[交流] 汉译英 一段话

藻经浓度梯度驯养后,能够适应较高浓度含盐废水。废水不经灭菌处理,利用微生物和藻类之间的共生作用构建菌-藻混养体系。当废水稀释比为0.95,光照度为1200Lux,培养温度为34℃,二氧化碳浓度为6.3%时,废水处理效果最佳,此时废水COD降低30.03%,蛋白质含量降低10.15%,盐含量降低22.56%,pH值从4.56上升到10.02。培养后的废水仍然达不到排放标准,藻液离心分离后,将未驯化的藻种接种到离心液中继续培养,二次培养废水COD降到100mg/ml以下,达到排放标准。通过对培养条件的优化,蛋白核小球藻的细胞干重可达到1.25g/L,脂肪酸含量可以达到44.36%,可用于生物燃料的生产原料。
      目前本课题处于初步研究阶段,废水稀释比例比较大,这会造成水资源浪费,使处理设施庞大、投资增加、运行费用提高。现在高盐废水处理主要偏向于不脱盐、不稀释直接进行生物处理。因此,本课题下阶段的研究将选择更耐盐且脂肪酸含量更高的藻种来处理该药厂废水。

lgae via a concentration gradient, can adapt to domesticate with high salt wastewater. Wastewater without antiseptic processing, using microorganism and algae between symbiotic algae bacteria - any role construction system. When wastewater dilution ratio was 0.95 light for 1200Lux, incubation temperature for 34 ℃ concentration of carbon dioxide is 6.3%, wastewater treatment, when wastewater best effect 30.03%, protein content COD reduce 10.15%, reducing salt content low 22.56%, pH value from 4.56 rise to 10.02. After incubation of wastewater discharge standard, still can not reach the algae liquid centrifugal separation, will not domesticated by inoculation to centrifugal fluid continue to cultivate, second training wastewater COD to 100mg/ml below, meets emission standard. Through cultivation condition optimizing, protein nuclear chlorella cells dry weight can achieve 1.25 g/L, fatty acids can achieve 44.36%, ?
