Effect of Carbonaceous Materials Prepared from Various Solid Wastes on Degradation of Nonylphenol
In order to explore the effect of carbonaceous materials(CMs)on the adsorption and degradation of hydrophobic organic pollutants(HOCs),the effect of adding CMs from various solid wastes on the biodegradation of nonylphenol(NP)was studied by calculating the change of NP concentration and relative degradation rate.The results showed that CMs prepared from plant solid wastes(including rice straws and bamboos)had the most obvious promotion effect on the degradation of NP,especially bamboo charcoal,followed by the CM prepared from livestock solid wastes(chicken manure),the CMs prepared from industrial solid wastes was the worst,especially sludge-based biochar.Among nine kinds of CMs,their effects on the degradation of NP varied with the increase of the addition amount.With the increase of the dosage,the promotion effects of bamboo charcoals(PBP and PBC)on the degradation of NP were increased gradually,while the effects of CMs prepared from industrial solid wastes such as sludge-based biochar were inhibited.With the rest of CMs,there was a proper dosage during the degradation process,which promoted the microbial degradation.
