Method of judging state of river microorganisms and selecting purification measures

Abstract

The invention discloses a method of judging the state of river microorganisms and selecting purification measures, which comprises steps: the suspension of a river representative section is taken to be subjected to respiratory atlas analysis, and an oxygen uptake rate (OUR) is measured; a three-dimensional fluorescence spectrum of a dissolved organic matter in each representative section is measured; the three-dimensional fluorescence spectrum is divided to five regions according to peak positions, and a peak T characterizing plastein, a site respiratory ratio OURs / OURt and an endogenous respiratory ratio OURe / OURt are selected; and a bubble diagram is drawn, the plane of the bubble diagram is divided to four regions, and different regions correspond to different microorganism health states, different contamination degrees and different enhanced purification measures. The invention discloses a method of judging the state of river microorganisms and selecting purification measures. A comprehensive evaluation method for the river microorganism state, the pollution state and the enhanced purification measures is built, and a theoretical basis and a technical support are provided for enhancing ecological management of the river.

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...

Problems solved by technology

[0003] The DO concentration in the Streeter-Phelps BOD-DO system model is the main indicator to measure the health of the river, and it responds to the biochemical oxygen demand (BOD) load, which is traditionally used to express and evaluate the pollution degree of the water body and purification ability, the measurement method is relatively simple, but the mechanism involved is relatively complex, which must be studied through mathematical models

However, the experimental data and calculation process obtained by the DO-BOD model are relatively complicated, and it takes a lot of time and energy for professionals. Therefore, it is urgent to explore a simple and effective evaluation method for river purification capacity.
