Embodiment 1

[0021] This embodiment 1 provides an adsorbent for treating lead-containing wastewater. 130 parts of rape stalks are dried and pulverized, stirred for 3 minutes; 20 parts of water are added, and stirred for 3 minutes;

[0022] Add 4 parts of carbendazim, 18 parts of triisocyanuric acid ester, 22 parts of medical stone, 50 parts of polyaluminum chloride, and stir for 15 minutes; continue to add 20 parts of water, and add 20 parts of Ca(OH) 2 , and the adsorbent can be obtained after stirring and mixing evenly.

[0023] This embodiment makes full use of natural raw material plant stalks, avoids indiscriminate burning of plant stalks, can avoid environmental pollution while increasing the added value of straws, and can effectively treat lead-containing wastewater.

Embodiment 2

[0025] This embodiment 2 provides an adsorbent for treating lead-containing wastewater. 150 parts of rape stalks are dried and pulverized, stirred for 4 minutes; 25 parts of water are added, and stirred for 5 minutes;

[0026] Add 3 parts of carbendazim, 20 parts of triisocyanuric acid ester, 20 parts of medical stone, 45 parts of polyaluminum chloride, and stir for 10 minutes; continue to add 25 parts of water, and add 45 parts of Ca(OH) 2 , and the adsorbent can be obtained after stirring and mixing evenly.

Embodiment 3

[0028] This embodiment 3 provides an adsorbent for treating lead-containing wastewater. 120 parts of rape stalks are dried and pulverized, stirred for 2 minutes; 15 parts of water are added, and stirred for 2 minutes;

[0029] Add 5 parts of carbendazim, 15 parts of triisocyanuric acid ester, 20 parts of medical stone, 40 parts of polyaluminum chloride, and stir for 10 minutes; continue to add 15 parts of water, and add 30 parts of Ca(OH) 2 , and the adsorbent can be obtained after stirring and mixing evenly.

Abstract

The invention provides an adsorption agent for treatment of lead-containing wastewater and a preparation method thereof. The adsorption agent includes a plant straw crushed material, polyaryl polymethylene isocyanate, carbendazim, a pH regulator, triisocyanuric acid ester, medical stone, polymerized aluminum chloride and water. The adsorption agent for treatment of the lead-containing wastewater can make full use of the natural raw material plant straw, avoids a phenomenon of plant straw arbitrary burning, can improve the straw added value while avoiding environmental pollution, and can effectively treat the lead-containing wastewater; the preparation method of the adsorption agent for treatment of the lead-containing wastewater is simple, can has processing completed at room temperature, and has the characteristics of energy saving and environmental protection.

Description

technical field [0001] The invention belongs to the field of environmental protection, and in particular relates to an adsorbent for treating lead-containing wastewater and a preparation method thereof. Background technique [0002] The photosynthesis of plants can provide essential energy for human beings. People often burn crop straws directly. However, the burning of straws will cause many hazards and seriously damage the environment. The main hazards are: burning straws is easy to form a large amount of smoke, resulting in reduced air visibility, The reduction of the visible range will directly affect the normal operation of civil aviation, railways, and expressways, which will easily cause traffic accidents and affect personal safety; the burning of straw can easily ignite the surrounding combustibles, leading to "burning and burning", once a wheat field fire is triggered, Often difficult to control, resulting in economic losses. Especially in the vicinity of mountain ...
