Features and application of anaerobic sequencing batch reactor;

Hydraulic retention time of sequencing batch reactor;

The effects of dissolved oxygen concentration and influent carbon to nitrogen ratio on nitrogen removal performance of a wastewater containing strength ammonia nitrogen were investigated in a sequencing batch reactor.

Taking effluent from anaerobic hydrogen-producing reactor as substrate,the cultivation process of aerobic granular sludge in a sequencing batch reactor(SBR) was studied.

Enriched effective microorganisms(EM) cultivation liquid was added into sequencing batch reactor(SBR) and sequencing batch biofilm reactor(SBBR) respectively to form the new-type wastewater treatment equipment(EM-SBR and EM-SBBR).

Development of the SBR System Simulation Model;

The sequencing batch reactor(SBR) was modified based on its hydraulic characteristics.

Study was made on the characteristics and control condition of short-cut nitrification in SBR at low DO,and the effect of carbon source concentration and dosing mode on efficiency of simultaneous denitrification.

Study on performance characteristics of membrane sequencing batch reactor;

Nitrogen removal performance was investigated using synthetic wastewater as feed without sludge discharge in an anaerobic/aerobic membrane sequencing batch reactor (MSBR) during 300 days operation.

Sequencing batch reactor (SBR), because of the characteristics of good effects of nitrogen and phosphorus removal and taking up small area, obtained widespread concern and has be applied universally.
