Abstract
The invention discloses a biochar defluoridation and regeneration integrated device. The biochar defluoridation and regeneration integrated device comprises a stainless steel outer tube, a stainless steel inner tube, ultrasonic resonators, polyurethane foam, a biochar layer, a filler opening, a water inlet pipe, a water outlet pipe and a waste fluid outlet pipe, and the stainless steel outer tube and the stainless steel inner tube form an inner-outer sandwich structure; the ultrasonic resonators are distributed uniformly on the outer side of the stainless steel inner tube and connected with an external PLC control panel through a closed cable coupling box, the polyurethane foam is filled in a sandwich layer between the stainless steel outer tube and the stainless steel inner tube; the biochar layer is arranged in the stainless steel inner tube, the filler opening, the water inlet pipe, the water outlet pipe and the waste fluid outlet pipe are arranged in the stainless steel inner tube and respectively provided with valves, and the water inlet pipe is located at the bottom of the stainless steel inner tube and provided with water inlet water distribution pipes and a sieve plate to distribute water uniformly. The biochar defluoridation and regeneration integrated device disclosed by the invention has the advantages of simple and convenient structure, simple operation, high defluoridation efficiency and low cost, and ultrasonic regeneration is used to reduce carbon loss, lower energy consumption and avoid no secondary pollution, so as to be beneficial to decreasing the overall structure of a defluoridation device and popularization and application of the defluoridation device.
Description
technical field [0001] The invention belongs to drinking water treatment equipment, in particular to an integrated device for defluorination and regeneration of biomass charcoal. Background technique [0002] In my country, excessive fluorine content in groundwater has been perplexing people in many economically underdeveloped areas. Most of the drinking water in my country comes from groundwater. my country is one of the main high-incidence areas of endemic fluorosis in the world. The removal of fluorine in groundwater needs to be solved urgently. Fluorine is an essential trace element in the human body, which plays an important role in the toughness of bones and teeth. The World Health Organization regards the mass concentration of fluoride in drinking water as 0.5-1.5mg / L as the optimal concentration range beneficial to the human body, and my country stipulates that the fluoride content in drinking water is 1.0mg / L. Long-term drinking of excess fluoridated water can caus...
