采用臭氧处理北京市高碑店污水处理厂二沉池出水,就臭氧对二沉池出水的氧化特性进行了研究.结果表明,臭氧对二沉池出水中的COD、色度、UV_(254)均有较好的去除效果,但对TOC的去除效果较差.试验条件下,臭氧的最佳投加量为10 mg/L、最佳接触时间为15 min,此时对COD的去除率为19.12%,去除单位COD的臭氧投加量为1.79 mg;对色度的去除率为58.59%,去除单位色度的臭氧投加量为1.46 mg;对UV_(254)的去除率为39.57%,去除0.001 cm~(-1)吸光度的臭氧投加量为2.82 mg;TOC/UV_(254)提高到140.29,可生化性提高了1.59倍.

The oxidation characteristics of ozone in treatment of the secondary effluent from Beijing Gaobeidian Wastewater Treatment Plant were studied.The results show that ozone has a higher removal efficiency of COD, color and UV_(254), but a lower removal efficiency of TOC.When the optimal ozone dos-age is 10 mg/L, and the optimal contact time is 15 min, the removal rates of COD, color and UV_(254) are 19.12% with 1.79 ms (O_3)/ms (COD), 58.59% with 1.46 mg (O_3)/time (color) and 39.57% with 2.82 ms (O_3)/0.001 cm~(-1) ;TOC/UV_(254) is up to 140.29, and the biodegradability is increased by 1.59 times.
