Method for agile monitoring of water quality of pig breeding sewage

Abstract

The invention discloses a method for agile monitoring of the water quality of live pig breeding sewage. The method comprises the following steps: sampling sewage in a live pig breeding sewage treatment process, selecting a modeling sample and an inspection sample, and quantitatively detecting each water quality index in the samples; constructing a corresponding regression model based on the threeindexes with significant correlation; screening out a regression model with a good fitting effect; verifying the accuracy of the regression model based on the data of the inspection sample and a measured value; carrying out comprehensive modeling on the three indexes of NH3-N, EC and TN; and finally, obtaining an optimal regression model for NH3-N and TN. Aiming at TP and COD, respectively establishing linear regression models; and based on the obtained regression model, determining an agile pig breeding sewage monitoring scheme. The method solves the problems of large water quality index measurement difficulty coefficient, high cost and low efficiency in the traditional livestock and poultry breeding sewage quality monitoring scheme, and effectively improves the monitoring efficiency.

Description

technical field [0001] The invention relates to the technical field of sewage monitoring, in particular to a method for agile monitoring of pig breeding sewage water quality. Background technique [0002] At present, the composition of pig breeding sewage is complex, and the concentration of pollutants contained in it is high, which can easily cause eutrophication of the downstream surface and groundwater, and pose a great threat to the ecological environment. For many years, the purification method, treatment process, and removal method of main indicators of pig breeding sewage have always been research hotspots. According to different treatment processes, the treatment methods of pig breeding sewage mainly include ecological treatment, industrial treatment and centralized treatment. Among them, the sewage after industrial treatment has pollution risks due to discharge into natural water bodies. The water quality monitoring of the pig breeding sewage after industrial treat...
