摘 要: | 以渗沥液处理站硝化池中失活的混合液为研究对象,寻求恢复硝化活性的方法,并探讨硝化反硝化反应的特性及污染物浓度对其影响。同时结合昆山鹿城垃圾发电有限公司垃圾渗沥液处理站实际运行数据,对运行参数进行了优化。研究表明:低有机物负荷的环境有利于恢复系统硝化活性;基质氨氮浓度过高或过低都不利于硝化活性的恢复;充足的碳源有助于提高反硝化速率,应合理控制回流比;通过适当减少排泥来提高污泥浓度,进而降低污泥负荷,可以有效抵抗负荷冲击。

Abstract: | Inactivated miscible liquids in Nitration pool of leachate treatment plant are chosen as the study object so as to seek the methods of recovering nitrification activity. The characters of nitrification and denitrification and the influence of contaminants concentration are discussed. Operating parameters are optimized according to the real operating data of leaehate treatment in Kunshan Lucheng Garbage Power Company Limited. The results show that lower organic load is propitious to the recovery of nitrification activity; however, too high or too low matrix ammonia concentration is detrimental to the nitrification activity recovery. Enough carbon could enhance denitrification, so the reflux ratio should be controlled reasonably. Reducing sludge loading by reducing spoil disposal could increase the resistance to load impact. |
