The Water Environmental Capacity In Mudanjiang City Measure Of Research And Its Development Trend

Along with the rapid development of industries in mudanjiang city, mudanjiang city water supply and demand of water pollution and increasingly prominent contradiction. Faced with the severe water environment pollution problems in mudanjiang, it not only adversely affect the economic development, but also for the serious threat to human survival, which prompted us to reassess the environmental problems.From the water environmental capacity utilization and management perspective, the water environmental quality in scientific evaluation based on the status quo of water environment, according to the water quality objectives, through the area pollution sources and pollutants and the classification of water pollution, establish the water environmental quality - the input response relationship in the water environmental capacity is approved, based on the water environment, the function of pollutants from water, allowing emissions into the valley area environment water environmental capacity utilization, protection and distribution, to ensure that the water environment of the function of water environment, environmental capacity to provide scientific basis for the quantitative management and technical platform.Based on the surface water environment in mudanjiang city functional capacity calculation, various water environment function of water environmental capacity, the main pollution sources of sewage and waste allowed. Results show that the water environmental capacity, has no capacity in some river of mudanjiang,the capacity of COD should fully satisfy mudanjiang city development needs in 2010, but due to the market, we need to strengthen the poor quality of NH4+-N, COD of total amount control, namely in the road - five kilometers of the enterprise, reducing the total river, five kilometers, the enterprise proper chain river, can satisfy total control objectives.Based on the author's own practice, according to the results of the calculation, the total amount control and reduction plan and accord with the characteristics of water environment in mudanjiang city management solutions, after that the environment management and decision-making more scientific, reasonable and to study the sustainable development of water environment in mudanjiang city has important practical value and significance.
