摘要
由于邻苯二甲酸酯类化合物的广泛应用,对环境造成了巨大的影响,因此对其的降解性研究刻不容缓。选取邻苯二甲酸酯类中的一种化合物——邻苯二甲酸二辛酯作为受试物,运用好氧生物降解方法,把驯养后的污水处理厂的活性污泥对其进行降解试验,通过对pH值和温度的调节,研究温度在15℃～45℃,pH值在5.0～9.0时邻苯二甲酸二辛酯(DOP)的降解情况,结果表明,好氧生物降解DOP的适宜温度为30℃～35℃,适宜pH值为8.0。
As phthalate esters are extensively applied to the environment caused a huge influence, Therefore, they study the degradation delay. I phthalate esters selection of a compound Di - n - octyl phthalate as subjects, use aerobic biodegradation methods to domesticate the sewage treatment plant activated sludge its degradation, Based on pH and temperature regulation, the study temperature 45~C to 15%, pH value of 9.0 - 5.0 at the Di - n - octyl phthalate （DOP） the degradation of the results showed that Aerobic biodegradation DOP appropriate temperature 35℃ to 30℃ , suitable for pH8. 0.
