Abstract
The present invention relates to a method for deep treatment of antibiotic wastewater by using a physicochemical method, particularly to applications of combination of the electromagnetism technology and the Fenton technology in deep antibiotic wastewater treatment. The sewage treatment process combination of the present invention comprises an electromagnetic generator, Fenton, flocculation precipitation, sand filtration and oxidation adsorption. According to the present invention, the antibiotic wastewater with the COD of less than or equal to 300 mg/l and the chrominance of less than or equal to 150 times can completely achieve the first-order A discharge standard (COD is less than or equal to 50 mg/l, and the chrominance is less than or equal to 30 times), the cost of per ton of the water (labor, power and agents) does not exceed 9.00 yuan/m<3>, and the used equipment and the used agents can be purchased in the market.
Description
Technical field
The present invention relates to a kind of deep treatment method of antibiotic waste water, particularly relate to the application be combined in antibiotic waste water advanced treatment of electromagnetic technique and Fenton technology, belong to and utilize physico-chemical processes advanced treatment antibiotic waste water field.
Background technology
Antibiotic production wastewater be a class water quality and quantity change greatly, high, the bio-toxicity of complicated component, colourity greatly, containing the high-concentration organic sewage difficult to degrade of multiple inhibitory substance. the process of antibiotic production wastewater is a difficult problem of field of sewage treatment always, is difficult point and the focus of domestic and international water treatment.In recent years, through environmental worker's persevering endeavors, antibiotic waste water is administered progress to a certain degree, and at present, most microbiotic enterprise can reach sewage network emission standard substantially.In recent years, along with National Environmental situation is day by day severe, domestic a lot of area is using reaching one-level emission standard A as enterprise's standard for acceptance, and thereupon, the research for antibiotic waste water advanced treatment has become hot issue in recent years.Be summed up, have following three kinds of methods:
1, Fenton+BAF treatment process: this method flow process is simple, easy to operate, easily debugs, but investment is comparatively large, sulfuric acid, the liquid caustic soda of use are harmful influence, and BAF pond is vulnerable to impact causes fluctuation of service.
2, photocatalysis technology: clearly, but running cost is high for this method initial performances, and its light units used is easily lived by sludge paste, affects light transmission, and the method that there is no at present solves this difficult problem, studies at a low ebb.
3, three-diemsnional electrode technology: this method does not need to add medicament, reaction conditions is gentle, and oxidation capacity is comparatively strong, but electrode surface coating easily comes off, and causes operational management comparatively difficult.
Summary of the invention
Technical problem solved by the invention uses micro-vibration radiation of electromagnetic technique, centrifugation, and it makes the character of waste water change and it promotes the effect being used for degradation of organic substances or redox, substance of Fenton's reaction to make waste water obtain in-depth process.
The core of this technology is electromagnetic technique+Fenton technology, its combinationally use ensure that organism in waste water by thorough degraded and inorganic reduction material oxidized.Its mechanism of action is: the electromagnetic generator micro-vibration to waste water 3,500,000,000 times per second is irradiated, and produces instantaneous high-temperature (900 ~ 1500
oc) high pressure, makes long-chain, lopps organism chain rupture open loop; Under the effect of electromagnetic field, organic hard-degraded substance has magnetic, and solubleness reduces, and forms aggregation particle, easily flutters and catches and be easy to oxidation for oxidized dose; The effect of electromagnetic field makes the electroconductibility of waste water, specific inductivity, viscosity etc. there occurs predictable change, has added soon formation and the operating rate of ﹒ OH, and what promote Fenton's reaction is used for degradation of organic substances or redox, substance.
Advantage of the present invention is:
1, one-time investment is little: according to pilot scale measuring and calculating, process 1000 side's waste water every day, investment is no more than 8,000,000 yuan;
2, floor space is little: process 1000 side's waste water every day, floor plan is no more than 700 square metres.
3, processing efficiency is high and stable: the waste water COD after process is at about 10mg/l, and colourity is below 2 times, and try out in warp, system is highly stable;
4, running cost is low: labour cost, expenditure on power, medicament expense summation are no more than 9 yuan every cube.
Embodiment
Technical scheme of the present invention is further illustrated below by specific embodiment.
1, major equipment:
1.1 electromagnetic generator
Core machine, model is determined according to wastewater flow rate, usually customizes by process 1 side water 1KW per hour.
1.2 various tank bodies
Plain carbon stool, insulation, anticorrosion, volume was determined according to the residence time.
2, dosing
Device size is determined according to chemical feeding quantity.General, the molten concentration of ferrous sulfate is 30%, iron trichloride can with ferrous sulfate molten medicine in a tank, the molten concentration of polymerize aluminum chloride, calcium hydroxide is 10%.
3, sand filtration, absorption
The design of sandfiltration pot, adsorption and oxidation tank is with reference to " sewage water filtration process engineering legislation (HJ 2008-2010) " and " water treatment of granulated active carbon adsorption tank relates to code ", and backwashing water enters Sewage Plant internal regulation pond.
4, Chi Ti
Intermediate pool, neutralization tank, settling tank adopt skeleton construction, and internal surface is anticorrosion, Chi Ti
Volume was determined according to the residence time.
5, excess sludge
Can directly pass into sewage plant sludge concentration basin, dispose in the lump with other mud.
