[0025] example 1
[0026] Take 91.0% iron filings (with a particle size of 2-4mm) as the matrix, 2% manganese dioxide, 0.01% platinum, 0.02% palladium, 0.5% copper oxide, 1.5% nickel oxide, 0.27% cobalt oxide and 0.7% oxide Zinc is the initiator, and the 4-6mm particle electrode made of 4% sodium carboxymethyl cellulose as the binder is the working electrode; the three-dimensional electrode is composed of graphite and polyester non-woven membrane as the feed electrode. reactor. At 0.3m 3 The removal rate of 100mg / l phenol solution is 92% when treated with an air flow rate of 20 volts / h for 60 minutes. The removal rate is 95% for 500mg / l chloral solution treated for 30 minutes.
Example
[0027] Example 2
[0028] With 90% carbon as the matrix, 2.0% manganese dioxide, 1.0% copper oxide, 1.25% nickel oxide, 0.22% cobalt oxide, 1.5% zinc oxide, 0.01% platinum and 0.02% palladium as initiators, with 4% A particle electrode with a particle size of 4-6mm made of sodium carboxymethyl cellulose as a binder is used as a working electrode; a three-dimensional electrode reactor with graphite and polyester non-woven membrane composite as a feed electrode. At 0.16m 3 Under the air flow rate of 20 volts, the 100 mg / l NaCN solution is treated for 30 minutes, and the CN - The removal rate reached 97%. The removal rate of the chloral solution reached 95% for 30 minutes.
