WATER QUALITY MEASURING DEVICE AND WATER QUALITY MONITORING SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a small-sized device to be arranged near a terminal end of a distributing pipe for a drinking water and to detect a plurality of items by feeding a plurality of liquids containing a sample water from a plurality of feeding passages to an analysis part. SOLUTION: A drinking water (sample water) 52 flowing in a distributing pipe 52 is introduced from a piping 57 to a defoaming tank 66 through a filter 63 and a passage 65 and a bubble 67 in the sample water 52 is disposed from a mother board 101 to a drain ditch 60. The sample water 71 after removing the bubble is selectively fed from a continuous blow pump 74 to analysis parts 76-78 for analyzing independent items through solenoid valves 75a-75c and introduction holes 71a-71c. A plurality of cartridges 79-81 retained at the outside of the mother board 101 feeds each liquid, i.e., a reagent 82, a washing water 86 and a zero water 89 to the mother board 101 and they are selectively fed to each analysis part. Each analysis part comprises a reagent-mixing portion for mixing or selecting and reacting each fluid and a measuring/ analyzing portion. The analysis parts have a function of one small-sized analyzer and a waste liquid 92 is discharged to the outside of the device through a flow passage 70.
