Preferably, described ecological pond is based on planting aquatic plants, cultivates and has algae and zooplankton, throws in the biological pond having fish, spiral shell and freshwater mussel.
The beneficial effects of the utility model: combine with the biological oxidation pool (being called for short " ecological pond ") owing to adopting anaerobism-foster-aerobic multi-stage biological filter tank of holding concurrently, and the volcanic rock biological filter material that specific surface area is larger can be adopted to be filler, water level elevation is arranged from high to low, solve microorganism rapid biofilm, the problems such as water body unrestricted flow and purification of water quality efficiency, because the water inlet of landscape artificial lake is mainly derived from reservoir filling, sewage disposal plant effluent, polluted river etc., purify into Lake Water Body through the utility model, the water quality requirement of landscape water can be reached, effectively prevent and treat landscape lake generation eutrophication.
Accompanying drawing explanation
Fig. 1 is plan structure schematic diagram of the present utility model;
Fig. 2 is cross-sectional view of the present utility model.
Embodiment
See Fig. 1 and Fig. 2, the utility model provides a kind of multi-stage biological filter tank-ecological pond purification system be applicable to into lake landscape water body, connect ingoing river/artificial canal and man-made lake 5, purified from ingoing river/artificial canal by the anaerobic filter 1 of connecting successively, multi-stage biological processing units such as supporting filter tank 2, aerobic filter tank 3 and ecological pond 4 of holding concurrently, make it meet to enter the requirement of man-made lake, this system itself also can be viewed and admired for people and play as a part for view simultaneously.
Here is illustrating this system components.
Between adjacent filter tank and all successively superpose the trapezoidal divider wall 6 of formation between filter tank with ecological pond with lattice guest gabion 61, lattice guest gabion inside adopts particle diameter 10-20cm cobble to fill.For meeting the hydrophilic demand of citizen, divider wall arranges water balcony function, and divider wall top is that 50cm is wide, and evenly lays 30cm X 20cm rectangle concrete brickmaking 62, for people's walking.
Anaerobic filter, hold concurrently and support filter tank, aerobic filter tank, ecological pond by the design in filter tank different depths and different filtrate footpath, realize its respective water quality purification function, anaerobic filter, the filtrate of supporting filter tank and aerobic filter tank of holding concurrently are volcanic rock biological filter material 7, volcanic rock biological filter material is natural cellular porous material, comparatively large without sharp shape, surface irregularity, specific surface area, porosity is larger, easy formation microorganism colonization, not easily results in blockage.
The degree of depth of anaerobic filter, foster filter tank of holding concurrently, aerobic filter tank, ecological pond is followed successively by 2-2.5 m, 1-1.2 m, 0.5-0.6 m, 0.4-0.6 m, it is 10-20cm that divider wall elevation and the design of upper level filter tank fill filtrate difference of elevation, while ensureing the upper level filter tank depth of water and the water yield of regulating and storing, water body falls by divider wall space and top and enters next stage filter tank by upper level filter tank, water body is aeration oxygen enrichment in falling process, increases the content of dissolved oxygen in water body.
Every grade of filtrate in anaerobic filter, oxygen filter tank of holding concurrently, aerobic filter tank is filled and is formed that both sides volcanic rock biological filter material particle diameter is large, hole is large, middle volcanic rock biological filter material particle diameter is little, hole is little, volcanic rock biological filter material particle diameter increases step by step with filter bed level time: wherein volcanic rock biological filter material particle diameter in anaerobic filter both sides is 10-15 mm, middle volcanic rock biological filter material particle diameter 4-10 mm; Both sides, oxygen filter tank volcanic rock biological filter material particle diameter of holding concurrently is 30-50 mm, middle volcanic rock biological filter material particle diameter 10-15 mm; Both sides, aerobic filter tank volcanic rock biological filter material particle diameter is 50-60 mm, middle volcanic rock biological filter material particle diameter 30-50 mm.
Last step biological processing unit is ecological pond, based on planting aquatic plants 41, cultivates algae, zooplankton, throws in fish 42, spiral shell, freshwater mussel etc., build the ecosystem be made up of the producer, human consumer, decomposer, purify water.North China waterplant is strong anti-pollution Herba Eichhorniae, middle anti-pollution reed, calamus, wilson iris, few pollution submerged plant hornwort, eel grass, p.malaianus etc.
Sewage work/reuse water plant effluent and to enter suspended particulate content in Lake Water Body water by the river etc. of Sewage Pollution higher, after entering native system, retaining by filter tank, filter, precipitation, the physics such as decomposition, chemistry, biological action effectively reduces suspended particulate content, water body is through anaerobism-foster-aerobic processes of holding concurrently, in water body, organism can be fermented the decomposition such as bacterium, nitrogen is removed water body by anoxic denitrification effect and aerobic nitrification effect, phosphorus is through anaerobism, aerobicly to be decomposed under polyP bacteria effect, absorb, , absorbed by waterplant in the ecosystem at ecological pond of the water body of multi-stage biological filter tank rough purification, food chain accumulation and microbial decomposition, realize the deep purifying of water quality.
Each optimization technique means disclosed in the utility model, unless otherwise indicated and optimization technique means be outside the further restriction of another technique means, all can arbitrary combination, form some different technical schemes.
