Heze Power Plant, a developing national large-scale power generation enterprise, now has an installed capacity of 850WM, of which, the first phase of the installation of 2 × 125MW coal-fired generating units, with a total investment of 706 million yuan. The second phase of the installation of 2 × 300MW coal-fired units, is the first time in Shandong Province, using imported W flame furnace, the total project investment of 3.511 billion yuan. The plant has 1713 employees, including 59.07% of the total number of employees with secondary education or above. Thermal power plant is both "coal tiger" and "big buffalo", in the current severe situation of bidding for Internet access, especially in northern China, water scarcity has gradually become a bottleneck in the development of electric power, how to open up new sources of income and cut down on expenditure, seek new water resources, improve water utilization rate is an urgent solution for thermal power plants. It is an urgent problem for thermal power plants to solve. Carrying out urban water reuse is one of the important ways to solve this problem, but also the general trend. City water is large and stable, after deep treatment, as a thermal power plant circulating cooling water replenishment source is practicable, not only reflects the energy saving and emission reduction, cleaner production of the ideological approach, but also in line with the development of a circular economy, the construction of a resource-saving society, while expanding the space for the sustainable development of the electric power industry, has an important economic, social and environmental benefits.
Heze power plant is a major energy consumer, a year to burn off 3.7 million tons of coal, but also a major consumer of water resources, a year to evaporate 20 million tons of water. Not far from the power plant in Heze City sewage treatment plant, since the operation of tens of thousands of dollars a day to deal with urban sewage, after which it is discharged into the river for nothing. In order to improve the efficiency of water utilization, Heze Runze Renewable Water Co., Ltd. has signed an agreement on water utilization with two Heze power plants. At present, Heze Runze Renewable Water Conservancy Co., Ltd. delivers about 10,000 tons of water to Heze Power Plant every day.
Heze Power Plant, Heze City sewage treatment plant, Heze City Environmental Protection Bureau, three units, each calculated a "happy account": Heze Power Plant through the water reuse project to solve the problem of water shortages in the three phases of the project, the Heze City sewage treatment plant through the sale of water to the Heze Power Plant, a year of more than 5 million yuan in revenue, to make up for the lack of funds for sewage treatment. Make up for the problem of insufficient funds for sewage treatment, the implementation of water reuse project, so that Heze can reduce COD emissions by 70 tons per year.
At present, heze power plant three projects use water, two thirds from twenty kilometers away from the yellow river, and one third from the power plant is located in heze runze reclaimed water limited company to deal with good water. In the future, when the conditions are ripe, all the water used in the three phases of the Heze Power Plant will be changed to water. This not only saves costs, but also makes its own contribution to reducing pollution emissions.
