摘要:
以西安市某再生水厂出水为水源,通过模拟景观水体中藻生物膜的生长,探索水体固相介质接触面藻生物膜的滋生、时空变化及组成特征.试验结果表明,不同时间和不同位置藻生物膜中的藻数量、藻种分布及物质组成存在明显差异.单位面积藻生物膜中的碳氮磷含量、藻数量、EPS含量及铁锰含量随时间逐渐增加,在试验运行第65天时达到最大值,然后随脱落降低; 试验过程中,中层藻生物膜中的TCOD、TN和TP的平均含量、藻数量、EPS含量均明显高于上层和下层的对应值,藻生物膜的这种层间差异可能主要与光照有关.总之,粘附于固相介质表面的藻生物膜,可吸收利用再生水中的营养物、吸附富集再生水中的铁锰等金属离子,一定程度上可缓解再生水补给的景观水体富营养化和重金属污染问题,但需通过主动控制的方式以避免其引起水体景观效应降低的负面影响.
Abstract:
This study explored the growth, temporal and spatial variation and composition characteristics of algae biofilm on the surface of solid medium formed in a simulated landscape water supplied with reclaimed water. Results showed that an obvious difference existed in the algae number, algae species distribution and the composition in the algae biofilm at different time and location. The number of algae, EPS content, carbon, nitrogen, phosphorus content, iron and manganese content in the algae biofilm of per unit area increased gradually with time to the maximum value on the 65th day, and then decreased due to sloughing. In addition, during the experiment, the average content of TCOD, TN and TP, algae number and EPS in the algae biofilm of the middle layer was significantly higher than that in the upper layer and lower layer, which may be attributed to illumination factor. In brief, the algae biofilm formed in the landscape water can absorb and enrich the nutrients and some heavy metals from the reclaimed water, which may alleviate the eutrophication and heavy metal pollution when the landscape water was supplied with the reclaimed water to a certain extent. However, some proactive measures should be taken to control the negative effect to landscape of algae biofilm when the reclaimed water is adopted.
