水禾和粉绿狐尾藻对生活污水净化效果研究

A Study on the Purification Effect of Hygroryza Aristata and Myriophyllum Aquaticum on Domestic Sewage

以水禾(Hygroryza aristata)和粉绿狐尾藻(Myriophyllum aquaticum)为研究对象,分析不同培养方式对水禾和粉绿狐尾藻生长与生活污水净化效果的影响。结果表明,两种植物在生活污水中均能生长,且两种单独培养生长状况好于两种混合种植;对生活污水净化效果:粉绿狐尾藻单独培养>混合培养>水禾单独培养;生活污水经三种处理后,水体pH均有所下降,水体溶解氧含量均有所上升。

This paper takes Hygroryza aristata and Myriophyllum aquaticum as the research objects,and analyzes the effects of different cultivation methods on the growth of Hygroryza aristata and Myriophyllum aquaticum and the purification effect of domestic sewage.The results show that both plants can grow in domestic sewage,and the growth conditions of the two single cultures are better than the two mixed cultivation;the purification effect of domestic sewage on Myriophyllum aquaticum single culture>mixed culture>Hygroryza aristata single culture;After three types of wastewater treatment,the pH of the water body has decreased,and the dissolved content of the water body has increased.
