Description
Technical field
The present invention relates to microalgae purify sewage pretreatment technology field, specifically, be it is a kind of be used for both culturing microalgae
Wastewater from pig farm ozone treatment method.
Background technology
With the fast development of the growth, growth in the living standard and social economy of population, the mankind are to animal protein
Demand is also stepped up.Solve the shortage of human animal's property albumen crucial by cultivation.Development livestock and poultry and aquaculture are to solve animal
Property albumen shortage important measures.Waste gas, waste liquid and the waste residue produced during scale animal and poultry cultivation, to the ecology on periphery
Environmental protection often results in very big pressure.Aquaculture wastewater and fluid bodily thing are that intensive livestock and poultry farms pollutant is innoxious
The difficult point of processing.Main polluter is nitrogen, phosphorus and organic matter of high concentration etc. in hoggery sewerage.Wastewater from pig farm is straight
It is discharged to surrounding body, it will cause natural water serious eutrophication.How pig farm is purified, increasingly become Large-scale pig farm
The restraining factors of sustainable production.It is scale pig-breeding to develop reusable edible, sewage disposal technology efficiently, inexpensive
The important measures of sustainable development.
Microalgae is biological as the low photoautotrophy type of a class, and species is enriched, photosynthetic efficiency height tool, has growth and breeding rapid,
Energy efficient absorption utilizes the nutritive salt such as the nitrogen phosphorus in water body, and cytotrophy value is high (to be rich in albumen, it is necessary to fatty and vitamin etc.
Active material), it is widely used (feed addictive, bioenergy, extract physiological activator) the features such as.Opened using wastewater from pig farm
Microdisk electrode is opened up, the dirty water decontamination handles and micro algae biomass production can be undoubtedly realized simultaneously, the sustainable and resource of environment is realized
Recycle.Therefore wastewater from pig farm purification coupling micro algae biomass production just turns into the new think of of wastewater from pig farm recycling treatment
Road.
However, also there are protozoan and bacterium etc. in wastewater from pig farm, it is directly used in microdisk electrode and is easily caused culture
Failure, the colourity of sewage and the suspended particulate contained influence the permeability of light wherein, the photosynthesis of unfavorable microalgae, therefore pig
Field sewage needs necessarily to be filtered, sterilized and drifted processing before being used for microdisk electrode.The sterilization bleaching of current sewage is effective
Chlorine method (such as using bleaching powder, sodium hypochlorite etc.) and Ozone.Available-chlorine method needs to add chemical reagent thereto, can increase pre- place
Cost and link are managed, while reducing the part nitrogen in sewage, the utilization rate of phosphorus.Ozone (O3) super oxygen is also known as, it is oxygen (O2)
Allotrope, at normal temperatures, it is a kind of light blue gas for having an off-odor.At normal temperatures and pressures, less stable, can
Voluntarily it is decomposed into oxygen.Ozone, which has, is usually used in sterilization in Strong oxdiative ability, industrial and agricultural production, removing toxic substances is fresh-keeping, bleaching, deodorization
Etc. purposes, the strong oxidizing property of ozone is organic in oxidable unnecessary or poisonous inorganic matter, such as cyanide, oxidation removal water
Thing, particularly microorganism are difficult to the organic matter degraded, such as surfactant, BOD and COD in reduction water, On Inactivation of Virus In Water, thin
Bacterium, the clean harmless disinfectant of generation.It is widely used in drinking water sterilization, Treated sewage reusing purification, sewage disposal, greenhouse soil to disappear
Poison, swimming-pool water processing and Hospital Sewage Treatment.
At present, ozone processing sewage generally uses aeration in production, and will contain ozone-air and be passed through in sewage.But ozone
Dissolubility in water body is not high, and 0.494 volume ozone can only be dissolved under 1 volume of water normal temperature and pressure.Traditional aeration ozone
Processing sewage has that gas-liquid contact face is small, and ozone utilization rate is low, it is necessary to the drawbacks of long period is aerated, treatment effect in the short time
It is not good.Meanwhile, the bactericidal effect of ozone is relevant with temperature and humidity, especially humidity, and relative humidity is less than 45%, and ozone is to sky
Suspension microorganism is almost without killing action in gas.Just gradually strengthen at 60%, maximum is reached in humidity 95%.Therefore
It is that lifting ozone is sterilized in sewage to improve ozone treatment method, is detoxified, bleaching, the important channel of the application such as deodorization.And on
The method of this lifting ozone sewage treatment effeciency yet there are no report.
The content of the invention
The purpose of the present invention is that there is provided a kind of ozone for being capable of efficient process wastewater from pig farm for deficiency of the prior art
Processing method, the method for making the wastewater from pig farm after processing be used directly for both culturing microalgae improves ozone treatment effeciency, reduces smelly
