Research Of The Building Regarding Water Quality Model And Setting Emission Limits In Liao River Basin Based On MIKE

In order to improve the current situation of the Liaohe River Basin water environment, to solve the problem of water resource shortage, "Twelfth Five-Year Plan" period to carry out a "comprehensive water pollution control technology integration and demonstration project" Liaohe River Basin Project. After treatment in recent years, Liaohe River Basin water quality deterioration has been effectively controlled, But water pollution is still serious. "Twelfth Five-Year Plan" period in Liaohe river ecological protection zone of restoration of security measures and management system is one of the research tasks of Liaohe protection water ecological construction demonstration project, While the water quality simulation is a key task.The establishment is the premise of the protection zone of ecological monitoring platform and ecological management of data resources sharing platform, combined with the construction process of ecological protection zone of Liaohe Basin, on the basis of simulation can be implemented, both point sources and non-point source pollution, considering the economic and technical feasibility, using MIKE software, content of the Liao River basin hydrological fudedian to Tieling section of water quality and physical and biochemical indexes, biochemical process simulation.To prediction the pollutant diffusion in Liaohe River basin protection zone of migration, for the establishment of ecological monitoring platform and ecological management of data resources in Liaohe ecological sharing practical technology and data on the platform.The results show, one-dimensional water quality simulation fudedian to simulate water level of Tieling section of the river and flow values fit well with the measured values, illustrated by MIKE software to establish the Liaohe river hydrodynamic model is feasible. ECO Lab simulation of the simulation region under the conditions of different pollutants concentration distribution with time migration. By the results of simulation two aspects, application of MIKE 11 software simulation in the Liaohe River Basin were determined, for the prevention of pollution, Prediction of Liaohe river flow and water level changes, To advance prevention provides a good foundation.
