| 中文摘要 |
| 利用测定微生物呼吸耗氧量的方法,从生物氧化程度出发,研究易降解有机物对氯代芳香化合物生物降解性能的影响。结果表明,易降解有机物的存在有利于受试物的降解,生物氧化率的增加值与所投易降解BOD5浓度的关系具有类似米-门公式的形式。易降解有机物的存在对于受试物的影响可通过最大生物氧化率增加值(ΔEmax)和达到最大生物氧化率一半时的BOD5/浓度(Kcb)值的不同来反映。最大可能生物氧化率随受试物含氯量的增高而降低。 |
| 英文摘要 |
| By measuring the respiratory oxygen consumption,a study on the effect of easily biodegradable organics on the aerobic biodegradation of chlorinated aromatic compounds was conducted.The experimental results show that the coexist of easily biodegradable organics is favorable for the biodegradation of the tested compounds and the increase of ratio of bio-oxidation (RBO) with the concentration of non-biodegradable BOD5 added nearly follows the Michaelis-Menten equation,the effect of easily biodegradable organics on the biodegradation of the tested compounds can be described through the increased value of maximum bio-oxidation ratio (ΔEmax) and the concentration of BOD5 at which half of increase value of maximum bio oxidation ratio (Kcb) was obtained.The value of maximum RBO decreases with the increase of chlorine-contained percentage. |
