摘要
在焦化废水处理的小试中,进行了水解酸化提高焦化废水可生化性的动力学分析。焦化废水经水解酸化预处理后,可生化性得到了改善,后续好氧活性污泥处理系统动力学半速度常数Ks从常规活性污泥法的101.998下降到77.724,最大比降解速度K从0.00224上升到0.00353,BOD5/CODCr比值从0.27～0.29提高至0.32～0.39。
In the small test of the treatment of coking wastewater, the dynamic analysis on the biochemical ability of the coking wastewater through the hydrol ytic acidification was made. After the pre-treatment of the hydrolytic acidific ation, the bio-chemical ability of the coking wastewater was improved, the dyna mic half speed constant Ks of the subsequent aerobic activated sludge treatment system was reduced from 101.998 of the routine activated sludge treating method to 77.724, the maximum specific degradation speed K was increased from 0.002 24 to 0.003 53, and the ratio of BOD5/CODCr was increased from 0.27～0.29 to 0.32～ 0.39.
