| 摘 要： | 开发了一种适用于微污染原水预处理及污水深度处理的新工艺———BIOSMEDI滤池 ,它以轻质滤料为过滤介质 ,采用与填料相适应的独特滤池构造 ,同时采用脉冲反冲洗、气水同向流。该滤池具有滤料比表面积大 ,不易堵塞 ,滤层阻力小 ,滤速高 ,反冲洗耗水、耗气小等优点。试验表明 ,该生物滤池在 10℃以上时氨氮的去除负荷≥ 0 .5kgNH3-N/(m3·d)。

| Abstract: | A new biological process called BIOSMEDI for pretreatment of micro-polluted source water and advanced treatment of wastewater was developed.In this process,light media were used in the filter which was of special structure.Pulse air-water backwashing was adopted in cocurrent fashion.The features of the filter included large specific surface area,free of clogging,low resistance,high filtration speed and low consumption of backwashing water and air.The experiments showed that ammonia nitrogen removal loading is higher than 0.5 kgNH3-N/(m3*d) when the temperature is over 10 ℃. |
