Investigation components of leachate of municipal solid waste (case study: compost plant of Isfahan city)

The leachate produced of solid waste in uncontrolled landfills can cause many impacts on the environment and human health. In the present study، the samples of leachate of compost plant in Isfahan city were sampled in the winter of 2010. Physicochemical parameters including: pH، EC، phosphate، sulfate، biological oxygen demand (BOD)، chemical oxygen demand (COD)، total solid (TS)، total dissolved solid (TDS)، and total suspended solid (TSS) were measured using standard methods and HACK DR 2800. High level of phosphate (624. 88)، sulfate (1955. 55)، BOD (32300)، COD (68000)، TS (86500) TDS (55900)، TSS (31600)، pH (5. 3) and EC (12. 9) on the basis of mg/l for all of the parameters except pH and EC was observed. Potential of pollution leachate of compost plant in Isfahan considered to leachate pollution index (LPI (. Leachate Pollution Index (LPI) for Isfahan of leachate was 54. 65. This result showed that leachate produced of solid waste of compost plant in Isfahan high potential have for pollution of the surrounding land and water by the leachate.
