So, a lot of fundamental research work needed to be done, including screening Daphnia, as a biomonitor, that is sensitive to toxicant but less to environment changing so as to decrease the environmental interferences for obtaining more accurate determination results; exploring the relationship between the phototactic behavior of Daphnia and pollutants such as nitrogen, phosphate, heavy metal, hormone and pesticide, especially their mixtures; studying the effect of environmental conditions such as temperature, pH and fish kairomones on the phototactic behavior of Daphnia.

口。。。口国。国里华典翩胭角嗓国但由于缺乏有效的研究方法,致使有关研究难于开展,人们不得不忽略有害物质之间的互相作用,把有害物质共同存在情况视为单一存在。因此,研究氮、磷和重金属对水搔趋光行为的影响规律,有益于认识富营养化水体和重金属污染的土壤中污染物之间的相互作用,弄清这些污染元素共存时产生的生物和环境效应,这些研究是治理土壤和水体污染之前必须解决的重大科学问题。

Effect of inoculation with phosphate-solubilizing bacteria and soil acidification on the growth of Stylosanthes guianensis Reyan No.2

我国地表水体污染普遍严重,水环境生态质量不断恶化,影响水体正常使用功能;另外,沉积物中磷的再释放是影响水体水质的重要原因,而沉积物中的磷细菌对磷的吸收、贮存和释放在磷循环中起着极其重要的作用,为此本研究针对地表水体水质改善技术及沉积物中磷细菌作用分别进行了研究,并选择在杭州市内河进行了水质改善的技术实践,主要成果如下:(1)在室内模拟条件下,分别设置了高溶解氧7。

The artifical fillers are hung under the plant floating bed then the remedial system combined by plant and microorganism came into being. The remedial effectiveness of the system was visibly better than that of the phytoremediation alone. So when the temperature is higher the remedial system combined by plant and microorganism is the preferable remedial technique to remedy contaminated water. In autumnal end and winterly outset, the temperature is lower, the plants begin to fade and die, and the plant must be harvested lest the relict of plant should contaminate water again. At the same time the technique combined by immobilized nitrogen cycling bacteria and microorganism which already existed in the water was used to remedy contaminated water.

将人工填料悬挂于植物浮床下,形成植物和微生物相结合的修复系统,其修复效果明显好于单独植物修复技术,因此温度较高时用植物和微生物共同结合的生物修复技术修复水体污染;秋末冬初温度较低时,植物开始死亡,必须将植物收割,以免植物残体造成二次污染,此时用固定化氮循环细菌和水体中原有微生物相结合的技术来修复水体的污染。
