The invention discloses a cross-basin water transfer and energy storage system and a water transfer and energy storage method, particularly relates to various major basins and main power grids, and belongs to the field of the water resource and energy storage. The disclosed cross-basin water transfer and energy storage system is a multi-level system formed and constructed through various cross-basin water ways and water transfer and energy storage power stations according to the provided water transfer and energy storage technical method; and by means of the cross-basin water transfer and energy storage system, water resource allocation of various area scales can be achieved, and meanwhile corresponding water power energy storage systems can be established. According to the disclosed cross-basin water transfer and energy storage system embodiment, the purposes and the application are not limited in establishing of a cross-basin river and lake major cycle and the water transfer and energy storage power stations at the corresponding nodes, macroscopic overall water resource allocation can be achieved, meanwhile, grid-connection regulation and control are conducted on the state grid corporation of China and the China southern power grid, and in other words, river and lake energy storage and water power generation can be achieved; and the problems about water resource supply and demand contradiction and development and utilization and the problems about electric power supply and demand contradiction and energy abandoning are effectively solved.

The invention relates to the technical field of sewage treatment, and discloses a novel sewage treatment device, comprising a storage barrel, buffer cylinders are arranged at the four corners of the bottom of the storage barrel, buffer plates are arranged inside the buffer cylinder, and the buffer plate The top of the buffer rod is fixedly connected with a buffer rod, the top of the buffer rod penetrates and extends to the top of the buffer cylinder, the top of the buffer rod is fixedly connected with the storage barrel, the bottom of the buffer plate is provided with a buffer spring, and the storage barrel A protective box is arranged on the top of the protective box, and a drive motor is fixedly connected to the inner top wall of the protective box. In this invention, the water in the storage tank can be transferred to the reaction tank through the work of the pressurized pump, and the transferred water can be adsorbed and removed by the activated carbon adsorption plate, and then the air can be injected into the reaction tank through the work of the aeration pump. The reaction barrel is convenient to speed up the reaction speed of the biofilm reaction component, and it is easier to remove impurities and can remove impurities more cleanly.

A power supply ECU is configured to: adjust magnitude of transmission power by adjusting a duty of an output voltage of an inverter; and adjust a frequency of the transmission power by controlling the inverter. The power supply ECU is configured to execute first control and second control. In the first control, the frequency is adjusted such that a loss of the inverter decreases while maintaining the transmission power, when a temperature of the inverter exceeds a limit temperature. In the second control, the transmission power is reduced, when the temperature of the inverter exceeds the limit temperature even if the first control is executed.
