Gap between said each flow deflector bottom surface and the buried unpowered biological reactor drum inner bottom surface is the particle diameter less than filler, promptly should avoid filler from said gap, to pass through.
Filler in said each chamber can specifically be selected according to the situation of processing sewage, and preferred, the filler in first chamber is a 3 D elastic filler, and the filler of second chamber and the 3rd chamber is no excess sludge suspension type biological filler.
Said undercurrent composite type artificial wetland is provided with four levels from bottom to top and joins filler, is respectively bamboo carbon layer, metalling, zeolite layer and dirt bed.Can on the dirt bed of its superiors, plant plant, reach the purpose of viewing and admiring.
Compared with prior art, the said treatment system of the utility model adopts unpowered buried bio-reactor, when not influencing surrounding enviroment, effectively removes organic pollutant and suspended solids in the sewage; Remove nitrogen, phosphorus nutrition material in the sewage through the undercurrent composite type artificial wetland, also can plant landscape plant above that to beautify the environment; Last water outlet form adopts landscape ecological pool overflow, and further removes ammonia, nitrogen through waterplant such as the duckweed in the view pool, Herba Eichhorniae and fish etc., and removes pathogenic micro-organism and algae in the sewage, reaches the purpose of sterilizing and purifying.Entire treatment system non-power consumption, operation does not need personnel operation, does not influence ecoscape; Water quality after this system handles reaches or is superior to the one-level A standard among " urban wastewater treatment firm pollutant emission standard " (GB 18918-2002).
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of unpowered ecological treatment system of the said processing domestic sewage in rural areas by using of the utility model.
Label is among the figure:
1 buried unpowered biological reactor drum; 2 undercurrent composite type artificial wetlands; The 3 landscape ecological pools; 43 D elastic fillers; 5 flow deflectors; 6 no excess sludge suspension type biological fillers; 7 baffle plates; 8 bamboo carbon layers; 9 metallings; 10 zeolite layer; 11 dirt beds.
Embodiment
As shown in Figure 1, the unpowered ecological treatment system of the said processing domestic sewage in rural areas by using of the utility model comprises buried unpowered biological reactor drum 1, undercurrent composite type artificial wetland 2 and the landscape ecological pool 3 of using pipe connection successively.
Wherein, One side of said buried unpowered biological reactor drum 1 offers water-in; Opposite side offers water outlet; Described water-in and water outlet all are opened in the middle and upper part of buried unpowered biological reactor drum 1, in buried unpowered biological reactor drum 1 set inside first flow deflector 5 and second flow deflector 5 are arranged, and all and between the inner bottom surface of buried unpowered biological reactor drum 1 there is the gap in the bottom surface of described first flow deflector 5 and second flow deflector 5; Thereby buried unpowered biological reactor drum 1 is separated into first chamber, second chamber and the 3rd chamber that the bottom is interconnected; All be filled with filler in each chamber, filler can specifically be selected according to the situation of processing sewage, in this embodiment; Filler in first chamber is that the filler of 3 D elastic filler 4, the second chambers and the 3rd chamber is no excess sludge suspension type biological filler 6; Side near second flow deflector 5 in said second chamber is provided with baffle plate 7, and this baffle plate 7 has only its bottom surface and former and later two sides thereof to be connected with the inner-wall surface of buried unpowered biological reactor drum 1 respectively, and this connection should be seamless link.
The size in gap should be to let water pass through between said first flow deflector 5 and second flow deflector, 5 bottom surfaces and buried unpowered biological reactor drum 1 inner bottom surface, but can not let filler pass through.Usually, the vertical height in this gap should be less than the particle diameter of filler.
The water-in of said undercurrent composite type artificial wetland 2 and water outlet all are located at the middle and lower part of undercurrent composite type artificial wetland 2; Four levels being set in undercurrent composite type artificial wetland 2 from bottom to top joining filler, is respectively bamboo carbon layer 8, metalling 9, zeolite layer 10 and dirt bed 11.
The pool body on the described landscape ecological pool 3 is ladder structure; (pool body water level is more shallow for the dark 0.5~1.0m in the pool; Help airborne oxygen from being advanced into water body, further remove ammonia, nitrogen in the water), put various fish in the pool in a suitable place to breed; Pool periphery is laid plants such as duckweed, Herba Eichhorniae from shallow to deep respectively, to remove pathogenic micro-organism and algae in the sewage.
The detailed process of the said system handles sewage of the utility model is:
Sewage is flowed through grid after first chamber of the buried unpowered biological reactor drum 1 in water-in inflow place of buried unpowered biological reactor drum 1; In the process of falling, contact with 3 D elastic filler 4; Flow into second chamber in the gap that constitutes by first flow deflector, 5 bottom surfaces and buried unpowered biological reactor drum 1 inner bottom surface then; Owing to be provided with baffle plate 7 in this chamber; Therefore current can not directly flow into the 3rd chamber from the gap of second flow deflector, 5 bottom surfaces and buried unpowered biological reactor drum 1 inner bottom surface formation; Have only when the water level in second chamber reaches baffle plate 7 vertical height, current could get into the passage that is made up of the baffle plate 7 and second flow deflector 5, flow into the 3rd chamber then; It is thus clear that a side that in second chamber, is provided with near second flow deflector 5 is provided with the duration of contact that baffle plate 7 has effectively increased sewage and filler, thereby can better remove organic pollutant and suspended solids in the sewage.Get into undercurrent composite type artificial wetland 2 through piping by the water-in of undercurrent composite type artificial wetland 2 bottoms by the effusive current of the 3rd chamber; By descending from last bamboo carbon layer 8, metalling 9, zeolite layer 10 and the dirt bed 11 of passing through successively; Pollutent in undercurrent composite type artificial wetland 2 through effects such as filtration, absorption, plant absorbing and biological degradations; Make nitrogen, phosphorus removal effect give prominence to; Can and go through flower again wetland the superiors plantation Canna generalis Bailey, can remove pollutants in sewage matter and can beautify the environment again.The effusive current of water outlet by undercurrent composite type artificial wetland 2 bottoms get into the landscape ecological pool 3 at last, remove pathogenic micro-organism and algae in the sewage through animal in the landscape ecological pool 3 and plant, reach the purpose of sterilizing and purifying.
