Abstract
The invention provides a method for removing antibiotic and hormone in livestock and poultry breeding wastewater and belongs to the technical field of water pollution control. The method comprises the step of carrying out aeration while the ultrasonic treatment is carried out by adopting an ultrasonic processing technology. The invention has the advantages as follows: compared with biological treatment and other traditional methods, the method is gentler in reaction conditions and short in treatment time, and the purpose of efficient treatment is realized; the ultrasonic chemical reaction in a reaction system is strengthened by the aeration; through the ultrasonic treatment, an antibiotic and hormone structure is quickly and effectively degraded, the chemical nature of the antibiotic and hormone structure is changed, and the biotoxicity of the antibiotic and hormone structure is reduced; and equipment is simple and is easily to obtain, running and operating methods are simple, the investment is less, and the energy is saved.
Description
Technical field
The present invention relates to the wastewater treating technology field, particularly relate to a kind of method of removing microbiotic and hormone in the livestock breeding wastewater.
Background technology
In intensification, scale animal and poultry cultivation process; Though microbiotic and hormone etc. help reducing livestock and poultry; But along with scientific-technical progress, people find abuse, excess gradually, arbitrarily use microbiotic, hormone as fodder additives, and breeding environment has been caused serious negative consequences.After microbiotic and hormone get into animal digestive tract with feed; Entering animal blood circulation in short period of time, final most medicine filters through kidney and excretes with urine, with the form entering environment of waste water; Polluted source and soil; Even possibly be converted into the precursor of environmental hormone or environmental hormone, thus the eubiosis directly destroyed, and then threaten human healthy.
Microbiotic and hormone because of itself having the toxicity to anaerobion and aerobic microbiological, although traditional biological treatment can be removed part microbiotic and hormone through biological degradation, act on limited as the Persistent organic pollutants in the waste water.
Summary of the invention
The object of the present invention is to provide a kind of method of removing microbiotic and hormone in the livestock breeding wastewater, this method is handled the waste water of livestock poultry that ultrasonic technology is applied to contain microbiotic and hormone.As one of high-level oxidation technology, the cavitation effect that UW produces has good degradation effect to hardly degraded organic substance.The ultrasonic degradation organic pollutant has two mechanism, i.e. direct the break hydroxyl radical free radical oxygenolysis of moment formation of pyrolytic decomposition and cavitation bubble in the cavitation bubble.UW is applicable to the removal of the hardly degraded organic substance in the waste water, and can effectively reduce the bio-toxicity of waste water.
The present invention is a kind of to remove the method for microbiotic and hormone in the livestock breeding wastewater, realizes through the following step successively:
(1) using mass ratio concentration is pH value to 8.0 ~ 9.0 that 1% sodium hydroxide solution is regulated waste water;
(2) probe with the sonde-type ultrasonic generator is immersed in 1 ~ 1.5cm under the waste water liquid level; The adjustment ultrasonic power is to 120W ~ 960W; Power density is 480 ~ 3840W/L, carries out ultrasonication 3min, uses aerator as 10:1 ~ 60:1 condition waste water to be carried out aeration with GWR simultaneously.
After UW radiation and aeration are handled; Liquid-phase chromatographic analysis is carried out in sampling; Detect duomycin, tsiklomitsin, terramycin and olaquindox concentration in the waste water; The result shows, handle with the inventive method to contain microbiotic and hormone waste water, to duomycin, tsiklomitsin, terramycin and olaquindox clearance in the waste water all more than 30%.
Advantage of the present invention is, ultrasonic applications in the industrial treatment that contains microbiotic and hormone waste water, compared with traditional method such as biological treatment, and the reaction conditions milder of the inventive method, the treatment time is short, has realized efficient processing intent; Aeration reinforcing the sonochemistry reaction in the reaction system.Through effective fast degraded microbiotic of ultrasonication and hormone structure, change its chemical property, reduce its bio-toxicity; Present device is simple and easy to, and the operation method is simple, invest less, energy-conservation.
Embodiment
Embodiment 1:
Using mass ratio concentration is the pH value to 8.5 that 1% sodium hydroxide solution is regulated waste water; The sonde-type ultrasonic variable amplitude bar is goed deep into about 1 ~ 1.5cm under the liquid level, and the adjustment ultrasonic power is to 600W, and power density is 2400W/L; Ultrasonication 3min; Use miniature aerator to carry out aeration at 10: 1 with GWR simultaneously, detect duomycin, tsiklomitsin, terramycin, olaquindox through gas chromatographic analysis, its clearance reaches 69.39%, 46.58%, 53.94%, 64.52% respectively.
Embodiment 2:
Get the pH value and be about 8.7 the natural pond liquid that contains multiple microbiotic and hormone; The sonde-type ultrasonic variable amplitude bar is goed deep into about 1 ~ 1.5cm under the liquid level, and the adjustment ultrasonic power is to 300W, and power density is 1200W/L; Ultrasonication 3min; Simultaneously carry out aeration at 60: 1 with GWR, detect duomycin, tsiklomitsin, terramycin, olaquindox through gas chromatographic analysis, its clearance reaches 68.4%, 30.8%, 30.9%, 45.7% respectively.
