| Abstract | Totally 77 kinds of volatile organic compounds (VOCs) in inlet/outlet wastewater of 10 typical enterprises in Hangzhou City were determined by headspace-gas chromatography-mass spectrometry, then the discharge characteristics of VOCs were analyzed, and the monitoring results were evaluated. The results indicated that 22 kinds of VOCs were detected in inlet wastewater, the range of VOCs concentrations was 7-3.39 x 10(6) microg x L(-1), while 14 kinds of VOCs were detected in outlet wastewater, the range of VOCs concentrations was 16- 6.82 x 10(4) microg x L(-1). The concentrations of VOCs in inlet/outlet wastewater of flavors and fragrances manufacturing enterprises were much higher than those of other industries. When using the third class discharge standard of "integrated wastewater discharge standard" (GB 8978-1996) as the evaluation criteria, the toluene concentration detected in outlet wastewater of enterprise 1 was 2.45 x 10(3), microg x L(-1), which exceeded the standard limit. In addition. When the discharge multimedia environmental goals (DMEG(WH)) of VOCs in water was used as the evaluation criteria, the concentrations of n-butyl alcohol, isopropyl alcohol, acetone in outlet wastewater of enterprise 3 exceeded their respective discharge multimedia environmental goals. |
