specific Embodiment approach 1

[0019] Embodiment 1: A water treatment system in this embodiment includes a cylindrical sleeve reactor 1, a peristaltic pump 2 and a water storage tank 3; wherein the cylindrical sleeve reactor 1 consists of an outer cylinder 1-1, a water-proof inner cylinder 1-2. Composed of cylindrical stainless steel cathode 1-3 and rod-type DSA anode 1-4; the water-proof inner cylinder 1-2 is set in the outer cylinder 1-1, and the rod-type DSA anode 1-4 is located in the water-proof inner cylinder 1-4 In 2, the inside of the water-proof inner cylinder 1-2 is the anode area, and the cylindrical stainless steel cathode 1-3 is arranged between the outer cylinder 1-1 and the water-proof inner cylinder 1-3, and the outer cylinder 1-1 and the water-proof inner cylinder The area between 1-2 is the cathode area, and the water inlet 1-5 is set at the bottom of the cathode area, and the water outlet 1-6 is set at the bottom of the anode area; The water inlets 1-5 are connected, and the water outlets...

specific Embodiment approach 2

[0028] Embodiment 2: This embodiment differs from Embodiment 1 in that the height of the water-separating inner cylinder 1-2 is 1 / 2 to 2 / 3 of that of the rod-type DSA anode 4; the others are the same as Embodiment 1.

[0029] This embodiment can ensure that the sewage maintains a good push-flow state in the reactor, and the separator can also ensure the continuity of the water flow while separating the cathode and the anode.

specific Embodiment approach 3

[0030] Embodiment 3: This embodiment differs from Embodiment 1 or Embodiment 2 in that the volume ratio of the cathode region to the anode region is (1.4-2.5): 1; other aspects are the same as Embodiment 1 or Embodiment 2.

[0031] The design of this embodiment can ensure the complete reduction of nitrate nitrogen in the cathode region under the premise that the cathode and anode provide the same amount of electrons.

Abstract

The invention discloses a water treatment system and a method for synchronously removing ammonia nitrogen and nitrate nitrogen in water by using the water treatment system, particularly relates to a water treatment device and a water treatment method for synchronously removing the ammonia nitrogen and the nitrate nitrogen in the water, and aims to solve the technical problems of low pollutant degradation rate and secondary pollution of a conventional sewage treatment electrochemical reactor. The water treatment system comprises a cylindrical sleeve type reactor, a peristaltic pump and a water storage tank, wherein the water outlet of the water storage tank is connected with the water inlet of the cylindrical sleeve type reactor through the peristaltic pump; the water outlet of the cylindrical sleeve type reactor is connected with a backflow inlet; the cylindrical sleeve type reactor consists of an outer barrel, an inner waterproof barrel, a cylindrical stainless steel cathode and a rod type DSA (dimension stable anode); the interior of the inner waterproof barrel is an anode area; a part between the outer barrel and the inner waterproof barrel is a cathode area. The method comprises the following steps: feeding sewage to be treated into the cylindrical sleeve type reactor, enabling the sewage to be treated to sequentially flow through the cathode area and the anode area, and performing electrolytic reaction on electrodes. The water treatment system and the method can be used for synchronously removing the ammonia nitrogen and nitrate nitrogen in the water.

Description

technical field [0001] The invention belongs to the field of water treatment; in particular, it relates to a water treatment device and method for synchronously removing ammonia nitrogen and nitrate nitrogen in water by an electrochemical method. Background technique [0002] The discharge of nitrogen-containing compounds can not only lead to eutrophication of the receiving water body, make the water body foul, but also cause a certain burden on the treatment of water supply. Among them, ammonia nitrogen is the main pollutant in industrial wastewater, domestic sewage and agricultural wastewater. Mainly in NH 3 (aq) and NH 4 + form exists. Ammonia nitrogen in wastewater may cause algae to grow wildly, which will lead to eutrophication of lakes, seas and other water bodies, which will cause a series of environmental problems, such as the death of aquatic organisms, and then destroy the ecosystem; when the temperature and pressure change, NH 3 (aq) can volatilize into the ...
