Water Quality Simulation of 4-Nitrochlorobenzene in the Middle Yellow River

A simulation study of 4-nitrochlorobenzene(P-NCCB) for Transport and transformation in the Middle Yellow River has been formulated.The paper focuses attention on effect of suspended sediments to transport and fate of 4-nitrochlorbenzene.The methods of calibration and verification of the models were studied.The simulation results of different type for flow periods, suspended sediments content and sedimentation were obtained.The models consist of water hydrodynamic DOC deoxygenation, and water quality models for description of partition, photolysis and volatilization of P-NCB.
