The invention relates to the technical field of preparation of bone meal from phosphorus-containing sludge, in particular to bone meal prepared from phosphorus-containing sludge and a preparation method of the bone meal. The bone meal prepared from the phosphorus-containing sludge is prepared from the following raw materials in percentage by mass: 85%-95% of phosphorus-containing sludge and 5%-15% of cooked talc. The phosphorus-containing sludge is high-concentration phosphorus-containing wastewater generated in the production process of a food enterprise, and is treated by a hydrolytic acidification and anaerobic-anoxic-aerobic combined process. According to the method, the treated phosphorus-containing sludge is utilized, the cooked talc has the characteristics of strengthening, toughening, improving whiteness and reducing sintering temperature, the bone meal prepared from the phosphorus-containing sludge is reasonable in calcium-phosphorus ratio, few in impurity and high in whiteness, and the novel bone china produced from the bone meal prepared from the phosphorus-containing sludge is high in product mechanical strength and whiteness, transparent in china body, good in toughness and good in stability. And the glaze surface is smooth and has good thermal stability.
本发明涉及含磷污泥制备骨粉技术领域，具体为含磷污泥制备的骨粉及其制备方法。所述的含磷污泥制备的骨粉，由以下质量百分比的原料制成：含磷污泥85％‑‑95％、熟滑石5％‑‑15％。所述的含磷污泥，是食品企业在生产过程中产生的高浓度含磷废水，经水解酸化、厌氧‑缺氧‑好氧组合工艺处理。本发明利用一种经过处理后的含磷污泥，利用熟滑石具有增强、增韧、提高白度、降低烧结温度其特性，制得含磷污泥制备的骨粉，其钙磷比合理，杂质少，白度高，使用含磷污泥制备的骨粉生产的新型骨质瓷，产品机械强度高，白度高，瓷胎透明，釉面光润，热稳定性好。
