摘要: 在实验室内利用人工模拟方法,选择水蕹菜(Ipomoea aquatica)、泥鳅(Misgurus anguillicaudatus)、沼泽红假单胞菌(Rhodopseudomonas palustris)为工程物种,构建一套水生经济植物-水生动物-微生物复合生物修复系统进行污水修复,研究该系统中动植物生物量及水质指标的变化。结果表明,在23 d的实验周期中,水体铵态氮(NH4+-N)下降96.5%,硝态氮(NO3--N)下降82.2%,总磷(TP)下降53.2%,化学需氧量(CODMn)下降24.5%。水蕹菜平均增重31.2%,泥鳅平均增重6.1%。这种复合的生物修复模式具有较好的经济效益与环境效益。

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.
