Water heavy metal pollution monitoring method

Abstract

The invention discloses a water body heavy metal pollution monitoring method, and belongs to the technical field of water treatment. According to the invention, simulation net cages can be innovatively and vertically put into different areas in a water body; heavy metal isolation is performed with an external water environment; exchange flow of heavy metal ions is prevented; but water flow is notaffected, the simulation net cages simulate the water body environment; the environment in each simulation net cage is partitioned through vertical partition plates and transverse partition plates; the simulation net cage is forced to carry out natural evolution of heavy metal ions in a water body large environment; therefore, the contents and the content change rules of the heavy metal ions in different areas are obtained in a targeted manner; points are sampled on site, and calculation and comparison are performed on the on-site sampled points and the simulation net cages, so that errors arecontrolled, then a mathematical scale model is established, the environment in the simulation net cages is amplified to the whole water body environment, the water body heavy metal pollution data canbe acquired more accurately and comprehensively, the acquired data is more persuasive and has dynamic variability.

Description

technical field [0001] The invention relates to the technical field of water body treatment, and more specifically, to a method for monitoring heavy metal pollution in water. Background technique [0002] Water heavy metal pollution refers to the pollution of water bodies caused by pollutants containing heavy metal ions entering water bodies. Heavy metal wastewater (containing chromium, cadmium, copper, mercury, nickel, zinc and other heavy metal ions) produced in industrial production processes such as mining and metallurgy, machinery manufacturing, chemical industry, electronics, and instrumentation is the most serious water pollution and the most harmful industry to humans. One of the wastewater. Heavy metals in wastewater cannot be decomposed and destroyed by various common water treatment methods, but can only transfer their existing locations and change their physical and chemical states. [0003] Heavy metal ion pollution in water Therefore, heavy metal wastewater s...

Problems solved by technology

[0004] At present, most of the monitoring methods for heavy metal pollution in water are fixed-point monitoring. Although it is more convenient, the monitoring error is relatively large, especially due to the fluidity of the water body, the heavy metal content varies greatly, and the distribution of heavy metal content in the sediment of the water body is also related to the water body itself. Certain differences, therefore, traditional monitoring methods obviously have great limitations
