| Popis: | The ecological fiber is a new water treatment material that is processed by simulating the shape of wild water-borne plant. In recent years it has been applied broadly in sewerage treatment for its following advantages: big specific surface area, high capacity in removing organic matter, good microbiological adhesiveness, variable pore sizes, wonderful performance in preventing jamming, flexibility in operation and management, etc. Ceramic padding has high porosity and moderate density which is highly favorable to the growth of microorganisms. This paper discussed treating the micro-polluted water by the combination of oxidation pond and constructed wetland. The results show that some indexes of the treated water reached or exceeded band 3 national water quality standards. These indexes include TN (total nitrogen), TP (total phosphorus), TDP (total dissolved phosphorus), CODCr and so on. The research results can provide scientific basis for project design. |
