The country has 15% of the world's global 'biological capacity' -- the capacity to produce useful biological materials and to absorb waste -- compared with about 20% for the U. S.
Year after year, faster and faster, consumption outpaces the biologicalcapacity of our planet.
年复一年，消耗速度越来越快，超过了地球的生态承载力。

This results in a higher treatment capacity and permits a more economical design for the biological treatment step and the subsequent clarification and disinfection steps.
这会使处理能力更高级，同时在生物处理阶段、后续的二沉池和消毒阶段允许更加经济的设计方案。

Because of its special cell wall structure, high capacity of heavy metal-enrichment, and easy to desorption, algae has been considered as an ideal biological adsorbent.
