In the step (9), the specific process of the oil-water separation tank 2 discharging the sewage into the purification tank 9 and the purification tank 9 discharging the purified water to the outside is as follows:

step1, when the amount of water in the purge tank 9 is at or above a predetermined amount, the air bag 59 is pressed by the purge tank 9 and transmits a part of the air pressure to the air-operated valve 58, thereby maintaining the air-operated valve 58 in a closed state, and at this time, the second electromagnetic valve 46 is also in a closed state.

Step2, all the laser sources 51 in the purge tank 9 are turned on synchronously and intermittently, when the voltage drop on the branch of all the photoresistors 50 connected in series is at or below a specified value, the second solenoid valve 46 is opened, and the electromagnet 68 inside the linkage valve 60 is supplied with a direct current of a specified magnitude, so that the linkage valve 60 blocks the passage inside the air duct 64.

Step3, the amount of water in the purge tank 9 is continuously reduced.

Step4, when the amount of water in the purifying tank 9 decreases below the rated amount, the air pressure difference inside the air duct 64 at both ends of the linkage valve 60 becomes larger and larger until the second pneumatic switch 79 is turned off, and simultaneously the first pneumatic switch 88 is turned on by the change of the second pneumatic switch 79, thereby isolating the second solenoid valve 46 from the circuit, so that the second solenoid valve 46 is closed, and the linkage valve 60 is opened.

Step5, immediately after Step4, the water amount in the purifying tank 9 drops below a rated amount, and at this time, the power provided by the air bag 59 to the air-operated valve 58 is insufficient to resist the liquid level difference between the oil-water separation tank 2 and the purifying tank 9, i.e. the air-operated valve 58 is in an open state, and the sewage in the oil-water separation tank 2 enters the purifying tank 9.

Step6, in Step5, the water amount in the purifying tank 9 is gradually increased, the power provided by the air bag 59 to the air-operated valve 58 is gradually increased, that is, the opening degree of the air-operated valve 58 is gradually decreased, and when the water amount in the purifying tank 9 reaches a rated amount, the air-operated valve 58 is completely closed, so that the purifying tank 9 can rapidly and accurately supplement a specified amount of sewage (from the oil-water separation tank 2); in addition, during daily operation, the pneumatic valve 58 can always keep the water amount in the purifying tank 9 at a specified value under the action of the air bag 59 (in combination with the action of the liquid level difference in the oil-water separating tank 2 and the purifying tank 9 and the action of the overflow preventing assembly).

It is noted that the operation of the first pneumatic switch 88, the second pneumatic switch 79, the electromagnet 68 and the second solenoid valve 46 is specifically shown in fig. 3.

Step7, when rain and snow occur, the water amount in the purifying tank 9 is increased, and at the moment, the second electromagnetic valve 46 and the pneumatic valve 58 are both in a closed state, so that overflowed water in the purifying tank 9 is buffered in the water storage tank 73 through the overflow pipe 48, when the water storage tank 73 is full of water, the water suction pump 75 is started to completely suck the water amount in the water storage tank 73 into the oil-water separation tank 2 for buffering, and the starting and the closing of the water suction pump 75 are judged according to two liquid level sensors 76 in the water storage tank 73.

And step (11), in the step (9), the mixed flow component in the purifying tank 9 is always in a working state, so that the water in the purifying tank 9 is ensured to be in a flowing state, the purifying dead angle in the purifying tank 9 is avoided, and meanwhile, the purifying efficiency of the purifying tank 9 is improved.

Step (12), in the step (9), the constant temperature assembly is always in a working state, so as to ensure that the water temperature in the purifying tank 9 is always equal to or higher than a specified temperature, thereby enabling the aquatic plants in the purifying tank 9 to be free from the influence of the seasonal temperature and reducing the purifying capacity, and the specific process is as follows:

S1, when the temperature of the heat conduction rod 53 is equal to or higher than the specified temperature, the temperature memory alloy conductor 56 is not in contact with the wire 55, so that the disconnection between the heat conduction rod 53 and the direct-current voltage-stabilizing source 77 is made.

S2, when the temperature of the heat conduction rod 53 is less than the specified temperature, the temperature memory alloy conductor 56 is in contact with the wire 55, so that the connection between the heat conduction rod 53 and the direct current voltage stabilizing source 77 is made, so that the heat conduction rod 53 generates heat, and the water of the purifying tank 9 is heated.

It should be noted that, in order to further reduce the consumption of electric energy by the constant temperature assembly, in practical application, a thermally induced color-changing coating may be disposed on the surface of the heat conducting rod 53, where the color of the thermally induced color-changing coating gradually changes from black to light with the temperature rise, so that the heat conducting rod 53 can absorb the heat energy of the sun through the thermally induced color-changing coating to heat the water in the purifying tank 9.

And (13) while the steps (1) to (12) are performed, the photovoltaic module is always in a working state, the collected solar energy is converted into electric energy to be stored in the storage battery 87, and then the storage battery 87 supplies power to all the electric components.
