| Abstract: | Dinitrotoluene(DNT) wastewater was treated by acid precipitation and ultrasonic-high gravity-ozone oxidation process.The effects of different acids and wastewater pH on acid precipitation were studied.The experimental results show that: When the wastewater pH is adjusted to 1.0 by adding H2SO4 solution with 98% of mass fraction,the effect of acid precipitation is better with 38.50% of COD removal rate and 45.26% of nitro compound removal rate,and the precipitate is mononitrotoluene sulfonic acid;After the a... |
