Embodiment
Be below specific embodiments of the invention, technical scheme of the present invention is described further, but protection scope of the present invention is not limited to these embodiments.Every do not deviate from the present invention's design change or equivalent substituting include within protection scope of the present invention.
As shown in Figure 1, a kind of ecological treatment apparatus of reuse water supply landscape water, complete assembly locates below ground level, comprise pretreatment pool 7, anaerobe pond 10, Artificial subsurface flow wetland 18, biological filter 27 and landscape pond 29, described pretreatment pool 7 is near residential quarters building water exhaust system, described anaerobe pond 10 connects pretreatment pool 7, overflow weir 8 is provided with between anaerobe pond 10 and pretreatment pool 7, overflow weir 8 is provided with overflow weir 9, the anaerobic pond water outlet 11 in described anaerobe pond 10 and the wetland of Artificial subsurface flow wetland 18 are intake and 12 to be connected, described Artificial subsurface flow wetland 18 is arranged on around the building of residential quarters, the wetland effluent 23 of described Artificial subsurface flow wetland 18 and the biological filter of biological filter 27 intake and 24 to be connected, under described biological filter 27 is arranged on road surface, residential quarters, the biological filter water outlet 25 of described biological filter 27 is connected with landscape pond 29, described landscape pond 29 is arranged on residential quarters central authorities or low-lying place.
Particularly, described pretreatment pool 7 top is provided with wastewater influent 1, hand basket fine fack 2 and support bucket 4 is provided with in pretreatment pool 7, hand basket fine fack 2 hangs on support bucket 4, described support bucket 4 is supported by bucket edge and support point 6, the base plate of described support bucket 4 is the poroid supporting plate 5 of live-in with bayonet, supporting plate 5 posts filter membrane 3.
Particularly, described wetland water inlet 12 is connected through equalizing tank 13 one end with Artificial subsurface flow wetland 18, and the other end of described Artificial subsurface flow wetland 18 is connected with wetland effluent 23 through water collecting basin 22.
Particularly, described Artificial subsurface flow wetland 18 is one group or several groups of strip flower ponds, inwall does WATER REPELLENT, two ends ecto-entad fills cobble 14 and vermiculite 15 filter material layer, the underfill of described Artificial subsurface flow wetland 18 has matrix, Medium Culture kind is implanted with wetland plant 19, and described matrix is followed successively by turfy soil 16, canebreak 20, haydite 21 from the bottom to top.
Particularly, described Medium Culture is vertically provided with multiple flap 17, and wetland plant 19 kinds is planted between flap 17.
During operation, wastewater influent 1 is filtered through hand basket fine fack 2 and filter membrane 3 and is entered pretreatment pool 7, sewage filters through filter membrane 3, the organic pollutant of more than 30% can be removed, suspended substance in sewage, solid particulate and part macromole zoogloea be not by filter membrane 3, effectively alleviate the silting of wetland 18, also greatly reduce the degraded load in anaerobe pond 10.
Filtered water enters anaerobe pond 10 through overflow weir 8, and in pond, temperature is comparatively constant, is not vulnerable to extraneous air, temperature fluctuations affect, for anaerobic bacterium, amphimicrobe and Ammonifying bacteria provide good breeding place.In anaerobe pond 10, sewage is carried out sufficient anaerobic hydrolysis-acidification, wherein the organism of polymer difficult degradation all can change the organism that low molecule is easily degraded substantially into, improves the ratio of BOD/COD in sewage, is conducive to absorption and the degraded of wetland plant 19.
Anaerobe pond water outlet 11 enters Artificial subsurface flow wetland 18 through equalizing tank 13, different matrix, is of value to the existence of different types of microorganisms, and vermiculite 15 and haydite 21 also effectively can alleviate the silting of wetland 18.Wherein turfy soil 16 layers did not have plant fibrous root, therebetween canebreak 20 thin layer, and top covers haydite 21 layers.Wetland plant 19th floors front or area without shade plantation flag flowers, roadside or shady spot's plantation cyperus alternifolius.Evergreen aquatic iris cold hardiness is strong, and metabolism is vigorous, even if in the winter time, also can play effect in absorption water pollutant; And sewage plantation cyperus alternifolius wetland in stop 10d after, in sewage, TN, TP, COD, BOD clearance can reach 70 ~ 90%.Wetland plant 19 is except directly absorbing pollutent, also has important indirect action: oxygen is transported to plant root from top, thus form an aerobic environment at plant root, increase gradually along with from root system distance, anoxic, anaerobic state is there is successively in wetland, such conditions favouring in the growth of nitrifier and denitrifying bacteria, and then strengthens the effect of wetland microorganism nitrification and denitrification, improves the purification efficiency of N in sewage.Artificial subsurface flow wetland 18 couples of P also have good removal effect, depend primarily on plant absorption, the adsorption filtration of matrix and the acting in conjunction of microbial transformation three.Microorganism in Artificial subsurface flow wetland 18 can also eliminate the peculiar smell of sewage.Artificial subsurface flow wetland 18 operational mode is designed to vertical baffling wetland, namely flap 17 is added in wetland inside, make current flow process elongated, fluidised form is more even, thus raising hydraulic detention time, increase pollutent with filler, root system of plant and biomembranous duration of contact in wetland, make physics, chemistry and the biological respinse removed needed for pollutent carry out more abundant, the more common wetland of pollutants removal rate significantly improves.Wetland moisturizing can take the mode of intermittent moisturizing according to practical situation.Above Artificial subsurface flow wetland 18, summer arranges Chinese wistaria frame 31 for sun-proof, and effect as shown in Figure 3; Winter, frame covered closed transparent plastic greenhouse 30 with insulation, and effect as shown in Figure 2.This design can reduce summer tans by the sun the too low growth on wetland plant 19 and then the impact on wetland variation effect with winter temperature, ensures that water outlet reaches consumable water of sight and amusement standard, beautifies living environment simultaneously.
Wetland effluent 23 flows into the biological filter 27 under road surface, residential quarters, biological filter 27 profile is as waterways, using protruded ripple plate 26 as filler, protruded ripple plate 26 had both maintained certain porosity, the apposition growth of microorganism can be ensured again, substantially increase the degradation capability to dissolved substance, suspended substance and chemical-biological aerobic substance.
Biological filter water outlet 25 imports landscape pond 29, and this device water outlet reaches view recreational water standard.Hydrobiont 28 can be cultivated in landscape pond 29, prevent summer from growing mosquito.
