Microbial composite filler as well as preparation method and application thereof
The present invention provides a microbial composite filler, which comprises: 60-70 wt% of a mineral raw material; 5 to 10 wt% of a surfactant; 10 to 20 wt% of a hydrophilic affinity substance; and 15 to 25 wt% of a binder; wherein the mineral raw materials comprise volcanic ash and one or more raw materials selected from humus soil, peat, zeolite, alunite, kaolin and limonite; and the volcanic ash accounts for 15 wt%-25 wt% of the mineral raw materials. The composite filler provided by the invention has the characteristics of hydrophilicity, weak acidity, no toxicity, high porosity, large specific surface area and the like, and can quickly induce mass propagation of deodorization microorganisms in sewage and enhance the activity of the deodorization microorganisms, thereby degrading and removing malodorous substances such as hydrogen sulfide, ammonia gas and the like in sewage sludge.
本发明提供了一种微生物复合填料，包括：60～70wt％的矿物质原料；5～10wt％的表面活性剂；10～20wt％的亲水亲和物质；15～25wt％的粘结剂；其中，所述矿物质原料包括火山灰以及选自腐殖土、泥炭、沸石、明矾石、高岭土和褐铁矿石中的一种或多种原料；所述火山灰占所述矿物质原料的15wt％～25wt％。本发明提供的复合填料具有亲水性、弱酸性、无毒性、孔隙率高、比表面积大等特点，能够迅速诱发污水中除臭微生物大量繁殖并能增强其活性，从而对污水污泥中的硫化氢、氨气等恶臭物质进行降解去除。
