Riverway heavy metal treatment system

Abstract

The invention discloses a riverway heavy metal treatment system, which belongs to the technical field of riverway treatment and comprises a cofferdam, a lifting mechanism, a lifting platform, a heavymetal adsorption insertion column and a stirring mechanism, wherein the lifting mechanism is installed on the inner side of the cofferdam and used for driving the lifting table to move up and down, the heavy metal adsorption insertion column and the stirring mechanism are both detachably connected to the lifting table, and the lifting table is located in the cofferdam and located above a water layer; the lower end of the heavy metal adsorption insertion column is inserted into a mud layer, the upper end of the heavy metal adsorption insertion column penetrates through the water layer and thenis connected with the lifting table, the stirring mechanism is located in the middle of the cofferdam, and the stirring mechanism is used for stirring the mud layer and the water layer in the cofferdam and used for driving the lifting table to vibrate. Via the system, heavy metals in a water layer and a mud layer can be effectively removed, and the riverway heavy metal treatment effect is good.

Description

technical field [0001] The invention relates to the technical field of river course management, more specifically, it relates to a river course heavy metal treatment system. Background technique [0002] River sediment refers to the surface sediment at the bottom of the water body, which is composed of sediment, soil, humus and microorganisms. It is the main living place and food source for benthic organisms in the river, and is an important part of the river ecosystem. River sediment is an important part of the river ecosystem and plays a vital role in the purification of river water quality. With the rapid development of society and economy, a large amount of domestic sewage and industrial wastewater are discharged into the river, causing river sediment pollution. It is becoming more and more serious, and the long-term accumulation makes the pollutants in the sediment complex and difficult to remove. Especially the heavy metal pollution caused by industrial development, b...

AI Technical Summary

Problems solved by technology

[0006] 1. Although active agents that promote the dissolution of heavy metals are added to the water in the cofferdam, there are still some heavy metals in the sediment, and the removal of heavy metals is not thorough enough;

[0007] 2. The pipeline connection of the heavy metal adsorption column forms a whole, which is very inconvenient to dismantle and install, especially when the nanoporous ceramic composite particles need to be replaced.
