摘要:
滨州市农村供水中心相周水厂的原水硝酸根离子出现季节性超标，而现有处理工艺无法在超标期间向周围居民提供安全饮用水。为降低水中硝酸盐的污染，利用水厂现有构筑物，采用投加结构重构树脂的工艺改造方案，可以很好地去除原水中的硝酸根离子，出水硝酸根浓度可以控制在10 mg/L以下。该方案无需增设额外处理设施，适用于占地面积小、资金短缺等情况下对水质的应急处理，可为各类水厂的应急改造提供参考。
Abstract:
When the nitrate ion in the raw water of Xiangzhou rural water supply center in Binzhou City exceeded the standard seasonally, the waterworks cannot provide safe drinking water to the surrounding residents by the existing treatment process. In order to reduce the pollution of nitrate in water, the existing structures in the waterworks were employed to reconstruct the process by adding structural reconstruction resin. Thus, the nitrate ion in raw water can be removed well, and the effluent concentration of nitrate can be controlled below 10 mg/L. The process requires no additional treatment facilities, and is adaptable to the emergency treatment of water quality in waterworks under the condition of small footprint and funds shortage, which provides a reference for the emergency reconstruction of all kinds of waterworks.
