同样的翻译，还有BB来领： http://muchong.com/bbs/viewthread.php?tid=3941690&fpage=1 摘 要 在好氧反应器中，将海泥通过海水和营养物质培养成新型的活性污泥，在处理含盐废水时有较好的活性和沉降性能，对这种新型的活性污泥我们称其为海洋活性污泥。通过10周的培养，海泥的污泥体积指数（SVI）从最初的19升高到70mL/g，对有机废水处理12h后高锰酸盐指数（CODMn）降解率达到90%，氨氮降解率达到45%。在污泥培养时，营养物质投加频率为一日一次最有利于污泥的培养，又葡萄糖比淀粉更有利于污泥的培养。对于含盐有机废水的处理，海洋活性污泥也比传统活性污泥有优势，甚至对于含盐量6%的高盐有机废水，处理12h后能达到高锰酸盐指数（CODMn）降解率达为70%，氨氮降解率达到30%。当NaCl浓度高于6%，海洋活性污泥仍具有一定的活性，但仍能观察到明显的抑制作用。此外海洋活性污泥具有比传统活性污泥更强的盐度变化抗性，甚至在低盐度下盐浓度变化时，海洋活性污泥的氨氮降解稳定性也优于传统活性污泥。 Abstract Some sea mud had been fed in aerobic reactor by natural seawater with nutrients to become activated sludge, we named it marine activated sludge. After ten-week cultivation, its Sludge Volume Index (SVI) increased from 19 to 70 mL/g, while CODMn degradation rate peaked 90% and degradation rate of ammonia nitrogen reached 45% after 12-hour reaction. Furthermore, sludge fed once a day had the highest biodegrability. For carbon source to sludge, dextrose was better than starch in cultivation. We also found that marine activated sludge had a stronger biodegrability in treating saline wastewater and a better stability against salinity shift than the conventional activated sludge. The CODMn degradation rate was over 70% and degradation rate of ammonia nitrogen was over 30% after 12-hour reaction while the salinity was under 6%, which presented applied values of saline wastewater treatment. However, an important degree of biological activity inhibition was observed while the salinity was above 6%. And the marine activated sludge has a higher resistance to salinity variation, even when the salinity is low. |

分开来看看： 在好氧反应器中，将海泥通过海水和营养物质培养成新型的活性污泥，在处理含盐废水时有较好的活性和沉降性能，对这种新型的活性污泥我们称其为海洋活性污泥。 Some sea mud had been fed in aerobic reactor by natural seawater with nutrients to become activated sludge, we named it marine activated sludge. 通过10周的培养，海泥的污泥体积指数（SVI）从最初的19升高到70mL/g，对有机废水处理12h后高锰酸盐指数（CODMn）降解率达到90%，氨氮降解率达到45%。在污泥培养时，营养物质投加频率为一日一次最有利于污泥的培养，又葡萄糖比淀粉更有利于污泥的培养。 After ten-week cultivation, its Sludge Volume Index (SVI) increased from 19 to 70 mL/g, while CODMn degradation rate peaked 90% and degradation rate of ammonia nitrogen reached 45% after 12-hour reaction.

已解决。论文已被录取， 改为： Some sea mud can be filled in aerobic reactor with natural seawater and nutrients to become activated sludge. It performs good activity in treating saline wastewater and we name it marine activated sludge. After a ten-weeks long cultivation, the Sludge Volume Index (SVI) increases from 19 mL/g to 70 mL/g, while CODMn degradation rate peaks 90% and degradation rate of ammonia nitrogen reaches 45% after 12-hour reaction. Furthermore, feeding sludge once a day has the highest biodegrability. And dextrose is better than starch as a carbon source for cultivation. Also, marine activated sludge has a stronger biodegrability in treating saline wastewater and a better stability against salinity shift than the conventional activated sludge. The CODMn degradation rate is over 70% and degradation rate of ammonia nitrogen is over 30% after 12-hour reaction in the case that the salinity was under 6%, both of which present applied values of saline wastewater treatment. However, an obvious biological activity inhibition is observed in the case that the salinity rate is above 6%. Further, the marine activated sludge has a higher resistance to salinity variation. Even in low salinity, marine activated sludge’s stability of the degradation rate of ammonia nitrogen overmatches conventional activated sludge. 就行了 |
