模拟水厂实际工艺,采用臭氧-活性炭工艺处理黄浦江原水。对比试验结果表明:预臭氧和后臭氧投加量分别为1.74和2.11 mg/L时,O3-AC工艺对CODMn的去除率在80%左右,能有效解决出厂水CODMn大于3 mg/L的问题;对色度的去除效果显著,但在未形成生物膜的情况下,对氨氮的去除效果仅在20%左右,对亚硝酸盐的去除效果不及水厂常规处理工艺。
Simulate the actual process of waterworks, the use of ozone - activated carbon process Huangpu River water. The results of the comparative experiment show that the removal rate of CODMn by O3-AC process is about 80% when the pre-ozone and post-ozone dosage are 1.74 and 2.11 mg / L respectively, which can effectively solve the problem that the output water CODMn is greater than 3 mg / L ; The chroma removal effect is significant, but in the case of not forming a biofilm, the removal efficiency of ammonia nitrogen is only about 20%, nitrite removal efficiency is less than the conventional treatment of waterworks.
