Embodiment Construction

[0024] The content of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] Such as figure 1 Shown, a method for removing heavy metal ions in sewage, the steps are as follows:

[0026] S1. Filter the sewage through the filter membrane to remove the sediment in the sewage. The specification of the filter membrane is 2 to 3 μm, preferably 2.5 μm in the present invention.

[0027] S2. Install a plurality of adsorption blocks 2 in the adsorption tank 1, and splicing the plurality of adsorption blocks 2 into a plurality of adsorption blocks with a zigzag structure, and splicing a plurality of adsorption blocks with a zigzag structure into a strip shape The strip filter element is distributed in the adsorption tank 1, and the sewage is injected from one end of the adsorption tank 1 through the power pump 3, so that the sewage can absorb heavy metal ions through a plurality of adsorption blocks 2 in the adsorption ta...

Abstract

The invention discloses a method for removing heavy metal ions in sewage and an adsorption device. The method comprises the following steps: pumping in sewage from one end of an adsorption tank through a power pump to enable a plurality of adsorption blocks in the adsorption tank to adsorb the heavy metal ions; and then discharging the sewage of which the adsorption is finished from the other endof the adsorption tank for collection. The adsorption device comprises the adsorption tank, the plurality of adsorption blocks and the power pump, wherein the adsorption tank is of a strip-shaped structure. The adsorption mode is efficient and unique, the adsorption efficiency is high, meanwhile, the adsorption capabilities of the adsorption blocks cannot be reduced sharply, the service life is long and the cost is low.

Description

technical field [0001] The invention relates to a method for removing heavy metal ions in sewage. Background technique [0002] With the development of the economy and the continuous improvement of the industrial level, the increasing pollution of heavy metals has become one of the main threats to human health and the ecological environment. Usually, the main source of heavy metal pollution is industrial pollution, and industrial pollution is mostly discharged into the environment through waste residue, waste water, and waste gas, and is enriched in humans, animals, and plants, thereby causing great harm to the environment and human health. The non-biodegradability and bioaccumulation of heavy metal ions are the main reasons why they can cause great harm. Therefore, heavy metal pollution has attracted great attention of scientists all over the world, and it is urgent to solve this problem. [0003] At present, in the field of sewage treatment containing heavy metal ions, t...
