摘要:

人工快速渗滤系统在小城镇污水处理中具有重要的应用价值,但存在总氮去除率偏低的问题,强化硝态氮的反硝化是解决这一问题的关键。国内外针对反硝化系统及人工快速渗滤系统的研究表明,改善反硝化细菌特性、添加碳源、优化碳氮比和湿干比、增设饱水层是解决总氮去除率较低的有效方法。

关键词: 小城镇污水, 人工快速渗滤系统, 除氮, 反硝化, 碳源

Abstract:

The constructed rapid infiltration(CRI) system has great utilization value to the sewage treatment in small towns,whereas,the low total nitrogen removal rate is still a problem.The denitrification of nitrate nitrogen is a key to the problem.The researches aiming at the denitrification systems and constructed rapid infiltration systems both in China and abroad indicate that the effective methods for solving this problem of low total nitrogen removing rate are improving denitrification bacterial characteristics,increasing carbon sources,optimizing carbon/nitrogen ratio and wet/dry ratio,and setting more saturated water layers.

Key words: small town sewage, constructed rapid infiltration system, nitrogen removal, denitrification, carbon resources
