The biofilm reactor stood first in stability towards substrate shock load, followed by anaerobic sequencing batch reactor (SBR) and the granular sludge bed.

Start-up of expended granular sludge bed reactor start-up for terylene artificial silk printing and dyeing wastewater treatment.;

Indication effect of oxidation reduction potential to expended granular sludge bed reactor

Kinetic model for settling of granular sludge;

Microbial community structure in simultaneous methanogenesis and denitrification granular sludge;

Start-up of UASBF for landfill leachate disposal and culture of granular sludge;

The time to form granule sludge was shorten from 53.

The micro-ecological characteristics of granule sludge in Anaerobic Baffled Reactor(ABR) was investigated with constructed wastewater of glucose and domestic sewage as feed substrate, and the clearly phase separation shown by different priority anaerobic microbes of granular sludge in the compartments of different micro-environment along the ABR was observed.

According to the data,the UBF reactor can start up quickly by taking the remained granule sludge from UASB reactor as seeds.

d);the phenomenon of hydraulic grade which the increase of the hydraulic loading rate lead to help sludge grow;the high fume loading rate had an effect on mixing and sludge granulation.

Research of Applying Granule in Wastewater Treatment Processes;

Analyzed the importance of granule and biofilms for increasing anaerobic biomass activity through reactor startup, biomass acclimation, biomass communal synergism, H_2 management options.

The excellent performance of these reactors relies on granules of excellent bio-activity and high settling ability as well as enhanced mass transfer rate which is induced by the strong hydraulic condition.
