PHOSPHORUS REMOVING SUPPORTING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a phosphorus removing supporting apparatus which easily and quantitatively estimates the deterioration of the removal of phosphorus due to rainfall. SOLUTION: The phosphorus removing supporting apparatus is equipped with a first sedimentation basin in which raw water flows, a biological reaction tank having an anaerobic tank and an aerobic tank in which sewage treated in the first sedimentation basin flows and a second sedimentation basin in which sewage flows from the biological reaction tank. This apparatus is equipped with the phosphorus meter provided in the first sedimentation basin, a rain gauge provided in the treatment region of the apparatus, a water temperature meter for measuring the temperature of raw water flowing in the apparatus, an arithmetic unit for estimating the concentration of the organic acid of the apparatus on the basis of the measuring signal of the water temperature meter and the rain gauge and estimating the deterioration level of the removal of phosphorus from the organic acid concentration level and the measuring signal of the phosphorus meter and a display device for displaying the operation result of the arithmetic unit on the basis of the signal from the arithmetic unit.
