Heavy metal water quality detection device

Abstract

The invention belongs to the technical field of water quality detection, and discloses a heavy metal water quality detector which comprises a pretreatment device, a pre-detection device, a quantitative detection device and a control device, a filter tank and a first stirring piece are arranged in the pretreatment device; the pre-detection device is communicated with the pretreatment device, and a second stirring piece and a turbidity sensor are arranged in the pre-detection device; the quantitative detection device is communicated with the pretreatment device and is used for detecting the content of heavy metal ions in the to-be-detected water sample; the control device comprises a controller, and a control panel, a display screen body and a data storage module which are electrically connected with the controller; the controller is electrically connected with the first stirring piece, the second stirring piece and the turbidity sensor. Whether quantitative detection is needed or not is judged according to the pre-detection result of the to-be-detected water body, then water quality detection is carried out specifically and efficiently, detection is convenient and rapid, and resource waste caused by detection of the water body reaching the standard is avoided while subsequent water sample treatment is guided.

Description

technical field [0001] The invention relates to the technical field of water quality detection, in particular to a heavy metal water quality detection device. Background technique [0002] Heavy metal pollution refers to environmental pollution caused by heavy metals or their compounds. Heavy metal pollution is mainly manifested in water pollution. In order to avoid the damage to the ecological environment caused by heavy metal pollution, in early April 2011, China's first "Twelfth Five-Year" special plan - "Twelfth Five-Year Plan for Comprehensive Prevention and Control of Heavy Metal Pollution" was approved by the State Council. Officially approved, the prevention and control plan strives to control five heavy metals (lead, mercury, cadmium, chromium and metalloid arsenic). [0003] In order to strictly control the pollution of heavy metals to water quality, it is very important to efficiently and accurately detect heavy metals in water. For this reason, the prior art pro...

Problems solved by technology

[0003] In order to strictly control the pollution of heavy metals to water quality, it is very important to accurately detect heavy metals in water efficiently. For this reason, various heavy metal detection methods have been proposed in the prior art, such as atomic absorption spectroscopy and inductively coupled plasma. The concentration of heavy metals at trace levels can be detected, but it needs tens of thousands to hundreds of thousands of dollars for testing. These instruments are not only expensive and cumbersome, but require a lot of reagents, and are not suitable for large-scale on-site surveys
