Early warning device and method for identifying sudden water pollution based on biotic population module

Abstract

The invention discloses an early warning device for identifying sudden water pollution based on a biotic pollution module. The early warning device comprises a biotic population placing unit (1), a biotic population monitoring unit and an alarming unit (27). The biotic population placing unit is a group of parallel module type series-connection water tanks; the biotic population monitoring unit comprises three sets of independent devices, namely a fish monitoring device, a demersal invertebrate monitoring device and a protist monitoring device. The invention further provides a method for identifying the sudden water pollution based on the biotic pollution module in a quantitative mode. The early warning device and method for identifying the sudden water pollution based on the biotic pollution module overcome the defects that an existing water quality biology early warning technology can only early warn whether water pollution exists or not in a qualitative mode, but cannot early warn the severity of water pollution in a quantitative mode. The early warning device and method for identifying the sudden water pollution based on the biotic pollution module meanwhile overcome the defects that the existing water quality biology early warning technology can only early warn limited varieties of pollutants, but cannot meanwhile early warn various water pollutants. Thus, the monitoring range is wider, sensitivity is higher and accuracy is better.

Description

technical field [0001] The invention relates to an early warning device and method for sudden water pollution, in particular to an early warning device and method for identifying sudden water pollution based on biological population blocks, and belongs to the technical field of water environment protection. Background technique [0002] Sudden water pollution accidents refer to extreme water environmental events in which a large number of high-concentration pollutants are discharged into water bodies in a short period of time, seriously damaging the normal use functions of natural water bodies. In the process of rapid industrialization, more and more chemicals are used, and major sudden water pollution accidents occur frequently. Sudden water pollution seriously threatens the health of residents, industrial and agricultural production, and ecological security. Improper handling will cause far-reaching negative social, economic, and ecological effects. Establishing an early ...

AI Technical Summary

Problems solved by technology

Since a single organism is only sensitive to several fixed pollutants, it cannot make a biological mutation response to pollutants beyond the range, so the effective monitoring range of conventional biological early warning methods is relatively limited.

[0005] (2) The current online biomonitoring technology can only use a single species to warn of sudden changes in water quality, so it can only achieve single-level qualitative identification, that is, it can only judge whether water pollution occurs, but cannot distinguish the severity of pollution. Provide quantitative information support for emergency response to sudden water pollution
