摘要
对某厂硫酸卷曲霉素废水进行预处理试验，为水处理工程设计提供参考。选择混凝·气浮-水解酸化工艺组合作为预处理工艺，试验表明，依某厂硫酸卷曲霉素生产废水特征，以PAC为混凝剂、PAM为助凝剂，投药量分别为100和5mg／L条件下，混凝．气浮单元的COD、BOD；和ss去除率分别在42．6％～48．7％、25．5％～40．8％和84．6％～92．6％之间；在水解酸化单元接种厌氧污泥，可以大大缩短污泥驯化时间，用经过14d驯化时间的污泥处理气浮单元出水，HRT为16h时，该单元的COD、BOD，去除率分别在8．4％～33．8％和5．0％～19．5％之间；气浮单元、水解酸化单元均提高了出水的可生化性。将混凝．气浮单元与水解酸化单元联合作为硫酸卷曲霉素生产废水的生化处理的前处理措施是可行的。
A pretreatment process consisted of flocculation-flotation-hydrolysis acidification units for capreomycin sulfate wastewater before biochemical treatment cell was planned, the full-scale test showed that based on the wastewater discharge features, the COD, BOD5, SS removal rates of the flocculation-flotation unit were 42.6% - 48. 7% , 25. 5% - 40. 8% , 84. 6% - 92. 6% respectively under doses of 100 mg/L of PAC and 5 mg/L of PAM which were used as a flocculants and aid flocculants separately. In hydrolysis acidification unit, the inoculation of anaerobic sludge greatly shortened the acclimation time to about 15 d,with 14 d acclimation and 16 h of the HRT for the effluent from flotation cell, the removal rates of COD and BOD5 of the unit were 8.4% - 33.8% and 5.0% - 19.5% respectively. Both of the two ceils enhanced the wastewater biodegradability to a certain extent. The results indicated that the union of the two cells is practicable to improve effects of the followed main biochemical disposal cell.
