Abstract

The invention discloses a sewage treatment system with photovoltaic power and commercial power collaborated power supply. The sewage treatment system includes a distributed photovoltaic array, an intelligent control system, a photovoltaic energy storage system, a low-voltage power distribution system, a sewage treatment system and a photovoltaic flushing device. The intelligent control system controls transmission of the photovoltaic power generated by the distributed photovoltaic array to the low-voltage power distribution system and storage to the photovoltaic energy storage system, and commercial power is incorporated into the low-voltage power distribution system simultaneously, the intelligent control system controls the low-voltage power distribution system's supply of photovoltaic power and/or commercial power to electric equipment of the sewage treatment system, and the intelligent control system controls the photovoltaic flushing device in terms of extracting water from a clear water tank of the sewage treatment system to flush photovoltaic components. The invention also discloses a power supply method. The sewage treatment system and the method provided by the invention maximumly utilize photovoltaic power to supply power, employ the treated sewage for secondary utilization, and ensure the efficiency of photovoltaic power generation. The whole system is controlled by the intelligent control system, and has the advantages of simple operation and efficient operation.

Description

technical field [0001] The invention relates to photovoltaic power generation and sewage treatment systems, in particular to a sewage treatment system and power supply method in which distributed photovoltaic power generation and mains power supply are coordinated. Background technique [0002] Compared with commercial power, photovoltaic power generation has a simple power generation process, no mechanical rotating parts, no fuel consumption, no emission of any substances including greenhouse gases, no noise, no pollution; however, photovoltaic power generation is affected by light intensity, season, region, Influenced by external uncontrollable factors such as weather, stable electric energy cannot be continuously supplied, especially at night, the photovoltaic array will stop receiving solar radiation energy, and the regulation steps of photovoltaic power generation projects are cumbersome and complicated. During the operation of photovoltaic power generation projects, ph...
