active biomass 中文意思是什麼
active biomass
解釋
活生物質-
Biosorption is a process that utilizes inexpensive active / dead biomass to sequester heavy metals and is particularly useful for the removal of contaminants from industrial effluents. compared with conventional methods such as ion exchange and precipitation with lime, the biosorption process offers the advantages of low operating cost, minimization of the volume of chemical and biological sludge to be disposed of, high efficiency in detoxifying very dilute effluents
生物吸附技術是環境領域近年來迅速發展起來的處理工業污染廢水的新技術，它以各種生物（菌類或藻類）吸附廢水中的重金屬離子，具有吸附容量大，選擇性強，效率高，消耗少，並能有效的處理含低濃度重金屬離子廢水等優點。 -
Based on the above conclusions about anti - erosive vegetation structure, the paper expounds the implication of anti - erosive vegetation by pointing out the fault of its current definitions, and it is considered that anti - erosive vegetation should aim at protecting soil from erosion and fixing active sands in the eroded areas, ground space fully occupied by plants, in general with close structure, especially with outstanding coverage close to ground by organic matter ( litter and / or biomass )
在上述結論的基礎上，本文通過指出現有防蝕植被定義的缺陷，論述了其涵義，認為防蝕植被應當是在侵蝕地區，以防止土壤侵蝕或以固沙為目的，植物充分佔據地面空間，一般具緊密結構，或者顯著具有有機體（枯落物以及生物量）貼地面覆蓋特徵的植被。 -
Standard test method for total active biomass in cooling tower waters kool kount assay ; kka
冷卻塔水中總活性生物體的標準試驗方法 -
With the increase of exposure time, the antioxidative ability of spirodela polyhiza dereased, sod and ap activities were induced, and asa content of treated plants were always lower than those of control plants, but the proline ( pro ) contents in treated plants increased. these factors would break the balance of the metabolism of ros and the active oxygen accumulation in leafy thallus of spirodela polyhiza could be the result, the membrane lipid peroxidation was accelerated ( mda content increased ), ultra - microstructure of chloroplast was damaged, photosynthetic capacity dereased, biomass ( dry weight ) reduced
實驗研究結果如下： （ 1 ） uv - b輻射處理后前2天，紫萍超氧化物歧化酶（ sod ）和抗壞血酸過氧化物酶（ ap ）等抗氧化酶系統有不同程度的升高，隨著uv - b處理時間的延長，紫萍體內抗氧化保護系統能力下降， sod和ap的活性下降，並且非酶類抗氧化物質抗壞血酸（ asa ）含量一直低於對照組，而脯氨酸（ pro ）的含量則一直在升高。 -
The removal efficiency of organic pollutant mainly depends on the active biomass of biofilm in the biological pretreatment of drinking water
摘要飲用水生物預處理過程中，生物膜上存活的活性生物量是有機污染物去除的基礎。 -
With the increase of temperature and biomass, nh4 + and no3 - in the surface water were largely consumed and decreased as a result ; while organic n and particle p increased as the enhancement of suspending biological particles. no2 - in the surface water increased with temperature as nitrifying bacteria became active
隨著氣溫升高和河流表層生物量的增大，表層水nh _ 4 ~ + 、 no _ 3 ~ -因大量消耗而降低；有機氮和顆粒態磷含量因生物顆粒的增加而加大； no _ 2 ~ -也會因硝化細菌活動的加劇而增加。 -
( 4 ) the active material is small in the biomass, but it participates in almost all biochemical reaction. meanwhile the experiment shows that the activity of biofilm is lower in low temperature than in normal temperature
（ 4 ）生物膜中的活性物質雖然在生物膜總量中的比例很小，但是正是這些活性物質擔負著所有生物化學反應進行的任務，試驗表明低溫時生物膜的活性較常溫低很多。
