Application of pyrohydrolysis sludge as raw material for preparing flowerpot, water-permeable unfired sludge nutritional flowerpot and preparation method of nutrient flowerpot

The invention belongs to the technical utilization field of functional unfired flowerpots, and particularly relates to an application of pyrohydrolysis sludge as a raw material for preparing flowerpots, a water-permeable unfired sludge nutritional flowerpot and a preparation method of the nutrient flowerpot. The water-permeable unfired sludge nutritional flowerpot is prepared from the following components in percentage by weight: 20 to 50 percent of pyrohydrolysis sludge, 37 to 48 percent of cement, 10 to 30 percent of sand grains, 0.6 to 1.25 percent of saw dust and 1 to 2 percent of polypropylene fiber. The invention comprehensively solves the problems of no burning of the flowerpot, fuel saving, waste turning into wealth, nutrition supply, production cost reduction and the like. 本发明属于功能性免烧花盆技术利用领域，具体涉及热水解污泥作为制备花盆原料的应用和透水免烧污泥制营养花盆及其制备方法。透水免烧污泥制营养花盆的组成包括：热水解污泥20wt％-50wt％，水泥37wt％-48wt％，沙粒10wt％-30wt％，锯末0.6wt％-1.25wt％，聚丙烯纤维1wt％-2wt％。本发明综合解决了花盆免烧、节约燃料、变废为宝、提供营养、降低生产成本等问题。
