Abstract

The invention discloses a heavy metal wastewater treatment apparatus, which comprises an outer shell, an inner shell, a stirring device and a water distribution device. The side wall of the outer shell is provided with a controller; the water distribution device comprises a water distributor and an annular water tank respectively arranged at the inner and outer sides of the inner shell; the annular water tank communicates with the water distributor through a tube; a first solenoid valve is arranged on the tube; an electromagnetic switch is arranged on the top of the inner shell; the central part of the inner shell is provided with a filter membrane component which divides the interior of the inner shell into an adsorption zone and a wastewater buffer zone; an exhaust fan is arranged on theinner shell; a pH detector is arranged in the adsorption zone; a water level sensor is arranged in the wastewater buffer zone; the bottoms of the inner shell and the outer shell are respectively a first drain pipe and a second drain pipe; and the free end of the first drain pipe is provided with a second solenoid valve. The apparatus of the invention can effectively solve the problems of poor treatment effect, inconvenient material feeding and uncontrollable treatment speed of conventional treatment apparatuses.

Description

technical field [0001] The invention belongs to the technical field of wastewater treatment, and in particular relates to a heavy metal wastewater treatment device. Background technique [0002] Heavy metals refer to metals with a specific gravity greater than 4 or 5, and there are about 45 kinds. The usual heavy metal pollution mainly refers to the environmental pollution of heavy metals with significant biological toxicity such as mercury, lead, cadmium, chromium, and arsenic, and also includes heavy metals with certain toxicity such as Zinc, copper, cobalt, nickel, tin, vanadium, etc. Heavy metal pollutants are difficult to control. When they accumulate to a certain limit in the water body, they will cause serious harm to the water body-aquatic plant-aquatic animal system, and may affect human health through the food chain. Heavy metal wastewater is produced in many production processes in industries such as mining, machinery manufacturing, chemical industry, electronics...
