| 摘 要： | 对羟基苯甘氨酸废水属于高浓度难处理有机废水,针对生产工艺的特点,采取了废水分类处理的新路线.试验结果表明,高浓度废水经过物化处理后,苯酚的回收率达到95%,每日回收硫酸铵约6t;低浓度废水采取水解酸化-接触氧化-沉淀-活性炭吸附工艺是可行的,COD、BOD5、NH3-N及挥发酚的总去除率分别为95.6%、94.6%、93.7%和99%. |
| 关 键 词： | 对羟基苯甘氨酸 高浓度有机废水 蒸发 水解酸化 生物接触氧化 |

| Abstract: | D-p-hydroxyphenylglycine wastewater is a high concentration organic wastewater difficult to be treated. In accordance with the technological features of D-p-hydroxyphenylglycine production, this experiment adopts a new route for wastewater classification. Experiment shows that the rate of phenol recovery reaches 95% after physico-chemical treatment of high concentration wastewater ; about six tons of ammonium sulphate is extracted daily. It is feasible to process the low-concentration organic wastewater by means of hydrolysis acidification-biological contact oxidation-precipitation-activated carbon absorption. The total removal rates of COD, BOD5, NH3-N and the volatile phenol are 95.6% , 94.6% , 93.7% , and 99% respectively. |
| Keywords: | D-p-hydroxyphenylglycine high concentration organic wastewater evaporation hydrolytic acidification biological contact oxidation |
