Abstract

The invention discloses a method for quick predicting total bacterial count of a potable water network based on BP (Back Propagation) neural network, comprising the following steps of (1) acquiring the total bacterial count of the tested potable water network and other related water quality index values influencing the count as detection data; (2) establishing an error-based backpropagation neural network; (3) training and testing the neural network; and (4) predict the total bacterial count of the potable water network by utilizing the neural network passed the test. The invention can establish a prediction model of the total bacterial count of the potable water network by 6 water quality indexes having high relativity with the total bacterial count and being quick tested and obtained by instruments only through limited tests, accurately and quickly predict the total bacterial count in the potable water network through computer simulation tests and scientific prediction, provide reliable information for water supply enterprises and guarantee bacteriological water quality security of the water supply network.

Description

technical field [0001] The invention relates to a method for predicting the total number of bacteria in a drinking water pipe network, in particular to a method for predicting the total number of bacteria in drinking water based on a BP neural network capable of accurately and rapidly predicting the total number of bacteria in the drinking water pipe network. Background technique [0002] Bacteriological water quality safety of drinking water pipe network is a common concern of water supply enterprises and users. When the factory water is transmitted through the water distribution system, complex physical, chemical and biological effects will occur in the pipeline, resulting in changes in water quality. At present, although researchers have paid more and more attention to simulating the growth of microorganisms, establishing a related model of microbial growth to replace the traditional method of counting microorganisms that is time-consuming and has poor accuracy. However,...
