Title

EFFECTS OF ORGANIC AMENDMENT ON BIOREMEDIATION OF HYDROCARBON CONTAMINATED SOIL BY COMPOSTING

Pages

  29-39

Abstract

 Soil contamination with Total PETROLEUM HYDROCARBON (TPH) from the leaking underground storage tanks (LUSTs) and its adverse effects are major problems and more important environmental concerns that we are facing today. In the present research bioremediation method was applied for the remediation of the CONTAMINATED SOIL with TPH using soil COMPOSTing with organic amendment. SEWAGE SLUDGE, COMPOST and poultry waste were added as amendments for supplementing the organic matter for COMPOSTing of the CONTAMINATED SOIL. Target contaminant of this research was the TPH-CONTAMINATED SOIL obtained from the Tehran Refinery Site. The amount of contaminant in soil was 140,000-mg/kg dry weight basis. The major objective of this research was to find the appropriate mix ratio of the organic amendments to soil for enhancing the PETROLEUM HYDROCARBONs degradation during the COMPOSTing process. The ratios of CONTAMINATED SOIL to organic amendments were 1:0.1, 1:0.3, 1:0.5, and 1:1 as wet weight basis. The degradation of TPH was significantly enhanced by the addition of these organic amendments relative to the straight soil.Degradation rates of the total PETROLEUM HYDROCARBONs (TPH) were the greatest at the ratio of 1:1 of the CONTAMINATED SOIL to the organic amendments. The first order degradation constant of TPH with Sludge was about twice TPH Soil degradation constant .The reactors were divided into two groups: MCR (Mixed COMPOSTing Reactor) and ACR (Aerated COMPOSTing Reactor). Total volatilization loss of TPH was only about 2-5 % of initial TPH Lose of TPH mainly due to the slow degradation compounds. High correlations were found among the TPH degradation rate, the amount of CO2 evolved and microbial activity. The rate of elimination for SEWAGE SLUDGE, COMPOST, poultry waste and control soil for MCR reactors are as follows: 60, 40, 30 and 25, respectively and for ACR reactors were: 63, 56, 43 and 38, respectively.
