Embodiment 1
[0029] Embodiment 1: a kind of method of processing electroless nickel plating waste liquid by iron series catalyst, specifically comprises:
[0030] Step 1: Preparation of carrier
[0031] a. Separately crush diatomite, fly ash, perlite, phyllite, and biological straw, and pass through a 200-mesh sieve; wherein, the biological straw is specifically rice straw;
[0032] b. According to parts by weight, 45 parts of diatomite, 20 parts of fly ash, 15 parts of perlite, 13 parts of phyllite, and 8 parts of biological straw are put into the mixing equipment to obtain mixed raw materials, and then add the volume of mixed raw materials The ratio of 1:5 deionized water is fully stirred to obtain the mixed aggregate;
[0033] c. Then the mixed aggregate is aged for 30 hours; the specific aging steps are: control the temperature at 35°C, control the ventilation rate at 15L / min, and pass air into it for oxidation for 3h; control the temperature at 30°C, and age for 5h; then control Agi...

[0042] a. Diatomite, fly ash, perlite, phyllite, and biological straw are respectively crushed and passed through a 200-mesh sieve; wherein, the biological straw is specifically wheat straw;
[0043] b. According to parts by weight, 50 parts of diatomite, 25 parts of fly ash, 20 parts of perlite, 18 parts of phyllite, and 11 parts of biological straw are put into the mixing equipment to obtain mixed raw materials, and then add the volume of mixed raw materials The deionized water with a ratio of 1:7 is fully stirred to obtain the mixed aggregate;
[0044] c. Then, the mixed aggregate is aged for 30 hours; the specific aging steps are: control the temperature at 40°C, control the ventilation rate at 16L / min and pass air in for oxidation for 3h; control the temperature ...
Embodiment 3
[0051] Embodiment 3: different from embodiment 1: a kind of method of processing electroless nickel plating waste liquid by iron series catalyst, specifically comprises:
[0052] Step 1: Preparation of carrier
[0053] a. Diatomite, fly ash, perlite, phyllite, and biological straw are respectively crushed and passed through a 200-mesh sieve; wherein, the biological straw is specifically corn stalk;
[0054] b. According to parts by weight, 60 parts of diatomite, 30 parts of fly ash, 25 parts of perlite, 20 parts of phyllite, and 12 parts of biological straw are put into the mixing equipment to obtain mixed raw materials, and then add the volume of mixed raw materials The deionized water with a ratio of 1:8 is fully stirred to obtain the mixed aggregate;
[0055] c. Then, the mixed aggregate is aged for 36 hours; the specific aging steps are: control the temperature at 45°C, control the ventilation rate at 18L / min and pass air into it for oxidation for 3h; control the temperat...
