Abstract
  • The biological treatability of p-nitrosophenol wastewater was investigated using Sequencing Batch Reactors (SBRs). Two 2.5 1 SBRs were operated for more than six months and were fed both a raw waste and a synthetic feed. Removal of phenol was greater than 93% and soluble COD removal was 75% or greater. The inhibitory effects of the phenolic waste were partially overcome by increasing the number of treatment cycles per day. Significant loading rates were sustained throughout the study, the highest being achieved at two cycles per day. Loss of soluble COD by abiotic means was ruled out. The use of SBRs for treatment of p-nitrosophenol wastewaters will result in significant savings over present chemical oxidation processes.
