Abstract

Twenty organic chemical substances, tetrachloroethylene, toluene, ethylbenzene, p-xylene, m-xylene, isopropyl benzene, stylene, bromobenzene, 1,3,5-trimethylbenzene, 2-chlorotoluene 1,2,4-trimethylbenzene, p-isopropyltoluene, 4-chlorotoluene, n-butylbenzene, 1,2,4-trichlorobenzene, naphthalene, tert-butylbenzene, sec-butylbenzene, phenol, isopropyl benzene hydroperoxide were isolated from untreated and treated wastewater collected at 76 companys of 9 types industry in the basin of Young San River. Their organic compounds were elucidated by Gas Chromatography/Mass Spectrometry (GC/MS) and by comparison with each standard reagents. Especially, phenol compound is detected from effluent water but not detected from plant wastewater in the chemical industry. Heavy metal, which are Cr, Mn, Cu, Zn, Cd, Pb, As, Al and Fe, are contained in the plant wastewater of all industry, Fe, Al of them is more detected than the other metals in plant wastewater. Cr, Cd, Pb, As is contained much in plant wastewater of electricity and electron, metal molding industry. Nine metals is nearely treated when plant wastewater is treated, and then the concentration of each other metals is detected below water quality standard or not detected by using AA.
