| 中文摘要 |
| 采用兼氧接触工艺处理纺织印染废水,该工艺具有电耗低,耐受高pH值冲击,降低pH值,降解部分有机物,提高废水可生化性的作用。生产装置进水pH8.8-12.5,COD 1266.9mg/L,兼氧接触处理出水pH7.6-10.1,COD 894.0mg/L,COD去除率29.4%,出水经后续好氧处理,达到GB8978-88二级新扩改排放标准。 |
| 英文摘要 |
| The trial's conclusion showed that the process has the advantage oflower electricity consumption, bearinghigh pH value, degrading some part of organic material and increasing the ability of biochemistry treatment. The result of pilot project showed that the pH value achieved 7.6-10.1 and COD concentration reached 894.0mg/L in the effluent when the pH value was 8.8-12.5 and COD concentration was 1266.9mg/L in influent. The removel rate of COD was 29.4%. The effluent quality was up to the GB8978-88 National Two-Grade Effluent Standard after the continued aerobic treatment. |
