Description
Technical field
The present invention relates to water purification agent field, more particularly, to a kind of preparation method of biological water purification agent.
Technical background
The people that China has 82% drinks shallow well and river, and wherein severe water pollution bacterium exceedes accounting for for sanitary standard
75%, by the drinking water population about 1.6 hundred million of Organic Pollution.For a long time, people think that running water is safety and sanitation always
, still, because water pollution, running water of today can not be hygienic at last.One investigation display, in whole world running water
In, the chemical pollutant measured has as many as 2221 kinds, and some of which confirms as carcinogenic substance or promotees cancer thing.Mark is drunk from running water
The methods of standard is seen, Chinese to be still in reduced levels, and running water is only capable of using precipitation, filtering, chlorination, by river or underground
Water is simply processed into drinkable water.Running water chlorination can be killed effectively except germ, while can also produce more halogenated hydrocarbon compound,
The content of these chlorinated organics is multiplied, and is the maximum root for causing the mankind to suffer from various human primary gastrointestinal cancers.Water pollution is by being harmful to
Chemical substance causes the use value of water to reduce or lose, and pollutes the water of environment.Acid, alkali, oxidant in sewage, Yi Jitong,
The organic poison such as the compounds such as cadmium, mercury, arsenic, benzene, dichloroethanes, ethylene glycol, aquatile can be poisoned with poison, influence drinking water source, wind
Scenery and landscape.The oxygen in water is consumed when organic matter in sewage is decomposed by the microorganisms, the life of aquatile is influenceed, is dissolved in water
After oxygen depletion, organic matter carries out anaerobic digestion, produces the offensive gases such as hydrogen sulfide, mercaptan, water quality is further deteriorated.
Microorganism has the characteristics of individual is small, metabolism is vigorous, distribution is wide, quantity is more, also with powerful capacity of decomposition,
Their activity ensures the material circulation of the ecosystem, purifies the ecosystem, coordinates the ecological balance, is ground based on microorganism
The probiotics of hair is nontoxic, have no side effect, noresidue and secondary pollution, does not develop immunity to drugs, and can effectively improve cultivation
Ecological environment, the ecological balance is maintained, the immunity of enhancing cultivation object, reduces the generation of disease.Therefore, it is net to carry out biological water quality
Agent has higher economic value and ecological significance.
Technology on biological water purification agent has many methods, and prior art is as authorized public number
The B of CN 101935105 Chinese invention patent, discloses a kind of microorganism water treatment agent in culturing water and its preparation side
Method, the inventive method have and prepared simply by the use of the activation montmorillonite particle for being fixed with bacillus coagulans as water purification agent
Feature, but the inventive method is only using montmorillonite particle as adsorbent, using bacillus as degradation product, it is only capable of degrading organic big
Molecule, with deodorization, antibacterial, absorption ability, it can not nitrify, be photosynthetic, drop ammonia nitrogen, it is impossible to reducing heavy metal in polluted water
The content of ion, thus it is limited the effect of it purifies water, and promotional value is little.
The content of the invention
The purpose of this method is to provide a kind of preparation method of compound, efficient biological water purification agent.
Strain used in the inventive method and its bought enterprise are：Rhodopseudomonas palustris, bacillus subtilis, He Beihan
Genie et Environnement of Tang；Bacillus licheniformis, Shandong Lv Long Bioisystech Co., Ltd；Streptococcus lactis, Shandong Piao is just
Bio tech ltd；COD degradation bacterium, Guangzhou Ran Yi bio tech ltd.
The present invention is directed to the problem of being mentioned in background technology, and the technical scheme taken is：The preparation of biological water purification agent
Method, including：Activation, load, extract flocculation activity material, prepare nano-sized iron oxide, compounding, specifically including following steps：
Activation：Gangue is put into pulverizer and crushed, 35-65 mesh sieves are crossed, by colliery powder through 780-800 DEG C of calcination activation 2-
3 hours, obtain thermal activated coal gangue support samples；The strong endothermic reaction and dehydration occur in high-temperature calcination process for gangue
Reaction, and discharges certain activity, volumetric expansion after gangue is fired, its surface and is internally formed substantial amounts of micropore, together
When there is the architectural feature of micropore and mesopore, there is strong ion exchangeable and larger adsorption capacity, thermal activated coal gangue by
There is strong, renewable, the inexpensive advantage of adsorption capacity in it, can be as the good carrier of microorganism species immobilization；
Load：The accurate active coal gangue carrier for weighing 10-15 parts, is put into iodine flask, the moist heat sterilization at 120-121 DEG C
20-25 minutes, the composite bacteria liquid of 3-5 parts is added, is put into shaking table, it is small with 40-60r/min rotating speeds shake 2-2.5 at 30-33 DEG C
When, unnecessary bacterium solution is then poured out, the glutaraldehyde water solution that 40-50 parts concentration is 2-2.5% is added, 24-36 is crosslinked at 2-4 DEG C
Unnecessary glutaraldehyde is poured out after hour, with sterile water washing 4-6 times, so far composite flora immobilization is completed to produce load of microorganisms net
Water stone flour；Activated carrier mainly handles waste water by physical absorption and chemisorbed, physical absorption be mainly reflected in gangue with
Intermolecular attraction effect between contaminant molecule, this effect is by porous and the surface area decision of gangue, this absorption
Without selectivity, thus there is certain Adsorption ability to various pollutants；And chemisorbed is primarily due to gangue
