Pollutant fluctuation coefficient determination method and device, pollutant monitoring method and device and storage medium

Abstract

The invention belongs to the technical field of water environment management and big data, and discloses a method and a device for determining a fluctuation coefficient of instant sampling monitoring values of conventional pollutants (COD (Chemical Oxygen Demand) and ammonia nitrogen) on a daily mean value, a water pollutant automatic monitoring standard exceeding early warning method and a device, and a computer storage medium. The fluctuation coefficient determination method comprises the following steps: monitoring the content of at least one pollutant in a current environment in a first preset period to generate first monitoring data; calculating a logarithm of the first monitoring data in each first time length by taking a set parameter as a base, and calculating a second deviation by taking the calculated logarithm as a standard; obtaining a median of the second deviation within the second duration; and determining a fluctuation coefficient of the instant sampling monitoring value to the daily mean value based on the median of the second deviation. The method provided by the invention can provide support for optimized operation of a sewage treatment process.

Description

technical field [0001] The invention belongs to the field of water environment management and big data technology, and in particular relates to a method and device for determining the fluctuation coefficient of real-time sampling and monitoring values ​​of conventional pollutants (COD, ammonia nitrogen) to daily average values, a method and device for automatic monitoring of water pollutants exceeding the standard, and a computer storage device. medium. Background technique [0002] In the actual sewage treatment process, various factors such as the operation of sewage treatment facilities and natural conditions (such as temperature) will lead to fluctuations in the concentration of water pollutants. The chemical oxygen demand (Chemical Oxygen Demand, COD) and ammonia nitrogen automatic online monitoring facilities can obtain the online monitoring data of the corresponding two pollutants. Mastering the fluctuation characteristics of water pollutant discharge concentration c...
