In the present embodiment, before sewage enters, close water outlet 2, at sewage, enter the wetland bed of artificial wet land system and rise to after flooding slag unit 4 and furfural dregs unit 5 and stop into water until water level; After 36～72h, slag and furfural dregs are fully reacted and make furfural dregs modification.
The principle of work that the present invention produces above-mentioned technique effect is:
Because slag belongs to alkalescence, gather materials, wherein contained free ca, magnesium oxide react and can be converted into oxyhydroxide with water or moisture, can cause water pollution once again, and cannot normally plant wetland plant, have affected its applying in artificial swamp.Furfural dregs is owing to being hydrolyzed through high-temperature sulfuric acid boiling, and cellulosic reticulated structure and intramolecular hydroxyl are substantially destroyed, and adsorptive power weakens.And in furfural dregs, also contain a small amount of acids, be applied to the danger that sewage disposal also has secondary pollution.
In the present invention, the alkalescence of slag can be eased by the acidity neutralization with furfural dregs, and in slag, contained calcium and magnesium oxides reacts the oxyhydroxide producing with water, just can be applicable to the modification of furfural dregs.So through the abundant reaction of the two, furfural dregs recovers high adsorptive power through modification, the alkalescence of slag also can be innoxious through neutralizing.Therefore, slag-furfural dregs mixed-matrix can be used as a kind of high-quality and efficient dephosphorization artificial swamp substrate combination.
