基于填料技术的村镇生活污水脱氮处理研究进展
|
摘要
村镇生活污水,因其水质水量波动大、C/N比偏低、缺乏专业管理等难点,如何高效脱氮是其治理的关键环节。从稳定生态环境、截留大颗粒污染物、强化菌种优势、强化传质作用、形成脱氮微系统等角度,解释了填料强化生活污水脱氮的原理;从实践角度探讨了填料对村镇生活污水脱氮的改善效果。提出在今后村镇生活污水治理中,应充分利用填料自身技术的优势,开发因地制宜并能高效脱氮的生活污水处理设备。
Due to the large fluctuation in water quality and water quality, low C/N ratio, lack of professional management, etc., the problem of rural domestic sewage treatment has become increasingly serious. Removing nitrogen effectively is the key to its governance. In this paper, the principle of nitrogen removal from domestic sewage by bio-carriers was discussed in terms of stabilizing the ecological environment, retaining large particle pollutants, strengthening the advantages of bacteria, enhancing the mass transfer, and forming denitrification micro-systems. From the perspective of practice, the effect of bio-carriers on the denitrification of rural domestic sewage was explored. It's proposed that in the future treatment of rural domestic sewage, the advantages of various bio-carriers should be fully utilized to develop domestic sewage treatment equipment that can be adapted to local conditions and can efficiently remove nitrogen.
