Problems solved by technology

However, there is also the high cost of ultrafiltration membranes, resulting in high device cost and operating costs, which have certain restrictions on the application in rural areas
Recently, fluoride removal methods and devices using hydroxyapatite as the basic treatment material have appeared one after another, all of which can achieve better fluoride removal effects, but there are still certain problems in practical applications.

Abstract

The invention provides a novel integrated groundwater fluoride removal device comprising a water inlet unit (1), a defluorination reaction unit (2), an intermediate water tank (3) and a filter unit (4) which are connected with one another in sequence, wherein the defluorination reaction unit (2) is communicated with the intermediate water tank (3) through a floc preliminary interception unit (5), and a water outlet is formed in the bottom of the filter unit (4). The device is compact in structure, small in floor area, convenient in use, flexible in operation, low in treatment cost, good in fluoride removal effect, high in effluent quality and relatively good in popularization and application prospects.

Description

technical field [0001] The invention belongs to the field of water treatment, in particular to a novel integrated groundwater defluorination device. Background technique [0002] The problem of fluorine pollution in groundwater in China is serious. The distribution area of ​​high-fluorine water exceeds 1.6 million square kilometers, involving nearly 100 million people who use water. Fluorosis caused by excessive intake of fluoride through drinking water is a serious problem worldwide. [0003] Existing groundwater defluoridation technologies mainly include coagulation sedimentation, activated alumina adsorption, electrodialysis, reverse osmosis, ion exchange, adsorption, bone charcoal adsorption, and zeolite defluorination, etc. All there are certain problems in this kind of technology, so that there are certain difficulties in its popularization and application. [0004] Hydroxyapatite is a new material with good effect for defluoridation of groundwater recently, and it h...
