Embodiment 1

[0019] Accompanying drawing is a kind of specific embodiment of the present invention, and this embodiment comprises that the low-temperature water containing diclofenac 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 backwashes the water inlet pipe 8 and the backwash in the water distribution chamber 19. The flushing pump 9 is connected, the return pipe 21 is connected with the return pump 15, the low-temperature water in the water distribution chamber 19 flows upwards through the plastic porous plate 15 and the supporting layer 16, and the air compressor 7 inflates the aeration pipe 20 at the same time, and after aeration The head 23 and the aeration disc 24 flow upwards to provide sufficient oxygen for the aerobic microorganisms, and the low-temperature water flows into the magnetic bio-filter layer 5 on the upper part of the aeration disc through the magnetic bio-filter layer 5 at t...

Abstract

The invention belongs to the technical field of wastewater treatment and relates to a device and method for treating diclofenac wastewater in a low-temperature environment. A cathode bar (13) of the device is connected with a direct-current power supply (1) through a cathode wire (2), an anode plate (14) is connected with the upper end of a spiral coil (11) of an electromagnetic field generating device, the lower end of the spiral coil (11) of the electromagnetic field generating device is connected with the direct-current power supply (1) through an anode wire (3) and a slide resistor (22). The device is simple in structure and compact in arrangement and achieves the removal purpose through physical, chemical and biological treatment conducted on the diclofenac wastewater under the low-temperature condition.

Description

technical field [0001] The invention belongs to the technical field of wastewater treatment, in particular to a device for treating diclofenac wastewater in a low-temperature environment and a treatment method thereof. Background technique [0002] Diclofenac is a non-steroidal anti-inflammatory drug with anti-inflammatory, analgesic and antipyretic effects. For rheumatoid arthritis, adhesive spondylitis, non-inflammatory joint pain, arthritis, non-articular rheumatism, pain caused by non-articular inflammation, various neuralgia, cancer pain, post-traumatic pain and various inflammations resulting in fever etc. Studies have shown that long-term intake of trace levels of diclofenac can induce its side effects, such as hypotension, renal failure, convulsions, gastrointestinal irritation, respiratory depression, etc., which pose a potential threat to human health; at the same time, diclofenac enters the environment , will cause certain harm to aquatic organisms and ecologica...
