摘　　要：用多孔填料填充废水处理系统缺氧/好氧(A/O)工艺中的缺氧滴滤池,微生物挂摸之后构成三维的生物膜,处理可生化性差的重油裂解制气废水,不但能显著提高废水的可生物降解性,BOD5/COD从进水O.16～0.25提高到出水时的0.24～0.45,而且降低废水中的COD和氨氮分别为4.76％～44.21％和1.93％～44.20％,同时能增强缺氧池的抗冲击能力和减毒作用,有利于后续的活性污泥好氧处理。A research combined trickling filter system and active sludge aeration system was applied in the treatment of industrial wastewater from gas-generating with heavy oil. The wastewater contained both high contents of NH+4-N and mixed hydrocarbons including various PAHs. Its BOD5/COD ratio was less than 0.3 and belongs to recalcitrant, toxic wastewater. The results showed a touch-growth biofilms system was formed on the porous packing material and it played a key role in the decrease of toxicity of the influent. It could also improve the biodegradability of the wastewater.
