Method for establishing hybrid type rare earth mining area water environment quality monitoring and early warning system

Abstract

The invention discloses a method for establishing a hybrid type rare earth mining area water environment quality monitoring and early warning system and belongs to the environmental quality early warning system field. The method of the invention comprises the following steps that: a pollutant monitoring system is established; a data transmission system is built; an early warning system is established; and an information distribution system and a disposal and decision making system are established. According to the establishment method of the invention, based on the pollution characteristics of hybrid type rare earth mining area water environments in China, the pollutant monitoring system is improved, the information acquisition and output system is built, the rare earth mining area water environment quality early warning technology system is improved, and the accident disposal and decision making system is established, and therefore, the method can be utilized to establish an effective hybrid type rare earth mining area water environment quality monitoring and early warning system. With the method of the invention adopted, important theoretical guidance can be provided for hybrid type rare earth mining area water environment quality management and emergency response disposal work. The method has a bright application prospect.

Description

technical field [0001] The invention belongs to the field of environmental quality early warning systems, in particular to a method for establishing a water environment quality monitoring and early warning system in mixed rare earth mining areas. Background technique [0002] Mixed rare earth production enterprises produce a large amount of high-concentration wastewater containing fluorine (mainly hydrofluoric acid), sulfuric acid, hydrochloric acid, ammonium salt, ammonia nitrogen, radioactive thorium and uranium during the production process, with a content of several thousand to tens of thousands of milligrams per liter. These wastewaters are different from those of general industrial and mining enterprises. They have the characteristics of high concentration, high acidity, large discharge volume, long duration, high radioactive content, and difficult treatment. They have seriously polluted surface water and groundwater, and disputes continue. The water quality safety sit...

Problems solved by technology

However, the water quality monitoring and early warning platform for drinking water sources cannot be applied to the water quality early warning work in rare earth mining areas. The main reason is that the two water quality pollution characteristics are different.
