不同再生水占比景观水体水质演变机制实验研究
|
摘要
以永定河(北京段)为研究对象,开展不同再生水占比景观水体连续24d的水质监测实验,监测指标包括化学需氧量、氨氮、溶解氧、pH、电导率及土壤微生物多样性等。结果分析表明:相同实验条件下永定河上游山峡段河岸带土壤微生物多样性明显好于下游沙质断流河岸带土壤,而二者混合形成的沙土有利于丰富土壤微生物多样性;高再生水占比水体对于环境更加敏感,更容易因为外部因素引起水质变化,在高温下水质恶化速率更快;根据实验所监测的多项水质指标与生态效应综合分析,静止景观水体再生水占比在超过75%以后水质持续恶化,推荐永定河实际景观河道再生水占比控制在75%以下。
Taking Yongding River(Beijing section)as the research object,we monitored the changes of water quality in landscape water bodies with different ratios of reclaimed water for 24 consecutive days.The monitoring indicators included chemical oxygen demand,ammonia nitrogen,dissolved oxygen,pH,conductivity,and soil microbial diversity.The results showed that:The microbial diversity in the upstream riparian soil of the Yongding River is significantly better than that in the downstream riparian soil.The sand formed by the combination of the two is conducive to enriching soil microbial diversity.The water body with a high ratio of reclaimed water is more sensitive to environmental changes.Its water quality is more prone to changes when influenced by external factors,and deteriorates faster at high temperature.According to the comprehensive analysis of various water quality indicators monitored by the experiment,the water quality of impounded landscape water bodies will deteriorate continuously if the ratio of reclaimed water exceeds 75%.It is recommended that the ratio of reclaimed water in Yongding River be controlled below 75%.
