- 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.
