Water environment heavy metal pollution treatment device

Abstract

The invention discloses a water environment heavy metal pollution treatment device. The water environment heavy metal pollution treatment device comprises a treatment tank main body; the treatment tank main body is divided into four parts by separating plates, and comprises an adsorption tank, an electrolysis tank, a reaction tank, and a sedimentation tank from left to right successively; the tops of the separating plates are provided with overflow grooves; one end of the top of the adsorption tank is provided with a water inlet pipe; an active carbon adsorption screen is arranged in the adsorption tank; an electrode is arranged in the electrolysis tank; the top of the electrode is provided with a guide line. According to the water environment heavy metal pollution treatment device, the treatment tank main body is provided with the adsorption tank, the electrolysis tank, the reaction tank, and the sedimentation tank, so that purifying effect on a plurality of heavy metals in waste water is increased; stirring blades are arranged in the sedimentation tank, and are driven to rotate by a motor, so that reaction of heavy metals in waste water with heavy metal catalysts in the reaction tank is more complete, purifying speed and efficiency of the water environment heavy metal pollution treatment device are improved, and the practicality of the water environment heavy metal pollution treatment device is increased.

Description

technical field [0001] The invention relates to the technical field of heavy metal treatment, in particular to a water environment heavy metal pollution control device. Background technique [0002] The original meaning of heavy metals refers to metals with a specific gravity greater than 5 (generally speaking, metals with a density greater than 4.5 grams per cubic centimeter), including gold, silver, copper, iron, lead, etc. Heavy metals accumulate in the human body to a certain extent and can cause chronic poisoning . In fact, there is no strict unified definition of what is a heavy metal. In terms of environmental pollution, heavy metals mainly refer to heavy elements with significant biological toxicity such as mercury (mercury), cadmium, lead, chromium, and metalloid arsenic. Heavy metals cannot be biodegraded, on the contrary, they can be enriched by hundreds of times under the biomagnification of the food chain, and finally enter the human body. Heavy metals can str...
