Title:
SEWAGE DISPOSAL SYSTEM AND MEASURING SYSTEM
Document Type and Number:
Japanese Patent JP2001353496
Kind Code:
A
Abstract:

To provide a sewage disposal system which is capable of performing sewage disposal control by taking an inflow rate and water quality into consideration as load fluctuation elements of sewage.

The sewage disposal system 10 has a biological reaction chamber 12, an air diffusion device 16 installed in the biological reaction chamber 12 and an aerator 15 connected to the air diffusion device 16. The biological reaction chamber 12 is internally provided with an ammonia meter 45 and the inlet of the biological reaction chamber 12 is provided with a flow meter 35. An aeration air quantity is determined in an aeration air quantity computing section 41 of a controller 40 in accordance with the signal from the flow meter 35. A correction factor is determined by a correction factor computing section 42 in accordance with the measured value from the ammonia meter 45 and the aeration air quantity of the aeration air quantity computing section 41 is determined by this correction factor.
