SBR工艺是目前国内外普遍关注和研究的一种生物处理技术，本文结合污水处理中脱氮除磷这一热点，分别介绍了国内外SBR脱氮工艺、除磷工艺以及同步脱氮除磷工艺的研究进展，指出了SBR工艺在脱氮除磷方向的广阔前景。

@@@@SBR process was a bio-processing technology of common concern at home and abroad. The research progress of SBR denitrification process, dephosphorization process and synchronization nitrogen and phosphorus removal process at home and abroad were introduced. The prospect direction for SBR denitrification and phosphorus removal was point out.

以城市垃圾渗滤液为研究对象,采用脉冲式SBR工艺进行短程深度脱氮试验研究.基于理论分析,建立了进水次数对脉冲式SBR法脱氮效率的影响公式,同时应用过程控制优化工艺运行.结果表明,脉冲式SBR工艺通过短程生物脱氮途径,NH4+-N和TN的去除率分别达到95.8%和90.0%以上,最终出水NH4+-N和TN分别低于5.0,15.0mg/L.精准的过程控制是脉冲式SBR工艺短程生物脱氮实现及稳定的主要因素.随着进水次数的增加,外碳源投加量明显减少.因此,采用脉冲式SBR处理垃圾渗滤液,可实现深度脱氮和节省运行费用双重目的.

The pulsed-SBR process was used to achieve the advanced nitrogen removal via nitrite pathway from landfill leachate. The effect of feed frequency on the process characteristic of pulse-SBR was discussed theoretically and nitrogen removal efficiency formula was established. The operation of the SBR under alternating aerobic-anoxic conditions was optimized by process control. The experimental results showed that up to 95.8%NH4+-N and 90.0%TN were eliminated via nitrite from leachate in the pulsed-SBR and advanced nitrogen removal was successfully obtained. The accurate on-line process control was main factor of the achievement and stabilization of partial biological nitrogen removal. With increasing feed frequency, the external carbon source dosage decreased obviously. Therefore, the objectives of saving external carbon source dosage and achieving advanced nitrogen removal were obtained when pulsed-SBR was used to treat landfill leachate.

比较了序列间歇式活性污泥法（SBR）、生物脱氮除磷法（AAO）、生物氧化沟法3种白酒企业污水好氧处理工艺的处理效果。相对而言，AAO的处理效果略好于氧化沟和SBR工艺，因此可在AAO工艺的基础上进行改进，使其更好地应用于古井贡酒厂废水的处理，处理后的废水可以达到国家排放标准。

In this paper, the effects of three aerobic treatment methods for liquor-making wastewater including sequencing batch reactor acti-vated sludge process (SBR), anaerobic-anoxic-oxic(AAO) and oxidation ditch were compared. Comparatively, AAO had better effects than oxi-dation ditch and SBR. Therefore, we could make technical improvement of AAO for better treatment of liquor-making wastewater in Gujing Gongjiu Distillery and make the treated wastewater meet national discharge standards.

The development,working principles and characteristics of SBR process are summarized, and taking its applica-tion in a hydropower station camp sewage treatment for example. From the aspects of technology and economy , The engi-neering practice shows good effect can be received by using SBR process to treat domestic sewage. It’s suitable for popu-larization and application in hydropower station camp and other small sewage treatment.

研究采用序批式生物反应器（SBR）处理模拟含盐废水,在乙醇作为碳源的条件下,当DO为2-3 mg/L、温度为35±1℃、pH为7.5-8.5时,考察Na2SO4盐度对SBR工艺脱氮效果的影响。结果表明：SBR反应器经过30 d的驯化,活性污泥氨氮去除率高于90%;在其基础上,SBR反应器中添加Na2SO4,当Na2SO4盐度增加到12 g/L时,污泥系统的氨氮去除率降低至80%,亚硝态氮积累率达到90%。在一定盐度下可实现亚硝酸盐的积累,完成短程硝化反硝化。

A continuous experiment was carried out using sequencing batch reactor process to treat wastewater containing saline.The effect of Na2 SO4 on the denitrification was investigated when alco-hol was used as carbon source under the condition of dissolved oxygen (DO)of 2-3 mg/L,35±1 ℃and pH 7.5-8.5.The results showed that removal efficiency of ammonia nitrogen was higher than 90% after the domestication of 30 d,and then Na2 SO4 was added to the SBR system.And further-more,removal efficiency of ammonia nitrogen was decreased to 80% and accumulation efficiency of ni-trite nitrogen was 90% when Na2 SO4 salinity was increased to 12 g/L in the activated sludge system. Accumulation of nitrite nitrogen could be accomplished and short-cut nitrification and denitrification could be achieved under certain salinity.
