摘要：通过河岸渗滤技术来提高水质对公共供水有很大作用。河岸渗滤技术是一种通过在河岸侧边打井，利用用河床上的沉积物质构造及河床作为天然过滤器，从而显著降低地表水体污染物浓度的技术方法。本研究的目的是为了分析巴西伯南布哥州的贝贝里比河中河岸渗滤技术对于改善水质的作用。在一个试验点，构造了一个包括一个生产井和七个观测井的物理模型。通过观测在贝贝里比河和生产井的地下水位和物理化学指标变化来评估河岸渗滤技术的效率。同时，还对大肠杆菌和蓝藻细菌的迁移进行了分析。从物理化学和细菌学的角度，河岸渗滤技术在贝贝里比河能有效地改善水质，水质能够符合巴西法律和世界卫生组织对饮用水水质的要求。

Abstract: Use of bank filtration (BF) to improve water quality is of great importance for public water supply. The BF technique consists of the use of wells situated near riverbanks with sediment materials from the banks and bed as a natural filter, which significantly reduces pollutant concentration found in surface water. The objective of this study was to analyse the ability of the BF technique to improve water quality in a study performed on the Beberibe River, Pernambuco State, Brazil. At a pilot scale, physical structure in the experimental module comprises one production well and seven observation wells. Groundwater levels and physical–chemical monitoring were conducted both at the Beberibe River and a production well, to evaluate the effectiveness of the BF technique. In addition, coliforms group and cyanobacteria removal were also analysed. The BF technique at the Beberibe River effectively improved water quality in terms of physical–chemical and bacteriological parameters and pumped water complies with potability standards required by Brazilian law and the rules of the World Health Organization.
