Abstract

A/O biological biologic denitrifying reactor, adjustment of nitration process, its fuzzy on-line controller and controlling method are disclosed. The process is carried out by stirring in oxygen-deficient area continuously, denitrifying reacting, aerating in oxygen area continuously, enlarging opening of aerator air intake valve with higher ammonia nitrogen water charge load or lower ammonia nitrogen outfall concentration, decreasing opening of aerator air intake valve reversely, shutting or opening air intake vale with different grid chambers, opening or shutting stirrer in related reaction pool, and enlarging or decreasing opening of refluxing mud valve to adjust mud concentration in reactor. It achieves higher efficiency and less consumption.

Description

technical field [0001] The invention relates to a sewage treatment process and its control device and method, in particular to a continuous flow biological denitrification process nitrification device and method and its intelligent control device and method. Background technique [0002] With the development of the economy and the improvement of human living standards, the water consumption has increased rapidly, and the sewage discharge has also increased accordingly, which has exacerbated the shortage of water resources and the eutrophication of water bodies. Eutrophication is one of the most important water pollution problems facing the world today. In recent years, although my country's sewage treatment rate has continued to increase, the eutrophication problem caused by nitrogen and phosphorus pollution has not only not been resolved, but has become increasingly serious. It can be seen that the main contradiction of sewage treatment has gradually changed from the remov...
