摘要
采用自制光催化氧化试验装置处理经ABR厌氧处理后的半合成抗生素制药废水。研究表明:CODcr、pH分别为823mg/L、7.23的废水,经光催化氧化处理,当废水流速200L/h、空气流速70L/h、光解时间90min时,CODcr去除率达93.1%、CODcr降至56.8mg/L。
The half-synthetic antibiotic pharmacy wastewater pretreated with ABR had treated with home-made photo catalytic oxidation apparatus. The results showed that the effluent CODcr aimed at influent CODcr=823 mg/L, pH=7.23 was reduced to 56.8 mg/L, CODcr removal rate reached 93.1%, when the velocities of wastewater flow and air flow were 200 L/h, 70 L/h, respectively, and when photo-decomposed time was 90 min
