Embodiment

[0016] Embodiment, please refer to the figure, the present invention provides a technical solution: a kind of soil purification equipment for arsenic pollution, including arsenic pollution treatment well 15, immobilized microbial ball 6, magnetic field generating device 9, water pump 12 and water spray pipe 13. The arsenic pollution treatment well 15 consists of a sandstone layer 1, an artificial matrix layer 2, an immobilized microorganism layer 3, and a water-permeable layer 4 from outside to inside. The artificial matrix layer 2 is composed of activated alumina and limestone, and the immobilized microorganism layer 3 puts immobilized microbial balls 6, which are made of activated sludge and metallic nickel. The activated sludge and metallic nickel are fully mixed with chemical agents according to the ratio of 5:1, and then the activated sludge and metallic nickel are fully mixed. The mixture of metal nickel is made into a spherical shape through a mold, then air-dried, and t...

Abstract

The invention discloses purification equipment for soil polluted by arsenic. The purification equipment comprises an arsenic pollution treatment well, an immobilized microorganism ball, a magnetic field generation device, water pumps and water spray pipes. A gravel layer, an artificial matrix layer, an immobilized microorganism layer and a water-pervious layer are arranged on the arsenic pollution treatment well in sequence from outside to inside. The artificial matrix layer is composed of activated aluminum oxide and limestone. The magnetic field generation device comprises a spiral coil, a transformer and a power source. The spiral coil is wound around the periphery of the immobilized microorganism layer and electrically connected with the transformer. The transformer is electrically connected with the power source. The water-pervious layer is composed of a film assembly. A water well is arranged in the middle of the water-pervious layer. Water drawing pipes are connected in the water well and connected with the water pumps. The water spray pipes are connected to the water pumps. The water spray pipes are evenly distributed on the surface of the soil. According to the purification equipment, arsenic 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 arsenic pollution. 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] At present, the immobilization technology of microorganisms has been widely concerned at home and abroad. For example, the patent No.: 200910056687.X patent specification introduces a preparation method of immobilized microorganisms. It has a fixed shape in the sewage, and the microorganisms do not lose their activity, and has a...
