本文报导了对拟建巢湖电厂前水域水生生物调查和预测电厂建成后温排水对该水域环境的影响。经实验表明,拟建电厂的温排水对温升区内的水环境会带来一定影响。春末、初秋水温升高,会促使微囊藻Microcystis提早滋生,大量繁殖;盛夏高温季节水温超过34℃时,对微囊藻生长不利,甚至引起死亡。但因拟建电厂的温排水等温线,在最不利的条件下,3℃升温区的面积为1.02~2.03km2,仅占全湖面积的1.33~2.26‰,对巢湖水环境影响不大。
This article reports on the investigation of the aquatic organisms in the pre-constructed Chaohu Power Plant and the prediction of the impact of the temperature and temperature on the environment after the completion of the power plant. The experiment shows that the proposed thermal drainage of power plants will bring a certain impact on the water environment within the temperature rise area. In late spring and early autumn, the increase of water temperature will cause Microcystis to breed prematurely and multiply in large quantities. When the water temperature exceeds 34 ℃ in midsummer, the growth of Microcystis will be unfavorable and even cause death. However, due to the proposed thermal drainage isotherms, under the most unfavorable conditions, the area of 3 ℃ heating zone is 1.02 ~ 2.03km2, accounting for only 1.33 ~ 2.26 ‰ of the entire lake area, Water environment has little effect.
