Novel treatment process of antibiotic wastewater electron beams

Abstract

The invention discloses a novel treatment process of antibiotic wastewater electron beams. The process is characterized by comprising the following steps of: irradiating electron beams, taking an antibiotic wastewater (500-1000mL) sample, adding 0.5%o-2%o of irradiating synergistic agent, mixing uniformly, conveying by using a tray, and irradiating by using a transmission system under the beam of an electron accelcrator; (2) carrying out coagulating sedimentation, adding 0.2%o - 0.4%o of flocculant into an irradiated water sample, quickly stirring for reacting, adding 0.4%o -0.7%o of coagulant aid, slowly stirring to form alumen ustum, standing for settling for 30 -60min, loading supernate by using a sterile bottle, conserving at temperature of 5oC -8oC, and conveying to the detection place to carry out detection analysis on the concentration of vancomycin and biological value; and (3) carrying out result analysis in which biological value is 0.5%, removal rate is 98.7%, vancomycin in mother solution is lower than a detection limit, and the biotoxicity of wastewater is obviously reduced.

Description

technical field [0001] The invention relates to a novel electron beam treatment process for antibiotic waste water, which belongs to the cross-technical field of nuclear technology application and medical sewage treatment. Background technique [0002] my country is currently one of the world's largest producers of antibiotics, but most pharmaceutical companies are small in scale and backward in production technology. The volume and quality of pharmaceutical wastewater vary greatly, making it difficult to treat. Conventional sewage treatment processes are more difficult to remove refractory pollutants such as pharmaceutical intermediates and drug residues in pharmaceutical wastewater, and incompletely treated wastewater will seriously consume oxygen after being discharged into rivers, destroying the self-purification ability of natural water bodies and causing water quality deterioration Black, eutrophication of water body, spreading germs and causing public nuisance.

AI Technical Summary

Problems solved by technology

[0005] (1) Conventional secondary biological treatment technology is difficult to achieve the standard discharge of wastewater, and advanced treatment technology is needed to further optimize the treatment effect, meet the discharge requirements, and reduce the harm of antibiotics to the environment;

[0006] (2) The commonly used advanced oxidation technologies include photocatalytic oxidation, electrocatalysis, Fenton, ozone oxidation and other processes. The catalytic efficiency of photocatalyst is not high, and the reaction time is long, which is not conducive to industrial application; the loss of electrocatalytic oxidation electrode is large, It is still in the stage of laboratory research; Fenton treatment is widely used, but excessive ferrous iron needs to be added, resulting in large sludge production and high operating costs in the later stage; ozone oxidation is selective, low solubility in water, low utilization rate, and easy Decomposition needs to be produced and used immediately, the cost is high, and the operation technology requirements are high;

[0007] (3) The current treatment technology still uses the removal rate of organic matter as the basis for discrimination, and there is a lack of testing and standards for the biological toxicity and biological potency of antibiotic wastewater treatment effluent, which seriously threatens the health and safety of the environment
