TL;DR: In this article, a positioning method for pressure-correlated leakage of a water supply network is proposed, which includes the following steps that S1, a simulation model is established as a micro model; S2, the water flow state of the water supply networks is monitored in real time, water flow parameters including real-time pressure data and flow data of all nodes in the network are collected; S3, the currently collected water flow flow parameters are attached to the micro model, and S4, a micro-hydraulic model is used to simulate the transient water flow

TL;DR: In this article, a method for measuring the VFA concentration in the anaerobic wastewater treatment process by means of near infrared spectrum comprises the steps of 1, taking N wastewater samples in the typical cycle, measuring the vFO concentration of the n wastewater samples with the gas chromatographic method, and measuring the original near infrared spectrometer; 2, pretreating original near-infrared spectrum data through wavelet transform; 3, establishing a calibration model based on the VFO concentration and a pretreated spectrogram, calculating the correlation coefficient, adopting the calibration model when the

TL;DR: In this article, a treatment system for high carbon and nitrogen wastewater is described, which consists of a regulating pool, lifting pump, a coagulative precipitation pool, a hydrolysis-acidification pool, another lifting pump and an IC (internal circulation) reactor.
