Embodiment 1
[0024] Inner Mongolia calcium-based bentonite is selected, the organic modifier is cetylpyridinium chloride (CPC), and the dosage is 100% CEC. The organic modification was carried out in a box ultrasonic reactor for 2 minutes, and then placed in a rectangular resonant cavity microwave reactor for conditioning for 2 minutes. The ultrasonic frequency is 20kHz, the power is 2000W, and the microwave power is 5000W. Bake at 60°C for 12 hours, and grind through a 100-mesh sieve. The obtained organic bentonite has stable properties and uniform texture, and is used for the treatment of 2-naphthol-containing wastewater. When the mass ratio of the organic bentonite to wastewater is 1:3000, the removal rate of the wastewater with an organic matter concentration of 30 mg / L reaches 95%.
Embodiment 2
[0026] Lin'an sodium-based bentonite is selected, the organic modifier is cetyltrimethylammonium chloride (CTMAC), the dosage is 25% CEC, and the mass ratio of bentonite to modifier solution is 1:0.8 to prepare a paste. First carry out organic modification in the vibrating box ultrasonic reactor for 10s, and then place it in a rectangular resonant cavity microwave reactor for conditioning for 10s. The ultrasonic frequency is 120kHz, the power is 200W, and the microwave power is 100W. Bake at 120°C for 20 minutes, and grind through a 100-mesh sieve. The obtained organobentonite is stable in properties and uniform in texture, and is used for wastewater treatment containing 2-naphthol (30mg / L) and phenanthrene (1mg / L) respectively. The removal rate of Hephenanthrene reaches 95% and 99%.
Embodiment 3
[0028]Acidified Lin'an sodium-based bentonite is selected, the organic modifier is dodecyltrimethylammonium bromide, and the dosage is 150% CEC. The mass ratio of bentonite to modifier solution is 1:4 to prepare a paste. The organic modification was carried out in the vibrating box ultrasonic reactor for 60s, and then placed in a rectangular resonant cavity microwave reactor for conditioning for 1min. The ultrasonic frequency is 40kHz, the power is 1000W, and the microwave power is 700W. Bake at 120°C for 20 minutes, and grind through a 100-mesh sieve. The obtained organobentonite has stable properties and uniform texture, and is used for decolorization treatment of wastewater containing 2-naphthol (30mg / L) and orange II (50mg / L) respectively. When the mass ratio of organobentonite and waste water is 1: 3000, the The removal rates of naphthol and phenanthrene reached 95% and 99%.
