| 中文摘要 |
| 在含两级A/O和生物炭的连续运行试验装置上处理PTA废水,结果表明:进水CODcr为1101mg/L,HRT为40h,O2段和生物炭出水中残余CODcr分别为82mg/L和55mg/L,相应CODcr去除率分别为92%和95%;进水CODcr为1112mg/L,HRT为32h,O2段和生物炭出水中残余CODcr分别为86mg/L和64mg/L,其去除率分别为92%和95%;在上述试验条件下,O2段TA去除率均为93%。 |
| 英文摘要 |
| A continuously operating pilot plant consisting of a two-sarge A/O bio film system and a biological activated carbon unit was used to treat a wastewater from a fine TPA production process. It was found that when the pilot plant was operated at a hydraulic residence time (HRT) of 40 h with an influent having a CODcr concentration of 1101mg/L, then the second stage of the A/O system and the biological activated carbon unit had their effluentS with a CODcr concentration of 82 mg/L and 55 mg/L respectively, and a corresponding CODcr removal of 92% and 95%, respectively. When the pilot plant was operated at a HRT of 32 h with an influent having a CODcr concentration of 1112 mg/L, the second stage of the A/O system and the biological AC unit had their effluents with a CODcr, concentration of 86 mg/L and 64 mg/L respectively, and a corresponding CODcr removal of 92% and 95%, respectively. Under the above conditions of operation,the second stage of the A/O system had a TA (total acid) removal of 93% for both cases. |
