Embodiment 1

[0018] Accompanying drawing is a kind of specific embodiment of the present invention, and this embodiment comprises that the low-temperature water containing naproxen in the high water tank 17 enters the water distribution chamber 19 through the water inlet pipe 18 through the peristaltic pump 10, and backwashes the water inlet pipe 8 in the water distribution chamber 19 Connected with the backwash pump 9, the low-temperature water in the water distribution chamber 19 flows into the anaerobic magnetic biological filter material layer 6 through the plastic porous plate 15 and the support layer 16, and performs anaerobic reaction. At the same time, the aeration pipe 20 and the air compressor 7 Connected, the air compressor 7 inflates the aeration pipe 20, and mixes with the effluent of the anaerobic magnetic biological filter material layer 6 to flow upwards, providing sufficient oxygen for the aerobic microorganisms, and the low-temperature water containing naproxen in the elect...

Embodiment 2

[0020]The low-temperature water containing naproxen in the high-level water tank 17 enters the water distribution chamber 19 through the water inlet pipe 18 through the peristaltic pump 10, and the backwash water inlet pipe 8 in the water distribution chamber 19 is connected with the backwash pump 9, and the low-temperature water in the water distribution chamber 19 Flow into the anaerobic magnetic biological filter material layer 6 through the plastic porous plate 15 and the supporting layer 16, and carry out anaerobic reaction, and the aeration pipe 20 is connected with the air compressor 7 simultaneously, and the air compressor 7 inflates the aeration pipe 20, and The effluent from the anaerobic magnetic biological filter material layer 6 is mixed together and flows upwards to provide sufficient oxygen for the aerobic microorganisms. The low-temperature water containing naproxen is filled with the particle electrode layer 4 in the electro-biodegradation reaction tank, and the...

Abstract

The invention belongs to the technical field of waste water treatment and relates to a device and method for treating naproxen waste water under a low temperature environment. The device is composed of a water distribution chamber, an anaerobic magnetic-force intensified biological filter tank, an electric-biological degradation reaction tank and an aerobic magnetic-force intensified biological filter tank, and a negative plate (13) and a positive plate (14) of the electric-biological degradation reaction tank are in series connection between a spiral coil (11)of an aerobic magnetic biological filter material layer (5) and a spiral coil (11) of an anaerobic magnetic biological filter material layer (6), then are in series connection with a sliding resistor (21) and then are connected with a direct current power source (1). Water is treated through the water distribution chamber, the anaerobic magnetic biological filter material layer (6), a filling particle electrode layer (4) and the aerobic magnetic biological filter material layer (5) in sequence and then drained out. The device is compact in arrangement and simple in structure, and the naproxen waste water is treated physically, chemically and biologically under the low temperature condition, so that the removal purpose is achieved.

Description

technical field [0001] The invention belongs to the technical field of wastewater treatment, and in particular relates to a device and a treatment method for treating naproxen wastewater in a low-temperature environment. Background technique [0002] Naproxen (Naproxen) is a commonly used non-steroidal anti-inflammatory drug (NSAIDs), has been widely used in the world, is the world's most important antipyretic analgesics and one of the best-selling over-the-counter drugs. However, due to its direct or indirect emissions, naproxen has been detected in a variety of environmental waters. Studies have shown that long-term intake of trace levels of naproxen can induce heart disease and stroke, and may also have toxic effects on the lungs, posing a potential threat to human health; , The ecological system produces certain harm, leading to water quality safety problems. At present, research results show that naproxen has been detected in surface water, groundwater, and even drink...
