Filler, relative density reaches 0.95g/cm3More than, by vacuum-sintering, with abundant microcellular structure, reactivity is strong；Phase
For traditional micro-electrolysis stuffing, when the addition of manganese-cobalt-cerium-lanthanum makes filler form micro- galvanic cell in waste water, between negative and positive the two poles of the earth
Electromotive force it is big；Rare-earth element cerium, lanthanum are typical metallic elements, and outer layer is easily lost again because their atomic radius is big
6s electronics and 5d or 4f electronics, so the chemism of rare earth element is very strong, are only second to alkali and alkaline earth metal ions element, than it
His metallic element is all active.The chemism of rare earth metal is very strong, and rare earth doped element is significantly carried to the efficiency of Fe-C micro electrolysis
, there is synergy between manganese-cobalt and cerium-lanthanum in height；
3rd, micro-electrolysis stuffing of the invention has further passed through organically-modified, and the particle voids such as diatomite increase, surface phase
To smooth, because surfactant is loaded in particle surface, while carrying out absorption exchange, bentonite clay particle duct is opened,
Space increases, adsorption effect enhancing, is more beneficial for adsorbing the organic pollution materials in waste water.
Micro-electrolysis stuffing prepared by the present invention is compared by processing dyeing waste water with commercially available oval micro-electrolysis stuffing
Compared with the premise of experimental condition identical, the effect of micro-electrolysis stuffing removal COD of the invention and colourity is more excellent, particularly color
Degree removing aspect, can reach more than 80% removal efficiency, considerably beyond the decolorizing efficiency of prior art 40-60%, obtain
Unexpected technique effect.
