Photocatalyst and its use for treating waste water of degrading halogen organics

The invention refers to light catalyst made up from natural rutile and the application in decomposing waster water which comprises halogenated organic compound. The rutile is crushed to that the radius is 70í½80ºÞm, 10í½20ºÞm. The application steps are: blends the water and the catalyst with proport...

More Information
Summary:The invention refers to light catalyst made up from natural rutile and the application in decomposing waster water which comprises halogenated organic compound. The rutile is crushed to that the radius is 70í½80ºÞm, 10í½20ºÞm. The application steps are: blends the water and the catalyst with proportion of 1000:1; blows air into the waster water pool to make the water blend with the catalyst evenly; carries on decomposition reaction by radiating the waste water with mercury lamp whose wavelength is less than 380 nano; it stops when the thickness of the water reach to the standard, the upper clean water is discharged, and supplies the catalyst, and continue to decompose the new waste water.
