Preferably, it adds after mixing ferrimanganic composite material with other conventional fillers in the step 3) to aeration and biological
Additional fillers are used as in filter tank, iron carbon composite accounts for the 30%-50% of total filler quality.
The present invention is to the discarded of the enriched microorganism and organic matter generated in biological aerated filter advanced treatment process
Granular activated carbon carries out hydrothermal carbonization processing, and suitable molysite and manganese substance, rejected particles are added during hydrothermal carbonization
The compound base high-performance adsorbent material of ferrimanganic is made by hydrothermal carbonization in active carbon.In addition, a small amount of hydro-thermal liquid that water-heat process generates
It is back to wastewater treatment front end.The microcellular structure and quantity of active carbon can be changed in hydro-thermal process, makes discarded granular activated carbon water
Hot recycling, a large amount of microorganisms and organic matter for being enriched in rejected particles activated carbon surface are carbonized in water-heat process forms biology
The removal ability of pollutant can be improved in charcoal, the iron and manganese substance of composite material, and the hydrothermal product of acquisition is added again to exposure
Gas biofilter carries out advanced treating as filler, to dyeing waste water, realizes that the dystopy of filter tank disused stuffing material is spontaneous.
Compared with prior art, the invention has the following advantages:
(1) this method can realize that the dystopy of biological carbon filter disused stuffing material is spontaneous, change the microcellular structure and number of active carbon
It measures, the compound adsorbing material of ferrimanganic can be made by adding iron powder and manganese substance in water-heat process, and granular activated carbon that will be discarded provides
Sourceization utilizes；
(2) this method has fully considered the organic matter and enriched microorganism of granular activated carbon adsorption, by its same particle
Active carbon carries out hydro-thermal process jointly, in addition to the regeneration for realizing granular activated carbon, organic matter and enrichment to adsorption
