Illustrate, in the sewage disposal system of the combining form, the treatment effect of each unit bed is different, but according to pollutant in system
In the analysis and research of mechanism of degradation can push away it, there is stronger mutual assistance and complementarity between sewage treatment unit beds at different levels, it is preceding
Face special use bed provides preferable pre-treatment for subsequent cell bed so that subsequent cell bed can more fully hereinafter play processing work(
Effect, simultaneously because system combines microorganism, high green plants root system, artificial base under anaerobism and oxygen and aerobic state
The assimilation of matter decomposes, shuts off, the treatment mechanisms such as absorption and sorption and filtering so that system has the removal of higher nitrogen and phosphorus effect
Rate.
