摘要

This paper presents the test results of various rapid biochemical oxygen demand (BOD)rninstruments to establish online respirometry for process control at wastewater treatment plantsrnduring events of industrial waste discharges. Several methods to measure soluble BOD throughrnbacterial respiration (biosensors, and biomembranes reactors) have been implemented by variousrninstrument manufacturers in USA, Germany, and Japan. Respirometry can provide insight intornthe industrial waste discharge concentration in the plant’s influent by the health of the bacteriarnculture.rnBOD is generally considered by plant operators to be the most important measure of wastewaterrnstrength, but the standard laboratory procedure to measure it, the BOD5 test (Standard Methods,rn1992), is far too slow to use for process control. Faster tests for related parameters have beenrnavailable for years, such as, the chemical oxygen demand (COD) test which takes 2-3 hours, andrntotal organic carbon (TOC) which only measures the content of organic compounds, not otherrnsubstances that contribute to BOD.rnThe diurnal patterns of BOD loadings and new effluent regulations for wastewater effluent makernit desirable to monitor BOD influent concentration in real-time to allow plant operators tornrespond quickly to BOD fluctuations caused by industrial waste discharge in ways that willrnprevent process upsets.rnWe tested various presently available respirometric systems and concluded that systemsrnemploying bio-reactors using plant inflow provide the most representative behavior of plant’srnBOD influent changes within minutes. The quick response of these instruments will help tornidentify high loading of BOD (shock loadings) as it occurs to prevent any violation to the plant’srnpermit. The BIOX-1010 performance in the field including its moderate maintenance make itrnideal for application to detect shock loadings for process control.
