Leachates contain large amounts of organic matter and compounds such as ammonia-nitrogen, heavy metals, chlorinated organic and inorganic salts. Not treatment leachate migration from the landfill to surface and groundwater could be a potential source of contaminations.Various treatment leachate method include biological treatment (aerobic and anaerobic processes) and physical and chemical treatment (chemical oxidation, adsorption, chemical precipitation, coagulation/?occulation, sedimentation/?otation and air stripping) have been used to treat land?ll leachate. Moreover heavy metals are one of the most important and dangerous environmental pollutants because of accumulating in aquatic ecosystem and high toxicity characteristics. In recent years, adsorption process has taken more attention at heavy metals and pollutants treatment due to high efficiency and approximately low cost. At this among, low cost adsorbents can be considered as one of the widely-used process for the removal of heavy metals from the wastewater due to its simplicity of design, easy availability, versatility, selectivity, environmentally friendly method and high removal efficiency. The objective of this study was the adsorption of copper and chromium heavy metals and reduction of organic matter of leachate using production adsorbents from compost to form raw and treatment (300°C and 600°C). The adsorption experiments was designed using batch and column techniques, and the parameters affecting the sorption including equilibrium time, pH, initial heavy metals concentration, adsorbent amount and its particle size were investigated. Some physical, chemical and morphological properties of adsorbents were determined by thermal gravimetric analysis, fourier transform infrared spectroscopy, scanning electron microscopy, elemental analysis and experimental analysis. Adsorption kinetics studies showed that the adsorption of copper and chromium heavy metals by raw and treatment compost is rapid, as to reach equilibrium for copper adsorption was found to be 30 and 15 min for raw and 300TC sorbents, and 600TC sorbent, respectively and for chromium adsorption was 60 min. the pseudo- first order and pseudo- second order kinetic data for heavy metals sorption by three adsorbents shown that pseudo- second order model were precisely fitted. There was not significant difference (?=5%) in the percentage of copper removal with an increase of pH from 2.0 to 6.0. The optimum pH for chromium sorption by adsorbents was 3/0. The isotherms adsorption indicated that the adsorption by raw and treatment compost could be well described by Langmuir and Redlich–Peterson models for copper and Freundlich and Redlich–Peterson models for chromium adsorption. Maximum capacity of copper and chromium adsorption using adsorbents were forecast 50 and 13 mg/g by Langmuir, respectively. The percentage of copper removal increased with the increment of the sorbent amount and decrease of particle size. Copper desorption by hydrochloric acid and nitric acid were equal for 600 °C treatment compost, and to survey of adsorbents efficiency at copper adsorption at column techniques after asid transit from it, 5M nitric acid concentration were chose. The result of this stage shown that column has 70% efficiency of copper adsorption. The initial results of removal organic matter from leachate shown that adsorbents have efficiency of COD adsorption (%30). Also to survey the optimum adsorbent amount for reduction of COD from leachate by 600°C treatment compost shown that with the increment of the sorbent amount t the percentage of COD removal increased. Therefore achieved to more reduction of leachate COD to be need to more adsorbent amount that is conceivable as regards it easy availability and low cost. Moreover organic matter adsorption from wastewater shown that removal percent with raw and 600°C treatment compost from %41.2 to %58.8 were increased with to be low initial COD concentration.
