Characteristics of Ammonia Nitrogen and Nitrite Nitrogen Removal with GAC-Sand Dual Media Filter Processes
摘要
Abstract
GAC-sand dual media filter was used as rapid filter during drinking water treatment. Ammonia nitrogen and nitrite nitrogen removal characteristics were studied. Three bench -scale GAC -sand filters were operated for a year, and the performance shows that GAC-Sand filters can remove ammonia nitrogen and nitrite nitrogen stably and effectively. Ammonia nitrogen is below 0.1 mg/L and nitrite nitrogen are not detected in the fdter effluent for most of time, which is better than the sand fdters in the drinking water treatment plant. Removal efficiency is decreased when filtration velocity increases. Temperature and backwashing have little impact on ammonia nitrogen and nitrite nitrogen removal, while the removal efficiency increases along the filter depth under higher temperatures or after backwashing.关键词
