20%~30% is reduced in object prewarning unit, then illustrates that water pollution occurs, by the average travelling speed in biotic warning unit
Degree, average number of turns, the mean activity depth of water and it is total hit the frequency react with established Fish behavior-degree of water pollution is black
Box model compares, and quantitative identification goes out the degree of water pollution, and is alarmed by display unit and alarm unit.
8. the method for early warning of the water pollution monitoring prior-warning device according to claim 5 based on Fish behavior, feature exist
In: in step (3), Fish behavior reaction-degree of water pollution black-box model method for building up are as follows: setting experimental group and control
Group, experimental group and control group are the identical self-contained water tank structure of experiment condition, and inside contains the cleaning water source of equivalent respectively；
Specific pollutant is added into the cleaning water source of experimental group, the behavior of observation experiment group water body Mesichthyes gradually promotes water body
Middle pollutant concentration, experiment with computing group Mesichthyes abnormal behaviour monitors functional value, to construct fish abnormal behaviour and the pollution
Corresponding relationship between object concentration；Repeat to test for different pollutants, establishes Fish behavior reaction-water pollution journey
Spend black-box model.
9. the method for early warning of the water pollution monitoring prior-warning device according to claim 6 based on Fish behavior, feature exist
In: the experiment condition of check experiment group is identical with experiment reaction chamber with reaction box sizes, and check experiment group reacts cabinet
Introducing is cleaning water source.
10. the water pollution monitoring prior-warning device according to claim 8 based on Fish behavior, it is characterised in that: calculate fish
The parameter of class abnormal behaviour monitoring functional value includes: that fish averagely move about speed, average number of turns, the mean activity depth of water and total
The frequency is hit, set experimental group and each parameter of control group allow difference value to be respectively as follows: average travelling speed S difference S0=
20mm/s, average number of turns C difference C0=3 times, averagely shock frequency Q difference Q0=5 times/min, mean activity depth of water H difference
H0=0.05m；It calculates fish abnormal behaviour and monitors functional value:Wherein,Weight corresponding to respectively each parameter calculates functional value by fish monitoring data to judge water body dirt
The degree of dye if F≤1 illustrates that water pollution does not occur；If 1 F≤2 <, slight pollution occurs；If 2 F≤3 <, it is dirty that moderate occurs
Dye；If F > 3, serious pollution occurs.
