Abstract

The invention discloses a method for judging the state of microorganisms in a river and selecting purification measures, comprising: taking the suspension of a representative section of the river to analyze the breath pattern, measuring the oxygen consumption rate OUR value; measuring the three-dimensional concentration of dissolved organic matter in each representative section Fluorescence spectrum; divide the three-dimensional fluorescence spectrum into five areas according to the peak position, select the peak T representing the protein-like, the ratio of on-site respiration OURs / OURt and the ratio of endogenous respiration OURe / OURt; draw a bubble diagram, and divide the plane of the bubble diagram into There are 4 areas, different areas correspond to different microbial health conditions and pollution levels and different enhanced purification measures. The invention discloses a method for judging the microbial status of rivers and selecting purification measures. The method of the invention establishes a comprehensive evaluation method for the microbial state and pollution state of the river and the enhanced purification measures. Provide theoretical basis and technical support for strengthening river ecological management.

Description

technical field

[0001] The invention belongs to the field of water conservancy and environmental management, and relates to a method for determining the state of microorganisms in a river and selecting purification measures by measuring river spectrum and breath spectrum and using the combination of breath spectrum and spectrum. Background technique

[0002] River purification is a complex process, involving physical, chemical and biological processes, in which the water body is diluted by its own physical diffusion within a certain time and a certain distance, chemical reactions and biological metabolism degrade complex pollutants in the water body into small molecules or transformation process for other non-hazardous substances. The purification process includes various methods such as dilution, adsorption, precipitation, absorption, physical transformation, chemical transformation and biological transformation, which can be described and evaluated using mathematical model...
