Abstract

The invention discloses an in-situ repair reactor for polluted underground water. The reactor comprises a first gravel layer, a reaction layer and a second gravel layer, wherein the reaction layer is arranged between the first gravel layer and the second gravel layer, the polluted underground water enters the reactor from the first gravel layer and flows out after passing through the reaction layer and the second gravel layer, an adsorbent is arranged in the reaction layer and comprises a substance A consisting of soot, coal particles or a mixture of the soot or the coal particles, a substance B consisting of nanometer silica powder, and a substance C consisting of zeolite, wherein the weight proportion of the substance A to the substance B to the substance C is 2.5:1.5:1. The in-situ repair reactor disclosed by the invention can be used for effectively removing endocrine disrupting chemicals (EDCs) in the polluted water, the adsorbent can be recycled, and the in-situ repair reactor has the characteristics of wide use range, good treatment effect, long service life, low cost, convenience for operation and maintenance, capability of being constructed and operated underground, smallinfluences to human activities, wide application prospect and the like.

Description

technical field [0001] The invention relates to the treatment of polluted water, in particular to an in-situ repair reactor for polluted ground water. Background technique [0002] In recent years, with the development of industrial and agricultural production, especially the rapid development of organic synthetic chemicals, petrochemicals, pesticides and insecticides, more and more pollutants have entered the soil and water bodies, resulting in a sharp deterioration of drinking water quality. Among them, environmental hormones (EDCs) have an increasing impact on water quality. Environmental hormones are a class of pollutants with typical hydrophobic and lipophilic properties. They are easily adsorbed on the aquifer skeleton and soil particles, and are not easy to biodegrade in the environment. They can pose a serious threat to human and animal health. It accumulates in fat through the food chain, which may cause diseases of the immune system, endocrine system, hormones, re...
