Abstract
The invention relates to a sector-shaped multi-dimensional cross-flow type composite terrestrial plant buffer zone and a construction method thereof. The buffer zone is formed by connecting a sector-shaped transverse-flow herb-biochar zone, a sector-shaped longitudinal-flow denitrification zone, a sector-shaped transverse-circular-flow pollutant enrichment shrub-herb zone, a sector-shaped longitudinal-flow dephosphorization zone, a sector-shaped transverse-circular-flow tree-herb-biochar zone as well as necessary ridges, braiding channels or water-permeable walls in series. Low-concentration wastewater such as tail water of urban sewage treatment plants, agricultural wastewater, surface runoff of villages and small towns and the like sequentially flows through the zones after simple sedimentation, and suspended matters, organic matters, nutrient elements, pesticides and the like in the wastewater are gradually reduced. The vegetation buffer zone is applicable to peripheries of reservoirs, rivers or lakes with limited shore land areas and can effectively prevent water environment pollution; native plants are combined harmoniously, so that the buffer zone has the good treatment effect as well as the good landscape effect, the good ecological benefit and high popularization and application values.
Description
Technical field
The invention belongs to water pollution control and ecological restoration technical field, be specifically related to a kind of fan-shaped multidimensional cross-current type compound terrestrial plant buffer strip and construction process thereof.
Background technology
Land inland water ecotone, as a kind of ecological engineering unit protecting water body, can be tackled the suspended substance in waters such as entering lake, reservoir, river, remove nitrogen and phosphorus element, degrading pesticide, ensure the quality of water surrounding.Simultaneously; land inland water ecotone is also the important component part of region nutrient management, soil erosion control and scheduling co-design Freshwater resources environment; it plays the effect of important gallery, strainer and barrier to the material cycle between the ecosystem of land and water, flow of energy, information transmission and biological stream, plays a part very important to the steady progression of local ecosystem.But along with the aggravation of water body extraneous contamination degree, single land inland water ecotone has been difficult to this pollution exceeding its processing load of reply.How to use a kind of novel method to solve this kind of problem, become the trend of vegetation buffer strip development.
Publication number is that the Chinese patent application of CN101555071B discloses a kind of buffer strip that utilizes and controls the method for agricultural non-point source pollution of tidal river network area of plain, and patent application mainly comprises: select buffer strip areas, buffer strip edit, arrange buffer strip water distribution system, buffer strip plant chooses and to plant and buffer strip water source imports.The patent describe a kind of method utilizing ecological engineering principle to remove Riparian Zone widespread pollution from the overuse of fertilizers and pesticides in rural area, be applicable to river network in plain areas, but due to the impact by areal type and water body type, so use the limitation of the method larger.
Publication number is a kind of method that the Chinese patent application of CN102249416A discloses loke shore buffer strip ecological reconstruction, totally be divided into 5 steps, that is: draw the line, remove and transform substrate, arrange collect ditch and water distribution ditch, ecological permeable purification zone is set, determine build technique.The method fundamentally describes the macro-plan method building loke shore buffer strip, also highlights the thought taking into account ecological protection while protection loke shore environment simultaneously.But also there is following defect: plant that patent uses mainly waterplant and kind is single; Do not design the current polluting water, system function subregion is indefinite, interception result and scarce capacity.
In addition, there is following problem in foregoing invention and correlative study:
