ZHANG Yan, YAN Bai-xing. Research on Influence of Ditch Sediments Purifying Nitrogen from Water under Drying and Wetting Conditions[J]. 2011, 25(3).DOI:
In order to discuss the effects of drying and wetting conditions on the capability of ditch sediments purifying nitrogen
different drying and wetting conditions of the simulation tests were performed to study the purification capacity of sediments.The results showed that the purification efficiency of ditch sediments was improved with drying time increasing.At the same time
the concentration of nitrate reached to the peak and then decreased.Finally
the removal rate of total nitrogen under conditions of cont...
