Problems solved by technology

[0003] Most of the existing treatment methods for antibiotic wastewater are conventional aerobic, anaerobic or aerobic plus anaerobic biological treatment methods. Not only the treatment process is complicated and the cost is high, but also the residues are relatively heavy due to the resistance of antibiotics. High, after treatment can not fully meet drinking water standards

Embodiment １

[0026] Embodiment 1: A device for treating antibiotic wastewater based on iron-carbon micro-electrolysis method provided by the present invention mainly includes:

[0027] The iron-carbon micro-electrolysis reactor, packing area, aeration area, and water bath area, among which the packing area and aeration area are collectively referred to as the reaction area. The filling area 2 is evenly stacked with iron-carbon materials, the aeration area and the filling area are separated by a porous partition 3, and a perforated aeration hose 6 is evenly laid under the porous partition to supply oxygen to the reaction area, enhance micro-electrolysis, and It acts as agitator to prevent iron-carbon agglomeration. The iron-carbon micro-electrolysis reactor is composed of a shell 7 and a top cover 1, the upper part of the side wall is provided with a water inlet, and the lower part of the side wall is provided with a water outlet. The outside of the reaction zone is the water bath area, wh...

Embodiment ２

[0029] At room temperature, it is taken from laboratory water, 20mg / l sulfamethazine solution, the initial pH is 7.80.

[0030] Using the device described in Example 1, adjust the pH of the raw water to 2 with 10% hydrochloric acid, then pass the antibiotic waste water with a pH of 2 into the iron-carbon micro-electrolysis reactor, and at the same time aerate the reactor to provide the reaction area with oxygen. After reacting for a certain period of time, the reflux device in the reactor is turned on to circulate the waste water in the reactor to improve the mass transfer conditions of the system. After the water stays in the reactor for 8 hours, the water comes out. After treatment, the removal rate of sulfamerazine reached 87%, the removal rate of TOC reached 50%, and the pH was 5.8.

Embodiment ３

[0032] At normal temperature, it is taken from the laboratory distribution water, 20mg / l penicillin G sodium solution, the initial pH is 7.

[0033] Using the device described in Example 1, adjust the pH of the raw water to 2 with 10% hydrochloric acid, then pass the antibiotic waste water with a pH of 2 into the iron-carbon micro-electrolysis reactor, and at the same time aerate the reactor to provide the reaction area with oxygen. After reacting for a certain period of time, the reflux device in the reactor is turned on to circulate the waste water in the reactor to improve the mass transfer conditions of the system. After the water stays in the reactor for 8 hours, the water comes out. After treatment, the removal rate of penicillin reached 95%, the removal rate of TOC reached 54%, and the pH was 5.6.

Abstract

The invention discloses an experimental device and method for treating antibiotic wastewater through an iron-carbon micro-electrolysis method. An iron-carbon micro-electrolysis device comprises a top cover, a stuffing region, a multihole plate supporting layer, a heating stick, a temperature controller and an aeration pipe. The invention further discloses a method for treating the antibiotic wastewater by using the device. The method comprises the following steps: injecting the antibiotic wastewater into an adjustment pool, adjusting pH to be 2.0 to 4.0, then injecting the antibiotic wastewater into a reactor through a water inlet of an iron-carbon micro-electrolysis reactor, and enabling a fan to blow air through an air inlet for aeration, wherein discharged water flows back into the reactor from the water inlet through a backflow pump; enabling the water to stay for 4 to 8 hours, and then discharging the water from a water outlet, thus completing treatment of the wastewater. The experimental device has the advantages of good treatment effect, long service life, simple operation and low cost.

Description

technical field [0001] The invention belongs to the technical field of wastewater treatment, and in particular relates to an experimental device and method for treating antibiotic wastewater. Background technique [0002] With the rapid development of my country's chemical industry, various new chemical products are used in all walks of life, and medicine is one of the major categories. The serious environmental pollution problems caused by this are specifically manifested in: the concentration of organic pollutants in wastewater High, stable structure, poor biochemical properties, conventional technology is difficult to achieve discharge standards. Antibiotics, as a large class of commonly used drugs in production and life, have been put into use in large quantities, and there are even abuses. Improper discharge and metabolism of humans and animals lead to the emergence of antibiotics in water bodies and soils, which have a negative impact on the water ecological environment...
