Abstract

The invention discloses a solar auxiliary heating air-stripping tower for repairing VOC-polluted underground water. The solar auxiliary heating air-stripping tower comprises: an air stripping tower, wherein a heating chamber, an aeration tank and a temporary storage tank which are sequentially communicated with each other are arranged in the air stripping tower; a water inlet pipeline, which is wound on the outer wall of the air stripping tower, wherein one end of the water inlet pipeline is communicated with underground sewage, and the other end of the water inlet pipeline is communicated with the heating chamber; a solar heat absorption plate, which is fixed on the outer wall of the air stripping tower, wherein the back surface of the solar heat absorption clings to the water inlet pipeline; a water pump, which is arranged on the water inlet pipeline; and a water outlet pipeline, which is communicated with the temporary storage pool, wherein the solar heat absorption plate heats sewage in the water inlet pipeline for the first time, and the heating chamber heats the sewage for the second time. According to the invention, since the water inlet pipeline is wound on the outer wall of the air stripping tower, and the back surface of the solar heat absorption plate clings to the water inlet pipeline, sufficient primary heating of sewage is effectively realized; and the sewage having undergone primary heating is subjected to secondary heating through the heating chamber, so the problem of insufficient heating efficiency is effectively solved, and the effect of increasing the removal rate of VOCs is achieved.

Description

technical field [0001] The invention relates to a solar auxiliary heat stripping tower used for remediating VOCs polluted groundwater. Background technique [0002] In recent years, people have paid more and more attention to site pollution, and soil and groundwater remediation technologies and equipment have emerged as the times require. The disposal method of volatile organic compounds in groundwater generally takes advantage of its low boiling point and volatile characteristics, and removes them by promoting volatilization. Chinese patent document CN 204737749 U discloses a groundwater in-situ remediation device, wherein the vacuum extraction and gas-liquid separation system includes a two-phase extraction well, an extraction dropper, a centrifugal gas-water separator and a claw vacuum pump, etc. The equipment adopts normal temperature gas-water separation, and the scope of applicable pollutants and extraction efficiency have certain limitations when it is actually popul...
