A/O前置反硝化和巴氏生物脱氮工艺脱氮效率分析

DENITRIFICATION ANALYSIS OF A/O AND BARDENPHO PRE-DENITRIFICATION PROCESS

本文对A/O和巴氏脱氮工艺好氧池的NO_3^-—N去除率与污泥回流比和内回流比的关系进行了理论分析,并对工艺设计提出了建议。

The relationships between NO3 -N removal ratio, the sludge return ratio and the inner recycling ratio in the aerobic reactors of the A/O and Bardenpho denitrifi-cation systems are discussed theoretically and some suggestions to improve the techolog-ical process are proposed.
