Equipment for extracting fulvic acid from water body

The invention provides equipment for extracting fulvic acid from a water body and a preparation method thereof. The equipment for extracting fulvic acid from a water body comprises a raw water supply unit, a pretreatment unit, a nanofiltration concentration unit, an acid-base value regulating unit, a water tank, a master control system, a filtration purification unit and a fulvic acid extraction unit. The fulvic acid extraction unit comprises a leaching apparatus, an alkali lye chemical tank, an adsorption enrichment apparatus and an ion exchange unit. The filtration purification unit can separate fulvic acid from insoluble impurities. The fulvic acid extraction unit can be used for adsorbing and purifying fulvic acid so as to obtain high-concentration fulvic acid extracting solution. The equipment for extracting fulvic acid from the water body has a simple structure, has high degree of automation and is convenient to operate. 本发明提供了种用于提取水体富里酸的设备及制备方法，其中，用于提取水体富里酸的设备包括原水供给单元、预处理单元、纳滤浓缩单元、酸碱度调节单元、水箱、总控制系统、过滤净化
