Rural small well water defluorination device and application method thereof

Abstract

The invention relates to a small-scale rural well water defluorination device and an application method thereof, belonging to the technical field of water treatment. The present invention is placed at the wellhead, and the well water is connected with a small electric pump through a pipeline, and the small electric pump pumps the well water into the defluoridation pretreatment part, and the well water is filtered through a filter net after being treated by the pretreatment filter element and enters the defluorination part, and the well In the defluoridation part, the water is treated by the defluoridation filter element to remove fluoride, and then filtered through the filter screen into the water storage tank, and finally discharged from the faucet. The device of the invention is simple in structure, and the only energy consumption is a small electric pump, so that it can be applied in remote areas, easy to operate, and does not need human control. When water is needed, the electric pump can be turned on. The materials used in the invention are mainly activated alumina and bone charcoal. These two materials are low in price and have a good defluorination effect. They are also easy to obtain in remote rural areas. Even in remote areas, the materials in the device can be replaced, which expands the scope of the present invention. application range.

Description

technical field [0001] The invention relates to a small-scale rural well water defluorination device and an application method thereof, belonging to the technical field of water treatment. Background technique [0002] Fluorine is one of the essential trace elements for the human body. Ingesting a small amount of fluorine can effectively prevent dental caries. On the contrary, long-term excessive intake of fluorine will lead to "fluorosis", manifested as dental fluorosis, skeletal fluorosis and nerve damage. In some cases, excessive fluoride intake may also interfere with carbohydrate, protein, vitamin and mineral metabolism and DNA synthesis. Studies have shown that high doses and short-term exposure to fluoride can impair kidney function. Some studies have also shown that fluoride can interfere with the function of the pineal gland as well as the brain. The pineal gland is the main place for fluorine accumulation, and its internal fluoride concentration is higher than th...
