分段进水A/O工艺处理城市污水的试验研究

Laboratorial Research on the Treatment of A/O Process to Municipal Wastewater

针对目前国内外对分段进水工艺的研究只是停留在过程仿真或对模拟生活污水的研究阶段,通过采用城市污水对该工艺的运行特性与优化控制进行了较详尽的基础研究.通过3个阶段试验,比较了不同ρ(C)/ρ(N)对提高分段进水A/O工艺脱氮效率的影响,对优化控制运行该工艺提供了理论基础.

The multi-feed multilevel A/O biological nitrogen removal process has distinct advantages in nitrogen removal.Currently,the researches all over the world on the multi-feed biological nitrogen removal process are limited only on the process emulation and synthetic-sized wastewater.By using real-wastewater simulate with the multi-feed process,the operational characteristics and the optimal controlled operation were more comp retentively investigated with 3 steps each with different ρ(C)/ρ(N) ratios.
