AI Technical Summary

Technical Problem

In existing groundwater circulation well technology, the bubbles generated by the aeration pump are large in diameter and rise rapidly, resulting in insufficient contact time between the bubbles and the water. Multiple cycles are required to achieve the desired treatment effect, which is inefficient.

Method used

An ultrasonic generator is used to break up bubbles, which, combined with a sound grating and a start/stop controller, form an ordered bubble layer. A stable flow field is constructed through a water distribution plate, and gas-liquid separation is achieved in conjunction with a dehumidification component, thereby extending the bubble residence time and improving contact efficiency.

Benefits of technology

It significantly improves the removal rate of volatile pollutants. By using ultrasonic breaking of bubbles, acoustic grating capture, and water distribution plate rectification, it ensures that the bubble layer is evenly distributed and rises stably in the water, enhancing the gas-liquid mass transfer effect and improving the treatment efficiency.

Abstract

The invention discloses an underground water integrated treatment system with a circulating well and ground treatment equipment, and relates to the technical field of underground water integrated treatment. The waste gas treatment unit is communicated with the gas output end of the circulating well through a pipeline, the circulating well comprises an outer ring and an inner ring which are concentrically arranged in the outer ring, the gas output end is arranged at the upper end of the inner ring, and the ultrasonic generator is arranged in the inner ring. According to the invention, through the acoustic cavitation effect generated by the ultrasonic generator, large bubbles are broken into micron-scale and even nano-scale bubbles, and according to the Stokes law, the rising speed is greatly reduced and the retention time is prolonged by reducing the radius of the bubbles, so that a full contact window is provided for diffusion of volatile pollutants from water to the bubbles, and the removal rate of VOCs is greatly improved.
