峡口水闸扩建工程环境风险评价

Environmental Risk Assessment of Xiakou Sluice Expansion Project

峡口水闸外江上分布有一级饮用水源保护区及众多取水口,峡口水闸需扩建4孔水闸及新建船闸,工程建设、运营可能存在水环境风险,影响附近水源保护区及取水口水质。本文通过分析与预测,提出了最大风险事故,确定了典型工况下风险事故发生时对水源保护区的影响及对水厂的响应时间,以期为该河道管理提供参考。

There is a first-grade drinking water source protection area and many water intakes on the outer river of Xiakou Sluice, Xiakou Sluice needs to expand 4 hole sluice and new ship lock. There may be water environmental risks in the construction and operation of the project, affecting the water quality of nearby water source protection areas and water intakes. Through analysis and prediction, this paper proposes the most risk accident, determines the impact on the water source protection area and the response time to the water plant when the risk accident occurs under typical conditions, in order to provide reference for the river management.
