Rain sewage storage tank operation efficiency evaluation method

Abstract

The present invention provides a rain sewage storage tank operation efficiency evaluation method. The method comprises the following steps: a model construction step: establishing a rain sewage storage tank pipe network model according to basic data of a drainage pipe network; a data acquisition step: acquiring operating data of each node of the drainage pipe network, and writing the operating data into a corresponding node in the model; a parameter setting step: setting operating data before operation of a rain sewage storage tank or a design parameter of the rain sewage storage tank to be a reference parameter; an indicator calculation step: calculating a closure capability indicator, a flood drainage capability indicator and a utilization capability indicator according to the operating data of the rain sewage storage tank pipe network model; and an efficiency evaluation step: comparing the closure capability indicator, the flood drainage capability indicator and the utilization capability indicator with the reference parameter, so as to obtain an evaluation result. According to the method provided by the present invention, the overall operation efficiency of the rain sewage storage tank is comprehensively reflected by means of a multi-level indicator evaluation system, and the method can also be used for layout optimization of the rain sewage storage tank and operating mode optimization of the rain sewage storage tank in an operating stage.

Description

technical field [0001] The invention relates to the technical field of municipal drainage, in particular to a method for evaluating the operational efficiency of a rainwater storage tank. Background technique [0002] The rainwater storage tank is a kind of rainwater collection facility, which mainly temporarily stores the peak flow of rainwater runoff in it. After the flow of rainwater runoff drops, the rainwater is slowly discharged from the rainwater storage tank. The application of the rainwater storage tank can effectively avoid the rainwater flood peak, realize the recycling of rainwater, and effectively avoid the pollution of the receiving water body by the initial rainwater, and play a positive role in the drainage scheduling between drainage areas. [0003] At present, due to the constraints of historical conditions and objective factors in many cities, the drainage system in the old city cannot be completely upgraded to a more efficient diversion system, and the co...

Problems solved by technology

[0005] However, due to the lack of basic operational monitoring data in the currently used rainwater storage tank system, it is impossible to quantitatively evaluate indicators such as the load status of the drainage network, the mixed flow of rainwater and sewage, and the operational efficiency of the storage tank. Due to the lack of necessary data support for the layout and design of the stormwater storage tank, the rainwater storage tank cannot exert its maximum performance, and may even cause capital waste and energy consumption
