【摘要】 本文主要研究了白腐真菌固定化技术以及固定化白腐真菌在焦化废水处理中的应用。培养和驯化了能有效降解焦化废水的白腐真菌。固定化实验结果表明：载体吸附法优于包埋法，在稻草粉末、棉花秆粉末、木屑、麦秆粉末、花生壳粉末等载体中木屑是最为理想的吸附固定载体；在常温下干燥保存木屑固定的白腐真菌操作简便、经济，易于储存和运输，保存180天后活性只降低了8.8％。固定化的白腐真菌降解焦化废水的最佳pH值为6.5，最佳温度为30℃；最佳投菌量为8.0g·L^-1；3天COD去除率可达84.89％，酚类的去除率达70.38％。结合镀铜铁内电解预处理、氨氮菌脱氮以及Fenton氧化+活性炭吸附技术，对焦化废水进行综合治理。COD、氨氮、酚类的去除率分别为98.6％、98.56％和99.04％，出水水质可达到回用要求。固定化白腐真菌降解焦化废水符合一级反应动力学，动力学模式可用lnS=Kt+lnα表示；30℃时的动力学方程为ln（COD）=-0.0265t+ln3243，反应速率常数k=0.00265h^-1。更多还原

【Abstract】 The immobilization of white rot fungi and the applications of immobilized white rot fungi to coking wastewater treatment were studied.The white rot fungi was cultivated and domesticated for coking wastewater treatment. The results of immobilization experiments indicated that the immobilized method of carrier adsorption was better than embedding. The wood chip was perfect carrier for immobilization among rice straw powder, cotton stalk powder, wood chip, wheat straw powder and groundnut shell powder. The immobilized fungi that desiccated in room temperature with a low investment and easy operation was easily to deposited, transported. And the activity debased 8.8% after 180 days deposited.For removal of the contamination in coking wastewater by the immobilized white rot fungi, the optimum pH value and temperature were 6.5 and 30℃while the optimum dose of immobilized white rot fungi was8.0 g·L^-1, respectively. The removal rate of COD and phenolic compound were 84.89% and 70.38% in 3 days. For coking wastewater comprehensive treatment, the Internal electrolysis by copper iron—Ammonia removal bacteria degradation—Immobilized white rot fungi degradation—Fenton+adsorption process was carried out, and the removal rate of COD, ammonia nitrogen and phenolic compound were98.6%、98.56% and 99.04%. The effluent quality can meet the needs of recycle.The macro-kinetic of immobilized white rot fungi removal organic in coking wastewater was followed first order kinetics, and the kinetic equation model was In S=-Kt+Inα. The kinetic equation was In（COD）=-0.0265t+In 3243 in 30℃when the reaction rate（k） was 0.0265 h^-1.更多还原
