Device, system and method for long-term monitoring of comprehensive ecotoxicity of standard sewage and wastewater

Abstract

The invention discloses a device, a system and a method for long-term monitoring of comprehensive ecotoxicity of standard sewage and wastewater. The device comprises a water inlet pipe, a cylinder, alight source, a water quality online monitoring device, a monitoring camera, a toxicity monitoring screen box, an overflowing groove and a water outlet pipe, the cylinder is used for building a miniature water ecological device, the water inlet pipe is connected with the cylinder and used for draining water to be monitored into the cylinder, the light source is arranged on the upper portion of thecylinder and used for simulating illumination of sunlight for water, the water quality online monitoring device is used for detecting water quality parameters of the water, the toxicity monitoring screen box is arranged in the cylinder and used for breeding aquatic animals serving as a target creature, the monitoring camera is arranged above the toxicity monitoring screen box and used for survival statuses of aquatic animals in real time, the overflowing groove is formed in the cylinder, and the water outlet pipe is communicated with the cylinder through the overflowing groove and used for discharging water and keeping basic constant volume of the water.

Description

technical field [0001] The invention relates to the technical field of environmental water quality monitoring, in particular to a device, system and method for long-term monitoring of comprehensive ecotoxicity of up-to-standard sewage and wastewater. Background technique [0002] The rapid development of industrialization and urbanization has produced a large amount of industrial and domestic sewage. Wastewater contains various types of pollutants, and its toxic effects are worthy of attention. [0003] At present, the toxicity monitoring of wastewater is mainly based on the analysis of physical and chemical indicators and the monitoring of biological acute toxicity. Traditional physical and chemical analysis can detect the types and concentrations of toxic chemicals in water under limited conditions, but the existing technology cannot identify all species in water. Toxic pollutants; biological toxicity monitoring can intuitively reflect the environmental ecological effects ...

AI Technical Summary

Problems solved by technology

[0006] The present invention aims to overcome the existing water quality biological monitoring methods and devices that do not have a water ecosystem that imitates natural conditions, cannot monitor the toxic effects of low-concentration pollutants for a long time, and need to regularly replace the tested organisms and need to feed the tested organisms for a long time Defects such as food, thus a new method and field device for comprehensive ecotoxicity monitoring of discharge sewage and wastewater based on micro-aquatic ecosystems are proposed
