利用填充床放电等离子体反应器抑制铜绿微囊藻生长,实验主要考察了放电处理前后藻液丙二醛(Malondialdehyde
MDA)含量、细胞膜通透性以及溶液溶解性有机碳(Dissolved Organic Carbon
DOC)含量的变化,分析放电灭活铜绿微囊藻的原因.结果发现:处理样MDA含量均比空白样的高,但二者相差的差值逐渐下降;处理当天,处理40 min和60 min样品的细胞电解质外渗率分别为7130%和8061%,远大于空白样的5650%.而后随着放置培养时间的增加,电解质外渗率先升高后下降,但一直都高于空白样的;处理40 min和60 min当天藻样的DOC含量均较空白样高,伴随着处理后放置培养时间的增加,处理40 min和60 min藻液的DOC含量略有下降,而空白样的DOC含量增加明显,从604 mg/L增加到1067 mg/L.
The growth inhibition of M.aeruginosa was investigated in the packed-bed plasma reactor from the aspects of the content of malonaldehyde (MDA)
electrolysis on the membrane permeability
and changes in dissolved organic carbon (DOC) to analyze the mechanism of the inactivation of M.aeruginosa. The results show that the content of MDA of the test sample is higher than that of the control sample
but the difference between the test and control sample decreases. The electrolysis on the membrane permeability is 7130% and 8061%
respectively after 40 min and 60 min treatment
which are higher than those of the control sample (56% and 50%). In the storage period
the electrolysis on the membrane permeability increases rapidly
and then decreases
but it is still higher than that of the control sample. The content of DOC of the test sample is higher than that of the control sample immediately after 40 min and 60 min treatment. Then
the content of the test sample decreases while that of the control sample obviously increases from 604 mg/L to 1067 mg/L.
