Abstract
The invention provides a method for enhancing the degradability of antibiotics and hormones in livestock cultivating waste water, belonging to the technical field of water pollution treatment. In the method, waste water is treated under the action of microwaves for a short time interval (2-5 minutes), so that the structural and chemical properties of the antibiotics and hormones are changed quickly, the bio-toxicity of the antibiotics and hormones is reduced, and degradability of the antibiotics and hormones is enhanced; and equipment is simple and readily-available, a key technology is easy to grasp, an equipment running method is easy, investment is small, and energy is saved.
Description
Technical field
The present invention relates to livestock breeding wastewater and administer technical field, particularly relate to a kind of method that improves microbiotic and hormone degradability 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; Promote the growth of livestock and poultry body; But because the deficiency of the ineffective and scientific knowledge of the driving of economic interests, Supervision Measures, abuse, excess, use the phenomenon ubiquity of said medicine not according to national requirements.Along with scientific-technical progress, people find that gradually microbiotic and hormone use as fodder additives, have caused serious negative consequences to breeding environment.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.
Organic reaction under the microwave action has changed reaction kinetics mechanism, has reduced reaction activity, thereby has improved speed of response greatly.Microwave method is fast, efficient, safe because of having, be easy to control, can significantly improve characteristics such as chemical reaction rate, receives increasing attention in the environmental protection field.But still do not have up to now, about research report with the method for microbiotic and hormone degradability in the microwave treatment raising livestock breeding wastewater.
Summary of the invention
The object of the present invention is to provide a kind of method that improves microbiotic and hormone degradability in the livestock breeding wastewater, for the final removal of microbiotic in the waste water of livestock poultry and hormone provides a kind of effective treatment technology.
The present invention utilizes microwave to handle, and microwave is through changing microbiotic, the order state of hormone polar molecule and the bonding strength of chemical bond in the livestock breeding wastewater, catalyzed chemical reaction.Microwave can improve that two mechanism of microbiotic and hormone degradability are in the livestock breeding wastewater: reactant molecule has absorbed microwave energy on the one hand, has improved molecular motion speed, causes the increase of entropy; Microwave forces it to move according to the EM field mode to the polar molecule effect on the other hand, causes reducing of entropy.
The present invention is a kind of to improve the method for microbiotic and hormone degradability in the livestock breeding wastewater, realizes through the following step successively:
(1) use mass ratio concentration is that 1% HCl solution adjusting waste water ph is 4;
(2) add ydrogen peroxide 50 and ferrous sulfate, make ydrogen peroxide 50 and ferrous ion final concentration be respectively 40mg/L and 12mg/L;
(3) waste water is placed microwave device, the adjustment microwave power is to 445W, and power density is 890W/L, starts microwave generator and carries out the waste water microwave treatment 2 ~ 5 minutes.
Get that water sample and untreated effluent detect duomycin, tsiklomitsin, terramycin, olaquindox concentration in the waste water through SPE-efficient liquid phase chromatographic analysis after the microwave treatment, detect the BOD of waste water simultaneously
5, COD.The result shows, handle with the inventive method to contain microbiotic and hormone waste water, to duomycin, tsiklomitsin, terramycin, olaquindox clearance in the waste water all more than 50%, simultaneously with the BOD of waste water
5/ COD value is brought up to more than 0.3.
Advantage of the present invention is; The present invention with microwave under the pH that adjusts, power, Fenton reagent condition; Contain microbiotic and hormone waste water through processing in 2 ~ 5 minutes, improved such wastewater biodegradability, effectively change microbiotic and hormone structure, chemical property fast; Reduce its bio-toxicity, improve its biodegradability; Equipment is simple and easy to, the gordian technique easy master, and equipment operation method is simple, invest less, energy-conservation.
Embodiment
Embodiment:
Get the piggery wastewater that contains multiple microbiotic and hormone; Using mass ratio concentration is that to regulate waste water ph be 4 for 1% HCl solution; Add ydrogen peroxide 50 and ferrous sulfate, the ydrogen peroxide 50 final concentration is that 40mg/L, ferrous ion final concentration are 12mg/L, and the adjusting microwave power is that moderate heat (445 watts) was handled 2 minutes.Detected result shows that duomycin, tsiklomitsin, terramycin, olaquindox clearance reach 88.4%, 93.9%, 91.6%, 67.2% respectively in the waste water, and the wastewater biodegradability (BOD that is improved significantly
5/ COD has brought up to 0.42 by 0.20).Simultaneously COD is had certain removal effect, clearance is 46.8%.
Claims (1)
