Embodiment Construction

[0027] Embodiments of the invention are described in detail below, but the invention can be practiced in many different ways as defined and covered by the claims.

[0028] Explanation of terms:

[0029] (1) The dual water cycle refers to the natural water cycle process of "precipitation-evaporation-runoff-replenishment-excretion" that is not affected by human activities, and the social water cycle of "water supply-water consumption-water consumption-drainage" dominated by human activities process, the coupling of the two considers the water cycle process as a whole, and performs simulation and regulation.

[0030] (2) Water function zone refers to meeting the needs of human beings for the rational development, utilization, conservation and protection of water resources, according to the natural conditions of water resources and the status quo of development and utilization, in accordance with the comprehensive planning of river basins, the protection of water resources and the...

Abstract

The invention relates to an assimilative capacity calculating method based on binary water circulation. The assimilative capacity calculation method includes steps of 1, determining overproof pollutant types of a watercourse; 2, determining water quality target according to the water function area where the watercourse is; 3, determining upstream coming water flow and quality of the water function area so as to determine boundary conditions of pollutant balance of the watercourse; 4, determining comprehensive degradation coefficient of water quality of the watercourse; 5, determining the design flow of the water function area according to the nature-society binary water circulation flow balance of the watercourse; 6, selecting an assimilative capacity calculation model and calculating assimilative capacity of the water function area according to the water quality target, the upstream coming water flow and quality, the comprehensive degradation coefficient of the water quality and the design flow. The assimilative capacity calculating method can calculate how many pollutants are contained in one river while the water quality of the watercourse can be still kept healthy, and accuracy of calculation results is improved.

Description

technical field [0001] The invention relates to the technical field of pollution holding in water areas, in particular to a method for calculating pollution holding capacity based on a binary water cycle. Background technique [0002] The analysis of the pollutant-holding capacity of water areas is the basis of the total amount of water pollution control, and its quantitative accounting is of great significance to the protection of the water environment. The research on the pollution-holding capacity of rivers requires not only qualitative analysis, but also quantification of the pollution-holding capacity, and the premise of quantification is to choose an appropriate calculation method. [0003] The current pollution-holding capacity is mostly calculated using the water conservancy industry standard "Calculation Procedure for Water Sewer Capacity SL348-2006" issued by the Ministry of Water Resources and the national standard "Calculation Procedure for Water Sewer Capacity G...
