Control system for biological nitrogen removal wastewater using low cost probes.

摘要

Control system for biological nitrogen removal wastewater using low cost probes. The present invention describes a control system based on fuzzy logic, which allows to optimize the biological removal of nitrogen in continuous processes with pre-denitrification regime circulation type plug flow or mixed reactors. If the reactors are complete mixing type must have at least two distinct zones aerobic and anoxic two distinct areas. When it comes to reactors plug flow type this differentiation is not required within each reactor (anoxic and aerobic). This control system is based on the use of low cost probes pH and ORP type.
