Abstract

It is very important to accurately predict the river water quality. Prediction of river water quality has been closely watched in water resources evaluation, and is the primary work of scientific planning and management of water resources and exploitation. The accuracy of prediction will directly influence whether we can work out a reasonable plan and management measures. According to the relationship of river water quality with the influencing factors, regression method is used to predict the tendency of river water quality. The influencing factors include rainfall, sediment and runoff. This study could provide reference and guidance for further exploitation of river water.

Abstract

Based on the previous research, the experiment of ammonia nitrogen degradation in water with sediment has been set-up. The sample of sediment was selected from Zhang river. The degradation regularity of ammonia nitrogen in water with sediment was studied systematically. Under the different parameters as sediment concentration, sediment size and different initial concentrations of ammonia nitrogen, a series of experiments on the degradation of ammonia nitrogen in water with sediment were carried out. First-order kinetics was adopted to fit the experimental results, and the influences of the sediment concentration and the particle size on the reaction rate are discussed. The research shows that the degradation process of ammonia nitrogen and organisms both are conformed to the first-order kinetics and the higher the sediment concentration and smaller the particle size are, the greater is the reaction rate constant.
