Abstract

The present invention provides a double helix nanophase ecosphere, having continuous double-helix, the surface is formed by extending of mass bends or each S shaped part. Each part shows radial arrangement to achieve maximal surface area and provide void ratio. This new design provides countless pleats on the surface of the double-helix, so as to have fantastic specific surface and poriness; and it further has stronger impact strength and tensile yield strength. The conglobulation of the invention contains nano ceramics powder, vinyl chloride monomer and all kinds of stabilizing agent and forming agent. The double helix nanophase ecosphere is used for water treatment, air purification, auto air filter, central air condition cycle water treatment, flowers and trees industry, health products industry, industrial filtering material, chemical fillings, catalyst carrier, the invention also provides a preparing method and use of the ecosphere.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to an ecological filter material. Background technique [0002] Due to the rapid development of industrialization and urbanization, the total annual discharge of industrial wastewater and urban sewage has reached 50 billion tons, and the treatment rate is low. A large amount of wastewater is discharged into natural water bodies, which has caused about 80% of our country's rivers and lakes to be affected to varying degrees. pollution. In the "Tenth Five-Year Plan" plan, by 2005, the national sewage treatment rate is planned to reach 45%, and the sewage treatment rate in cities with more than 500,000 residents will reach more than 60%, with a daily sewage treatment rate of more than 58 million tons. [0003] The rapid development of the aquaculture industry has changed the farming method from extensive farming to intensive farming. However, while increasing production and incr...
