PP-III-76TECHNOLOGICAL ASPECTS OF WASTE WATER TREATMENTFROM ORGANIC POLLUTANTSTorosyan G. 1 , Isakov A. 1 , Kudryavtsev A. 1 , Harutyunyan S. 2 , Hovhannisyan D. 31 State Engineering University of Armenia, department of chemical technology &environmental engineering, Yerevan, Armenia, e-mail: gagiktorosyan@seua.am2 Yerevan State Economic University Yerevan, Armenia3 Yerevan university of Architecture & Construction, Yerevan, ArmeniaIt has been investigated an adsorbtive abilities of sorbents available in RepublicArmenia, in particular H-mordenit and the activated coal made of plum stones, inrelation to organic pollutants for the purpose of device-technological design ofprocess of waste water treatment. As organic pollutants here was studied the mostknown water pollutants as aniline, phenol, toluene and malathion.Here are offered cross-step or counter-flow schemes For waste water treatmentprocess device design. At equal number of the basic devices in the consideredschemes preference it is given counter - step scheme.The researches were spent in static conditions on a laboratory rocking chair.Sorbents in quantity of 1,0 ±0.01 g brought in water solutions, volume 100 ±0.1 mlcontaining organic compounds in quantity from the maximum solubility to maximumconcentration limit for each substance. Further a mix placed on a rocking chair andsubjected to hashing during during 6h., at temperature of 20° , then test defendedwithin 24 h. Residual quantities of substances were defined by methods of UVspectroscopyand HLECh (system Water 486-detector, Water 600S - controller,Water 626-Pump, a column 250x4 mm filled microspherical silica as sorbent, speedof a stream of a mobile phase of 1 ml/mines).On the basis of the analysis of data isotherms of adsorption which have beenprocessed by means equations of Dubinin-Radushkevich, Langmuir, Friendlich havebeen constructed [1].On the basis of the received experimental and settlement data mathematicalmodels of the technological scheme of adsorbtive water treating from notedpollutants have been deduced. On superficial groups of hydro group and atoms ofoxygen of H-zeolites processes of formation of chemical bonds owing to molecularinteractions with groups of hydroxyl / for phenol/ and amino groups / for aniline /proceed.582
