Unfired bioactive filler with ammonia removal and denitrification functions and preparation method thereof
The invention discloses an unfired bioactive filler with ammonia removal and denitrification functions and a preparation method. The active filler takes washed kaolin, attapulgite and a composite denitrification liquid inoculant as main raw materials, activated carbon as an auxiliary component, cement as an inorganic binder, polyvinyl alcohol and sodium alginate as additives and glycerol as a composite bacteria protective agent. The preparation method comprises the following steps: preparation of the composite denitrification liquid inoculant, material weighing, dry mixing, wet mixing, granulation and maintenance aging. The unfired bioactive filler provided by the invention is convenient in material taking and simple in preparation process, and during ammonia removal and denitrification ofwastewater, a strain embedded in the filler is convenient to activate, the process starting time is short, and the filler has excellent denitrification performance.
本发明公开了一种具有除氨脱氮功能的免烧型生物活性填料及制备方法，该活性填料以水洗高岭土、凹凸棒土、复合脱氮液体菌剂为主要原料，活性炭为辅助成分，水泥为无机粘结剂，聚乙烯醇和海藻酸钠为添加剂、甘油为复合菌保护剂；其制备步骤包括复合脱氮液体菌剂的制备、物料称量、干拌、湿拌、造粒和养护陈化。本发明提供的免烧型生物活性填料，其取材方便、制备工艺简单，在废水除氨脱氮时，包埋于填料内的菌种激活方式便捷，工艺启动时间短，具有优异的脱氮性能。
