Based upon study of the gas flowrate changes of filler under various filling rates,submersion depth,microporous and single orifice aeration ways,different aeration density and other conditions the hydraulics characteristics of HSL aerobic biological fluidized bed is studied,which provide good references for optimization design of HSL aerobic biological fluidized bed and similar reactors.

Treatment of propylene epoxide saponated sewage by deep well aeration biological process;

According to the characteristics of the wastewater from papermaking, combined with the technological advantages of activated sludge process with deep well aeration, it is suggested that deep well aeration is promising and applicable for the wastewater treatment in pulp and papermaking industry.

,Ltd was treated by deep well aeration technics with strong appliance,good treat effect and stable operational effect.

of using submerged aeration to enhance the efficiency of waste water treatment by demolishing the original rotating biological disc.

Therefore, it was necessary to carry out renovation on the existing treatment process, mainly including the use of UASB reactor, SBR, and deep shaft aeration tank; of which two-phase anaerobic process was used in UASB reactor to eliminate the effect of sulfate on anaerobic process.

Calculation of air volume in deep-well aeration;
