Specific embodiment
The specific embodiment of the present invention is the following is, technical scheme is described further, but the present invention Protection domain is not limited to these embodiments.Every change or equivalent substitute without departing substantially from present inventive concept is included in the present invention Protection domain within.
As shown in figure 1, a kind of recycled water feeds the ecological treatment apparatus of landscape water, package unit locates below ground level, and wraps Include pretreatment pool 7, Anaerobe pond 10, Artificial subsurface flow wetland 18, biofilter 27 and landscape pond 29, the pretreatment pool 7 Near residential quarters building drainage system, the Anaerobe pond 10 connects pretreatment pool 7, Anaerobe pond 10 and pretreatment pool Downflow weir 8 is provided between 7, downflow weir 8 is provided with spout hole 9, and the anaerobic pond water outlet 11 in the Anaerobe pond 10 is latent with artificial The wetland water inlet 12 of stream wetland 18 connects, and the Artificial subsurface flow wetland 18 is arranged on around the building of residential quarters, described artificial latent The wetland effluent 23 of stream wetland 18 is connected with the biofilter water inlet 24 of biofilter 27, and the biofilter 27 is arranged on house Under cell road surface, the biofilter water outlet 25 of the biofilter 27 is connected with landscape pond 29, and the landscape pond 29 is arranged Residential quarters are central or low-lying place.
Specifically, 7 top of the pretreatment pool is provided with wastewater influent 1, is provided with hand basket fine fack 2 and holds in pretreatment pool 7 Prop barrel 4, hand basket fine fack 2 are hung on support bucket 4, and the support bucket 4 is supported by bucket edge and support point 6, the bottom of the support bucket 4 Plate is the poroid supporting plate 5 of live-in with bayonet, and filter membrane 3 is posted on supporting plate 5.
Specifically, the 12 adjusted ponds 13 of wetland water inlet are connected with one end of Artificial subsurface flow wetland 18, described artificial latent The other end Jing collecting-tanks 22 of stream wetland 18 are connected with wetland effluent 23.
Specifically, the Artificial subsurface flow wetland 18 is that one group or several groups of strips spend pond, inwall to do water-proofing treatment, and two ends are by outer 15 filter material layer of cobble 14 and Vermiculitum is filled inwardly, the underfill of the Artificial subsurface flow wetland 18 has substrate, and Medium Culture kind is implanted with Wetland plant 19, the substrate are followed successively by turfy soil 16, canebreak 20, haydite 21 from the bottom to top.
Specifically, the Medium Culture is vertically provided with multiple flaps 17, and 19 kinds of wetland plant is planted between flap 17.
During operation, 1 Jing hand baskets fine fack 2 of wastewater influent and filter membrane 3 are filtered into pretreatment pool 7,3 mistake of sewage Jing filter membranes Filter, can remove more than 30% organic pollution, and the float, solid particle and part macromole zoogloea in sewage can not be led to Filter membrane 3, effectively alleviates the silting of wetland 18, also greatly reduces the degraded load in Anaerobe pond 10.
Filter water Jing downflow weir 8 enters Anaerobe pond 10, and in pond, temperature is more constant, is not easily susceptible to extraneous air, temperature Degree influence of fluctuations, provides good breeding place for anaerobic bacteria, amphimicrobe and Ammonifying bacteria.In Anaerobe pond 10, Sewage is carried out into sufficient anaerobic hydrolysis-acidification, the wherein Organic substance of macromolecule difficult degradation can be completely reformed into low molecule substantially The Organic substance being easily degraded, improves the ratio of BOD/COD in sewage, is conducive to the absorption and degraded of wetland plant 19.
Water outlet 11 adjusted pond 13 in Anaerobe pond enters Artificial subsurface flow wetland 18, and different substrate is beneficial to not of the same race The silting of wetland 18 also can be effectively alleviated in the existence of quasi-microorganism, Vermiculitum 15 with haydite 21.Wherein 16 layers of turfy soil did not had plant Fibrous root, middle folder 20 thin layer of canebreak, top covers 21 layers of haydite.Before 19th floor, wetland plant or area without shade plantation flag flower, Roadside or shady spot's plantation cyperus alternifolius.Evergreen aquatic Rhizoma Iridis Tectori cold hardiness is strong, and metabolism is vigorous, even if in the winter time, can also inhale Effect is played in terms of receiving water pollutant;And after sewage stops 10d in the wetland of plantation cyperus alternifolius, TN in sewage, TP, COD, BOD clearances can reach 70~90%.Wetland plant 19 in addition to the direct absorption of pollutant, also important indirect work With:Oxygen is transported to into plant root from top, so as to plant root formed an aerobic environment, with a distance from root system by It is cumulative big, occur anoxia, anaerobic state in wetland successively, such condition is conducive to the growth of nitrifier and denitrifying bacterium, enters And strengthen the effect of wetland microorganism nitrification and denitrification, improve the purification efficiency of N in sewage.Artificial subsurface flow wetland 18 also has to P Preferably removal effect, depends primarily on the collective effect of plant absorption, the adsorption filtration of substrate and microorganism conversion three.People Microorganism in work current wetland 18 can also eliminate the abnormal flavour of sewage.18 operational mode of Artificial subsurface flow wetland is designed to vertical folding Stream wetland, i.e., add flap 17 inside the wetland, allows current flow process is elongated, and fluidised form is more uniform, so as to improve during hydraulic retention Between, increase pollutant with filler, root system of plant and biomembranous time of contact in wetland so that remove the thing needed for pollutant Reason, chemistry and biological respinse carry out more abundant, and the more common wetland of pollutants removal rate is significantly improved.Wetland moisturizing can basis Practical situation takes the mode of intermittent moisturizing.18 top summer of Artificial subsurface flow wetland arranges Caulis wisteriae sinensiss frame 31 and supplies sun-proof, and effect is such as Shown in Fig. 3;Winter frame covers closed transparent plastic greenhouse 30 to be incubated, and effect is as shown in Figure 2.The design can reduce summer exposure with The too low growth to wetland plant 19 of winter temperature and then the impact to wetland variation effect, it is ensured that water outlet reaches landscape amusement Water supply standard, while beautifying living environment.
Wetland effluent 23 flows into the biofilter 27 under the road surface of residential quarters, biofilter 27 profile such as gutter, with many Hole corrugated plating 26 had both maintained certain porosity as filler, protruded ripple plate 26, can guarantee that the apposition growth of microorganism again, Substantially increase the degradation capability to dissolving material, float and chemical-biological aerobic substance.
Biofilter water outlet 25 imports landscape pond 29, and the device water outlet reaches landscape amusement water quality standard.Landscape pond 29 It is interior to cultivate aquatile 28, prevent summer from growing mosquito.
