Operation and analysis of modified AB process for removal of nitrogen;

Effect of sulfur contained substances in wastewater on AB process;

Problems and countermeasures of AB process in Zibo Wastewater Treatment Plant;

Because it has the nature of saving energy, high compatibility of water quality chang, high capability of treatment burden, it is widely used in recent years, the operation experience of AB craft in He-dong sewage disposal plant shows that it is a good craft used to treat urban sewage.

This paper expatiates on the principle of AB craft and the characteristics of A2O craft.

According to the characteristics of wastewater from the process of dioscorea zingiberensis,this paper studies the operation of the process in A-B process,analyzes the experimental data,and concludes the industrial flow and technological parameters of A-B process.

This paper systematically analyzes the mechanism and the feature of A B process,shows the limitation of A B process in biological nitrogen and phosphate removal,discusses the ways of improving the nitrogen and phosphate removal about A B process.

A modified AB process was used to treat municipal sewage in this paper in order to improve nitrogen and phosphorus removal efficiency by the traditional AB process.
