采用水培法研究了海洋滩涂耐盐植物海马齿(Sesuvium portu lacastrum Linn.)对海水菲污染的修复作用.结果显示,实验4d后,不种植海马齿的对照组、种植海马齿的抑菌组和不抑菌组海水中菲浓度分别从0.988、0.942和0.957mg·L-1降至0.553、0.185和0.070mg·L-1,降低了44.0%、80.4%和92.7%;与对照组相比,抑菌组(T1)和不抑菌组(T2)海水中菲的去除率分别提高了36.4%和48.7%,不抑菌组又比抑菌组高12.3%.利用差减法计算的结果显示,在与自然水体接近的不抑菌条件下,菲的非生物损失、海马齿的作用和微生物的作用,三者对海水中菲浓度降低(92.7%)的贡献分别为44.0%、36.4%和12.3%,海马齿植株内菲的积累量则仅占海水中菲减少量的2.6%.研究表明,水培海马齿可明显提高菲污染海水中菲的去除率,其中,植物与微生物共同发挥着重要的作用,但植物积累不是海马齿修复海水菲污染的主要机制.
The hydrolization method was used to study the repair effects of Sesuvium portu lacastrum Linn. On seawater phenanthrene contamination. The results showed that after 4 days of experiment, the control group without hippocampal teeth and the bacteriostasis group with hippocampal teeth And the concentration of phenanthrene in sea water of non-inhibitory group decreased from 0.988, 0.942 and 0.957 mg · L-1 to 0.553, 0.185 and 0.070 mg · L-1, respectively, decreased by 44.0%, 80.4% and 92.7% , And the removal efficiencies of phenanthrene in seawater were increased by 36.4% and 48.7% respectively in the bacteriostatic (T1) and non-bacteriostatic (T2) groups, and 12.3% in the non-bacteriostatic and inhibitory groups, respectively , The non-biological loss of phenanthrene, the action of hippocampal teeth and the action of microorganisms in the non-bacteriostatic conditions close to the natural water body contributed 44.0% and 36.4% to the decrease of the Philippine concentration in seawater (92.7%) and 12.3%, the accumulation of phenanthrene in hippocampal dentate plant accounted for only 2.6% of the decrease of Philippine in seawater.Research shows that hydroponics hippocampal dentate can obviously improve the removal rate of phenanthrene in seawater contaminated by phenanthrene, in which plants and microorganisms play together Important role, but plant accumulation is not the main mechanism of hippocampal denture repair sea water pollution.
