Abstract

The invention discloses equipment for purifying arsenic-contaminated soil. The equipment comprises a water collecting pond, water collecting gutters, an arsenic contamination treatment well, immobilized microorganism balls, a magnetic field generation device, a water pump and water spray pipes. The water collecting pond communicates with the multiple water collecting gutters. The arsenic contamination treatment well is sequentially provided with a gravel layer, an artificial matrix layer and an immobilized microorganism layer from bottom to top. The artificial matrix layer is composed of activated aluminum oxide and activated carbon. The immobilized microorganism balls are put in the immobilized microorganism layer. The immobilized microorganism balls are prepared from activated sludge, activated carbon and metallic nickel. A water outlet pipe is connected into the water collecting pond and connected with the gravel layer of the arsenic contamination treatment well. A filter screen is arranged between the artificial matrix layer and the immobilized microorganism layer. A pure water pipe is arranged in the immobilized microorganism layer and connected with the water pump. The water pump is connected with the water spray pipes, and the water spray pipes are evenly distributed on the surface of the soil. The equipment can remove arsenic in the soil and achieves water recycling.

Description

technical field [0001] The invention relates to the field of soil improvement, in particular to equipment for purifying arsenic-polluted soil. Background technique [0002] Arsenic and its compounds are highly toxic, and long-term excessive intake will cause serious damage to human health, leading to chronic and acute poisoning and even cancer. In recent years, incidents of arsenic pollution in the water environment have occurred frequently, and there are also problems of excessive arsenic in drinking water in some areas. Arsenic pollution in soil usually enters the human body through food and groundwater, so soil treatment is imminent. [0003] The waste gas discharged from some factories contains a large amount of arsenic, and the waste gas falls to the ground when it encounters rainwater, causing serious arsenic pollution in the soil. In addition, the technology of immobilizing microorganisms has attracted widespread attention at home and abroad, such as the patent numbe...
