TA对印染废水处理效果的影响

Study on TA effect to treatment efficiency of dying wastewater

印染综合废水的酸析预处理效率主要受废水中对苯二甲酸 (TA)含量的影响 ,且印染综合废水酸析规律与纯 TA配制液相比较存在一定差异。分别对纯 TA配制液、印染综合废水、加 TA后的废水、酸析预处理后的废水进行好氧生化处理试验 ,研究其降解规律与去除效率。结果表明 TA属易好氧生化物质 。

The efficiency of acid precipitation pretreatment of dying wastewater is primarily affected by the ratio of TA in wastewater. By aerobic treating the following wastewater:pure TA solution, printing wastewater, printing wastewater added TA and dying wastewater with acid precipitation pretreatment, study the degradation rules and efficiency. The results of the experiments state that TA is easy to be degraded by aerobic process and can be improved the biological degradability of printing wastewater. Through acid precipitation pretreatment of the dying wastewater, B/C is decreased from 0.36 to 0.24.\;
