Study on Manufacture and Performance of Permeable Brick by Waste Filter Material of Water Treatment Plant
With the development of urbanization,the impermeable surfaces have increased in cities day by day,which cause frequent urban waterlogging and increased pollution of rainwater runoff.Based on this,that waste filter material are mainly proposed to make permeable brick,with cement,activated carbon,fly ash and other raw materials.The production method and process are introduced.The influence of the mix ratio of raw materials on the mechanical properties and water purification performance of permeable brick are studied and discussed.The results show that the permeable brick with 77％waste filter material content and 10％activated carbon content has good performance.The compressive strength is 6.641 MPa.The removal rate of COD,TN,TP,TOC is 11.80％,23.24％,73.10％and 58.86％respectively.All the data meet the discharge standard.The permeable brick made of waste filter material in water treatment plant has not only good practical value,but also certain economic and environmental benefits.
