Sintering-free raw material ball filler for rural sewage treatment system, and preparation and maintenance method of sintering-free raw material ball filler
The invention discloses a sintering-free raw material ball filler for a rural sewage treatment system as well as a preparation method, a maintenance method and application of the sintering-free raw material ball filler. Comprising 50-60% of fly ash, 10-20% of dewatered sludge, 20-30% of cement, 5-8% of calcium oxide, 1-2% of ammonium acetate, 3-5% of sodium silicate and 0.04-0.06% of triethanolamine. Preparing a raw material ball filler by adopting a sintering-free process; the obtained raw material ball filler is sequentially subjected to normal-temperature curing, high-temperature steam curing and water spraying curing, a filler product with excellent ineffective efficiency is prepared from a finished product, the filler product is applied to a BAF system, and the removal rates of COD and NH3-N in the stable period can be stabilized at 84% and 71% respectively. In a word, the fly ash is used as a main raw material, the cement and the dewatered sludge are added, the calcium oxide is used as an auxiliary exciting agent, the ammonium acetate is used as a pore increasing agent, the specific surface area of the filler is increased, and the raw material ball filler has high porosity, large specific surface area, moderate strength and excellent performance.
本发明公开了一种农村污水处理系统免烧结生料球填料、制备、养护方法和应用；包括：粉煤灰50‑60％、脱水污泥10‑20％、水泥20‑30％、氧化钙5‑8％、乙酸铵1‑2％、硅酸钠3‑5％、三乙醇胺0.04‑0.06％；采用免烧结工艺制备生料球填料；得到的生料球填料依次经过常温养护、高温蒸汽养护、喷水养护及成品制作无效效率优异的填料产品，并将其应用于BAF系统中，在稳定期对COD和NH3‑N的去除率可分别稳定在84％和71％。总之本发明目以粉煤灰为主要原料，加入水泥和脱水污泥，并以氧化钙为辅助激发剂，乙酸铵作为增孔剂，增大填料的比表面积，且生料球填料具有较高的孔隙率，较大的比表面积和适中的强度，具有优异的性能。
