Description

technical field

[0001] The invention relates to the technical field of environmental protection, in particular to a groundwater pollution detection device. Background technique

[0002] With the rapid development of my country's economy and the acceleration of industrialization and urbanization, the problem of groundwater pollution has become increasingly serious and has become the bottleneck of my country's economic development and the harmonious development of the ecological environment. For the governance and control of the water environment, not only the relevant laws and regulations and an effective supervision system are required, but also the water quality testing equipment, which is an important means of protecting the water environment and controlling water pollution, needs to be vigorously developed. Water quality detection can not only accurately reflect the situation of water quality, predict the development trend of water quality, but also provide scientific bas...
