摘　　要：用ＰＶＡ固定化球和厌氧－好氧ＩＭＣ技术处理四环素结晶母液，结果表明：当总停留时间为厌氧２４ｈ（３５℃），好氧６ｈ时，ＣＯＤ和四环素的去除率分别为９６％。容积负荷（ＣＯＤ）２．０７ｋｇ／（ｍ３．ｄ）。较普通法容积负荷提高１６．３％，产气量提高４．５７倍。此方法具有系统运行稳定，容积负荷高，产泥量少等优点。Immobilized-- microbial -- cell (IMC)technology,a new technique for biological wastewater treatment,was used to treat a spent tetracycline liquor. The experimental results showed that the removals of both COD and tetracycline were 96% at a COD loading of 2. 07 kg/(m3. d). As compared with a conventional A/O process,there was an increase of COD loading by 16. 3% and of gas production by 4. 57 times.The IMC technology was found to have some further advantuses,including a more stable operatinn and allowing a higher pollutant loading and less sludge generation.
