Low-carbon preparation method of normal-temperature unfired low-density phosphorus removal filler
The invention discloses a low-carbon preparation method of a normal-temperature unfired low-density phosphorus removal filler, which comprises the following components by weight: 5000g of fly ash, 1000g of cement, 1800g of quicklime, 250g of gypsum, 280g of polyferric sulfate and 50g of polyacrylic resin particles, the raw materials except the polyacrylic resin particles are dried and uniformly stirred according to the weight ratio, water is added, the mixture is stirred into slurry, and the slurry is prepared into the normal-temperature unfired low-density phosphorus removal filler. And adding polyacrylic resin particles, uniformly stirring to prepare spherical particles, and curing at normal temperature. The low-density phosphorus removal filler is high in particle porosity, large in microorganism loading capacity, simple to prepare, low in cost, free of burning and mainly used for removing phosphorus, meets the requirements of'carbon peak reaching 'and'carbon neutralization', has the advantage of being prepared at normal temperature, overcomes the defects that the surface of ceramsite filler is glazed and the open porosity is low, and has a good application prospect. The high-temperature preparation process and equipment of the ceramsite are not needed, so that the energy is saved, and the production cost of the biological low-density phosphorus removal filler is greatly reduced.
本发明公开了常温免烧低密度除磷填料的低碳制备方法，包括如下重量组分：粉煤灰5000g、水泥1000g、生石灰1800g、石膏250g、聚合硫酸铁280g、聚丙烯酸树脂微粒50g，将上述组分按照重量比除聚丙烯酸树脂微粒的原料进行干料搅拌均匀，加水搅拌成浆，再加入聚丙烯酸树脂微粒搅匀，制成球状颗粒，在常温条件下养护得到。本发明采用低密度除磷填料，是一种颗粒孔隙率高、微生物负载量大、制备简单、成本低、免烧的除磷为主的生物填料，符合“碳达峰”和“碳中和”，该填料具有常温制备的优点，克服了陶粒填料表面结釉、开放孔隙率低的缺点，也不需要陶粒的高温制备过程和设备，节约能源，大大降低了生物低密度除磷填料的生产成本。
