- 摘要:
- 單一環(huán)境因子對水生植物復(fù)氧能力影響較大且存在不少分歧，因此研究了環(huán)境因子（光照、溫度、pH值、鹽度）對水生植物復(fù)氧和去除污染物能力的影響。結(jié)果表明：菹草在光照強度為80%自然光（9 600 lx）條件下，復(fù)氧能力最高，OE值達到127×10-5；黑藻、浮萍、香蒲的復(fù)氧能力隨著光照強度的升高而增加。高溫不利于水生植物向水體復(fù)氧，因此在夏季高溫時，可采用機械曝氣方式向水體復(fù)氧。水生植物在中性環(huán)境中可向水體輸送較多的氧氣，在整個pH值梯度范圍（6.0~8.0）內(nèi)，沉水植物、挺水植物去除TN、TP、COD的能力較高，浮葉植物對富營養(yǎng)鹽的去除效果欠佳。水生植物復(fù)氧能力隨鹽度的升高而明顯下降，在鹽度過高區(qū)域（0.8%），黑藻、菹草、浮萍和荇菜幾乎沒有復(fù)氧能力；水生植物對水體中TN、TP和COD的去除能力隨鹽度的增加也呈下降趨勢。
- Abstract:
- The effects of environmental factors on the aquatic plants reoxygenation are complicated. The influences of environmental factors (illumination, temperature, pH, and salinity) on the ability of aquatic plants to recover oxygen and remove pollutants were studied. With 80% light intensity (9 600 lx), Potamogeton crispus showed the highest reoxygenation capacity and the OE value reached 127×10-5. The reoxygenation capacity of black algae, duckweed, and cattail increased with the increase of the light intensity. High temperature inhibited the aquatic plants from restoring DO, therefore it was recommended to utilize mechanical aeration methods under summer temperatures. Aquatic plants could transport more oxygen to the water in a neutral environment. Within the pH gradient from 6.0 to 8.0, submergent and emergent plants were more efficient in the removal of TN, TP and COD comparing to floatingleaf plants. The reoxygenation capacity of aquatic plants decreased significantly with the increase of salinity. In high salinity water (0.8%), black algae, Potamogeton crispus, duckweed, and Nymphoides peltatum barely had any reoxygenation capacity. The purification capacity of the six aquatic plants for TN, TP and COD decreased as the salinity increased.
