Abstract

Abstract: The purification effect of slow rate land treatment system (SR-LTS) on organic pollutants in wastewater and the residual rate of organic pollutants in soil are studied in this papter. It's shown that the sYstem has a good purifying effect on organic pollutants, most of the organic pollutants in wastewater being not detected in effluent and some priority organic pollutants in it being significantly decreased, among which, the concentrations of benzene, chlorobenzcne, 1,2-dichlorobenzene and 1,4-dichlorobenzene, phenol, dibutyl-phthalate and γ-666 are much lower than the recommended quality standard of surface water, The removal efficiency for most priority organic pollutants is 95-100%, and their residual rate in soil is 0-3%.

Key words: Land treatment system, Organic pollutant, Purification effect
