9、你们的酶是如何得到的？
答：我们的酶大量地从活的细菌中提取的单氧酶和双氧酶的粗混合物。
Q. Where do your enzymes come from?
A. Our enzymes are a crude mixture of monooxygenase and dioxygenase compounds “harvested” from live bacterial cultures.
10、酶是成活的细胞吗？
答：不。酶是蛋白质，是从活细胞中提取出来的。
Q. Are the enzymes living cells?
A. No. Enzymes are proteins that have been extracted from living cells.
11、什么是溶解氧就地处理？
答：溶解氧就地处理是一种复杂的生物修复方法。它将本公司专利生物产品和增氧技术相结合，迅速地、稳定地对污染的土壤和地下水进行就地生物清除。
Q. What is Dissolved Oxygen In situ Treatment?
A. Dissolved Oxygen In situ Treatment (DO-IT™) is a complicated bioremediation approach that utilizes ETEC’s proprietary biological products and oxygenation technology for rapid, consistent biological cleanup of soil and groundwater.
12、DO-IT技术如何应用？
答：应用DO-IT技术，将生物加强的产品和增氧水喷射到被污染的地下水表面。最好这个过程包括注射/抽提系统的密闭回路。也可以用新鲜水注射。注射点包括竖井和/或水平渠道。
Q. How is DO-IT™ applied?
A. The DO-IT™ technology is applied by injecting biologically enhanced and oxygenated water into the subsurfac. Preferably, the process will include a closed-loop injection/extraction system, but fresh water injection may also be used. Delivery points include vertical wells and/or horizontal trenches.
13、DO-IT技术可以用于LNAPL游离产品回收吗？
答：是的。DO-IT技术可以用于LNAPL游离产品回收。我们强烈的推荐持续回收LNAPL，而且DO-IT技术的独特的增氧和生物加强工艺可以处理土壤和地下水中的LNAPL。
Q. Does the DO-IT™ technology work with free product (LNAPL)?
A. Yes, the DO-IT™ does work with LNAPL. We strongly encourage continued LNAPL recovery efforts, but the unique oxygenation and biological enhancement process of the DO-IT™ technology will treat the LNAPL in the soil and groundwater.
14、为什么氧对于生物修复很重要？
答：在有氧生物降解过程中，氧是电子受体。原先的有机污染物（石油烃类）被转化为二氧化碳和水。
Q. Why is oxygen important for bioremediation?
A. In aerobic bioremediation, oxygen is the electron acceptor, and is required for the oxidation-reduction reactions that transform the organic contaminants (petroleum hydrocarbons) to carbon dioxide and water.
