Response of partial nitrification/anammox granular sludge to bio-treated wastewater

Partial nitrification/anammox (PNA) is an innovative environmental biotechnology for energy-effective removal of nitrogen from wastewater. The resistance of PNA system to many unfavorable environments after the formation of microbial community is significantly vulnerable, which can be an important indicator for the contaminated wastewater.

短程硝化-厌氧氨氧化（Partial nitrification/anammox, PNA）是一种创新性的环境生物技术，可实现污水中氮的高效节能脱除。该系统在微生物群落形成后，对多种不利环境的抗性仍显著偏弱，这一特性可作为受污染废水的重要指示指标。
