Biochemical treatment workshop section includes:
Contact-oxidation pool provides air by blower, is completely removed using a large amount of microorganisms adhered on high-performance bio filler Organic matter in sewage, water outlet enter secondary settling tank, carry out mud-water separation, and processed sewage enters intermediate pool, sludge into Enter sludge-tank, which is respectively CODcr:80%, BOD5: 80%~90%, SS:80%, NH3- N:90%, TN:60%~80%, TP:60%~70%
Advanced treating workshop section includes:
Water into intermediate pool enters after current wetland further purifies sewage and enters drainage pipeline networks or gutter and discharge, Workshop section's contaminant remaining removal rate is respectively CODcr:60%, BOD5: 50%, SS:65%, NH3- N:60%, TP:70%;
Treatment of Sludge workshop section includes:
Secondary settling tank sludge a part is back to hydrolysis acidification pool, remaining sludge is promoted to sludge-tank through sludge lifting pump and carries out Digested, the supernatant of sludge-tank is back to conditioning tank.
According to the above aspect of the present invention, by extremely frigid zones treatment method for rural sewage, it can guarantee height above sea level, high latitude, throughout the year The wastewater treatment efficiency in the area that low temperature, frozen soil are not changed throughout the year.
The above description is only an overview of the technical scheme of the present invention, in order to better understand the technical means of the present invention, And can be implemented in accordance with the contents of the specification, the following is a detailed description of the preferred embodiments of the present invention and the accompanying drawings.
