Description

Technical Field

[0002] Heavy metals refer to metals with a density greater than 4.5g / cm3, including gold, silver, copper, iron, mercury, lead, cadmium, etc. When heavy metals accumulate in the human body to a certain extent, they will cause chronic poisoning. In terms of environmental pollution, heavy metals mainly refer to heavy elements with significant biological toxicity such as mercury, cadmium, lead, chromium and metalloid arsenic. Heavy metals are very difficult to be biodegraded. On the contrary, they can be enriched thousands of times under the biological magnification effect of the food chain and finally enter the human body. Heavy metals can strongly interact with proteins and enzymes in the human body, making them inactive. They may also accumulate in certain organs of the human body, causing chronic poisoning.

[0003] At present, residents living along the river cannot avoid using river water, or even catching fish for food. The sludge at the bottom of the river is easily affected by environmental pollution, resulting in excessive heavy metals, which can easily affect the river water or fish.

Therefore, it is necessary to analyze and detect the heavy metals in the sludge at the bottom of the river to formulate a treatment plan. The existing sludge heavy metal analysis and detection equipment generally samples and detects the sludge on the surface of the riverbed.

Sampling and testing the sludge on the surface of the riverbed is relatively limited, and it is difficult to accurately detect the heavy metal stratification at different depths, which can easily affect the final detection accuracy and has high limitations.
