Abstract

The invention relates to a water permeable brick purifying rainwater. The water permeable brick is divided into an upper layer and a lower layer, wherein the upper layer is a surface layer; the lowerlayer is a base layer; and a thickness ratio of the surface layer to the base layer is 1:(5-6). The invention further relates to a method of preparing the water permeable brick purifying the rainwater. Ceramsite in the base layer of the water permeable brick can absorb suspended matter and organic matter (VOCs (volatile organic compounds)); the reduction of a water permeable rate of the water permeable brick due to gap obstruction after long-term usage is avoided; the ceramsite after zeolitization modification can absorb a small quantity of heavy metals in the rainwater; and pollution of ground water is avoided.

Description

technical field [0001] The invention relates to the field of building materials, and more specifically, to a permeable brick for purifying rainwater and a preparation method thereof. Background technique [0002] With the rapid development of my country's economy and the gradual acceleration of urbanization, the surface of the earth is gradually covered by various buildings, cement, concrete, and natural stone. This impermeable floor material does not allow rainwater to seep into the ground, causing the city's water table to drop. Moreover, in the event of heavy rain, urban waterlogging is prone to occur only by drainage system drainage. At the same time, the impermeable pavement basically cannot exchange moisture and heat with the air, and cannot adjust the surface temperature and humidity. Together with the buildings, it forms the urban "heat island effect" and increases noise, which deteriorates the urban microclimate and reduces the comfort of the city. , affecting the...
