摘要
利用铁炭微电解塔对某污水处理厂抗生素类混合工业废水进行预处理。控制进水流量约为2.0 t/d,进水B/C为0.05~0.09,COD浓度165~550 mg/L,TP浓度3.3~16.4 mg/L,经微电解处理后,B/C值提高到0.22,COD和TP的平均去除率约为28%和71%。当气液比为3：1,p H值为3时,对COD的去除效果最好。而TP的去除率受初始TP浓度、气液比和p H值变化的影响小。
The iron-carbon micro-electrolysis tower is used to pre-treat antibiotic-based mixed industrial wastewater in a sewage treatment plant.Under the condition of water flow about 2.0t / d,B / C value 0.05~ 0.09,COD concentration 550 ~ 165 mg / L,TP concentration 3.3 ~ 16.4 mg / L,it is found that after micro-electrolysis treatment B / C value increases to 0.22 and the mean removal efficiency of COD and TP is about 28%and 71%,respectively.When the gas-liquid ratio is 3：1 and the p H is 3,the removal efficiency of COD is optimal.However,the removal efficiency of TP is hardly affected by the initial TP concentration,gas-liquid ratio and p H value.
