Paper Title:
Construction and Application of Suspending Combination Ecological Filter Bed
  Abstract

A new kind of suspending combination ecological filter bed was constructed, which took floating baskets as basic units and took flyash cenospheres and attapulgite clay ultra light filter material as loading material. It integrated plant absorption, filter material adsorption with biofilm colonization to purify wastewater. Experiment showed that by the use of filter bed, TP, TN and COD can be removed effectively. Three kinds of plants, including green vegetables, spinach and American-four-season-green grass were cultivated in the filter bed and grew better than those planted in soils. Germination rate and speed of growth were faster than the controlled group. The application of filter bed didn't need land occupation and civil engineering construction. Meanwhile, it can restore the polluted water, reduce the operation costs and fulfill the recycling of eutrophia water.
