Study on Characteristics in the Removal Process of Ammonia Nitrogen and Nitrate Nitrogen by an Isolated Heterotrophic Nitrification-Aerobic Denitrification Strain Rhodococcus Sp.
Aerobic denitrification Heterotrophic nitrification Rhodococcus sp Nitrogen removal
2013/3/9
Removal of ammonia nitrogen and nitrate nitrogen by an heterotrophic nitrification-aerobic denitrification strain is an economical and effective method. In this article, a kind of heterotrophic nitrif...
Effect of Different Nitrogen Fertilizer Types and Application Measures on Temporal and Spatial Variation of Soil Nitrate-Nitrogen at Cucumber Field
Solar Greenhouse Cucumber Nitrate-Nitrogen Nitrogen Retention
2013/3/8
Nitrate-nitrogen content of groundwater are ever-increasing in underneath vegetable growing areas, in this paper, based on field test of cucumber cultivated in Solar Greenhouse in North China, we stud...
Does Exposure to Nitrate in Drinking Water Contribute Anything the Effect of Water Chlorination on Children Methemoglobin Levels?
Methemoglobin Drinking Water Nitrate Chlorine Children
2013/3/11
Previous studies showed contradictory findings regarding the relationship between nitrate in drinking well-water and abnormal methemoglobin (MetHb) level (>2%) among children. We studied the effect of...

Soil aquifer treatment Wastewater Nitrite and nitrate removal
2009/10/10
Bench-scale soil column experiments were performed to examine the e ects of soil type and in ltration conditions on the removal eciencies of wastewater nitrites and nitrates during the biological rip...
Nitrate removal in stream ecosystems measured by 15N addition experiments: Denitrification
Nitrate removal stream ecosystems measured 15N addition experiments Denitrification
2014/4/18
We measured denitrification rates using a field 15NO3- tracer-addition approach in a large, cross-site study of nitrate uptake in reference, agricultural, and suburban-urban streams. We measured denit...
Nitrate removal in stream ecosystems measured by 15N addition experiments: Total uptake
Nitrate removal stream ecosystems measured 15N addition experiments Total uptake
2014/4/18
We measured uptake length of 15NO3- in 72 streams in eight regions across the United States and Puerto Rico to develop quantitative predictive models on controls of NO3- uptake length. As part of the ...
