风光互补电站在工业废水处理中的效益分析

Benefit analysis of wind-solar hybrid power station in industrial wastewater treatment

以内蒙古鄂尔多斯某工业园区废水处理项目为例,分析预测风光互补电站在工业废水处理中的应用前景。结果显示:项目投资将增加23%,电站预计平均年发电量为918.3万kWh,寿命期内节省总费用约5 819.4万元,平均每年节省电费194.0万元,电耗节省0.51元/吨水;预计可以减少使用标准煤约3 058 t/a,减排CO_(2)约5 293~9 008 t/a,减排SO_(2)约26.9 t/a,减排氮氧化物约23.5 t/a,减排烟尘约177.2 t/a,环境成本节省约381.1万元/a,折合1.01元/吨水,具有较好的经济效益和显著的环境效益。

Taking an industrial park wastewater treatment project in Ordos, Inner Mongolia as an example, the application prospect of wind-solar hybrid power station in industrial wastewater treatment is analyzed and predicted. The results show that, the investment of the project will increase by 23%. The average annual power generation of the power station is estimated to be 9.183 million kWh. The total cost to be saved during the service life is about 58.194 million yuan, with an average annual saving of 1.94 million yuan and 0.51 yuan per ton of water in electricity. It is estimated that 3 058 tons of standard coal, 5 293~9 008 t/a of CO_(2), 26.9 t/a of SO_(2), 23.5 t/a of NO_(x) and 177.2 t/a of dust will be reduced.The environmental cost will be saved about 3.811 million yuan per year, equivalent to 1.01 yuan per ton of water, which will have good economic benefits and very significant environmental benefits.
