Study on the removal ability of five species of Zingiberaceae to sewage
Journal Title: 广东农业科学 - Year 2018, Vol 45, Issue 3
Abstract
"In order to study the sewage purification ability of five species of Zingiberaceae，including Hedychium coronarium，Alpinia. spp，Hedychium. sp，H. qingchengense，and H. flavescens. The dynamic changes of nitrogen（ N），phosphorus（ P） and ammonia nitrogen（ NH4 +-N） in water purification process were analyzed. The results showed that the 5 experimental plants could not only survive in the experimental sewage environment，but also absorbed 97.36%-98.03% ammonia nitrogen（ NH4 +-N） in the sewage. The growth physiology of H. coronarium was better than that of other experimental plants. The removal rate of nitrogen（ N） and phosphorus（ P） in sewage of H. coronarium was 85.44% and 87.08%，respectively，Hedychium. sp. was 80.31% and 85.33% respectively. Therefore，they are better at removing nitrogen and phosphorus from sewage. The chemical oxygen demand（ COD） in the sewage of the five experimental plants were reduced，and effectively improved the dissolved oxygen content（ DO）."
