Determination of Sulfur Containing Odoruos Compounds in Night Soil Treatment Plant

초록

Odor-causing substances in Night Soil Treatmet Plant(NSTP) may be broadly classified as either inorganic gases or organic gases or organic vapors. The inorganic gases usually aries as a result of biological activity in the collection and treatment system. Likewise, the organic vapors often arise from biological activity but may result from diret additions of waste chemicals from industry. The principal odors of an organic nature arise from the anaerobic decomposition of compounds containing nitrogen and sulfur. These offenders include mercaptans, sulfides, indoles, skatoles, amines and various other nitergen and sulfur-bearing organics. However, the paper is presented only for sulfurcontaining compounds. The speific objectives of this study are to : identify chemically the characteristics and measure the concentration of the S-containing odors compounds in NSTR, evaluate effectiveness of several practical odor control process.
