[0026] A kind of preparation method of heavy metal adsorption material of the present invention comprises the following steps:
[0027] A preparation method for a heavy metal adsorption material, characterized in that it comprises the following steps:
[0028] Step 1, peeling the straw to obtain the inner core of the straw; cutting the inner core of the straw to a small section of the inner core with a length of 2-3 cm; the straw is one of corn straw, wheat straw or sorghum straw;
[0029] Step 2, take reclaimed water, and adjust the pH to 5-7; preferably, reclaimed water is reclaimed water from domestic sewage sources,
[0030] Step 3. Soak the small section of the inner core in medium water, the soaking temperature is 25-30°C, and the soaking period is 35-40 days; when the TOC value of the soaking solution is greater than 40, filter to obtain straw humus and straw residue, straw The humic fluid is the heavy metal adsorption material.
Embodiment 1
[0032] A preparation method for a heavy metal adsorption material, characterized in that it comprises the following steps:
[0033] Step 1, peeling off the outer layer of the corn stalk to obtain the inner core of the corn stalk, and cutting the inner core of the corn stalk into 3 cm inner core segments;
[0034] Step 2, taking the water in the domestic sewage source, and adjusting the pH of the water in the domestic sewage source to 5;
[0035] Step 3. Soak the small section of the inner core in medium water. When the TOC value in the soaking solution is greater than 60, filter to obtain the straw humus solution and straw residue. The straw humus solution is the heavy metal adsorption material; the soaking temperature is 25°C Under conditions, the immersion period is 40 days.
Embodiment 2
[0037] A preparation method for a heavy metal adsorption material, characterized in that it comprises the following steps:
[0038] Step 1, peeling off the outer layer of the wheat straw to obtain the inner core of the wheat straw, and cutting the inner core of the wheat straw into small pieces of the inner core of 2.5 cm;
[0039] Step 2, taking reclaimed water from the domestic sewage source, and adjusting the pH of the reclaimed water to 6;
[0040] Step 3. Soak the small section of the inner core in reclaimed water. When the measured TOC value in the reclaimed water is greater than 50, filter to obtain the straw humus solution and straw residue. The straw humus solution is the heavy metal adsorption material; the soaking temperature is 27°C Under conditions, the immersion period is 38 days.
