Embodiment Construction

[0030] Describe in detail below in conjunction with accompanying drawing. It should be noted that the left, right, up, down, etc. mentioned in the following descriptions are all based on the directions shown in the drawings.

[0031] see figure 1 The present invention provides a treatment device for groundwater with excess organic matter, and its main structure includes two parts: a groundwater lifting system and an advanced oxidation treatment system.

[0032] Among them, the main structure of the groundwater lifting system is the lifting well 7, and a rotatable filter screen 8 is arranged in the lifting well, and the groundwater is lifted to the original horizontal line under the suction of the lifting pump 4, and the groundwater flows through the filter screen during the lifting process. 8 is filtered so that the next step is processed; at the same time, in order to prevent the filter screen 8 from clogging, a needle cleaner is specially provided.

Abstract

The invention provides an apparatus for removing organic matters in underground water. The apparatus mainly comprises an underground water lifting system and an advanced oxidation treatment system. The invention further discloses a method for removing organic matters in underground water by using the apparatus. According to the invention, aeration in the advanced oxidation treatment system is realized, the problem of rapid dissipation of ozone during aeration is effectively overcome, organic pollutants in underground water are effectively removed in situ, the toxicity of high-concentration organic matters is rapidly abated, and the apparatus and the method are applicable to all the organic pollution areas of underground water.

Description

technical field [0001] The invention relates to a treatment device for groundwater with excess organic matter, in particular to a device for removing organic pollutants in groundwater. [0002] The invention also relates to a method for removing organic matter in groundwater by using the above-mentioned device. Background technique [0003] Groundwater is an important source of drinking water and a strategic resource. With the rapid development of economy and society, the pollution of groundwater around some cities and industrial enterprises is showing a worsening trend, which seriously threatens the safety of groundwater drinking water sources. Nowadays, groundwater is seriously polluted by organic matter. The main pollution indicators are benzene, carbon tetrachloride, trichlorethylene, etc. Conventional physical, chemical and biological methods are difficult to meet the technical and economic requirements of purification treatment. How to deal with this kind of groundwate...
