摘要： 经排查分析，得出了汽动给水泵轴封回水管和轴加疏水管排入位置选择不当是造成凝结水溶氧量超标的主要原因，
并对现场处理措施进行了探讨。通过采用科学有效的措施，凝结水溶氧量由超标变为优良状态，取得了良好的实际效果。

Abstract: After investigation and analysis, this paper obtained that the improper selection of the discharge position of the shaft
seal return pipe and the shaft plus drain pipe of the steam-driven feedwater pump was the main reason for the excessive dissolved
oxygen content in the condensed water, and discussed the on-site treatment measures. By adopting scientific and effective measures,
the dissolved oxygen content in the condensed water has changed from exceeding the standard to a good state, and good practical
results have been achieved.

Key words: ultra-supercritical unit; condensed water; dissolved oxygen
