Problems solved by technology

However, due to the complexity of pollutants in rainwater runoff, the purification effect of pervious concrete has certain limitations. Therefore, on the premise of ensuring the mechanical properties of pervious concrete itself, further research is needed to further improve its removal performance of pollutants.

Abstract

The invention relates to a permeable concrete pavement capable of purifying rainwater, a processing device and a preparation method. The pervious concrete pavement capable of purifying the rainwater comprises a pervious concrete lower surface layer, a pervious concrete upper surface layer located on the upper portion of the pervious concrete lower surface layer and a photocatalysis overlay layer arranged on the upper surface layer of the pervious concrete upper surface layer, the photocatalytic finishing coat is prepared from the following raw material components in parts by weight: 9 to 12 parts of floor paint, 0.5 to 1.5 parts of a curing agent, 8 to 10 parts of a diluent and 0.5 to 1.5 parts of anatase nano TiO2. The permeable concrete pavement capable of purifying rainwater has the advantages that the rainwater runoff purification capability of the pavement is improved; insoluble suspended particles, organic matters, dissolved nutrient substances and heavy metal ions in rainwater runoff can be purified, efficient resource utilization of the construction waste is achieved, environmental pollution can be reduced, and the construction waste can be used as an acquisition way of concrete raw materials and has great social and economic significance.

Description

technical field [0001] The invention relates to the related technical field of functional cement-based materials, in particular to a permeable concrete pavement capable of purifying rainwater, a processing device and a preparation method. Background technique [0002] With the leap-forward development of social economy, the process of urbanization is getting faster and faster, and the degree of industrialization is constantly improving. The contradiction between social economic development and water resources and water environment carrying capacity is prominent, and problems such as water pollution and water resource shortage are emerging one after another. With the rapid development of urbanization, the amount of rainwater runoff increases rapidly, and air pollutants and surface pollutants are washed by precipitation, which intensifies the degree of pollution. Urban rainfall runoff pollution has become the second largest non-point source pollution after agricultural non-poi...
