Abstract: |
This invention discloses natural cobbles as seepage biological bed filler for polluted river treatment and technology for purifying polluted river. The natural cobbles are mechanically processed into appropriate particles with sizes of 8-15 cm. The natural cobbles as the filler have such advantages as stable structure and high surface smoothness thus is suitable for washing the deposited biomembrane after the seepage biological bed is operated for a while. Besides, the filler has large particle sizes, thus is difficult for blockage and suitable for installation at the front end of the seepage biological bed. The filler is especially suitable for polluted river with large water quality fluctuation and high SS content. And the filler also has such advantage as abundant wide raw materials. |
