摘要：

采用曝气微电解-絮凝工艺预处理含嘧啶的高浓度制药废水，考察了进水pH值、HRT、曝气强度、温度、絮凝剂种类等因素对COD去除率的影响。结果表明，当废水的进水COD浓度为484 568 mg/L时，曝气微电解的最佳参数是：进水pH值为3、HRT为4.7 h、曝气强度为88.2 m3/（m2·h）、温度为30 ℃，此时去除率达70%以上，B/C值由原来的0.09提高到0.32左右，可生化性大大提高。

Abstract:

The technique of aerated micro-electrolysis and flocculation was employed to process high concentrated pyrimidine wastewater. The effects of the pH value of influent water, Hydraulic Retention Time (HRT), aeration intensity, temperature and flocculation type on the removal rate of COD were investigated. Results show that, when the COD concentration in the influent water is 484 568 mg/L, the optimal processing parameters of the aerated microelectrolysis are pH value 3 of the influent water, HRT 4.7 h, aeration intensity 88.2 m³/(m²·h), temperature 30 ℃. Under such condition, the COD removal rate was over 70%, the B/C value was increased from 0.09 to about 0.32, and the biodegradable capability was greatly increased.

Key words: water treatment, aerated microelectrolysis, flocculation, pyrimidine wastewater, biodegradable ability
