Precipitation and inactivation of phosphorus(P) by the addition of aluminum (AI) is a widely applied sediment restoration measure. Laboratory experiment with sediment from municipal river was conducted to evaluate the effects of poly-aluminum chloride with different adding means. Adding poly-aluminum chloride doesn't remarkably influence pH. At the same time Al3+ concentration is less than 50 ug·L...
The application of nitrate is an accepted procedure to manage eutrophication municipal rivers by controlling the phosphorus release from sediments into overlying water and offering electron acceptor for microorganism metabolism. An in-situ-experiment was carried out to oxidize the sediment by direct calcium nitrate injection. Phosphorus release from sediment injected calcium nitrate was almost stopped...
It is well known that no uniform prediction approaches were obtained regarding ground water level, though the neural network and some other so-called artificial intelligence methods consistently provide the smallest uncertainty and different medians warranting further research on their abilities. In the present paper, the lower reaches of Tarim River is taken as the study area, a grey correlation...
