Step (10), in the step (9), the specific process that the oil-water separation tank 2 discharges the sewage into the purification tank 9 and the purification tank 9 discharges the purified water to the outside is as follows:

step1, when the amount of water in the purification tank 9 is equal to or more than the rated amount, the air bag 59 is pressed by the purification tank 9 and transmits a part of the air pressure to the air-operated valve 58, so that the air-operated valve 58 is kept 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 purification pool 9 are synchronously and intermittently lighted, when the voltage drop on the branch circuit in which all the photoresistors 50 are connected in series is at a specified value or below, the second electromagnetic valve 46 is opened, and the electromagnet 68 inside the linkage valve 60 is supplied with direct current with a specified magnitude, so that the linkage valve 60 cuts off the passage inside the air duct 64.

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

Step4, when the amount of water in the purification tank 9 decreases below the rated amount, the air pressure difference between the two ends of the linkage valve 60 inside the air duct 64 increases until the second pneumatic switch 79 is opened, and the first pneumatic switch 88 is closed by the change of the second pneumatic switch 79, so that the second solenoid valve 46 is isolated from the circuit, so that the second solenoid valve 46 is closed and the linkage valve 60 is opened.

Step5, immediately after Step4, the amount of water in the purification tank 9 drops below the rated amount, and at this time, the air bag 59 supplies insufficient power to the air-operated valve 58 to resist the difference in level between the oil-water separation tank 2 and the purification tank 9, that is, the air-operated valve 58 is in an open state, and the sewage in the oil-water separation tank 2 enters the purification tank 9.

Step6, in which the amount of water in the purification tank 9 is gradually increased, the power supplied to the air-operated valve 58 by the air bag 59 is gradually increased, that is, the opening degree of the air-operated valve 58 is gradually decreased, and when the amount of water in the purification tank 9 reaches a rated amount, the air-operated valve 58 is completely closed, so that the purification tank 9 can be quickly and accurately replenished with a specified amount of sewage (from the oil-water separation tank 2); in addition, during the daily operation, the pneumatic valve 58 can keep the water amount in the purification tank 9 at a specified value under the action of the air bag 59 (in cooperation with the action of the liquid level difference between the oil-water separation tank 2 and the purification tank 9 and the action of the anti-overflow assembly).

It should be 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 purification tank 9 increases, and at this time, the second electromagnetic valve 46 and the pneumatic valve 58 are both in a closed state, so that the water overflowing from the purification tank 9 is buffered into the water storage tank 73 through the overflow pipe 48, when the water in the water storage tank 73 is full, the water pump 75 is started to completely pump the water in the water storage tank 73 into the oil-water separation tank 2 for buffering, wherein the starting and the closing of the water pump 75 are determined according to the two liquid level sensors 76 in the water storage tank 73.

Step (12), in above-mentioned step (9), the constant temperature subassembly will be in operating condition always to guarantee that the temperature of water in the purifying tank 9 is more than or equal to appointed temperature always, thereby let the aquatic plant in the purifying tank 9 can not receive the influence of season temperature and reduce the purification ability, its specific process is:

s1, when the temperature of the heat conducting rod 53 is higher than or equal to the designated temperature, the temperature memory alloy conductor 56 is not contacted with the conducting wire 55, so that the heat conducting rod 53 is disconnected from the direct current voltage stabilizing source 77.

S2, when the temperature of the heat conducting rod 53 is lower than the designated temperature, the temperature memory alloy conductor 56 is in contact with the conducting wire 55, so that the heat conducting rod 53 is connected with the direct current voltage stabilizing source 77, the heat conducting rod 53 is heated, and the water in the purification tank 9 is heated.

It should be noted that, in order to further reduce the consumption of the thermostatic assembly on the electric energy, in practical applications, a thermal sensitive color-changing coating may be provided on the surface of the heat conducting rod 53, and the color of the thermal sensitive color-changing coating gradually changes from black to light with the increase of the temperature, so that the heat conducting rod 53 can absorb the heat energy of the sun through the thermal sensitive color-changing coating to heat the water in the purifying tank 9.

And (13) while the steps (1) to (12) are carried out, 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 parts.
