摘要:In order to evaluate the wastewater treatment plant ( WWTP ) effluent using the parameters indicators of salinity to assess the suitability of wastewater fo r irrigation, the sampling campaigns were conducted between February 2008 and December 2009. Temperature, pH, calcium, magnesium, sodium, potassium, chlorides, bicarbonates, electrical conductivity, sodium adsorption of ratio, magnesium adsorption ratio an d sodium soluble percentage . The test results presented in this work showed that these effluents ha ve temperatures reaching 28.7° C. The pH oscillates between neutrality and basicity. Chlorides, sodium, potassium, calcium, magnesium and bicarbonates h ave me dian levels of 950.1, 57.3, 29.6, 131.6, 24.9 and 1053.2 mg/ L. The m ean values of electrical conductivity of the sodium adsorption ratio (SAR) of soluble sodium percentage (SSP) and the magnesium adsorption ratio (MAR) are respectively 2340 μ Scm - 1 , 5.4, 52.1 and 36.9%. The sodium adsorption ratio and electrical conductivity showed that wastewater irrigated at the market - garden of Sebkha oscillates between class C3S1 (high salinity and excellent low hazard alkalization) and C4S1 (very high salinity and the excellent low hazards alkalization).
