Line, apparatus and method.

The type and amount of pollutants emitted by the development of the industry is increasing year by year, and advanced treatment processes are being developed to treat them.

However, due to lack of interest in the environment, carelessness and poor management technology, pollutants that are difficult to identify even are being discharged to the water supply, and preventive studies to cope with sudden pollution accidents are not progressing properly. It is a situation and introduces expensive advanced water quality measuring instruments, but the ability to cope with unspecified contaminants is very inferior to the complexity of the expensive equipment.

Therefore, in order to solve this problem, water quality monitoring apparatuses using fish are utilized as a means of determining whether toxic substances are mixed in inflow raw water or influent sewage in a sewage treatment plant.

Japanese Unexamined Patent Publication No. 3-163358, which is one of such water quality monitoring systems, includes a breeding tank for passing a test subject, fish bred in the breeding tank, and image information of the fish into electrical signals.
