Embodiment

[0016] Embodiment, please refer to the figure, the present invention provides a kind of technical scheme: a kind of soil purification device for lead pollution, comprises lead pollution treatment well 15, immobilized microbial ball 6, magnetic field generating device 9, water pump 12 and water spray pipe 13. The lead pollution treatment well 15 is composed of sandstone layer 1, artificial matrix layer 2, immobilized microorganism layer 3, and water-permeable layer 4 from outside to inside. The artificial matrix layer 2 is composed of clinoptilolite and limestone, and the immobilized microorganism layer 3 puts immobilized microbial balls 6. The immobilized microbial balls 6 are made of activated sludge, activated carbon and metallic nickel. The activated sludge and metallic nickel are fully mixed with chemical agents according to the ratio of 4:1, and then the activated sludge The mixture of mud and metal nickel is made into a ball through a mold, then air-dried, and then the ai...

Abstract

The invention discloses a soil purification device for lead pollution. The soil purification device comprises a lead pollution treatment well, immobilized microbial balls, a magnetic field generating device, a water pump and water spraying tubes. The lead pollution treatment well is sequentially provided with a gravel layer, an artificial substrate layer, an immobilized microorganism layer and a water permeable layer from outside to inside. The artificial substrate layer is composed of clinoptilolite and limestone. The magnetic field generating device comprises a spiral coil, a transformer and a power source, wherein the spiral coil is twined on the periphery of the immobilized microorganism layer; the spiral coil is electrically connected with the transformer; and the transformer is electrically connected with the power source. The water permeable layer is composed of a film component, and a water well is arranged in the middle of the water permeable layer. A water pumping tube is connected into the water well and is connected with a water pump, and the water pump is connected with the water spraying tubes. The water spraying tubes are evenly distributed on the surface of soil. According to the soil purification device for lead pollution, lead in the soil can be removed, and water is recycled.

Description

technical field [0001] The invention relates to the field of soil improvement, in particular to a soil purification device for lead pollution. Background technique [0002] Lead is the only trace element not needed by the human body. It is a stable and non-degradable pollutant that can accumulate in the environment for a long time. According to reports, for people who have been exposed to trace amounts of lead for a long time, the accumulated lead can hinder the formation of blood cells, leading to mental decline, low academic and work performance; when the accumulation reaches a certain level, people will have chronic mental disorders, nightmares, insomnia, headaches, etc. Symptoms of poisoning; severe cases may also have fatigue, loss of appetite, nausea, abdominal distension, abdominal pain or diarrhea. Lead can also enter the brain tissue through the blood, damage the cerebellum and cerebral cortex, interfere with metabolic activities, cause insufficient supply of nutri...
