Paper Title:
Remediation of City River Water by Combining Submerged Macrophyte and Bioenergizer
  Abstract

The eutrophication of water in an urban river was treated by combining two submerged aquatic plants Elodea nuttallii and Potamogeton crispus with a biological growth-promoting agent Bio-energizer (BE) on a pilot scale. The results showed that the two submerged plants could remove CODCr effectively and steadily, with a removal rate of 58% and 52.3% respectively. All experimental treatments were effective at removing TN, TP, NH4+-N, NO3+-N, but the treatment in which BE was added at the lower concentration (from 1 to 3 ml/m3) was better than that at the higher concentration (from 5 to 10 ml/m3). Elodea nuttallii produced the best treatment efficiency when 1 ml/m3 BE was added to the experimental water. The rate of removal of TP and TN was 71.0%, and 72.4% within one week while that in the control group was 50% and 51% respectively. The number of bacteria changed during the different stages of the experiment.
