The invention relates to the technical field of sewage treatment and particularly discloses a composite quartz sand filter material for sewage treatment. The composite quartz sand filter material is composed of quartz sand-based foamed ceramic and nano bismuth oxide loaded on the quartz sand-based foamed ceramic, wherein the porosity of the quartz sand-based foamed ceramic is 60-75%, and the quartz sand-based foamed ceramic comprises the following components in parts by weight: 50-60 parts of quartz sand, 10-15 parts of diatomite, 5-12 parts of fly ash, 5-12 parts of kaolin, 5-8 parts of boronoxide and 5-8 parts of calcium carbonate. The invention also provides a preparation method of the composite quartz sand filter material. The composite quartz sand filter material provided by the invention has the characteristics of integrating adsorption, filtration and photocatalysis, has strong adsorbability and high pollutant removal rate, and overcomes the defects of small pollutant adsorption variety range, small adsorption force, insufficient adsorption capacity and the like of a single quartz sand filter material.
本发明涉及污水处理技术领域，具体公开了一种污水处理用复合型石英砂滤料，所述复合型石英砂滤料为石英砂基泡沫陶瓷和负载在石英砂基泡沫陶瓷的纳米氧化铋组成，所述石英砂基泡沫陶瓷的孔隙率为60~75%，所述石英砂基泡沫陶瓷包括以下重量份组分：石英砂50~60份、硅藻土10~15份、粉煤灰5~12份、高岭土5~12份、氧化硼5~8份、碳酸钙5~8份。本发明还提供了复合型石英砂滤料的制备方法。本发明的复合型石英砂滤料具有集吸附、过滤、光催化为一体的特点，具有吸附性强、对污染物去除率高，克服单一石英砂滤料吸附污染物种类范围小、吸附力小、吸附容量不足等缺陷。
