Environment restoration material, preparation method and application thereof

Abstract

The invention provides an environment restoration material, a preparation method and application thereof, and relates to the technical field of environmental remediation. The preparation method comprises the following specific steps: S1, carrying out a neutralization reaction on a proper amount of acrylic acid and a sodium hydroxide solution by using a reaction kettle; S2, after the neutralization reaction is completed, injecting the mixed solution into a mixing device, adding a methylene bisacrylamide cross-linking agent into the mixing device, stirring for 10-15 minutes, adding a proper amount of bacillus polymyxa powder and activated carbon powder into the mixed solution, and continuously stirring for 20 minutes; and S3, after cross-linking mixing is completed, adding an ammonium persulfate solution into the mixing device, continuously stirring, controlling the temperature at 40 DEG C, adding a proper amount of a sodium sulfite aqueous solution into the stirred reaction solution, and stirring for 1-2 minutes. According to the invention, by adopting a super absorbent resin as a matrix and compounding a targeted pollutant adsorption material, heavy metal ions exceeding the standard in a polluted water body can be subjected to targeted adsorption treatment, so that the overall working efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of environmental restoration, in particular to an environmental restoration material and its preparation method and application. Background technique [0002] Water pollution is caused by harmful chemical substances that reduce or lose the use value of water and pollute the environment; acids, alkalis, oxidants in sewage, and compounds such as copper, cadmium, mercury, arsenic, benzene, dichloroethane, ethylene dichloride, etc. Alcohol and other organic poisons will kill aquatic organisms and affect drinking water sources and scenic spots; industrial "three wastes" (waste water, waste gas, waste residue) are one of the main factors of water pollution in my country. Industrial wastewater such as industrial electroplating wastewater, industrial acid Washing sewage, smelting industrial wastewater, light industrial wastewater and petrochemical organic wastewater are discharged into urban sewers, rivers, lakes and ...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides an environmental repair material and its preparation method and application, which solves the problem that after the incompletely treated and purified industrial wastewater is discharged into large seepage pits or small river and lake water bodies, although the sewage has passed through Early and mid-term treatment, but the water will still contain some heavy metal copper, long-term pollution discharge will still cause serious pollution to the local water environment
