Problems solved by technology

The common wet synthesis technology requires a constant temperature water bath and stirring for more than 2 hours, which consumes time, energy and water resources, and produces wastewater containing a large amount of surfactants, which needs further treatment. In addition, the synthesis process of organic bentonite is not stable. Affected the quality of modified bentonite
In addition, during the adsorption process, due to the enhanced hydrophobicity of the bentonite surface after modification, it is difficult to disperse in water and the utilization rate is low, and the solid-liquid separation is difficult after treatment, which affects the turbidity of the effluent, which is not conducive to the recycling of bentonite sludge. Limiting the application of organic bentonite in wastewater treatment and remediation of polluted environment

Abstract

The invention discloses a method for treating organic waste water with bentonite and ultrasonic waves. Granular or pulverized 10-100 mesh bentonite is added to the organic waste water, and the mass ratio of bentonite to waste water to be treated is 1:50-1:10000; Apply ultrasonic waves with a frequency of 20kHz-120kHz and a power of 100W-1200W for 10s-10min; the reaction product stays in the sedimentation tank for 10-60min, the soil-water settles and separates, and the waste water is discharged after reaching the standard. The waste water purification treatment time is greatly shortened, and the pollutant removal efficiency Improvement, simple operation, small equipment and low cost.

Description

technical field [0001] The invention relates to a method for treating organic waste water with bentonite and ultrasonic waves, in particular to a method for treating waste water containing cationic surfactants and other organic matters. Background technique [0002] Ultrasonic radiation of organic pollutants in water bodies, especially refractory organic pollutants is a new water treatment technology developed in recent years. The organic pollutants in the water body irradiated by ultrasonic waves with a frequency of 15-1000kHz are physical and chemical processes caused by cavitation effects. , growth, shrinkage and collapse and a series of dynamic processes, this process can highly concentrate the energy of the sound field in the tiny cavitation bubble, and generate discharge, light, high temperature, high pressure, and high energy at the moment when the cavitation bubble closes rapidly Density, shock wave, micro-jet and micro-fusion and other physical and chemical effects...
