Water purification type water permeable brick and preparation method thereof
The invention relates to a water purification type water permeable brick and a preparation method thereof. The water permeable brick is prepared from the following components in parts by weight: 35 to45 parts of fly ash, 95 to 125 parts of large-particle aggregate, 10 to 15 parts of gypsum, 15 to 20 parts of powder polyaluminum chloride, 35 to 46 parts of cement, 0.3 to 0.5 part of aluminum powder, 0.1 to 0.3 part of steel fiber, 5 to 10 parts of nano titanium dioxide coating and 15 to 30 parts of water. The large-particle aggregate comprises the following components in parts by weight: 40-55parts of coarse sand, 25-35 parts of zeolite and 25-35 parts of granular activated carbon. Compared with the prior art, pollutants in water can be efficiently removed, nitrogen and phosphorus can besynchronously removed, and the preparation method is simple and suitable for being used in sponge city construction engineering.
本发明涉及一种净水型透水砖及其制备方法，透水砖包括以下重量份组分：粉煤灰35～45份，大颗粒骨料95～125份，石膏10～15份，粉剂聚合氯化铝15～20份，水泥35～46份，铝粉0.3～0.5份，钢纤维0.1～0.3份，纳米二氧化钛涂料5～10份，水15～30份；所述的大颗粒骨料包括以下重量份组分：粗砂40～55份，沸石25～35份，颗粒活性炭25～35份。与现有技术相比，本发明能高效去除水中污染物，可同步脱氮除磷，制备方法简单，适合在海绵城市建设工程中使用。
