摘要： PCT No. PCT/BE93/00025 Sec. 371 Date Jan. 4, 1995 Sec. 102(e) Date Jan. 4, 1995 PCT Filed May 12, 1993 PCT Pub. No. WO93/23349 PCT Pub. Date Nov. 25, 1993A method for processing a liquid nitrogen-rich organic waste product, in particular a manure product, to an aqueous fertilizer solution utilizes a biological conversion process so as to obtain a biologically stable fertilizer solution. This conversion process includes at least a nitrification step wherein nitrifiable ammonium nitrogen is converted in nitrate nitrogen and, only if the fraction to be nitrified has a too high content of nitrifiable nitrogen, a denitrification step. The fertilizer solution is separated off after the nitrification step so that it contains nitrate and only up to 150 mg NH4+-N/l at most. The fertilizer solution can be used as leaf nutrition or in a hydroponic system.

摘要： The invention relates to a method for processing manure, liquid manure and/or Kjeldahl-N containing waste water being subjected to a nitrification in an aerated reactor containing active sludge and to a denitrification in a high rate recirculation denitrification reactor (13) containing a very compact biomass capable of converting nitrate to nitrogen gas. The loading of the nitrification reactor (9) being controlled to obtain an optimal nitrification and denitrification, the effluent from the nitrification reactor (9) partially being passed to the recirculation denitrification reactor (13), adding a source of carbon to the effluent to be passed to the recirculation denitrification reactor (13) and passing another portion of the effluent stream from the nitrification reactor (9) to a separation step (19) to separate a sludge, the effluent from separation step (19) being passed to a discharge line denitrification reactor (37) under the addition of a carbon source if desired. The invention further relates to an apparatus constructed for this purpose.
