项目摘要
A bio-film process such as an aerobic submerged filter process using ecotechnology has an effect on the removal of algae and the purification of polluted lake water. In this process, it is thought that smaller animals will play an important role by the way filamentous microorganisms belonging to Phormidium sp., Anabaena sp., and Oscillatoria sp. appear in polluted lake water. Particularly Phormidium tenue in these filamentous algae produce musty odor which is caused by 2-methylisoborneol(2MIB). Therefore, deodorization has to be conducted in a water treatment plant especially. This study was conducted for the purpose of clarifying the feeding and decompositional capacity of P. tenue by Protozoa Trithigmostoma cucullulus having a mouth structure fitted to the predation of the filamentous algae. The results obtained from this study are as follows. 1) Sludge extract wasextremely effective as the growth factor in the growth of T. cucullulus. 2) The optimum growth temperature of T. cucullul … More us was about 20-25^゚C and it was necessary to keep an aerobic condition in existence and growth. 3) Filamentous P. tenue among some algae was the suitable food for T. cucullulus. 4) The predation speed of T. cucullulus in the case using filamentous algae as food was about 10-30mum/sec. 5) The content of chlorophyll a was extremely low in its reduction rate in the system without T. cucullulus, but markedly reduced in the system with T. cucullulus. 6)The turbidity, TOC and DOC in culture medium were markedly reduced in the system with T. cucullulus as compared without T. cucullulus. 7) Investigation the effect of bacteria and T. cucullulus on the removal of the musty odor produced by P. tenue, the removal activity of the musty odor was markedly enhanced by the predation of P. tenue by T. cucullulus compared with bacteria only. 8) T. cucullulus had high capacity for reducing 2MIB through the predation and decomposition of musty odor producing filamentous algae represented by P. tenue. TON measurement and gaschromatographic analysis confirmed that fixation of musly odor decomposing microorganisms, such as the isolated bacteria and T. cucullulus, into a contach aeration reactor could improve removing efficiency of musty odor remarkably and achieve high-order treatment water.

采用生态技术的好氧浸没式过滤工艺等生物膜工艺对藻类的去除和受污染湖水的净化具有一定的效果。在这一过程中,据认为,较小的动物将发挥重要作用的方式丝状微生物属于席藻属,鱼腥藻属、和颤藻(Oscillatoriasp.)特别是这些丝状藻类中的纤细席藻(Phormidium tenue)产生由2-甲基异麦芽糖(2 MIB)引起的霉味。因此,必须特别在水处理厂中进行预处理。本研究旨在阐明僧帽三殖口原虫(Trithigmostoma cucullulus)对细叶原甲的摄食和分解能力。僧帽三殖口原虫具有适合于捕食丝状藻类的口部结构。从这项研究中获得的结果如下。1)污泥提取物作为生长因子对T.僧帽2)T.兜形 ...更多信息 在20-25 ℃的温度下,维持好氧条件是其生存和生长的必要条件。3)在一些藻类中,细丝状藻是T.僧帽4)捕食速度也随时间的延长而加快。在使用丝状藻类作为食物的情况下,cucullulus的速度为约10- 30 μ m/sec。5)在不加T的系统中,叶绿素a含量的降低速率极低。cucullulus,但在T.僧帽6)在T. cucullulus与T.僧帽7)研究了细菌和T.结果表明,小兜螨对P. tenue产生的霉味的去除活性明显高于小兜螨,小兜螨对P. tenue产生的霉味的去除活性明显高于小兜螨。与细菌相比,只有cucullulus。8)T. cucullulus通过捕食和分解以P. tenue为代表的产生霉味的丝状藻类而具有高的还原2 MIB的能力。TON测定和气相色谱分析证实,分离的细菌和T。在接触式曝气反应器中投加小球藻,可显著提高霉味的去除效率,实现水的高效处理。少
