摘要
Abstract
An aquatics combination system composed of Bischofia javanica, Hygrophila salicifolia, Vallisneria na-tans, Macropodus opercularis, Cipangopaludina Cahayensi and biomass char was applied to the treatment of eu-trophic garden scenic waters. The growth status of aquatics in this system and the aquatics’ effect of eliminating lar-vae and wiggler as well as the purification effect for TN, TP, COD, NH+4-N, and NO-2-N in the water body were examined. Results showed that no larvae or wiggler was found in the aquatics combination system which enjoyed a good growth status and a satisfactory effect of removing pollutants. The removal rate of TN, TP, COD, NH+4-N, and NO-2-N reached 64.4%, 49.5%, 65.7%, 73.8% and 82.6%, respectively. The content of TN, COD and DO met the standard of surface water quality IV-level specified in national standard GB 3838—2002, and NH+4-N measured up to levelⅡ. In conclusion, each component in the aquatics combination system performs its duty, and the technology is pollution-free, hence is conducive to the sustainable water ecological restoration.关键词
