Taking active carbon and ceramics grain as vector particles,using the method of fast discharging sludge and forming biofilm,the inlet air and wastewater were enlarged gradually until the concentration of COD of outlet reach the low level.

Taking activated carbon as biological carrier,using the method of fast discharging sludge and forming biofilm,domestic sewerage were treated by the technology of three-phase bio-fluidized bed.

Research on the improvement mechanism of PVC bio-carrier surface forming biofilm property by remote argon plasma;

Study on effcet on BAC start-up of preoxidation by permanganate composite chemical;

Experimental study on the start-up of trickling biofilter with ceramic sphere and the purification performance for toluene waste gas;

Experimental research on three start-up methods of aerobic filters;

In this paper,the effects of different packing materials,different inoculation sludge on the biofilm culturing of effective microorganism (EM) biological contact oxidation reactor are studied.

With the wastewater from a brewery as an example, studied was the effect of different filling materials and different inoculation sludge on the biofilm culturing and starting process of the Effective Microorganism (EM).

The water temperature,air/water ration and influent ammonium loading rate(ALR) were the main factors for biofilm culturing and reactors startup.

Theexperiment shows that the pore gradient ceramics with the immobilization of biofilm has high porosity, largeratio surface area, excellent properties of biofilm formation, low losses of pressure, highly transmittingvelocity and media convey efficiency.

The effects of hydraulic retention time,reactor structure, sludge inoculation concentration and carrier size on biofilm formation on carrier surface in an internal loop biofluidised bed were studied.

The regularity of kinetics parameters was determined and biofilm surface was observed through microscopes during biofilm formation in nitrification filters by cinder and zeolite media.
