To reduce and eliminate the hazards of pentachlorophenol (PCP) to the soil, the method of inoculating free and immobilized white rot fungi, Phanerochaete chrysosporium to PCP-polluted soils was investigated. Three parallel beakers A, B, C are adopted with the same components of soil, yard waste, straw and bran for aerated composting to degrade the PCP in soil. A was with no inoculants as control, B was added with the inoculants of immobilized P. chrysosporium, C was inoculated with non-immobilized P. chrysosporium, and additionally D contained only PCP-contaminated soils also as control. By contrastive analyses, the feasibility of applying composting to the bioremediation of the PCP-polluted soil was discussed. From the experimental results, it could be seen that the degradation rate of PCP by the immobilized fungi exceeded 50% at day 9, while that of the non-immobilized fungi achieved the same rate at day 16. However, the final degradation rates of PCP for both of them were beyond 90% at day 60 and that the rate of A was much lower than the others. The above data have shown that the degradation effect of inoculating P. chrysosporium was better than that of no inoculation, and that of the immobilized fungi was better than that of non-immobilized ones. Meanwhile, shown by all the indicators the composts of A, B and C were mature and stabilized at the end of the experiment. Therefore, the method of composting with immobilized P. chrysosporium is effective for the bioremediation of PCP-contaminated soil.
