METHOD FOR MONITORING WATER QUALITY AND A TWO-CHANNEL BIOSENSOR INSTALLATION FOR ITS IMPLEMENTATION

摘要

FIELD: water quality control. ;SUBSTANCE: essence of the invention lies in the fact that automatic continuous registration in real time of the reactions of water test objects and the passage of controlled water through tanks with test objects is carried out by means of a two-channel biosensor installation immersed in a reservoir, and the transmission is continuous, and the flow of controlled water passes at each time through both tanks with test objects under the same physical conditions, while due to the difference in the lengths of the installation channels, controlled water enters the first and second tanks with a difference in the time interval necessary for the reaction of test objects to changes in the chemical composition of the controlled water to occur, and the reactions of groups of test objects are compared with each other by calculating the difference in their parameters in a time interval equal to the difference in the time of receipt of controlled water in the first and second tanks, and when calculating the minimum difference in the parameters of the numerical characteristics of the motor activity of test objects in both tanks, it is concluded that the chemical composition of the controlled water is unchanged, and when calculating the maximum difference, the conclusion is made about the changed chemical composition of the controlled water. The two-channel biosensor installation includes a filter, a pump with an electric motor, a flow divider, two channels of the same diameter, but of different lengths, while one of the channels is connected to one, and the second to another tank of two identical tanks equipped with drainage holes distributed evenly, the total area of which for each tank is 4-6% less than the cross-sectional area of the channel, in addition, similar test objects and devices to register their reaction to changes in the conditions of the aquatic environment are placed in each tank. ;EFFECT: invention provides the possibility of rapid detection of changes in the chemical composition of the aquatic environment. ;2 cl, 1 dwg
