<p><P>PROBLEM TO BE SOLVED: To provide a water quality monitoring device capable of acquiring precisely a treating state, and showing surely treating performance, in a waste water disposal facility aiming at organic waste water. <P>SOLUTION: An excessive amount of sample waste water is supplied into a water feeder 20 whose water level is adjusted, and a part of the water is dropped down, and an excessive portion is discharged from an outflow port through a discharge means 28. A delivery port 26 wherein the water pressure is kept constant forms a 'nozzle', and the shape of the dropping water forms a stable 'water column', and passes a space of an inspection section 40. Each beam is generated successively from each light emitting diode (LED) 50 in three colors of R, G and B, and each beam is directly transmitted through the center of the 'water column' in the inspection section space, and received by a light receiving part photosensor 60, and a recording part 62 is allowed to function by the light receiving quantity and known data. Each water quality property such as each concentration, each chromaticity or color tone of SS, BOD and ammonia nitrogen can be acquired simultaneously from a change of absorbance. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
