PROBLEM TO BE SOLVED: To provide a continuous monitoring method of water quality which enables the easy and rapid judgment of the pollution of water to be inspected before the behavior of aquatic life changes immediately after a pollutant such as a toxic substance or the like gets mixed in the water to be inspected. SOLUTION: Aquatic life is preliminarily bred in a water tank 1 through which water to be inspected is passed and, when the presence of the pollution of the water to be inspected is monitored while sampling the voltage output across a pair of electrodes 13a and 13b at a predetermined sampling cycle, the pollution possibility of the water to be inspected is judged when the voltage output changes suddenly before the active potential of the aquatic life changes. Platinum oxide or a coating material of platinum oxide is used in the electrodes 13a and 13b. Further, a pair of the electrodes 13a and 13b are arranged in the flow direction of the water to be inspected. COPYRIGHT: (C)2007,JPO&INPIT

PROBLEM TO BE SOLVED: To rapidly and properly specify a discharge source causing an abnormal high concentration of a chemical substance inside a river. SOLUTION: A CPU 11 of this chemical substance discharge amount calculation device 1 reads a chemical substance concentration and flow-down information in an observation section (reach) of the river, and a normal-time discharge amount of the chemical substance from the discharge source into a data storage area 13a from an external storage device 16. A water quality concentration computational expression that is an approximate expression representing relation between a water quality concentration and an abnormal-time discharge amount of the chemical substance from the discharge source is generated by use of the flow-down information, in each the reach. the abnormal-time discharge amount in each discharge source is calculated such that a total square of (the normal-time discharge amount - the abnormal-time discharge amount) in each discharge source becomes minimum, on the basis of the water quality concentration expression generated in each reach.

PROBLEM TO BE SOLVED: To provide a device for monitoring water quality capable of accurately judging the abnormality of water quality without causing the determination mistake of the abnormality of water quality even if specific conditions other than the abnormality of water quality occur, and to provide a method of monitoring water quality. SOLUTION: The device is constituted so as to capture and analyze the image of the fish housed in a water tank 1 to monitor the water quality in the water tank 1 and composed of an advance direction operating means for calculating the advancement direction of the fish from a plurality of captured images a direction change quantity operating means for calculating the change quantity in the advance direction of the fish on the basis of the advance direction calculated by the direction change quantity operating means, a change quantity averaging means for calculating the time average value of the change quantity in the advancement direction calculated by the direction change quantity operating means and a water quality determination means for determining water quality on the basis of the time average value of the change quantity in the advancement direction calculated by the change quantity averaging means.

PROBLEM TO BE SOLVED: To automatically monitor the PCB, heavy metal, etc., at all times and to control them on a real-time basis. SOLUTION: The waste water monitoring system and waste water treating system consist of a turbidimeter 1, a pH meter 2 for measuring the pH value, a PCB detecting means 3 for obtaining the PCB concn. from the turbidity, a heavy metal detecting means 4 for obtaining the heavy metal concn. from the pH value and turbidity, a judging means 5 for judging the water quality by comparing the concn. of the PCB or heavy metal with the reference value, a waste water treating line consisting of various water tanks, storage tanks and treating tanks, a pump and a switching valve, receiving the waste water in the water receiving tank, then sending the waste water to the various treating tanks to apply pH control, flocculation settling and activated-carbon treatment to attain a specified water quality and discharging the treated water and a means 6 for controlling the waste water treating line based on the results of the judging means, and the waste water treatment is controlled as the waste water contaminated with PCB and heavy metal is monitored.
摘要:
PROBLEM TO BE SOLVED: To provide an evaluation method of the contamination degree of seawater and/or the sea area bottom quality, especially a practical evaluation method of the contamination degree caused by a chemical substance. SOLUTION: Panagrellus redivivus (e.g. prochromadorella sp.I) preferably a generation cycle is synchronized, and cultured together with a sample of the seawater and/or the sea area bottom quality. If there is an abnormality in ecology of nematode and/or an abnormality in a generation cycle time, it is determined that the sample is contaminated. COPYRIGHT: (C)2006,JPO&NCIPI
