Abstract: By the method of artificial simulation in laboratory, and with water spinach (Ipomoea aquatic), loach (Misgurus anguillicaudatus), and a kind of pseudomonad (Rhodopseudomonas palustris)as the engineering species, a composite bioremediation system of aquatic economic plant aquatic animal microorganism was constructed to improve the water quality of sewage. The biomass of I. aquatic and M. anguillicaudatus in the system and the water quality indices were investigated. Within the 23 days experimental period, the nutrient concentrations in the sewage decreased significantly, with the removal rates of NH4+-N, NO3--N, TP, and CODMn being 96.5%, 82.2%, 53.2%, and 24.5%, respectively. Meanwhile, the biomass of I. aquatic and M. guillicaudatus was averagely increased by 31.2% and 6.1%, respectively. All the results suggested that this composite bioremediation model had good economic and environmental benefits.
Key words: moving sand dune, species distribution pattern, interspecific correlation, allometric growth.
