摘　　要：滨海电厂运行过程中,在冷却水排水流路如虹吸井、排水渠道、排水口等,往往出现大量聚集性泡沫体,形成泡沫污染。冷却水排水泡沫污染一直是困扰滨海火核电厂的难题,传统的化学消泡剂治理方案不仅费用巨大,而且还造成潜在二次污染风险。为此,以某滨海电厂为例,在不改变排水设计要求前提下,探索采用工程措施治理电厂排水泡沫的技术方案。研究采用物理模型试验方法,模拟还原电厂排水流路的跌流掺气过程,探索并构造适应外海大变幅水位情况的永久性抑泡工程措施,为电厂排水抑泡设计提供支撑;研究方法和研究成果可为滨海电厂排水抑泡研究提供借鉴。In coastal power plants,a large number of aggregated foam bodies occur in cooling water drainage system,such as suction wells,drainage channels and drainage outlets,forming foam pollution which has always been a difficult problem.The traditional chemical defoamer treatment scheme not only is expensive,but also causes potential secondary pollution risks.In this study,taking a coastal power plant as an example,we explore the technical scheme of using engineering measures to control drainage foaming,without changing the drainage design requirements.The physical model test method was used to simulate the drop aeration process of the drainage channel of the power plant,and the permanent foam suppression engineering measures were explored and constructed to adapt to the large variation of water level in the offshore.The research method and the anti-foaming project scheme provide a reference for the study of anti-foaming in the drainage of coastal power plants.
