The top of pipe is equipped with spoil disposal drain, in this way, can facilitate the discharge of sludge.
The sludge pipe is connected to mud return line, and under air-lift device cooperation, sludge can smoothly flow back.
It is separated between second aerobic unit and mud-water separation unit by partition, the partition includes
Upper and lower distribution first tilt clapboard and the second tilt clapboard, between first tilt clapboard and the second tilt clapboard there are
For the gap that sewage passes through, in this way, passing through for sewage not only may be implemented, can also to avoid sludgd deposition to aerobic zone with
The intersection region of mud-water separating area, avoids sludge from silting up；In addition the flow velocity for slowing down muddy water can also be played, keeps sludge sufficiently heavy
It forms sediment, enhances mud-water separation effect.
Combination is optimized to anaerobism, anoxic, aerobic process in the sewage disposal system of the utility model, and combines work
Property the techniques such as sludge, biofilm, filtering cloth filtering pool technical characterstic, there is strong impact resistance ability, easy to operate, operation and pipe
Manage easy to maintain, long service life, the advantages that sludge output is few, high treating effect, water outlet can reach " urban wastewater treatment firm pollution
Object discharge standard " (GB18918-2002) level-one B discharge standard, it is especially suitable for the processing of the water quality of domestic sewage in rural areas.
