Background technique
Traditional UASB reactor, high concentration organic sewage from reactor bottom enter, reactor bottom have one it is highly concentrated
It spends, the Sludge Bed of high activity, the majority of organic pollutants in sewage passes through hydrolysis-acidification-anaerobic fermentation degradation here
For biogas, mainly methane and carbon dioxide.Biogas is constantly released in the form of micro-bubble, micro-bubble in uphill process,
Constantly merge, gradually form biggish bubble, bubble plays agitaion to base sludge, promotes contact of the sewage with sludge anti-
It answers.
Sewage needs to consume basicity in the Hydrolysis Acidification of the bottom UASB, and PH can gradually decline in water, especially handle
High concentration organic sewage, the basicity for needing to consume is very high, needs largely to add alkali in water inlet, to maintain the alkalinity demand of UASB.
In water inlet largely plus alkali, cause (sometimes for PH10~11 are reached) very high into water pH value, thus in UASB pH value by down toward
On be gradient distribution from high to low, be unfavorable for growth, the breeding of anaerobic bacteria in UASB, the suitable model of anaerobic bacteria growth in this way
