摘要

Composting of crude Oil production Sludge (OS) differently with Poultry Manure (PM) and Municipal solid Waste (MW) was carried out at John Ker Nigeria Research Site in Ikot Ekpene, Akwa Ibom State, Nigeria, to evaluate the heavy metals content of the cured composts. Each of the two compost combinations (OSPM and OSMW) was homogenously mixed and stored in jute bags using various ratios of 1:1, 1:5, 1:10 and 1:20 volume-volume basis, respectively, for six weeks. The result reveals that the content of heavy metals in the fresh oily sludge and municipal solid waste was similar, but higher than that of fresh poultry manure. Mean contents of essential nutrients such as Zn, Cu Mn and Fe in the among OSPM cured composts were; 270.8, 24.1, 339.6 and 856.5 mg kg 1 compared to 286.4, 469.9, 219.73 and 851.0 mg kg 1 in the OSMW composts, respectively. There were low mean concentrations of heavy metals such as Vi(6.72), Ni(8.67), Pb(0.004) and Cd(0.001) in the OSPM cured composts, unlike Vi(4.4), Ni(8.2), Pb(61.1) and Cd(3.20) mg kg 1, in the OSMW cured composts. The composting process created a favourable condition for the microbial degradation of the oily sludge, with heavy metals content of the cured composts influenced by the contents of these elements their fresh organic samples used.
