The invention discloses a preparation method of a compound bacterium agent for degrading phosphorus and belongs to the field of preparation of phosphorous reducing bacterium agents. According to the method, common activated sludge is used as a matrix for culture of activated sludge strains, active bio-enzymes mainly containing protease, lipase and cellulose are added in a culture medium manner during strain culture, so that active bio-enzymes combine and react with active microorganisms, a preservative chemical agent is added for separation and curing of the active strains when the activity of active microorganism strains and the active enzymes is cultured to the optimal state, and the activity is sealed up for safekeeping. The mechanism and activity of the active microorganisms and the active enzymes cannot be damaged during separation and curing, the activity can be recovered quickly when the strains of the active microorganisms and the active enzymes are dissolved and released in water again, and the strains can be quickly combined in other active microorganisms to grow and reproduce. The initial debugging time of biological treatment of activated sludge can be shortened and the nitrogen and phosphorus removal effect can be realized quickly.

The invention relates to a poly-catalyzed iron carbon micro-electrode filler adopting rare earth tailings as raw materials and a preparation method and application thereof. The iron carbon micro-electrode filler is prepared from rare earth tailings, limonite, coke, adhesives and a pore forming agent, wherein the mass ratio of rare earth tailings to limonite to coke is (30-35):(30-35):(30-40), andthe ratio of Fe to C is larger than or equal to 80%; the adhesive adopts kaolin, and the consumption of the adhesive is 20-30% the total mass of the rare earth tailings and the coke; the pore formingagent adopts activated carbon, and the consumption is 5-12% the total mass of the rare earth tailings and the coke. The filler can be effectively used for the wastewater treatment process, and particularly used for difficultly biodegradable printing and dyeing wastewater treatment with the high chromaticity and the low B/C ratio. The micro-electrode filter is prepared by adopting rare earth tailings as raw materials, solid waste recycling is achieved, the filter can be effectively used for treating high-concentration organic wastewater, the purposes of treating wastes with processes of wastesagainst one another and recycling wastes are achieved, and the dual purposes are achieved at the same time.
