[求助]
煩勞牛人看一下這幾句英語(yǔ)翻譯哪里有問(wèn)題，翻譯板塊人太少了，看看語(yǔ)法和結(jié)構(gòu)也行。BB

在好氧反應(yīng)器中，將海泥通過(guò)海水和營(yíng)養(yǎng)物質(zhì)培養(yǎng)成新型的活性污泥，在處理含鹽廢水時(shí)有較好的活性和沉降性能，對(duì)這種新型的活性污泥我們稱其為海洋活性污泥。 Some sea mud had been fed in aerobic reactor by natural seawater with nutrients to become activated sludge, we named it marine activated sludge. 通過(guò)10周的培養(yǎng)，海泥的污泥體積指數(shù)（SVI）從最初的19升高到70mL/g，對(duì)有機(jī)廢水處理12h后高錳酸鹽指數(shù)（CODMn）降解率達(dá)到90%，氨氮降解率達(dá)到45%。在污泥培養(yǎng)時(shí)，營(yíng)養(yǎng)物質(zhì)投加頻率為一日一次最有利于污泥的培養(yǎng)，又葡萄糖比淀粉更有利于污泥的培養(yǎng)。 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. 對(duì)于含鹽有機(jī)廢水的處理，海洋活性污泥也比傳統(tǒng)活性污泥有優(yōu)勢(shì)，甚至對(duì)于含鹽量6%的高鹽有機(jī)廢水，處理12h后能達(dá)到高錳酸鹽指數(shù)（CODMn）降解率達(dá)為70%，氨氮降解率達(dá)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. 當(dāng)NaCl濃度高于6%，海洋活性污泥仍具有一定的活性，但仍能觀察到明顯的抑制作用。此外海洋活性污泥具有比傳統(tǒng)活性污泥更強(qiáng)的鹽度變化抗性，甚至在低鹽度下鹽濃度變化時(shí)，海洋活性污泥的氨氮降解穩(wěn)定性也優(yōu)于傳統(tǒng)活性污泥。 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. |
