Hydrocarbons Emissions from a Municipal Wastewater Treatment Pilot Plant in Vienna
نویسندگان
چکیده
Hydrocarbons emissions were measured from an aeration tank of a municipal wastewater treatment pilot plant. The collected off-gas samples were characterised for C2–C7 hydrocarbons using GC-FID analytical technique while the total volatile organic compounds (TVOC) were measured using a continuous hydrocarbon gas analyser. Approximately, the estimated emission rates for 1 m3 of wastewater from this aeration tank were 5 mgC of C2–C7 hydrocarbons, and an average of 7 gC of TVOC. With exception to toluene, all other measured hydrocarbons are emitted less than 1 mgC day−1. The results support the view that a significant reduction in annual emissions of hydrocarbons from wastewater treatment plants in Vienna has taken place.

aerosols from a pilot-scale wastewater treatment plant with intermittent aeration
Atmospheric emissions from a pilot wastewater treatment plant performing aerobic and anoxic processes were investigated. The experiment was performed by sealing the whole aeration tank with an airtight cover of polyethylene in order to obtain a de"ned #ow rate of the o!-gas. By measuring concentrations in the known #ux of the o!-gas emission rates were determined. Due to the dimensions of the p...

Polycyclic aromatic hydrocarbons (PAHs) are very hazardous compounds and, owing to their lipophilicity, they can easily cross biological membranes and accumulate inside organisms, causing damage to the genetic material. The scientific interest in PAHs is related to their demonstrated or supposed genotoxicity (cancer-causing characteristics of B[alpha]Py and dB[alpha, h] first suspected in the 1...
