Abstract
The invention discloses a method for removing tetracycline in water based on a high-rate algae pond. The tetracycline is degraded under illumination by utilizing an algal-bacterial symbiotic system in the high-rate algae pond. The method specifically comprises the following steps: inputting wastewater to be treated into the high-rate algae pond by utilizing a peristaltic pump, starting a stirrer and fluorescent lamps with the power of over 15W on an annular corridor, and degrading the tetracycline by the algal-bacterial symbiotic system in the high-rate algae pond when the temperature is 20-30 DEG C, the pH value is 6-7.5 and the algae concentration is 2*10<9>cells/mL. The reaction time is prolonged, the degradation rate of the tetracycline is increased, and outer drainage which meets the requirement can be finally realized.
Description
Technical field
The present invention relates to the method for tsiklomitsin in a kind of Using High-Rate Algae Pond degradation water, provide a kind of environment optimization, efficient, cheap photochemistry ecology to send out the technology of repairing polluted-water.
Background technology
Tsiklomitsin is to have the synthetic large class spectrum antibacterials of anti-bacteria albumen.Along with the development of intensive culture industry, tsiklomitsin medicine gets more and more for culture fishery as fodder additives, and raiser directly applies feed at the water surface, and the feed a part that contains medicine is not eaten by animal and directly entered in water.Therefore in different water bodys, certain density tetracycline medication detected, caused certain harm to the ecotope of receiving water body.
Using High-Rate Algae Pond (HRAP) is a kind of improved form growing up on traditional stabilization pond basis, utilize algae proliferation to produce to be conducive to the environment of microorganism growth and breeding, form the system of algae-bacterium symbiosis more closely, reach the removal that organic carbon, pathogenic agent, nitrogen phosphorus etc. are polluted.Compared with traditional two stage biological treatment technology, Using High-Rate Algae Pond has that investment is low, the feature of economic operating cost.Therefore, can utilize Using High-Rate Algae Pond to remove the tetracyclines antibacterials in water surrounding, realize the restoration of the ecosystem that is subject to tsiklomitsin polluted-water.
At present, utilize Algal to remove organism and nitrogen phosphorus in water both at home and abroad, not yet related to but Using High-Rate Algae Pond is removed to Micropollutants in cultivation class waste water.In addition; the treatment technology of other class is due to startup, maintenance management are had relatively high expectations; need professional to manage; lack the basis of long-acting operation in livestock and poultry cultivation region; and Using High-Rate Algae Pond reduced investment, the feature such as energy consumption is low, maintenance is simple, organic matter removal is high, noiseless and foul smell, water pollution control and protection of the environment to a lot of livestock and poultry of China or aquaculture area have very profound significance.
Summary of the invention
The invention provides a kind of biochemical method that can remove tsiklomitsin in water, to realize anti-microbial type medicine in environmental friendliness, ecology, efficient, cheap degradation water, be applicable to processing the waste water containing cultivation, life and the production of tsiklomitsin medicine.
A kind of method of removing tsiklomitsin based on Using High-Rate Algae Pond of the present invention:
Step 1 a kind of device of removing tsiklomitsin based on Using High-Rate Algae Pond, comprises Using High-Rate Algae Pond reactor, stirring rake, settling tank, Controlling System, peristaltic pump, storage tank.First waste water containing tsiklomitsin enter into settling tank, and peristaltic pump is transported to the water in settling tank in Using High-Rate Algae Pond reactor, is provided with rising pipe on reactor, and fluorescent lamp is installed in reactor top.The long 1m of every covering device, wide 0.2m, the degree of depth is 0.1m and 0.15m.
Step 2 enters settling tank containing the waste water of tsiklomitsin, removes suspended substance.
Step 3 is opened peristaltic pump, and waste water enters in Using High-Rate Algae Pond reactor.Open stirring rake, keep waste water to circulate in the algae pool, the temperature (25 ± 5 DEG C) when constant reaction.
Step 4 is added certain density algae in Using High-Rate Algae Pond.
Step 4 opening control system, arranges the reaction times, opens fluorescent lamp after stablizing 10min, starts to carry out the reaction of Using High-Rate Algae Pond degraded tetracycline medication, timing sampling, and measure the concentration of tetracycline medication in water.
Step 5 is when in water, tsiklomitsin medicine is lower than set concentration, stopped reaction.
With existing remove tsiklomitsin technology compared with, advantage of the present invention:
1. algae is biology more common in a kind of river, lake, cheap and easy to get, and does not produce secondary pollution, is a kind of eco-friendly vector.
2. tetracycline medication degradation rate can reach more than 90%.
3. water odorless after treatment, turbidity is very low, without secondary treatment.
4. energy consumption is low, maintenance is simple, noiseless.
5. this technique can manual operation, also can realize semi-automation and full-automatic operation.
Embodiment
Enter the waste water that contains tsiklomitsin in settling tank after 3h precipitation, the pH value of regulator solution, to 6.5-7.5, utilizes peristaltic pump to be transported in Using High-Rate Algae Pond reactor afterwards.
Step 1 is to the algae (being about 2 × 109 frustule/mL) of adding some amount in reactor, opens stirring rake and makes to keep containing tsiklomitsin sewage in Using High-Rate Algae Pond annularly flow, and flow velocity is 0.2m/s.
Step 2 is opened the temperature controller of Using High-Rate Algae Pond, makes whole reaction maintain 25 ± 5 DEG C.
Step 3 turn on lights Optimizing Control System, keeping radiant light quantum flux is 3000-4000lux, and reaction times warning howler is set, the concentration of tsiklomitsin in given time sampling monitoring waste water.
The wastewater degradation that step 4 contains tsiklomitsin when the set concentration, stops Using High-Rate Algae Pond operation, and static 15-20min, by the water-freeing arrangement supernatant liquor of draining.
Step 5, after supernatant liquor is drained, continues to carry the waste water that contains tsiklomitsin in Using High-Rate Algae Pond, carries out the reaction in next cycle.
