The process description of this sewage disposal system is as follows
Sewage collects by entering collecting-tank behind thick lattice column, so as to which a large amount of larger impurity in sewage are stopped by thick lattice column
Water in pond is entered back into primary sedimentation basin, i.e., sewage is first in dynamic precipitation interval, and progress is preliminary in dynamic precipitation is interval
Precipitation after, sewage is entered in settling zone in meditation by filter screen, is splash due to not having water in quiet precipitation interval, sewage also will not
There is a larger flowing, therefore the whole interval deposition efficiency of quiet precipitation is high, by netted cover plate by the sludge in quiet precipitation interval
Separate with sewage so that sewage is precipitated by entering exhalant region after cover plate and being expelled to from sedimentation basin delivery port in aeration tank
The sludge got off enters sludge dewatering equipment by sludge outlet, in the presence of sludge dewatering equipment, realizes that sludge is utilized.
Sewage enters behind aeration tank, is handled by pure oxygen aeration, by the organic matter removal in sewage, after handling again afterwards
Sewage be discharged into secondary sedimentation tank, because the structure of secondary sedimentation tank is as primary sedimentation basin, therefore repeat no more, it is necessary to say
Bright, the sludge in secondary sedimentation tank is discharged into after primary sedimentation basin is precipitated again enters sludge dewatering equipment, realizes sludge
Reclaim.Afterwards, sewage sequentially enters sterilization pool and absorbent charcoal adsorption tank, last clear water discharge again.
