Problems solved by technology

[0003] The existing heavy metal remover has a poor settling effect on heavy metal ions, which leads to poor removal efficiency of heavy metal ions, which in turn leads to poor practicability. Therefore, for the improvement of the existing heavy metal remover, it is necessary to design a It is particularly important to develop a new type of heavy metal remover to change the above-mentioned technical defects and improve the overall practicability of the heavy metal remover

Abstract

The invention relates to the technical field of heavy metal removing agents, particularly to a heavy metal removing agent, which comprises the following components in parts by weight: 10-15 parts of pH regulator, 12-18 parts of sepiolite, 15-20 parts of polyferric sulfate, 12-18 parts of ferrous sulfate, 1-2 parts of chelating agent and the balance of sodium carbonate. According to the scheme, metal ions such as cadmium, chromium, arsenic, lead, nickel and the like can be quickly settled and removed, so that the heavy metal removing agent provided by the scheme is higher in practicability.

Description

technical field [0001] The invention relates to the technical field of heavy metal removers, in particular to a heavy metal remover. Background technique [0002] Heavy metal remover is the general name of agents that specifically remove heavy metals and arsenic in wastewater in sewage treatment. Heavy metal remover is a chemical agent that chemically reacts heavy metals and arsenic in wastewater by adding heavy metal remover to form water-insoluble Substances can be separated from water, so that waste water becomes clear water, with less sludge and high concentration of heavy metals, which can be recycled and smelted. Application fields: mining, metal smelting and processing, chemical production, electroplating, electronics, printing and dyeing and other industries. [0003] The existing heavy metal remover has a poor settling effect on heavy metal ions, which leads to poor removal efficiency of heavy metal ions, which in turn leads to poor practicability. Therefore, for th...
