Small-size double vortex-shaped line type electrochemical wastewater heavy metal detection and treatment device

Abstract

The invention provides a small-size double vortex-shaped line type electrochemical wastewater heavy metal detection and treatment device which is used for continuously discharging a small amount of wastewater and treating heavy metal ions. A side wall with a double line-vortex-shaped line structure is connected with an outer end to form a reaction tank. A detection unit and a treatment unit are arranged at two sides of the side wall respectively, and each of the detection unit and the treatment unit is composed of an electrode. The wastewater containing the heavy metal ions flows into a sample tank from the top through the center of a first group of vortex-shaped line, and flows through the first group of vortex-shaped line from inside to outside and flows into a second group of vortex-shaped line from outside to inside; finally, the wastewater flows out from the bottom of the reaction tank through the center of the second group of vortex-shaped line. The detection unit is used for processing a heavy metal ion signal of the wastewater through a circuit and then adjusting a current size of the treatment unit. The electrode distance between negative and positive electrodes of the reaction tank is small so that the detection limit of a low-concentration sample is improved; the reaction tank has a long path and an arc-shaped structure; the wastewater flows smoothly and the stability of electrochemical treatment is improved. The plurality of groups of reaction tanks can be connected in series from top to bottom to form a multi-graded reaction tank, so that the treatment capability of the heavy metal ions in the wastewater is improved.

Description

technical field [0001] The invention relates to a small double-scroll line type electrochemical wastewater heavy metal detection and treatment device, especially suitable for the detection and treatment of heavy metal ions in a small amount of continuously discharged wastewater. Background technique [0002] With the development of science and technology, the accompanying environmental pollution is becoming more and more serious. Environmental pollution mainly includes air pollution and water pollution. Among them, heavy metal ion pollution is an important part of water pollution, and once heavy metal pollution enters the water circulation, it is difficult to deal with and poses a direct threat to human health. Therefore, in industrial production, scientific research and chemical experiments, heavy metal ions in wastewater should be treated in time. [0003] At present, the conventional treatment methods for heavy metal wastewater include chemical precipitation method, bio...
