Method for computing river environmental capacity based on interval number theory

Abstract

The invention relates to the field of environmental management such as pollutants discharge reduction, total emission control of pollutants and the like, and discloses a method for computing a river environmental capacity based on an interval number theory aiming at the defect of the current method for computing the river environmental capacity on the aspect of considering the uncertainty. The method comprises the following three steps of firstly, collecting and researching river hydrological parameters and parameters of water quality models, combining a field test, and determining the change range of the river hydrological parameters and the parameters of water quality models; secondly, utilizing the interval number theory to establish a computation model of the river environmental capacity based on the interval number theory; and finally, on the basis of river control unit division, computing to obtain the river environmental capacity interval according to the computing rule of interval numbers. Compared with the traditional method for computing the water environmental capacity, the method is scientific, simple and practical and has the characteristics that the uncertainty of a water environmental system is fully considered, the range of application is wide and the like.

Description

technical field [0001] The invention relates to the fields of environmental management such as pollution reduction and total pollutant discharge control, and in particular to a method for calculating river environmental capacity based on interval numbers. This method can be widely used in the calculation of the water environment capacity of various rivers, and can improve the scientificity and management efficiency of water environment management in river basins. Background technique [0002] At present, the destruction of the water environment has attracted the attention of the world. Water pollution and water resource shortage have become important factors restricting the sustainable development of the economy and society and the improvement of people's living standards. my country began to carry out water pollution prevention and control in the early 1970s. After more than 30 years of efforts, although water pollution has been reduced to a certain extent, it has not been ...

Problems solved by technology

[0004] At present, there is no patent for calculating the capacity of the water environment using the interval number theory. With the strengthening of people's awareness of ecological environment protection, the society attaches great importance to the quality of the water environment. Controlling the pollutants discharged into the water body and improving the quality of the water body have become the stable development of the current society. Urgent need to promote continuous improvement of environmental capacity calculation methods
