Problems solved by technology

Although the purification efficiency is high, there are disadvantages such as difficult control of reaction conditions, long treatment cycle, and high structural requirements; at the same time, the biodegradation method is only suitable for the treatment of low-toxic antibiotic sewage, and it needs to be coupled with other methods during the treatment process

Embodiment 1

[0038] 1) Weigh 5 mL of black material pure diphenylmethane diisocyanate (pure MDI), 10 mL of white material (polyurethane combined polyether: 200 kg 99.5% polyether polyol, 200 kg 99% silicone oil, catalyst and 200 kg chain extender); Mix the black material and the white material within 30s, stir with a glass rod at a speed of 100rpm until the liquid turns white, start to foam automatically for 5 minutes, until the foaming temperature drops to room temperature, the foaming is completed, divide into 2cm× 2cm×2cm square blocks, ultrasonically cleaned with 75% ethanol for 15 minutes, and dried in a constant temperature oven at 80°C for 15 minutes to obtain polyether polyurethane-graphene oxide foam.

[0039]2) Accurately weigh 300 mg of multilayer graphene oxide solids with an analytical balance and place them in 1000 ml of ultrapure water for ultrasonic dispersion. The ultrasonic power is 450 W, and the speed of the stirring rod is set to 100 rpm. Stir once in half an hour, and...

Abstract

The invention discloses a biological filter device and a working method thereof for treating trace antibiotic waste water, belonging to the technical field of sewage treatment. It includes an outer cylinder and an inner cylinder. The inner cylinder is made of transparent material, and the inner cylinder is nested inside the outer cylinder. The outer cylinder and the inner cylinder form a two-way degradation device. The waste water containing antibiotics is firstly absorbed by chlorella and then partially processed under the light of the light source. It is degraded, then enters the inner cylinder, is completely contacted by the polyether polyurethane-graphene composite foam filler with chlorella and microbial symbionts, and is discharged from the outlet pipe after being completely oxidized and degraded. The structure design is reasonable, green and environmentally friendly, low energy consumption, and can efficiently remove antibiotics in wastewater by combining photodegradation and biodegradation, and has a good application prospect.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a biological filter device for treating trace antibiotic waste water and a working method thereof. Background technique [0002] Antibiotics are substances produced by microorganisms that inhibit or destroy the growth of bacteria, protozoa and fungi. At present, antibiotics are mainly used for the treatment of human diseases and the prevention and treatment of animal and plant diseases in livestock and poultry farming and plant cultivation. In China, about 210,000 tons of antibiotics are produced every year, 90% of which are mainly used in domestic agriculture and drug treatment, and the remaining 10% are exported abroad. Antibiotics are mainly divided into β-lactams, macrolides, tetracyclines, quinolones and sulfonamides. [0003] Antibiotics cannot be completely utilized by the human body or other organisms. Most drugs can maintain their original structur...
