Treatment of coke wastewater in a sequential batch reactor (SBR) at pilot plant scale


Abstract:

Coke wastewater is a highly toxic industrial effluent which is usually treated by a combination of physico-chemical and biological treatments. With the aim of completing prior studies carried out in CSTR, in this work we studied the treatment of coke wastewater in a pilot plant equipped with a 400L stripping tank, a 350L neutralization/homogenization tank and a 6m high 1500L sequential batch reactor (SBR), controlled by a PLC. Ammonia stripping efficiencies of 96% were obtained for HRT of 66h. The biological treatment in the SBR led to removal efficiencies of 85% COD, 98% thiocyanate and 99% phenols for HRT of 115h. Final concentrations in the effluent of 1.8mg phenols/L, 5.4mg SCN/L, 206mg COD/L and 78mg N–NH4+/L were obtained.
