Water purification type pervious concrete capable of removing nitrogen and phosphorus and preparation method of water purification type pervious concrete
The invention relates to water purification type pervious concrete capable of removing nitrogen and phosphorus and a preparation method of the water purification type pervious concrete. The pervious concrete is prepared from the following components in parts by weight: 35 to 42 parts of cement, 165 parts of aggregate, 10 to 15 parts of powdered polyaluminum chloride, 2.8 to 3.5 parts of cementingagent and 15 to 17.5 parts of water. The aggregate comprises the following components in parts by weight: 40-60 parts of crushed stone, 30-40 parts of zeolite, 25-35 parts of granular activated carbonand 40-60 parts of crushed aerated bricks. Compared with the prior art, the water purification type concrete has the advantages of strong water purifying function, capability of synchronously removing nitrogen and phosphorus, simple preparation method and the like, and is suitable for being used in sponge city construction engineering.
本发明涉及一种可脱氮除磷的净水型透水混凝土及其制备方法，透水混凝土包括以下重量份的组分：水泥35～42份，骨料165份，粉剂的聚合氯化铝10～15份，胶结剂2.8～3.5份和水15～17.5份；所述的骨料包括以下重量份的组分：碎石40～60份，沸石30～40份，颗粒活性炭25～35份，破碎后的加气砖40～60份。与现有技术相比，本发明具有净水功能强、可同步去除氮和磷、制备方法简单等优点，适合在海绵城市建设工程中使用。
