Abstract

The invention provides a heavy metal remover and a preparation method thereof, and relates to the technical field of water treatment. The heavy metal remover is prepared from the following raw materials in parts by weight: 40 to 60 parts of polyferric sulfate, 30 to 40 parts of polyacrylamide, 10 to 20 parts of potassium nitrate, 5 to 10 parts of potassium permanganate, 20 to 30 parts of active white mud, 10 to 20 parts of diatomite, 8 to 16 parts of micro-electrolysis iron-carbon filler, 6 to 10 parts of humic acid weathered coal and 4 to 6 parts of dispersing agent. Compared with a traditional heavy metal remover, the prepared heavy metal remover has a better removal effect on ions such as cadmium, chromium, arsenic, lead and nickel, complex in wastewater can be subjected to complex breaking treatment through raw materials in the remover, so that heavy metal in the wastewater can form insoluble precipitates more easily, and the heavy metal removal efficiency is improved. The treatment of heavy metal ions in the wastewater is accelerated.

Description

Technical field [0001] The present invention relates to the field of water treatment techniques, in particular a heavy metal removing agent and a preparation method thereof. Background technique [0002] Heavy metal ions refers to the ionic state of weight metal loss of electrons. Most of the heavy metal ions are produced during industrial production. If it is not handled, it will cause heavy metal pollution in the natural world. Therefore, heavy metal ions in industrial wastewater are also an important link. At present, heavy metal wastewater treatment is roughly It can be divided into two categories: one is to convert heavy metals in wastewater into insoluble heavy metal compound or elements, removed from wastewater, and precipitation, sulfide precipitation, and floating separation method , Ion flotation method, electrolytic precipitation, etc.; Second, heavy metals in wastewater are concentrated and separated without changing its chemical form, and can apply reverse osmosis, e...
