摘要

氮素污染是水体富营养化的主要诱因之一

反硝化技术是氮素污染控制的有效手段。采用模拟废水

研究了反硝化分段组合式反应器(CAR)的脱氮除碳性能。实验结果表明

CAR具有很高的容积效能

在进水NO3--N浓度为964.7 mg·L-1、水力停留时间为0.86 h条件下

硝氮去除速率(NRR)为26.8 kg·(m3·d)-1

COD去除速率(CRR)为93.76 kg·(m3·d)-1

NRR高于文献报道的最高值

CRR也达到文献报道的领先水平。CAR具有良好的运行稳定性

在反应器的效能上升阶段和效能稳定阶段

出水基质浓度的变异系数比和极差分别小于9.85和9.07

出水pH的相对标准差小于1。CAR运行性能出众的原因是它能持留浓度高(MLVSS高于17 g·L-1)、活性强(最大比活性为1.573 g NO3--N·(g VSS)-1·d-1)的颗粒污泥。

Abstract

Pollution of nitrogen compounds is one of the main factors that lead to eutrophication of water bodies

and biological denitrification has become an effective technology for control of nitrogen pollution.The performance of denitrifying compartmentalized anoxic reactor(CAR) was investigated with synthetic wastewater.The results showed that CAR is a high-rate reactor for nitrate removal.When influent nitrate concentration was 964.7 mg稬-1

hydraulic retention time was 0.86 h

the nitrate removal rate(NRR) and COD removal rate(CRR) reached as high as 26.8 kg?(m3穌)-1 and 93.76 kg?(m3穌)-1

respectively

which all were at the top level reported in the literature.During the operation

CAR's performance was stability.In both efficiency-elevation phase and efficiency-stationary phase

relative variation coefficient and relative range of effluent nitrate are less than 9.85 and 9.07

respectively.At the same time

the relative standard deviation of effluent pH is less than 1.The good performance of CAR could be ascribed to high biomass concentration(more than 17 g稬-1(MLVSS)) and high specific activity(more than 1.57 g NO3--N?(g VSS)-1穌-1).
