Investigation of Changes in Physico-Chemical Parameters of Composting Plant Leachate in Isfahan

Abstract

Background & Objectives: Leachate from solid waste in uncontrolled landfills can have many effects on the environment and human health. The purpose of this study was to investigate the variation of physical and chemical properties of leachate from Isfahan Compost Plant Reception Hall during time. Methods: In the present study, samples were collected from leachate of a compost plant in Isfahan for 12 months during the years in 2016 and 2017. Different physico-chemical properties including biochemical oxidation, chemical oxygenation, total soluble solids, total suspended solids, nitrate, total nitrogen, phosphorous, pH, EC, sodium, calcium and potassium, as well as concentration of 9 metallic elements of iron, lead, nickel, chromium, cadmium, magnesium, zinc, copper and manganese in the leachate were measured during the time.
