Abstract
The invention belongs to ecological condition project and hydraulic engineering technology field. It is based on indigene species, keeps the principle of 'from nature, excelled nature' to carry on ecology design, the designed groove, canal, river, bank, constructed swamped land, waste water processing system, and has merits of waste water process, greening and bank protection, beatifying landscape and continuous resources. Through constructing nature simulating ecological system, it can display the waste eliminating function of constructed swamped land system fully, but also it can upgrades material producing ability, and the cost is low, easy to be operated, the area is small.
Description
One, technical field:
The invention belongs to ecological environmental protection engineering and hydraulic engineering technical field.
Two, background technology
At present, adopt three kinds of methods both at home and abroad during rural area and cities and towns effluent sewage pollution of area source are handled: surface stream wet land treating method, current wetland processing method and vertical-flow wetland processing method.
1. wet land treating method is flowed on the surface
Directly soil surface plantation hygrophyte, effluent sewage flows at soil surface.By the flow-control of intake-outlet, regulate surperficial water level and effluent sewage holdup time in internal system.Infilter under the moisture into the plant rhizosphere district, by microorganism and animal activity and plant absorbing, conversion and the memory function in rhizosphere district, degraded and purification effluent sewage.Although this processing method cost is low, its purification efficiency is low, and needs large-area soil, is difficult to promote in China that area is very low per capita.
2. current wetland processing method
Soil is transformed, and layering inserts absorption and converting materials such as gravel, the grains of sand, lays the ventilating water pipe network, mulching soil, and plantation hygrophyte.Flow in the ventilating water pipe of effluent sewage below soil.By the flow-control of intake-outlet, regulate undercurrent water level and effluent sewage holdup time in internal system.By microorganism and animal activity and plant absorbing, conversion and the memory function in rhizosphere district, degraded and purification effluent sewage.Although this processing method purification efficiency height, its cost is also high, and needs large-area soil, is difficult to carry out in area China very low and underdeveloped per capita.
3. vertical-flow wetland processing method
Select the higher massif of relative fall, domatic along it, soil to be transformed, layering inserts absorption and converting materials such as gravel, the grains of sand, lays the ventilating water pipe network, mulching soil, and plantation hygrophyte.Effluent sewage flows in pipeline naturally to the foot of the hill from the hilltop.By the flow-control of intake-outlet, regulate undercurrent water level and effluent sewage holdup time in internal system.By microorganism and animal activity and plant absorbing, conversion and the memory function in rhizosphere district, degraded and purification effluent sewage.Although this processing method purification efficiency height, its cost is also high, and needs the higher landform of drop, and its enforcement and popularization have limitation.
Because irrigation canals and ditches river sloping bank SEA LEVEL VARIATION is big, alternation of wetting and drying is violent and water drop is little, irrigation canals and ditches river sloping bank can not satisfy the requirement that above-mentioned three kinds of wet land treating methods are built.Simultaneously, above-mentioned three kinds of wet land treating methods are built in the water catchment area in irrigation canals and ditches river usually, all take large-area soil.
Three, summary of the invention
The objective of the invention is to based on endemic species, the expense of setting up is cheap, easy operating, be convenient to management, save time and obvious results irrigation canals and ditches river sloping bank constitution wetland effluent sewage processing method the effect that play and handle effluent sewage, counterfort virescence, beautifies view and resources.And, be based upon area, the irrigation canals and ditches network of waterways and be easy to the method promoting and adopt according to the requirement of complex technology easy, high-tech technical applicationization and supporting technology through engineering approaches.
Technical scheme of the present invention is partly formed by making up compound riverbed, construction sloping bank undercurrent filtration system, construction sloping bank surface low system, construction embankment vegetation and four of aquatic vegetation systems.Specifically comprise:
1. make up compound riverbed: by engineering measures such as widening, scabble, deep-cut, cashing the riverbed is compound riverbed, comprises inlet channel, diversion traverse furrow, interception band, is detained sedimentation basin and coarse filtration grid (Fig. 1) thereof.
2. build sloping bank undercurrent filtration system:, adopt the honeycombed cement plate that the interception band is set in both sides, compound riverbed; Between interception band and diversion traverse furrow, utilize the filter bed framework and the diafiltration dam framework of honeycombed cement plate structure multilayer, add in the framework and fill the composite interstitial substance of forming by gravel, flyash and peat, filter bed and surface, diafiltration dam plantation humidogene and emergent aquactic plant; In the side of diafiltration dam facing, lay the renewable filter bed of forming by porous elastic material to the diversion traverse furrow.Form complete sloping bank wetland undercurrent filtration system (Fig. 2).
3. build sloping bank surface low system:, adopt the honeycombed cement plate that the interception band is set in both sides, compound riverbed; Soil surface between interception band and diversion traverse furrow is directly planted humidogene and emergent aquactic plant, forms sloping bank surface stream wet land system (Fig. 3).This system and domatic undercurrent filtration system be in the riverbed (Fig. 1) alternately.
4. make up embankment vegetation and aquatic vegetation system: at the top, riverbank, directly plant arbor, shrub and turfgrass, form embankment view vegetation; Plant multiple submerged plant in the following riverbed of the main stem water surface, form river aquatic vegetation system.
The present invention is raw material with the endemic species, adheres to that the principle of " come from nature, be better than nature " is carried out the ecology design, can not constitute a threat to the indigenous ecosystem.By making up imitative natural ecosystems, can not only give full play to the dirt-removing functions of wet land system, improve system's physical capacity, and with low cost, easy operating, floor space are little.The pollution of area source of China administer and the restoration of the ecosystem of the irrigation canals and ditches network of waterways in have broad application prospects.
