Resumo
The study evaluated the influence of seasonality in efficiency of Trindade Wastewater Treatment Plant (WWTP), during six months,
that had dry and rainy seasons. The following variables were analyzed: flow rate, wastewater temperature, depth, HDT, pH, DO,
CND, Chla,TP, PO4
-3, NH4+, NO3-
, BOD5
20°C, COD, TSS, FSS, VSS and also climatic variables. There was no removal of COD and
TSS during the rainy season. The Principal Component Analysis (PCA) indicated that there were groupings of raw affluent and the
anaerobic lagoon, and between facultative pond and maturation, in other words, there was spatial variation. ACP also indicated
that raw affluent in Nov/10 and Dec/10 formed a separate group, because these months suffered enough dilution characterizing it
as another environment. The influence of seasonality caused increase in concentrations of some variables and decrease in others,
which has influenced the efficiency of ponds.
