Advanced facilities such as advanced water permeable materials and early-stage waste flow filtration devices have been introduced to reduce pollution, reduce pollution, reduce pollution, eliminate end-of-pipe and other means, and realize multi-purposes such as flood control, pollution reduction, water environment improvement, and water conservation in urban areas. Management and control, and vigorously promote the construction of "sponge city".
Advanced permeable materials at home and abroad
Permeable brick
It is made of solid industrial waste materials, household garbage, and building materials as raw materials through crushing and high-temperature firing.
Pervious asphalt
The specially-developed modified asphalt, hydrated lime, and fiber were mixed into the raw materials. It can reduce water fog and glare, reduce noise, waterproof drift, improve the visibility of road signs, and improve the slip resistance of wet roads.
Pervious concrete
The pervious concrete does not contain fine aggregates, and the thin aggregates are coated with a thin layer of cement slurry to form a honeycomb structure with even distribution of pores. Therefore, the pervious concrete has the features of air permeability, water permeability, and light weight.
Early abandoned flow filtration devic
The initial waste flow filtration device was a rainwater harvesting system process. He collected rainwater for roofing, hardened ground, etc., and used it in life.
The ground rainwater collection system adopts the method of infiltration of abandon flow or abandon flow pool. Automatic control of abandon flow is generally divided into time control and water control. The water control is divided into flow control and rainfall control.
The general requirements of the abandon flow filtration device are simple, high-efficiency, no power supply, built-in grille screen, preliminary filtration of the abandoned rainwater, automatic drainage of dirt, long service life, good safety and stability, energy saving and environmental protection.
