The Study of Biological Combination System to Remedy the Polluted River

Abstract:

As a sewage disposal system, a biological combination system of constructed wetlands and sand filters was set up to develop the technology, to improve the disposal performance, to offer the theoretical foundation and technical parameters for realizing the standardized engineering construc- tion. The results show that: 1) The system shows certain removal efficiency to CODCr, TN, NH4-N and TP, however because of the limited space on the bank, the results are not so satisfying.2) Among the aquatic plants selected on the principle of native species, Water Celery, Canna Generalis, Iris and Ranunculus Sceleratus can grow very well.3) The revetments make the DO rise by about 5~7mg/L, of which ecological board revetment has the best re-oxygenation performance.
