Biological ceramsite produced from water purifying agent waste residues and preparation method of biological ceramsite
The invention discloses biological ceramsite produced from water purifying agent waste residues, the biological ceramsite is prepared from a main material, an admixture and a sodium sulfate solution,the main material is prepared from the following substances in percentage by weight: 30-60% of water purifying agent waste residues, 5-20% of cement and 30-50% of fly ash; the admixture is prepared from sodium bicarbonate, sodium dodecyl benzene sulfonate and a naphthalene water reducer, wherein the weight of the sodium bicarbonate is 1 to 5 percent of the mass of the main material; wherein the weight of the sodium dodecyl benzene sulfonate is 0.2-0.5% of the mass of the main material; wherein the weight of the naphthalene water reducer is 0.2-0.5% of the weight of the main material; wherein the mass concentration of the sodium sulfate solution is 0.1-0.3%; wherein the weight of the sodium sulfate solution is 0.1-2% of the mass of the main material. The biological ceramsite is produced from the polyaluminum chloride waste residues, so that the problem of waste residue treatment of the water purifying agent is solved; the method does not generate new pollution in the production process,and is suitable for popularization and application.
本发明公开了一种利用净水剂废渣生产的生物陶粒，该生物陶粒由主料、外掺剂和硫酸钠溶液制成，所述主料由以下重量百分比的物质组成：净水剂废渣30‑60%、水泥5‑20%、粉煤灰30‑50%；所述外掺剂由碳酸氢钠、十二烷基苯磺酸钠和萘系减水剂组成，其中碳酸氢钠的重量为主料质量的1‑5%；十二烷基苯磺酸钠的重量为主料质量的0.2‑0.5%；萘系减水剂的重量为主料重量的0.2‑0.5%；所述硫酸钠溶液的质量浓度为0.1‑0.3%；所述硫酸钠溶液的重量为主料质量的0.1‑2%。本发明利用聚合氯化铝废渣生产生物陶粒，解决了净水剂废渣处理的问题；本发明方法在生产过程中不会产生新的污染，适合推广使用。
