Pollution Characterisytics of Stench from Wastewater Treatment System on Penicillin Production
Abstract:
With portable gas chromatography - mass spectrometry (GC - MS) each unit tested penicillin wastewater treatment system of volatile organic compounds (VOCs) from gas collection pipe. The results show that there are 29 pollutants in gas, including sulfur-containing compounds (90.37%). Large volume concentration H2S (383 ppm), isopropyl mercaptan (30,432 ppb) and acetone (16,024 ppb); H2S (766,000 times), isopropyl mercaptan (40576 times), methyl mercaptan (150 times) beyond their olfactory threshold; H2S (383 times) beyond the TWA threshold. Each unit stench in the sum of the pollutant concentration is range of 47 ~ 2103 ppm. In waste water treatment system, anaerobic treatment unit stench is highest.
