The results indicate that ① the reactor with sulfur particle size of 2.8-5.6 mm can effectively remove nitrate from nitrified leachate up to a concentration of 400 mg/L NO - 3 N at a hydraulic retention time of 5.71h;② the minimum hydraulic retention time necessary for complete denitrification depends on sulfur particle size and influent nitrate concentration;③the maximum volume...

结果表明，当HRT为5.71h，硫磺粒径为2.8－5.6mm时，最高处理浓度（以NO－3－N计）达400mg／L。达到完全反硝化所需的最小停留时间取决于硫磺粒径及进水硝酸盐浓度。硫磺粒径为2.8－5.6mm，5.6－11.2mm，11.2－16mm时，NO－3－N最高容积负荷分别为594，278，175.4g／（m3d）。NO－3－N最大表面负荷约为0.68g／（m2d），是自养反硝化的控制因素，与硫磺粒径无关。
