抗生素废水碱回收与生化处理试验研究

为克服抗生素废水难以生化处理的难题，采用废碱液回收利用和生物强化处理的技术手段对废水进行了资源化小试研究。结果显示，经碱液回收后出水的COD、SS、硫酸盐和含盐量分别由13 925、45 700、417和29 900 mg/L降到了2 400、86、25和402 mg/L，色度也由6 000倍降到了5倍；经与综合污水混合后生化强化处理，出水COD、色度和硫酸盐的平均去除率分别达到了91%、84%和96.5%，处理效果理想，资源化技术处理废水可盈利54.19元/t，具有较好的经济性，值得推广应用。

Study on sodium hydroxide reclaim and biochemical treatment of antibiotic wastewater

The measurement of reclamation of waste sodium hydroxide and bioaugmentation technology were used to resolve the difficult problem of antibiotic wastewater treatment. The result showed that COD, SS, SO2-4 and salinity of outflow were reduced from inflows of 13 925, 45 700, 417 and 29 900 mg/L to outflows of 2 400, 86, 25 and 402 mg/L respectively, while the coloration decreased from 6 000 times to 5 times. After bioaugmentation treatment, the removal rates of COD, coloration and SO^2-₄ reached to 91%, 84% and 96.5% respectively. The resource-reuse treatment of wastewater can gain 54.19 yuan/t,thus the technique can be recommended for application.
