example 1
[0032] The natural rutile is ground to a particle size of 70 μm to 80 μm with a ball mill.
Embodiment 2
[0034] (1) Grinding the natural rutile with a ball mill to a particle size of 70 μm to 80 μm.
[0035] (2) The product obtained in step (1) is pulverized to a particle size of 10 μm to 20 μm with a jet mill.
Embodiment 3
[0037] Grind the natural rutile with a ball mill to a particle size of 70 μm to 80 μm, then put it into a corundum crucible, heat it to 700°C in a 20 kilowatt muffle furnace, keep it warm for 5 minutes, take it out and spread it on a stainless steel plate, and use a temperature of Air flow at 0°C for cooling and quenching.

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.
Description
technical field [0001] The invention relates to a photocatalyst prepared from natural rutile and its application in degrading wastewater containing halogenated organic substances. Background technique [0002] my country is a country that is very scarce in water resources. The per capita water resources are only a few hundred cubic meters, which is about a quarter of the world's per capita water volume. Due to the rapid development of our country's economy and the continuous improvement of people's living standards, a large amount of industrial, agricultural and domestic wastewater harmful to the environment will be produced. The annual economic loss caused by water pollution to my country is about 40-70 billion yuan. It can be seen that the shortage of water resources and serious water pollution have become important factors restricting the sustainable development of my country's economy and society. Therefore, to solve the water resource crisis, it is imperative to develo...
