2. technical solution
In order to achieve the above objectives, technical solution provided by the invention is:
A kind of effective integrated sewage-treatment plant of the present invention, including hypoxic-ischemic brain-damage, the aerobic ponds MBBR and flocculation Dephosphorization pond is filtered, the bottom of the hypoxic-ischemic brain-damage is provided with water inlet pipe, the input terminal of water inlet pipe and hypoxic-ischemic brain-damage Connection, the output end of hypoxic-ischemic brain-damage are provided with the aerobic ponds MBBR, are provided between the aerobic ponds MBBR and hypoxic-ischemic brain-damage The output end of nitrification liquid return-flow system, the aerobic ponds MBBR is provided with flocculation filtration dephosphorization pond, the flocculation filtration dephosphorization Chi Bao Dosing pond and biological filter with oxygen are included, the input, output end in dosing pond connects with the aerobic ponds MBBR, biological filter with oxygen respectively Logical, the inside of biological filter with oxygen and hypoxic-ischemic brain-damage is installed with backwashing system, the outer surface of biological filter with oxygen Also it is installed with U-shaped outlet pipe, U-shaped outlet pipe and biological filter with oxygen piping connection.
Further, the biological filter with oxygen is Downward-flow biofilter, and hypoxic-ischemic brain-damage is upward flow biology The backwashing period of filter tank, hypoxic-ischemic brain-damage and biological filter with oxygen is 10H to 30H.
Further, the inside in the aerobic ponds MBBR is filled with filler, and filler accounts for the 20% of aerobic MBBR pool volumes To 60%.
3. advantageous effect
Using technical solution provided by the invention, compared with prior art, have the advantages that:
The present invention realizes denitrification by biofilters at different levels, has floor space compared with the denitrification pond of activated sludge process The big advantage of small, strong shock resistance, processing load, by dosing pond dosing chemical dephosphorization reinforced phosphor-removing effect, by preposition Denitrification process and denitrification process reach twin-stage denitrogenation strengthened denitrification effect, and practical water outlet flows through biological filter with oxygen, ensures The practical floor space for avoiding setting sedimentation basin while water outlet quality, reducing single unit system.
