Abstract: |
This invention discloses seepage biological bed composite filler for polluted river treatment and technology for purifying polluted river. The composite filler is prepared from construction waste bricks and industrial waste ceramics as the raw materials by mechanical processing into appropriate particles and mixing. The particle sizes are within the range of 3-10 cm, and the volume ratio of waste bricks to waste ceramics is (1.5-3) : 1. The composite filler has such advantages as stable structure, high porousity and high surface roughness, thus is suitable for microbe growth. Besides, the composite filler has abundant wide raw materials, and can solve the environmental problem of soil occupation by waste bricks and waste ceramics. |
