Embodiment 2
[0040] A biochemical sewage treatment transformation process, comprising the following steps:
[0041] (1) Sewage pretreatment
[0042] First, the sewage enters the coarse screen through the pipeline, and then it is lifted into the fine screen through the lifting pump room to initially filter out the large-volume waste;
[0043] (2) Precipitation removal
[0044] The pretreated sewage is precipitated to remove impurities through a cyclone grit chamber, and the precipitation time is 40 minutes;
[0045] (3) Biochemical treatment
[0046] The sewage after the sedimentation is removed enters the biochemical treatment ditch through the water distribution well for biochemical treatment, and the biochemical treatment ditch is an anaerobic pond and an oxidation ditch;
[0047] (4) Precipitation treatment
[0048] Then the biochemically treated sewage enters the secondary settling tank through the water distribution well, the sludge in the secondary settling tank enters the mud st...
