摘要： PCT No. PCT/NL92/00047 Sec. 371 Date Nov. 14, 1994 Sec. 102(e) Date Nov. 14, 1994 PCT Filed Mar. 11, 1992 PCT Pub. No. WO93/18394 PCT Pub. Date Sep. 16, 1993.An in situ probe failure detection method for probes which deliver an electric signal on account of a change of the concentration of a substance to be measured. An example of such a probe failure may be caused by, for example, fouling of the membrane as the relative change in signal may be interpreted as a change in the concentration of the substance to be measured. More particularly, the method involves detecting the need for calibrating probes, which probes deliver an electric signal on account of a change of the concentration of a substance to be measured, characterized by: (a) subjecting the probe to a stepwise change of the concentration of the substance to be measured; (b) calculating the value of the probe response time constant tc of the obtained measurement curve with the help of the following main equation (1): tcdy/dt=-y+ alpha 0+ alpha 1t wherein t=time (time), tc=probe response time constant (time), y=substrate probe signal (mass volume-1), alpha 0=substrate concentration at start of response (mass volume-1), alpha 1=rate of change of substrate concentration (mass volume-1 time-1), and (c) comparing the calculated tc values of at least two different measurements with each other, and in case the calculated tc values do not match, calibrating the probe.

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.
