折流式活性炭纤维生物膜工艺处理景观水研究

STUDY ON POLLUTED SCENIC WATER TREATMENT BY BAFFLED ACF BIOFILM REACTOR

为提高城市景观水体的透明度、降低水体中的营养盐含量、改善水生态系统恢复的生境条件,研究了折流式活性炭纤维生物膜工艺处理景观水体效果。结果表明,在折流状态下,温度为10～28℃、pH为6.8～7.4、HRT为3h情况下,系统对COD、NH3-N、TP和浊度去除率分别达到了82%、67%、45.3%和79.4%。出水COD为14.8mg·L-1,NH3-N和TP的质量浓度分别为1.02和0.063mg·L-1,浊度为7NTU。

The Baffled ACF Biofilm Reactor was carried out to treat scenic water and the aim was improving the water habitat by increasing the transparency and reducing the concentration of N and P. The results showed that in the condition of water baffled-running, the temperature of water is 10- 28 ℃, pH is controlled between 6.8-7.4, HRT is fixed to 3 h, COD, NH3-N, TP and turbidity removal rate could be 82%,67%,45.3% and 79.4% respectively. COD,NH3-N,TP and turbidity concentrations in the down stream were reduced to 14.8 mg·L^-1,1.02 mg·L^-1,0.063mg·L^-1 and 7 NTU respectively.
