Microbial enhancement agent for removing hexavalent chromium by using mineral/biomass as carrier and preparation method of microbial enhancement agent

The invention discloses a microbial enhanced agent for removing hexavalent chromium by using minerals/biomass as a carrier and a preparation method thereof. The microbial enhanced agent is prepared from the following raw materials: clay minerals, waste biomass and microbial raw materials. According to the method, the waste biomass material and the clay mineral are combined, and the microbial strain is coated by adopting an immobilization technology, so that a long-acting nutrient source is provided for microorganisms, the biomass is increased, and the capacity of removing hexavalent chromium is improved. 本发明公开了一种以矿物/生物质为载体用于去除六价铬的微生物强化药剂及其制备方法，由以下原料制备获成：粘土矿物，废弃生物质，微生物原料。本发明将废弃生物质材料和粘土矿物相结合，采用固定化技术将微生物菌种包覆，为微生物提供长效营养源，增加生物量，提升去除六价铬能力。
