摘要
采用序批式进水对亚硝化菌进行定向富集培养驯化,获得了高浓度亚硝化菌,其氨氮容积去除负荷达0.5 kg/(m3.d)以上。结合悬浮生物滤池工艺,强化生物硝化处理化工类氨氮废水具有适应性强、成本低、硝化效率高的特点。在对苯胺类、抗生素类废水生化出水的强化生物硝化处理试验中,苯胺类废水氨氮去除率达80%,抗生素类废水氨氮去除率达到85%以上,氨氮去除效果较理想。试验证明该工艺比较适用于复杂的化工类氨氮废水的去除。
Highly concentrated nitrite bacteria have been enriched directionally through sequencing batch cultivation.The volumetric removal loading of ammonia-nitrogen is higher than 0.5 kg/（m3·d）.Combined with suspended biofilter process,the enhanced bio-nitrification used for treating chemical industrial type ammonia-nitrogen wastewater has better adjustability and lower cost and higher nitration efficiency.When it is used for treating aniline wastewater and antibiotic wastewater effluent biochemically,their ammonia-nitrogen removal rates reach 80% and 85%,respectively,indicating its ammonia-nitrogen removing efficiency is favorable.The test above demonstrates that this method is suitable for removing complex chemical industrial type ammonia-nitrogen wastewater.
