plot also clearly shows the advantage of the pretreatment
of molasses with P. decumbens previous to
its anaerobic digestion. For a given value of the organic
loading removal rate, the HRT decreased considerably
when the molasses are previously fermented. In order to
establish a more rigorous comparison, the time used in
the pre-treatment (4 days) has been added to the HRT
of the pre-treated molasses, obtaining a curve located in
an intermediate position (Fig. 5). It is apparent that,
even under these circumstances, the previous statement
continues being valid. Therefore, the time necessary for
digesting a given organic load, in the case of using a
combined aerobic
/anaerobic treatment, is always lower
than that necessary to anaerobically treat the waste. On
the other hand, the performance of the reactor processing
untreated molasses starts to become destabilized for
OLR values of 5.5 g COD per l day, which does not
happen when the wastewater has been pre-treated, since
the reactor admits loading rates of up to 7.5 g COD per l
day without destabilization symptoms appreciat

is duidelik plot toon ook die voordeel van die behandeling
van Melasse met P. decumbens vorige om
sy anaërobiese vertering. Vir 'n gegewe waarde van die Organiese
Verwydering laai koers, die HRT aansienlik afgeneem
toe die voorheen Gefermenteerde Melasse is. Ten einde
'n meer streng vergelyking, die tyd wat in vestig
die pre-behandeling (4 dae) is bygevoeg om die HRT
van die pre-behandel Melasse, die verkryging van 'n kurwe geleë in
'n Intermediêre posisie (Fig. 5). Dit is duidelik dat,
selfs onder hierdie omstandighede, die vorige verklaring
wese voort Valid. Daarom is die tyd wat nodig is vir
die vertering n Gegewe Organiese Load, in die geval van die gebruik van 'n
gekombineerde aerobiese? / Anaërobiese Behandeling, is altyd Laer
as wat nodig is om anaërobies Behandel die afval. Op
die ander kant, die prestasie van die Reactor Processing
onbehandelde Melasse begin raak gedestabiliseer vir
OLR waardes van 5,5 G COD per L Day, wat nie
gebeur wanneer die afvalwater is pre-behandel, aangesien
die Reactor erken laai pryse van tot. G 7.5 COD per L
