Embodiment 1

[0046] Example 1 A kind of adsorption-membrane separation coupling device for removing antibiotics in wastewater

[0047] See attached figure 1 , the present invention is used to remove the adsorption-membrane separation coupling device of antibiotic in waste water, and described device comprises pretreatment pool 1, adjustment pool 2, reaction pool 3, clean water pool 4 and the pipeline that connects thereof; Said pretreatment Pool 1, regulating pool 2, reaction pool 3, and water purification pool 4 are connected in series through pipelines;

[0048] A first fluid circulation pump 16 and a first switch valve 7 are provided on the connecting pipeline between the pretreatment tank 1 and the regulating tank 2; There is a second fluid circulation pump 18 and a second switch valve 20; a negative pressure water pump 19 and a third switch valve 21 are provided on the connecting pipeline between the reaction tank 3 and the clean water tank 4, and each tank bottom is provided with T...

Embodiment 2

[0057] Embodiment 2 Utilizes the method for treating wastewater with the adsorption-membrane separation coupling device for removing antibiotics in wastewater of the present invention

[0058] A wastewater treatment method for removing antibiotics with an adsorption-membrane separation coupling device, including:

[0059] S1. Add the waste water that has been coarsely filtered through the grid into the pretreatment tank 1; the antibiotic content in the initial waste water is 700 mg / L, and the pH is 8;

[0060] S2. Add flocculants and coagulants to the wastewater in the pretreatment tank 1; the input amount per liter of wastewater is: 100 mg inorganic aluminum salt and 2 mg polyacrylamide. After the upper liquid is clarified, turn on the first fluid circulation pump 16 and the first Switch valve 17 to make the supernatant flow into the regulating tank 2;

Abstract

The invention belongs to the field of wastewater treatment, and in particular relates to an adsorption-membrane separation coupling device for removing antibiotics in wastewater and a wastewater treatment method. The device includes a pretreatment pool, a regulating pool, a reaction pool, a water purification pool and pipes for connection thereof; the pretreatment pool, the regulating pool, the reaction pool, and the water purification pool are connected in series through the pipes. The operation steps of the method include: putting a pretreatment agent into a pretreatment tank to pretreat the wastewater; transferring to a regulating tank to adjust the pH and temperature of the supernatant; transferring to a reaction tank to add adsorption materials and aeration to carry out Reaction; transfer the reaction liquid into the clear water pool; when the operation is stopped, turn off the power switch and other corresponding valves. The device of the invention has the advantages of simple operation, convenient cleaning, etc., can simultaneously solve the problems of high energy consumption for nanofiltration and reverse osmosis membrane separation, high price and difficult recovery of adsorbent, and greatly improves the removal efficiency of antibiotics in waste water.

Description

technical field [0001] The invention belongs to the field of wastewater treatment, and in particular relates to an adsorption-membrane separation coupling device for removing antibiotics in wastewater and a wastewater treatment method. Background technique [0002] Antibiotic wastewater is a type of organic wastewater containing residual antibiotics and intermediate products produced during the production process. This type of wastewater has complex components and contains a variety of refractory substances, including high organic matter and suspended matter, a wide pH range, and color and Odor, with strong biological toxicity, the domestic use of antibiotics is large, and the abuse is serious. After antibiotics are absorbed by the body, they are not fully absorbed, and about 60%-90% are excreted with animal feces in the form of drug prototypes or primary metabolites. With the extensive migration in water bodies, antibiotics appear in soil and sediment , surface water, grou...
