Embodiment 1

[0033] In this embodiment, the cloth-like arsenic-absorbing fiber material used to make the inner core is activated carbon fiber cloth modified by magnesium ferrite nanoparticles (magnesium ferrite nanoparticles in the cloth-like arsenic-absorbing fiber material account for 15wt%), and the cloth-like arsenic The porosity of the adsorption fiber material is 65%, the average pore diameter of macropores is 5-50 μm, and the average pore diameter of micropores is 0.005-0.2 μm. Put the Ф200mm×1000mm arsenic removal inner core into the shell to make a fixed-bed arsenic processor, which is connected with the arsenic-containing water tank to be treated and the desorption regeneration system. A rapid arsenic detection reagent column and a 100ppb and 500ppb contrast column are installed side by side, wherein the arsenic rapid detection reagent column is connected to the water outlet of the fixed bed arsenic processor.

Abstract

The invention belongs to the technical field of water treatment and particularly provides an arsenic removal device with monitoring and regenerating functions and a use method thereof. The arsenic removal device consists of a main body, a regenerating device, a monitoring system and a power control system, wherein the main body is a fixed bed processor equipped with an inner core made from a cloth-shaped arsenic adsorption fiber material. The arsenic removal device is characterized in that the cloth-shaped arsenic adsorption fiber material is adopted to manufacture the arsenic removal inner core, the arsenic removal inner core is formed by rolling the cloth-shaped arsenic adsorption fiber material around a central shaft, the arsenic removal inner core is cylindrical, is tight in interlayer lamination and is vertically mounted in a housing, and no gap exists between the layers of the cloth-shaped arsenic adsorption fiber material or between the arsenic removal inner core and the inner wall of the housing; the regenerating system consists of a regenerated liquid tank, a pump valve and a pipeline; and the monitoring system consists of a quartz column with a rapid arsenic detection reagent and comparison columns. The arsenic removal device has the advantages of excellent water permeability, high arsenic removal efficiency, easy desorption regeneration and the like, can monitor the arsenic concentration of water in real time and provides instructions for desorption regeneration while ensuring that the effluent meets the discharge standard.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to an arsenic removal device with monitoring and regeneration functions and a use method thereof. Background technique [0002] Arsenic pollution in water seriously affects environmental safety and threatens people's health. The current technologies for removing arsenic from water mainly include coagulation sedimentation, adsorption, and reverse osmosis. The coagulation and sedimentation method is suitable for water bodies with high arsenic concentration, but it is difficult to meet the treatment requirements for water bodies with medium and low concentrations of arsenic, so it is usually used as a pretreatment process for arsenic-containing wastewater. The reverse osmosis method has high cost, high energy consumption, complex operation, and high requirements for influent water, and is not suitable for the treatment of industrial wastewater or large-scale natura...
