Equipment for adsorbing heavy metal elements

Abstract

The invention provides equipment for adsorbing heavy metal elements, and belongs to the technical field of sewage treatment. The equipment for adsorbing the heavy metal elements comprises a treatment channel which comprises a first treatment channel, an arc-shaped treatment channel, a second treatment channel and a conical connecting pipe; the first treatment channel, the arc-shaped treatment channel, the second treatment channel and the conical connecting pipe are sequentially communicated from top to bottom, a recoverable adsorption mechanism is arranged in the first treatment channel, and the recoverable adsorption mechanism comprises two electric telescopic rods. The whole device is reasonable in structural arrangement, ingenious in conception, convenient to use, and suitable for batch adsorption or batch treatment of heavy metal elements in sewage, the treatment efficiency is high, the effect is good, the adsorbed heavy metal elements can be extracted through the device, operation is convenient, a flow guide mechanism in the device prevents the heavy metal elements from blocking the microwell plate, and the whole treatment channel is compact in structure, low in machining cost and high in practicability .

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to equipment for adsorbing heavy metal elements. Background technique [0002] With the development of social economy, a large amount of sewage is produced every day, including sludge with high water content, hydrolyzate and other waste liquids. Sludge contains a large amount of harmful substances such as heavy metals, pathogens, insect eggs, and refractory organic matter. Sludge that has not been treated for environmental protection is very harmful to the environment. The heavy metal ions in these sewage not only pose a threat to environmental protection and species diversity, but also seriously affect human physical and mental health. In order to avoid environmental pollution and realize resource reuse, it is necessary to carry out harmless treatment of these sludges, hydrolyzate and other waste liquids with high water content. The first step in the treatmen...

Problems solved by technology

[0004] The purpose of the present invention is to provide a kind of equipment for adsorbing heavy metal elements, aiming to solve the problem of heavy metal element treatment devices in sewage usually adopting chemical precipitation method, electrolysis method, ion exchange method, membrane separation method, activated carbon or silica gel adsorption in the prior art. However, when adsorbing heavy metal elements, the adsorbed heavy metal elements cannot be collected. At the same time, the structure of the device is more complicated, and the waste of resources is more serious.
