Abstract

The invention discloses a filter screen for adsorbing heavy metals in industrial wastewater. A main body of the filter screen is a steel filter screen, wherein the steel filter screen is filled with an adsorbent during production; the adsorbent comprises the following components in parts by weight: 20-29 parts of attapulgite, 10-20 parts of pottery clay, 10-16 parts of an expanded graphite cyclodextrin compound, 26-33 parts of activated carbon, 20-29 parts of volcanic rock, 11-19 parts of loofah sponge and 22-29 parts of butyl acetate. Through the filter screen for adsorbing the heavy metals in the industrial wastewater, provided by the invention, the heavy metals in the industrial wastewater can be effectively adsorbed and the adsorption effect is significant.

Description

technical field [0001] The invention relates to the field of filter screens, in particular to a filter screen for absorbing heavy metals in industrial waste water. Background technique [0002] With the development of the economy, there are more and more chemical plants everywhere, and the treatment of industrial wastewater has become a hot spot of concern from all walks of life. Filter screens are needed in the wastewater treatment process, and the existing filter screens are not very effective in adsorbing organic molecules and inorganic heavy metals in wastewater. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a filter net for adsorbing heavy metals in industrial waste water, which can effectively adsorb heavy metals in industrial waste water and has remarkable adsorption effect. [0004] In order to solve the above-mentioned technical problems, a technical solution adopted in the present invention is to pr...
