The invention relates to a composite biomass filter material and a preparation method thereof. The filter material is obtained through the steps that 70-90 parts by weight of plant waste and 10-30 parts by weight of waste organic plastic are subjected to steam explosion treatment and then mixed with kieselguhr according to the weight ratio of 5:1 to 4:1. The filter material is low in cost, not only can effectively filter out heavy metals in water, but also has the excellent adsorption property and can be recycled and simply treated to serve as boiler fuel, and therefore the economic practicality of the product is improved. 本发明是有关于种复合生物质过滤材料及其制备方法，为：将70-90重量份的植物废料和10-30重量份的废弃有机塑料进行蒸汽爆破处理，经蒸汽爆破处理后与硅藻土按5:1-4:1(重量比)混合得到滤材。本发明的过滤材料成本低廉，不但可以有效的过滤水中的重金属，又具有优异的吸附性能，同时还可回收经简单处理后用作锅炉燃料，增加了产品的经济实用性。
