built cement ditch are solved, on the basis that original cement buildings and water draining are not damaged, the hydraulic retention time is prolonged, nitrogen, phosphorus and other nutrient elements in farmland drainage are intercepted, solid waste serving as aquatic plant cultivating substrates is synthetically used, a certain landscape effect can be formed according to the requirements, and the ecological water draining ditch can be applied to the non-point source pollution control field and the agricultural ecological landscape field.
Description
Technical field
The present invention relates to agricultural drain system, particularly to a kind of Demonstration for Ecological Sanitation irrigation canals and ditches.
Background technology
Pesticide, chemical fertilizer be unreasonable, and to use caused widespread pollution from the overuse of fertilizers and pesticides in rural area be the focus paid close attention in China's agricultural production, and nutrient runs off in a large number and enters rivers and lakes with rainwash, causes serious eutrophication.Agriculture drainage ditch is the important component part of irrigation and water conservancy infrastructure, can not only drain off floodwaters in time waterlogging-resistant, regulate farmland ecosystem water balance, can also pass through bed mud in gutter, plant intercepts the pollutant in the effect purification agricultural drains such as absorptions, microbial degradation, nitrogen that high efficiente callback fertilizer outflows with water and phosphorus.Environmental effect and the ecological functions of agriculture drainage ditch have been carried out substantial amounts of research by domestic and international researcher, to utilizing agriculture drainage ditch widespread pollution from the overuse of fertilizers and pesticides in rural area is intercepted and filters, and then cut down the nitrogen phosphorus entering downstream water.The domestic irrigation canals and ditches commonly used are based on tradition soil irrigation canals and ditches and cement irrigation canals and ditches at present.Tradition soil irrigation canals and ditches are domatic does not all do cure process with bottom, soil is directly exposed in water, soil erosion is easily caused time too fast meeting heavy showers or runoff velocity, and number of plant and limitednumber in tradition soil ditch, irrigation canals and ditches Water phosphorus adsorption capacity is also restricted accordingly.Cement irrigation canals and ditches have carried out cure process at the domatic cement of irrigation canals and ditches, and in the application of China farmland irrigation canals and ditches, ratio is in continuous expansion, but in cement ditch can not serike, bio-diversity is affected, therefore that the intercepting efficiency of Water phosphorus is worse.CN202610035U discloses a kind of ecological canal that can intercept nitrogen phosphorus and alleviate widespread pollution from the overuse of fertilizers and pesticides in rural area, intercepts, by planting aquatic plants, structure ecological canal, floating bed and fishing net, the nitrogen phosphorus entered in irrigation canals and ditches.CN2931467 discloses a kind of suspending type ground mass free aquatic plant purifying bed, is used for processing eutrophication water and sanitary sewage.Yang Linzhang etc. have studied ecological canal ancillary technique and intercept case, intercept current for ditch body, extend the current holdup time, and utilize the plantation of water plant to alleviate the nitrogen and phosphorus pollution entered in water body.
Summary of the invention
The purpose of the present invention, it is simply that in order to overcome the Problems existing of above-mentioned prior art, it is provided that a kind of Demonstration for Ecological Sanitation irrigation canals and ditches.
It is an object of the invention to be achieved through the following technical solutions: a kind of Demonstration for Ecological Sanitation irrigation canals and ditches, including cement irrigation canals and ditches, arrange in cement irrigation canals and ditches multiple aquatic plant cultivation unit, in each aquatic plant cultivation unit, load plant growth medium respectively, plant growth medium is cultivated emergent aquactic plant.
Described aquatic plant cultivation unit is hexagon, and six sides and bottom surface are respectively equipped with multiple hole, is connected with the cooperation in tip hole by mortise pin between adjacent aquatic plant cultivation unit.
Described plant growth medium includes haydite, zeolite and biological carbon.
Described emergent aquactic plant includes Caulis Zizaniae caduciflorae, Herba Apii, Rhizoma sagittariae sagittifoliae, Rhizoma Iridis Tectori or Canna generalis Bailey.
The plurality of aquatic plant cultivation unit is arranged in waveform along cement irrigation canals and ditches.
Above-mentioned hexagon aquatic plant cultivation unit is made up of aluminium plastic composite material or plastics, high 40-60cm, wall thickness 2.5cm, length of side 15-30cm.
Six sides of above-mentioned hexagon aquatic plant cultivation unit and the bore dia of bottom surface are about 1cm, aquatic plant cultivation unit can be divided into for two types, one topmost arranges tip hole six sides, tip bore dia 3cm, another kind topmost arranges mortise pin six sides, mortise pin diameter 3cm, long 2cm, be connected with the cooperation in tip hole by mortise pin between adjacent aquatic plant cultivation unit.
Above-mentioned plant growth medium is based on diameter in the pottery gravel of more than 1cm, zeolite and biological carbon, and substrate itself has nutrient substance absorption and interception function.
The water plant cultivating Seedling is placed in unit, puts in canal when irrigation canals and ditches start draining by cultivation unit after inserting cultivation unit by substrate, after rice harves, water plant is gathered and the cylinder of cleaning cultivation simultaneously, effectively preventing and treating plant secondary pollution.
Above-mentioned hexagon aquatic plant cultivation unit can also be arranged as S shape, tufted or 60 ° arranged in parallel, can reach remove nitrogen and phosphorus pollution purpose, also can reach the landscape effect of farmland ecosystem.
The present invention is according to ecological principle, under the premise considering the factors such as hydrologic condition, weather conditions, irrigation canals and ditches geometric properties, irrigation canals and ditches drainage load and holdup time, develop a kind of water plant can being placed in cement irrigation canals and ditches and cultivate unit, for transforming cement irrigation canals and ditches as ecological canal, this method is flexible and changeable, not only having the effect controlling rice field pollution of area source, multipath combined method also is able to bring new view for rice field and irrigation canals and ditches.
