Solar photovoltaic power generation has become one of the environmentally friendly alternative energy sources due to its significant advantages such as cleanliness, high efficiency, safety, and regeneration. Vigorously developing photovoltaic power generation can reduce the pollution caused by the combustion of fossil energy to the environment. Sewage treatment plants and water plants mainly remove pollutants such as COD and ammonia nitrogen, and electricity consumption accounts for a large proportion of direct production costs. The application of clean energy to the emission reduction of pollutants in the field of water supply and drainage will achieve emission reduction of air and water environment pollution win-win.
①Abundant land resources. The water treatment plant has a large-area water treatment tank, and the installation of solar photovoltaic panels on it has a unique space advantage, which can be used for secondary development and utilization of the land occupied by the vast water treatment plant, which can be used for intensive land use. The effect of comprehensive utilization of land.
②High energy-consuming industries. Sewage treatment plants and water plants have high electricity loads, and are large energy consumers. They operate continuously for 24 hours and have stable loads. Basically, the power generated by photovoltaic power plants can be absorbed by the electricity load of water treatment plants, which is in line with the "spontaneous self-consumption" mode. . In the direct production cost of water treatment plants, electricity consumption accounts for more than 30%, and there is a strong demand for cost reduction and efficiency improvement. The combination of photovoltaic power generation and water treatment, and the implementation of contract energy management can further reduce the cost of sewage and tap water treatment.
③ Good stability. Sewage and tap water treatment facilities are public infrastructure, with long land use life and low risk of outage. Compared with other types of urban building roofs, they have better investment stability.
④Good financing conditions. A water treatment plant is similar to a public utility, and its long-term operation is guaranteed, with a high proportion of self-consumption and self-use, high return on investment, and stable project construction income. Whether it is a bank or other investors, they will be more satisfied and can avoid financing difficulties.
⑤ The water treatment field itself needs to be stamped. Some water treatment ponds need to be covered to inhibit the growth of algae due to their technological needs. The construction of a grid above the pool surface is in line with their own needs for covering.
