Wetland composite filler applied to treatment of rural domestic sewage, and preparation method thereof
The invention discloses a wetland composite filler applied to treatment of rural domestic sewage, and a preparation method thereof. The raw materials comprise fly ash, quicklime, cement, yellow sand and scrap iron, and the finished product wetland composite filler is prepared by crushing, pulping, injection molding and blank forming, gas forming and initial setting, cutting and curing. According to the invention, the fly ash, quicklime, cement, yellow sand and scrap iron are used as raw materials to prepare the wetland composite filler according to specified weight components and corresponding preparation processes. The prepared wetland composite filler contains a large number of uniform and fine air holes, the specific surface area of the wetland composite filler is greatly increased, the wetland composite filler can make full contact with sewage, microorganism growth is facilitated, pollutants can be fully adsorbed, filtered and intercepted, and the treatment effect is better; and the wetland composite filler prepared by the invention is uniform in overall specification, all the wetland composite fillers can achieve a treatment effect, and the utilization rate of the wetland composite filler is higher.
本发明公开了应用于处理农村生活污水的湿地复合填料及其制备方法，其原料包括粉煤灰、生石灰、水泥、黄沙和铁屑，通过破碎、制浆、注模成胚、发气初凝、切割和养护制备得到成品湿地复合填料。本发明按规定的重量组分及相对应的制备流程利用粉煤灰、生石灰、水泥、黄沙和铁屑作为原料制备出湿地复合填料。本发明制备的湿地复合填料含有大量均匀而细小的气孔，大大增加了湿地复合填料的比表面积，使得湿地复合填料与污水能够充分接触，利于微生物生长，从而能够充分吸附、过滤与截留污染物，其处理效果更好；本发明制备的湿地复合填料整体规格均匀，所有湿地复合填料都能起到处理效果，其利用率更高。
