MST一体化装置处理小城镇生活污水技术讨论

Study on Small-town Domestic Sewage Treatment by MST Integrated Reactor Technology

将一个或多个装满填料的模块淹没在曝气池内组成一个完整的污水处理系统,实现了不同的物理、生化处理过程在同一个反应器内完成。采用该新型一体化技术来处理小城镇生活污水,通过实验确定了其最佳运行参数,分析了工艺原理。该新型污水处理技术占地面积小、投资省、耗能低、运行管理方便,特别符合小城镇生活污水对处理工艺的要求。结果表明,对COD和氨氮的平均去除率分别达到了80.56%和72.3%,对SS的去除率可达到95%以上并且非常稳定,可用作城市杂用水。讨论了该新型污水处理技术的特,并且提出了改进建议。

The integrated reactor is a device that can realize different physical, chemical and biological treatment processes completed in one reactor. This new integration technology is used to treat small-town domestic sewage, the appropriate operating parameters are determined through experiments, and the process principles are analysed. This new sewage treatment device is small footprint, low investment, low energy consumption and easy to operate and manage, and these features make the integration technology perfectly for small-town sewage treatment. The results show that 80.56 % of COD and 72.3 % of NH3-N can be removed, and the removal of SS is outstanding and stable which can achieve more than 95 %.The effluent can be used as municipal miscellaneous water. The features of this new sewage treatment technology are discussed, and the recommendations for improvement are proposed.
