To good removal effect.
Spray process absorbs the harmful gas in waste gas by spraying clear water.This kind of method is simple to operate, but can only
Remove part water solublity waste gas in removing exhaust gas, bad for water-fast odorant evolution effect, absorbance
Have much room for improvement.
Bioanalysis, utilize biological life process that gaseous contaminant decomposition and inversion in waste gas is become less or even without
The material of evil.Simple biomembrane processes, and needs to hang substantial amounts of film, and reaction condition is wayward.
Industrial wastewater is carried out processing and has that following some is not enough: one by traditional handicraft, waste water through Sedimentation tank with
And after regulating reservoir processes, typically directly enter AO pond and carry out organic decomposition.Owing to being directly entered AO pond
Waste water do not carry out Oil-water separation, increased the weight of AO pond decomposition burden；Its two, containing substantial amounts of in waste water
Suspension granule, is suspended in waste water, not easy-clear.
