Current urban river water quality standard-reaching analysis method based on orthogonal analysis

Abstract

The invention relates to the technical field of water supply and drainage engineering, river regulation, environmental science and engineering and environmental protection, and provides a new urban river water quality standard analysis method which can objectively reflect each influence factor of river water quality. Therefore, the technical scheme adopted by the invention is as follows: a currenturban river water quality standard-reaching analysis method based on orthogonal analysis comprises the following steps: analyzing natural background characteristics of a region where the current urban river water quality standard-reaching analysis method is; constructing and calibrating a riverway hydrodynamic water quality coupling model; carrying out single-factor riverway water quality standard analysis of different influence factors; performing multi-factor river water quality standard analysis based on orthogonal analysis; and optimizing an orthogonal analysis result by active water volume checking and engineering cost analysis, and finally determining boundary conditions and engineering scale of river channel water quality reaching the standard. The method is mainly applied to drainage engineering and river regulation occasions.

Description

technical field [0001] The invention relates to the technical fields of water supply and drainage engineering, river regulation, environmental science and engineering, and environmental protection, in particular to an analysis method for water quality compliance of current urban rivers based on orthogonal analysis. Background technique [0002] Water pollution prevention and control usually strengthens source control, coordinates water and land, and takes into account both rivers and seas, implements scientific governance of rivers, lakes, and seas by basin, region, and stage, and systematically promotes water pollution prevention, water ecological protection, and water resource management. The engineering measures adopted in the water environment improvement project are all centered on reaching the river water quality standards, but there is no relevant demonstration method for whether the engineering measures adopted can ensure the stable river water quality standards. The...

Problems solved by technology

At present, the research based on the coupling model of urban river hydrodynamics and water quality has been widely used in the analysis of river water quality. Since there are many factors affecting water quality, it is a huge workload to comprehensively analyze the factors one by one. In engineering practice, it is often only to simulate different interception flows Under certain conditions, the water quality is up to standard, other
