Down-flow hanging sponge (DHS) reactor was applied for efficient organic removal and ammonium oxidation of high salinity wastewater. The combined DHS process which was made by connecting three identical DHS reactors in series was fed with an artificial coke-oven wastewater containing a large amount of phenol and ammonium nitrogen with high salinity. Organics were removed mainly in the 1st reactor while almost all of ammonium nitrogen was oxidized in the following reactors. As a result of microflora analysis, bacterial clones involved in nitrification were rather detectable in the 2nd and 3rd reactors than in the 1st reactor, suggesting that different microfloras were established along the DHS.

采用下流式悬挂式海绵(DHS)反应器对高盐度废水进行高效的有机物去除和氨氧化处理。以含有大量苯酚和高盐度氨氮的焦化废水为原料，串联三个相同的DHS反应器组成的组合DHS工艺。有机物主要在第一级反应器中被去除，而氨氮在后续的反应器中几乎全部被氧化。微生物区系分析的结果是，参与硝化作用的细菌克隆在第二和第三反应器中比在第一反应器中更容易检测到，这表明在DHS沿线建立了不同的微生物区系。
