Solar energy, as an inexhaustible renewable green energy, has broad application fields and good development prospects due to its unique advantages. Solar photovoltaic power generation is a kind of many kinds of development and utilization of solar energy. It has the characteristics of no pollution, renewable, flexible and storage. With China's strong support for the development of distributed photovoltaics in recent years, it has opened a new stage of marketization of photovoltaic applications. The photovoltaic power generation system has already had practical applications in the fields of road lighting and residential construction. The water treatment industry is also suitable for the application of photovoltaic power generation systems due to its unique industry characteristics. The photovoltaic power generation system has the following advantages in the application of the water treatment industry: (1) No tall buildings around Water treatment plants are mostly located in areas where industrial enterprises are relatively concentrated and in relatively remote locations. The surrounding buildings are mostly buildings with low floor heights, such as industrial plants, which block less photovoltaic power generation systems in water treatment plants. At the same time, due to the requirements of the construction conditions of the water treatment plant itself, the height of each structure and building itself is relatively low and the layout is relatively sparse, and it is not easy to cause occlusion, so it has better lighting conditions. (2) Large roof area can be installed Due to the needs of technological processes, water treatment plants usually have large-scale buildings and structures, such as bioreactors, secondary sinks, blower rooms, etc., with large photovoltaic system installation space above such structures. In addition, most of the photovoltaic power generation systems of water treatment plants belong to the roof-type distributed photovoltaic system, which does not involve new land, does not change land use, does not affect cultural relics protection requirements, does not add building area and does not change building structure. (3) Improve the processing effect The rational arrangement and design of the photovoltaic power generation system of the water treatment plant can reduce the evaporation of pool water, increase the amount of water treatment, reduce the impact of sewage evaporation on the environment, and at the same time, reduce the wind speed above the pool, improve the local small environment, and increase The temperature of the pool water enhances the growth activity of microorganisms, improves the effect of sewage treatment, and finally achieves the purpose of improving the water treatment capacity and the overall economic benefit of the project. (4) The power consumption of the water treatment plant is large and stable The water treatment plant load includes high-power loads such as blowers and submersible sewage pumps, and also contains small-power loads such as gates, grilles, and submersible flow thrusters. The calculated power is often large. In addition, because the water volume is relatively balanced, the operation of each process equipment is relatively stable, and the load characteristics are stable, which is convenient for the design of photovoltaic power generation systems. (5) PV power can be consumed on site Due to the large power consumption of the water treatment plant and the small changes, the rational design of the photovoltaic system can make the photovoltaic power be fully applied, avoiding the waste of power in the photovoltaic system, and reducing the rate of abandoned light. (6) Good financing conditions Water treatment plants usually have long operating cycles, guaranteed operations, and stable benefits. Their spontaneous and self-use ratio is high, and their return on investment is high, thus avoiding the difficulty of financing. (7) Low maintenance cost After the completion of the photovoltaic system, its operating costs are mainly maintenance costs such as cleaning water, in addition to equipment damage caused by force majeure. The cleanliness of the effluent or reclaimed water of the sewage treatment plant can meet the cleaning needs of photovoltaic modules. At the same time, after cleaning, the water source can also be directly collected into the sewage treatment process on site, thus saving water and reducing maintenance costs.
