潮汐影响下的电厂温排放实验研究

朝汐河口的冷却水工程由于受潮汐影响，其布置及热污染较为复杂。本文根据冷却水物理模型试验相似条件。对福建省宁德电厂一、二期取排水工程冷却水物理模型进行了设计。详细介绍了对各种水文务件下的温差水流实验。测得表层温度分布场和取水口取水温升。结果表明，该模型较好地复演了原体水流漉态。为减轻温排水相互影响程度及对环境影响的评价提供了科学的依据。并为各期循环水取排水工程安全、可靠、经济的运行提供了保证。

Heated Discharge Test of Ningde Power Plant in Tidal River

The characteristics of cooling water and its thermal pollution in tidal river are very complex. This paper introduces the design for the cooling water model of water supply and drainage project in first and second stage, according to the similar criteria of physical model, and temperature difference test under the different hydrology, which surface temperature field and excess intake temperature were measured. The result shows that the model not only duplicate prototype flow state well, but also offers scientific evidence to EIA and relief the extent of mutual influence of heated discharge, and provides secure for the safety of cycling water projects of every stage, trustiness of and economy of.
