Classification of
waste water processing
- Biological processing (positive processing,
negative processing)
- Physical processing
- Chemical processing
Method of biological
waste water processing
The method of biological processing is a
method to use the microorganism to remove
the organic substance that can be integrated
and floating substance by microorganism
from the organic substance existing in sewer
water. The biological processing can be
classified into positive disintegration
and negative disintegration.
Principle of biological
waste water processing
- Positive processing : (CH2O)X + O2 ¡æ CO2
+ H2O + Cell + energy
- Negative processing : (CH2O)X + H2 ¡æ CO2
+ H2O + Cell + energy
Kinds of biological
waste water processing
- Positive processing : Activated sludge
approach, sterilization approach, plate
rotation method
- Negative processing : Storage tank
