wherein V represents the flow value of the sewage flowing through the sewage inlet pipe measured by the flow sensor; r represents the radius of the sewage inlet pipe; g represents the gravitational acceleration; p1A pressure value representing an outlet of the sewage inlet pipe; p2A pressure value representing an inlet of the sewage inlet pipe; l represents the length of the sewage inlet pipe; t represents the time from the beginning to the end of the sewage flowing through the sewage inlet pipe; the value range of the sensitivity factor of the probe of the flow sensor is [0.7,1]；
Meanwhile, calculating the sedimentation rate of the sewage in the sedimentation tank body (1) according to the following formula and based on the flow value V:
wherein K represents the precipitation rate; λ represents an impurity coefficient; represents the upper limit of the total number of impurity particles; beta represents the variable of impurity particles in the sedimentation tank body (1); q represents the standard precipitation rate of impurity particles; v represents the volume of sewage in the sedimentation tank;
comparing the obtained precipitation rate with a reference rate, and if the precipitation rate is greater than or equal to the reference rate, judging that the impurity precipitation in the sewage is qualified;
at the moment, the sewage outlets (3) on two sides of the bottom end of the outer part of the sedimentation tank body (1) are opened, and the second alarm is controlled to carry out third alarm reminding based on the second controller;
otherwise, the second alarm is controlled to carry out fourth alarm reminding directly based on the second controller;
and when the flow sensor detects that the sedimentation tank body (1) is full of sewage, the second controller is communicated with the alarm to carry out fifth alarm reminding, and meanwhile, the second controller controls the electric valve at the sewage inlet to be closed.
