The lifting system 40, the aeration system 50, the backflow system 60, the dosing system 70, the disinfection system 80 and the stirring system 90 are respectively electrically connected with the photovoltaic power generation system 20 and the utility grid system 30, and a control switch 2 is arranged on each group of connecting lines. The control switches 2 are arranged into a plurality of groups, the control switches 2 in signal connection with the control system 10 are arranged between each energy consumption system and the photovoltaic power generation system 20 and between each energy consumption system and the utility grid system 30, and the control system 10 controls the on and off of each control switch 2 so as to control the on and off of circuits between each energy consumption system and the photovoltaic power generation system 20 and between each energy consumption system and the utility grid system 30.

A liquid level sensor 1 is arranged in the regulating tank, and the illumination measuring instrument 21, the liquid level sensor 1 and the plurality of groups of control switches 2 are in signal connection with the control system 10. The illumination meter 21 can detect the current illumination intensity and transmit it to the control system 10, thereby calculating the power generation amount of the photovoltaic power generation system 20. Level sensor 1 can monitor the sewage liquid level in the equalizing basin to compare sewage liquid level with the default, thereby select lift system 40 whether to supply power as first priority, prevent that the sewage is excessive in the equalizing basin, influence normal sewage treatment work.
So set up, through dividing into each energy consumption system with the power consumption part of integration equipment in proper order. When the illumination intensity is strong enough, the photovoltaic power generation system 20 is adopted to supply power all day long. When the photovoltaic power generation system 20 is weak and the utility grid system 30 is supplying power normally, the power supply proportion of the photovoltaic power generation system 20 and the utility grid system 30 is distributed reasonably according to the power supply amount of the photovoltaic power generation system 20 and different energy consumption systems. When the photovoltaic power generation system 20 is weak and the utility grid system 30 is powered off, different power consumption system power supply orders are selected according to the liquid level height of the regulating reservoir to realize the orderly single power supply of the photovoltaic power generation system 20. The invention can provide a cooperative control mode of the photovoltaic power generation system 20 and the utility grid system 30 under different working conditions such as sufficient illumination, insufficient illumination, mains supply power failure and the like, thereby improving the operation efficiency of equipment and reducing the operation energy consumption of the equipment.
As shown in fig. 1 to 2, in some embodiments, the control system 10 includes an instruction module 11, a storage module 12, a photovoltaic power generation monitoring module 13 in signal connection with the illumination measuring instrument 21, a utility power monitoring module 14 in signal connection with the utility grid system 30, a liquid level judgment module 15 in signal connection with the liquid level sensor 1, and a switch switching module 16 in signal connection with the plurality of sets of control switches 2, respectively.
Specifically, the storage module 12 stores the standard power consumption of each energy consumption system of the lifting system 40, the aeration system 50, the reflux system 60, the dosing system 70, the disinfection system 80 and the stirring system 90, which is normally operated for one day, so as to facilitate the subsequent calling.

When the photovoltaic power generation system 20 is not enough to maintain the normal operation of any energy consumption system, all the energy consumption systems are powered by the utility grid system 30.

The single power supply mode is that when the hoisting system 40 is powered, the rest energy consumption systems are kept in a power-off state, that is, only one group of energy consumption systems are powered at the same time.
The instruction module 11 is respectively electrically connected with the liquid level judgment module 15 and the switch switching module 16, so that when the liquid level of the regulating tank exceeds the liquid level preset value, a primary power supply sequence is adopted, and when the liquid level of the regulating tank does not exceed the liquid level preset value, a secondary power supply sequence is adopted. Wherein, the power supply sequence of each energy consumption system is divided according to the importance degree of the corresponding equipment in sewage treatment. While the lifting system 40 is concerned with the change in the level of the regulating reservoir, which belongs to the most priority power supply system.

In this step, the energy consumption system includes a lift system 40, an aeration system 50, a reflux system 60, a dosing system 70, a disinfection system 80, and a stirring system 90. Under the condition of better illumination conditions in summer, the illumination intensity can meet the power consumption of all energy consumption systems. Under the condition, the whole equipment is powered by the photovoltaic power generation system 20 all day long, and the investment of the photovoltaic panel and the energy storage system can be reduced by adopting a direct power supply mode, so that the investment cost of the whole equipment is reduced.
S2, comparing the power supply quantity of the photovoltaic power generation system 20 with the standard power consumption quantity of each energy consumption system when the energy consumption systems work normally, if the photovoltaic power generation system 20 is enough to maintain the power consumption of a single energy consumption system or a plurality of (not all) energy consumption systems, adopting the photovoltaic power generation system 20 to supply power to the energy consumption systems, and adopting the commercial power grid system 30 to supply power to the rest energy consumption systems; if the photovoltaic power generation system 20 is not enough to maintain the normal operation of any energy consumption system, all the energy consumption systems are supplied with power by the utility grid system 30.
In this step, the power supply ratio of the photovoltaic power generation system 20 to the utility grid system 30 is reasonably distributed according to different energy consumption systems according to the power supply amount of the photovoltaic power generation system 20, the photovoltaic power generation system 20 can be maximally utilized to supply power, the mains supply is reduced, the utilization of renewable energy sources and the sewage treatment integrated equipment are combined in a true sense, the power supply ratio is flexible and various, and the optimal selection can be performed according to different working conditions.
And S3, adopting different power supply sequences to supply power to each group of energy consumption systems according to the liquid level information of the regulating tank.
In this step, when the liquid level of the regulating reservoir exceeds the liquid level preset value, the photovoltaic power generation system 20 sequentially performs single power supply to the lifting system 40, the aeration system 50, the backflow system 60, the dosing system 70, the disinfection system 80 and the stirring system 90. The smooth operation of the single power supply is realized by controlling the opening and closing of the corresponding control switch 2 by the control system 10. When the liquid level of the regulating tank does not exceed the liquid level preset value, the photovoltaic power generation system 20 sequentially and singly supplies power to the aeration system 50, the backflow system 60, the dosing system 70, the disinfection system 80 and the stirring system 90.
