To demonstrate the effectiveness of a novel two-stage system coupling hydrolytic acidification with algal microcosms for the treatment of acrylonitrile butadiene styrene (ABS) resin-manufacturing wastewater.
After hydrolytic acidification, the BOD/COD ratio increased from 0.22 to 0.56, showing improved biodegradability of the wastewater. Coupled with hydrolytic acidification, the algal microcosms showed excellent capability of in-depth removal of COD, NH-N and phosphorus with removal rates 83, 100, and 89%, respectively, and aromatic pollutants, including benzene, were almost completely removed. The biomass concentration of Chlorella sp. increased from 5 × 10 to 2.1 × 10 cells/ml after wastewater treatment.
This two-stage coupling system achieved deep cleaning of the benzene-containing petrochemical wastewater while producing greater algae biomass resources at low cost.
证明一种新型的两级系统(将水解酸化与藻类微宇宙相结合)用于处理丙烯腈丁二烯苯乙烯(ABS)树脂制造废水的有效性。
水解酸化后,生化需氧量/化学需氧量(BOD/COD)比值从0.22提高到0.56,表明废水的生物降解性得到改善。与水解酸化相结合,藻类微宇宙显示出对化学需氧量(COD)、氨氮(NH-N)和磷的深度去除能力优异,去除率分别为83%、100%和89%,包括苯在内的芳香族污染物几乎被完全去除。废水处理后,小球藻的生物量浓度从5×10增加到2.1×10细胞/毫升。
这种两级耦合系统实现了含苯石化废水的深度净化,同时以低成本产生了更多的藻类生物质资源。
