[交流] 帮忙看一下几句话的英文翻译。谢谢！水处理类。帮忙改一下语法和结构。BB

同样的翻译，还有BB来领：

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. Furthermore, sludge fed once a day had the highest biodegrability. For carbon source to sludge, dextrose was better than starch in cultivation.

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%。
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.

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。
