Embodiment 1

[0019] In parts by weight, mix 7 parts of 60-mesh steel slag (about 10wt% iron content), 2 parts of 100-mesh ferromanganese ore (about 15wt% iron content) and 1 part of 100-mesh coconut shell activated carbon, and then extrude The granulator made spherical granules of about 3 cm; the spherical granules were then placed in a muffle furnace at 210°C for 2 hours and then cooled for later use.

Embodiment 2

[0021] In parts by weight, mix 16 parts of 120 mesh steel slag (about 20wt% iron content), 3 parts of 80 mesh ferromanganese ore (about 25wt% iron content) and 1 part of 100 mesh coconut shell activated carbon, and then extrude The granulator made spherical particles with a size of about 3 cm; the spherical particles were then placed in a muffle furnace and baked at 300°C for 3 hours, then cooled for later use.

Embodiment 3

[0023] In parts by weight, mix 5 parts of 120-mesh steel slag (about 8wt% iron content), 4 parts of 80-mesh ferromanganese ore (about 6wt% iron content) and 1 part of 100-mesh coconut shell activated carbon, and then extrude The granulator made spherical granules of about 3 cm; the spherical granules were then placed in a muffle furnace and baked at 380°C for 4 hours, and cooled for later use.

Abstract

The invention discloses an underground water tungsten pollution remediation material. The underground water tungsten pollution remediation material is prepared from, by mass, 5-16 parts of steel slag with the iron content of 7-20%, 2-4 parts of iron-containing manganese ore with the iron content of 5-25 % and 1 part of activated carbon. The raw materials are evenly mixed and granulated and then are calcinated for 1 to 5 hours at the temperature of 200-400 DEG C to obtain the remediation material. The raw materials required by the remediation material are common, the preparation process is simple, and the remediation material can be obtained only by evenly mixing and calcinating the raw materials. The remediation material has obvious fixing effect on tungsten in underground water and can remarkably reduce the tungsten content of the underground water and strengthen the ecological safety. The remediation material is applicable to underground water different in tungsten pollution degree and can be in contact with underground water for different periods of time according to the actual situation so as to improve the removal effect, and a fixing agent is low in cost and is economically feasible.

Description

technical field [0001] The invention relates to a groundwater tungsten pollution restoration material, which belongs to the field of underground tungsten pollution control water. Background technique [0002] Tungsten is a transition heavy metal element in the VIB group of the sixth period of the periodic table. my country's tungsten reserves account for 41% of the world's tungsten reserves, which is 820,000 tons; the reserve base accounts for 37.5% of the world's total, which is 1.2 million tons, ranking first in the world. The main metallogenic belts are distributed in provinces and cities such as Guangdong, Jiangxi, Guangxi, Hunan and Fujian. In recent years, unreasonable tungsten mining has caused serious water pollution including groundwater pollution in tungsten mining areas. Groundwater is one of the natural resources that human beings rely on for survival. Heavy metal tungsten pollution and environmental and ecological problems have seriously affected the sustainab...
