A combined system pipeline overflow control parameter calculation method and device

Abstract

The invention discloses a combined system pipeline overflow control parameter calculation method and device, and the method comprises the steps of collecting the historical data of a preset time period of a target region, and enabling the target region to comprise a plurality of statistical sites; determining a target control frequency and a session division standard according to a preset planning target; and calculating a control parameter value of the target area according to the historical data of each statistical site, the target control times and the session division standard. Through implementation of the invention, the problem that the actual engineering design efficiency is affected due to the fact that a control target formulated by a management department cannot be directly applied to engineering design in the prior art is solved; by combining historical data of each statistical site, the target control times and the session division standard, the control parameter values for practical engineering application can be obtained through calculation, visual design indexes are provided for designers, the design efficiency of practical engineering is improved, and breakpoints in the planning stage and the practical design stage are avoided.

Description

technical field [0001] The invention relates to the field of water environment treatment, in particular to a calculation method and device for overflow control parameters of combined pipelines. Background technique [0002] Combined Sewer Overflows (CSOs) pollution has become the primary factor restricting the further improvement of the current urban water environment. When controlling combined system overflow pollution, the first problem is to determine the control target. At present, the United States takes controlling the number of overflows as the control goal, and Germany takes controlling the rainfall per unit area as the control goal. [0003] In recent years, domestic combined system overflow pollution control work is also gradually entering the normal track. Most domestic cities use the number of combined system overflows as the control target. For example, Beijing uses 4 times as the control target for combined system overflow, and Wuhan Take 10 times as the cont...
