Second Songhua River Pollutant Carrying Capability And Limitations Emissions Study

The songhuajiang river basin in china's northeast, the total area of about 73.4 thousand km2, except for a 540.8 km2 of liaoning, jilin province in china. The songhuajiang is the songhuajiang river to nanyuan, the changbai mountain peak of mountain and river 958km live in length.Northeast old industrial base is gradually implementing the strategy for revitalizing northeast region, social and economic development has walked fast, use water to demand, increasing the songhuajiang river basin of water pollution situation is serious; At the same time, the northeast old industrial base of the water quality of water, water supply and security of the ecological environment to increased protection. basin of water resources are facing new opportunities and challenges. faced with the new situation.Based on the Second Songhua River pollution sources and water quality investigation and assessment, selected for the second Songhua River pollutant carrying capacity of the computing model, Water function zoning for the unit, refer to the water quality objectives, determining the calculation parameters, calculation of the second Songhua River pollutant carrying capacity.Combined with the principles of the national total emissions of the restriction, the actual situation of the Second Songhua River, a second limit emissions Songhua River. Status determined based on the amount into the river cuts the second volume of the Songhua River Basin and to analyze the focus of the second reduction in the Songhua River Basin area.This water pollutant carrying capacity identified, limiting total emissions reductions for the views and the water administration departments according to law, the effective protection of water resources, environmental protection competent department of water pollution control planning, improve the quality of surface water environment provides the basis basis and technical reference on natural health rivers requirements of socio-economic sustainable development of watershed protection is important.
