(Applause) We've built technology that can predict oxygen demand, and we use blockchain to track our blood system.

（掌声）我们已经建立了可以预测需氧量的技术，并且我们使用区块链来跟踪我们的血液系统。

Given the bacteriology and taking into account the chemical oxygen demand, plus we have a bit of tributyl phosphate — not a product I see very often.

考虑到细菌学和化学需氧量，再加上我们发现有一点磷酸三丁酯——这不是我经常看到的产物。

Total emissions of chemical oxygen demand and ammonia nitrogen will see an 8-percent drop, and that of oxynitride and volatile organic compounds will be reduced by more than 10% from 2020 levels, said the plan.

化学需氧量、氨氮、氮氧化物、挥发性有机物排放总量比2020年分别下降8%、8%、10%以上、10%以上。
