The risk assessment of drinking water source focused on quantitative assessment of contaminants detected in drinking water on human health risks, but the potential environmental risk assessment of source drinking water protection is rare research. Therefore, in this paper, expert systems and AHP were introduced into the conventional fuzzy comprehensive evaluation in order to improve the degree of...
The effect of the DO concentration on the stability of the shortcut nitrification was studied. The static test is done with SBR reactor. Reaction time reduced with the DO concentration raised appropriately, but DO in excess, the shortcut nitrification system will be damaged by the analysis of the impact of DO concentration on ammonia removal, nitrite nitrogen accumulation in shortcut nitrification...
The purpose of this study is to remove TN of landfill leachate by the conventional treatment-A2O under the new Standard for Pollution Control on the Landfill Site of Municipal Solid Waste (GB16889-2008). Explore the conventional process for denitrification of landfill leachate treatment, and the best craft and working conditions. Through long-term experiment to prove the conventional technology of...
The simultaneous biological removal of iron, manganese and ammonia from simulated contaminated groundwater was studied by biological aerated filter using dual layer ceramsite as support material in the lab. The system was simultaneously inoculated with iron and manganese oxidizing bacteria, nitrifying bacteria and nitrification bacteria and a series of experiments was performed to investigate simultaneous...
