Joint debugging and joint control method for guaranteeing biosafety of pipe network water quality based on real-time ArcGis

Abstract

The invention relates to a joint debugging and joint control method for guaranteeing biosafety of pipe network water quality based on real-time ArcGis. The method comprises the following steps: (1) importing the residual chlorine data of each water quality monitoring point of a water supply pipe network into a geographic information system; (2) according to the distribution of water works,, secondary pressurized pump stations and transmission and distribution pipe networks, analyzing the spatial variation rule of disinfectant attenuation in the water of current transmission and distribution pipe network to regulate and control residual chlorine of the pipe network; (3) performing secondary analysis on the distribution of residual chlorine of the pipe network, observing whether the most disadvantageous point of the pipe network transmission and distribution satisfy the minimum value of the residual chlorine required for model calculation to control a microbial indicator to be qualified; and (4) if the most disadvantageous point of the pipe network transmission and distribution cannot satisfy the minimum value required for the model, repeating the step (2) until the residual chlorine distribution of the pipe network basically satisfies the microbial indicator control condition at the most disadvantageous point in the pipe network transmission and distribution. Through the invention, the microbial indicator of the pipe network reaches the standard, the spatial distribution of the residual chlorine of the pipe network is more uniform, and the addition of disinfectant and the amount of disinfection byproduct are reduced.

Description

technical field [0001] The invention relates to a technical method for ensuring the safety of microorganisms in pipe network water quality, in particular to a method of regulating the residual chlorine in the effluent of an existing secondary pressurized pump station through a statistical model, and displaying the water supply area regulation in real time through ArcGis (geographic information system). The method of joint regulation and joint control technology for the effective pipeline network water quality biosafety assurance. Background technique [0002] The problems of drinking water pollution are diverse and complex. To provide users with safe and high-quality drinking water, water supply companies must face the entire water supply system, take corresponding safety measures from water sources, water plants, pipe networks to faucets, and seek systematic technical solutions. The underground water supply pipe network and secondary water supply system are located at the ...

Problems solved by technology

Although the analysis of simulation results and the dynamic residual chlorine contour map drawn by the system can reflect the residual chlorine attenuation status of the water supply network at different times, but for the reality of the distribution of multiple water sources and multiple pressurized pump stations in many cities, the contour map and The display effect of the isosurface map is still complicated, and its attenu
