described subsection water inflow A/O composite sewage treatment equipment, described settling tank comprises preliminary sedimentation tank, and described preliminary sedimentation tank communicates with settling pit, and described settling tank inside is provided with into water perforated pipe, and described settling tank connects shore pipe.
described subsection water inflow A/O composite sewage treatment equipment, between the joint flange of described settling tank and described Aerobic Pond, graticule mesh is installed, between joint flange between described Aerobic Pond, graticule mesh is installed, graticule mesh between the joint flange of described Aerobic Pond and described anaerobic pond.
described subsection water inflow A/O composite sewage treatment equipment, described Piecewise Water Distribution device has rising pipe.
beneficial effect:
the utility model efficient coupling A/O technique and MBBR technique, and segmental influent distribution technique, active sludge-microbial film cogeneration system, low-power consumption sludge/nitrification liquid technique of backflow are integrated in overall craft, and then enhanced system is to the adaptability of change of water quality, the operation stability of raising system under low-temperature condition, consolidation system synchronous nitration and denitrification usefulness, ensures organic matter removal ability and total nitrogen, the ammonia nitrogen removal efficiency of efficient stable under all weather conditions.
the utility model is on the basis of traditional A/O technique and MBBR technique, the two technology unit is carried out efficient coupling, and segmental influent technology and active sludge-microbial film cogeneration system are integrated in overall craft, build the compound MBBR wastewater processing technology of subsection water inflow A/O.
accompanying drawing illustrates:
accompanying drawing 1 structural representation of the present utility model.
accompanying drawing 2 is vertical views of accompanying drawing 1.
accompanying drawing 3 is structural representations of Aerobic Pond one.
embodiment:
embodiment 1:
a kind of subsection water inflow A/O composite sewage treatment equipment, its composition comprises: settling tank 1, described settling tank communicates with automatic paragraphing water dispensing apparatus 2, described automatic paragraphing water dispensing apparatus and inside return to pond 3 and communicate, described inside returns the Aerobic Pond that Chi Yuyi group connects in turn and communicates, described Aerobic Pond inside has anaerobic activated sludge microbial film 15, diving mixer 16, side direction aeration perforated pipe 17, and its inside adds the modification biological floating stuffing of anerobe attachment, and the described Aerobic Pond being positioned at least significant end communicates with anaerobic pond 4.
described Aerobic Pond comprises: Aerobic Pond 1, Aerobic Pond 26, Aerobic Pond 37, Aerobic Pond 48, Aerobic Pond 59, the structure of these five Aerobic Ponds is identical.
embodiment 2:
subsection water inflow A according to embodiment 1/O composite sewage treatment equipment, described settling tank comprises preliminary sedimentation tank 10, described preliminary sedimentation tank communicates with settling pit 11, and described settling tank inside is provided with into water perforated pipe 12, and described settling tank connects shore pipe 13.
embodiment 3:
subsection water inflow A according to embodiment 2/O composite sewage treatment equipment, between the joint flange of described settling tank and described Aerobic Pond, graticule mesh is installed, between joint flange between described Aerobic Pond, graticule mesh is installed, graticule mesh between the joint flange of described Aerobic Pond and described anaerobic pond.
embodiment 4:
subsection water inflow A according to embodiment 2 or 3/O composite sewage treatment equipment, described Piecewise Water Distribution device has rising pipe 14.
embodiment 5:
a sewage water treatment method for subsection water inflow A/O composite sewage treatment equipment that one of embodiment 1-4 is described, the method comprises the steps:
