Example Embodiment

[0012] Embodiment 1: The arsenic removal system for drinking water integrated with oxidation, adsorption and filtration in this embodiment includes an arsenic removal device, a membrane module 2, a high-level water tank 1, a lift pump 9, a suction pump 11, a sludge pump 10 and an air compressor 8. The arsenic removal device is composed of an inner cylinder 3 and an outer cylinder 4, the inner cylinder 3 is sleeved in the middle of the outer cylinder 4, the bottom of the inner cylinder 3 is provided with a porous support layer 5, and the porous support layer 5 in the inner cylinder 3 The top is filled with adsorbent, a three-phase separator 7 is installed on the top of the inner cylinder 3, a water inlet is opened at the bottom of the inner cylinder, and the water outlet of the lift pump 9 is communicated with the high-level water tank 1 through the water pipe 1-1. The water outlet is connected with the water inlet located at the bottom of the inner cylinder 3 through the water ...

Example Embodiment

[0023] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the adsorbent filled above the porous support layer 5 in the inner cylinder 3 is a Mg / Al hydrotalcite adsorbent.

[0024] The Mg / Al hydrotalcite adsorbent in this embodiment is in a fluidized state in the inner cylinder, and the selected Mg / Al hydrotalcite belongs to double-layer metal oxides (LDHs), which have a wide range of sources, low prices, and are resistant to oxygen-containing metals. Anions have good adsorption properties.

Example Embodiment

[0025] Embodiment 3: The difference between this embodiment and Embodiment 1 is that the particle size of the Mg / Al hydrotalcite adsorbent is 20-450 μm.

Abstract

The invention relates to an oxidation/absorption/filtration integral drinking water arsenic removal system. The drinking water arsenic removal system solves the problem of poor arsenic removal effect of the existing drinking water arsenic removal device. The arsenic removal device in the drinking water arsenic removal system consists of an inner cylinder and an outer cylinder, wherein the inside of the outer cylinder is sleeved by the inner cylinder; a porous support layer is arranged at the bottom of the inner cylinder; a three-phase separator is arranged on the top of the inner cylinder; a water inlet is formed in the bottom of the inner cylinder; the water outlet of a high-level tank is connected with the water inlet at the bottom of the inner cylinder through a water inlet pipe; an air compressor is connected with an aerator head through an air inlet pipe; the aerator head is arranged below the porous support layer; a membrane assembly is arranged on the upper part of the area between the inner cylinder and the outer cylinder and connected with a suction pump through a water outlet pipe; a sludge discharge port is formed in the bottom of the outer cylinder and connected with a sludge pump through a sludge discharge pipe. The total content of arsenic in water treated by the drinking water arsenic removal system reaches 0.006mg/L and the water quality safety of drinking water is ensured.

Description

technical field [0001] The invention relates to a device for removing arsenic from drinking water, in particular to an integrated device for removing arsenic from drinking water which combines oxidation, adsorption and filtration. Background technique [0002] Arsenic and arsenic compounds are recognized by many authoritative organizations such as the International Institute of Cancer (IARC) under the World Health Organization (WHO), the National Institute of Environmental Health Sciences (NlEHS), and the U.S. Environmental Protection Agency (US-EPA). carcinogen. Due to human activities such as water intake for irrigation, mining, especially digging wells for drinking water, as well as the influence of the ecological environment and climate in various regions, arsenic compounds in the earth's surface are dissolved into surface water in the form of arsenate and arsenite in large quantities. There is a serious problem of arsenic pollution. Arsenic can not only cause acute an...
