The described height that separates the cutoff board upper end in aerobic nitrification district and sludge settling district will be lower than the height of water outlet overflow weir upper end, and near the height of the traverse baffle lower end being higher than guarantees the mud circulation.
The setting of described mudhole height is an important parameter of decision aeration tank sludge concentration, can after having determined the aeration tank sludge concentration, design the height of mudhole, the staff only needs mud is discharged to mudhole during commencement of commercial operation in the future, generally mudhole is located at 1/4-1/3 place, sludge settling offset bottom and is advisable.
The angle setting of described bucket swash plate is to enter the aeration zone then in order to make mud after the sludge settling district mud-water separation be slipped to the bottom, settling region automatically, so its swash plate angle becomes the 100-125 degree to be advisable with level.
The rising compartment in the described anaerobism de-carbon district and the width of decline compartment are than being 1-5: 1, the de-carbon effect in anaerobism de-carbon district mainly relies on the rising compartment, the decline compartment has guide functions, be used to prolong flow path, strengthen sewage and fully contact attached to the microorganism on the Ball-type packing, therefore need suitably adjust 1-5 for the width ratio of rising compartment and decline compartment: 1 ratio can satisfy treatment effect, can improve the overall treatment efficiency of device again.
Successively spread slabstone, coarse sand and fine sand in the vegetation region of described ecological wetland, plants such as the plantation stem or leaf of cattail, reed on it.
Available concrete etc. is built around the described ecological wetland, avoids water to flow out ecological wetland.
In anaerobism de-carbon district, the main baffling up and down that adopts prolongs flow path, strengthens sewage and fully contacts attached to the microorganism on the Ball-type packing.
In aerobic nitrification district and sludge settling district, adopt the automatic reflux of mud of unique design, muddy water thorough mixing with the aerobic nitrification district, the mud-water separation in sludge settling district and automatic sludge returning are molten to the bottom, settling region to be one, adopt solar electrical energy generation to drive the aerator in aerobic nitrification district, really accomplish cleaning, do not have power consumption.
In the ecological wetland district, adopt the biological natural purifying ability of plants such as the stem or leaf of cattail, reed, mainly utilize physics, chemistry, the biological triple synergies of soil, artificial dielectric, plant, microorganism, sewage, mud are further handled.Also avoided sewage, mud etc. to contact, protected solar panel with the unnecessary of solar panel.
Compare with traditional technology, the utility model device has and does not have power consumption, effectively removes that multiple pollutent, mud in the sanitary sewage need not to reflux, the advantage of mud minimizing to greatest extent, greening environment, adopt biological natural purifying ability further to remove nitrogen, phosphor contaminant in the sewage, energy-conservation, greening that meets that China payes attention at present gradually and nitrogen, phosphorus pollute the theme of removing.
