Description

technical field [0001] The invention belongs to the field of environmental monitoring, in particular to a multi-parameter water quality rapid detection device based on ARM technology. Background technique [0002] At present, more than 420 billion cubic meters of sewage are discharged into rivers, lakes and seas in the world every year, polluting 5.5 trillion cubic meters of fresh water, which is equivalent to more than 14% of the total global runoff. In recent years, with the rapid development of my country's economy, a large number of industrial, agricultural and domestic wastes have been discharged into the water, polluting the water body. According to monitoring by the environmental department, at least 100 million tons of untreated sewage is discharged directly into water bodies every day in cities and towns across the country. The water quality of more than half of the country's seven major water systems is polluted, 1 / 3 of the country's water bodies are not suitable ...
