چکیده مقاله
Fajr petrochemical company produces principle utilities for other petrochemicals and also it treats their sewage It is located in Petrochemical Economic Specific Zone at northwest of Persian Gulf and near Imam Port Burning the sludge is an option that has been chosen for industrial sewage treatment plant before disposal in hazardous waste landfills Stabilization/solidification S/S is one of the options has been widely applied for the immobilization of hazardous wastes containing heavy metals In recent studies, cement based S/S method is used for industrial and municipal incinerators ash management The objective of this study was to investigate whether incarceration oily sludge followed by stabilization/solidification could be proper option as a management method for this kind of sludge or not In this study, at the first step, oily sludge was burn in laboratory kiln and chemical and physical characteristics of incinerated ash were determined Afterwards, S/S technology was studied on ash as an option before disposal In addition, the leachability of the heavy metals was studied by using the Toxicity Characteristic Leaching Procedure TCLP TCLP test was applied on specimens with replacement of cement in varying proportions i e 0%, 5%, 15% and 25% by incinerated ash Also, heavy metals measurement was specified by inductively coupled plasma ICP Chemical and physical characteristics results show that incinerated ash has fine grained particles and it was remarkably without porosity In addition, metals leaching test results on the ash and compare with reliable standards show that Zn content in leaching test is more than allowable criteria Hence, ash was introduced a hazardous waste Nonetheless, metals leaching tests results on the stabilized specimens with cement mortar express safe disposal for this hazardous waste
