Abstract
The invention discloses a microorganism nutrient agent for sewage treatment. The nutrient agent is prepared from the following raw materials in percentage by mass: 15-70% of potato powder, 10-20% of cane sugar, 5-40% of cellulose, 0.5-2% of monopotassium phosphate, 0.5-2% of sodium ammonium, 0.5-3% of ammonium sulfate, 0.5-2% of magnesium sulfate heptahydrate, 0.5-2% of magnesium nitrate, 0.5-2% of calcium chloride, 0.5-4% of ferrous sulfate, 2-15% of peptone and 0.5-8% of oleic acid. As starch and cellulose are taken as main components and are combined with a great amount of organic and inorganic elements, the microorganism nutrient agent can be used for acclimating microorganisms in living wastewater and petrochemical wastewater and used for adjusting microorganism death caused by various insufficient nutrition components or ratio disorder, and has the advantages of being low in price, easy to obtain, free of pollution and rich in nutrition component.
Description
Technical field
The present invention relates to the applied technical field of sewage disposal microorganism culturing breeding domestication, particularly relate to the agent of a kind of sewage disposal microbial nutrition.
Background technology
In treatment process for sewage in oil field, petroleum-type and suspended substance generally adopt the method process of oil removal-coagulation-filtration, but it is up to standard to adopt the method that the part index number of recovered water can be caused to be difficult to, especially the CODcr of condensed oil sewage, polymer produced water, high saliferous recovered water can be seriously higher, and compliance rate is only about 50%.Other industry mostly adopts biochemical treatment process to solve the too high problem of COD value at home, and petroleum industry also can use for reference this method.Employing microbial process is disposed of sewage, and crude oil can be separated more thoroughly like this, decompose, and not only cost is low, easy and simple to handle, good degrading effect, effectively can also reduce the pollution that chemical treatments causes, preserve the ecological environment [2].These advantages also cause microbial process to become the main flow of present stage disposing polluted water in oil technology above.Microorganism sewage water treatment technology at home each oil field is obtained for and uses widely, and achieves good effect.Microorganism treating sewage first cultivates special flora, flora forms dominant microflora by hydration, breeding, decomposition and competition, the effect of recycling dominant microflora carries out biological degradation to the organism (hydro carbons, lipid etc.) in sewage, organism is converted into new biomass cells and simple inorganics, finally reaches the object of organics removal.In recent years, along with the increase of the production-scale expansion of petroleum chemical enterprise and production kind, in waste water, the kind of hazardous and noxious substances and biological inhibition material is also increasing, and mostly is Persistent organic pollutants.Adopt traditional activated sludge process to be difficult to adapt to the water quality characteristics of present stage petrochemical wastewater, lot of domestic and international oil field all starts to adopt microbial process to process oilfield sewage, brings good economic benefit to oil field.
The microbiobacterial agent being applied to ecological environmental protection and prevention and cure of pollution by one or more from nature separation and purification, to be formed by the microbial strains (strain) of nature or artificially breeding (without genetic modification).In biochemical processing procedure of sewage, the biological reinforcing technology adding microbiobacterial agent accelerating biochemical treatment system toggle speed, the treatment effect improving system and capacity of resisting impact load, improvement all shows huge potentiality in the degradation capability of certain specific pollutants etc.
Summary of the invention
Based on the problem existing for above-mentioned prior art, the invention provides the agent of a kind of sewage disposal microbial nutrition, can sewage disposal be used for, promote microorganism active, improve the treatment effect to sewage.
For solving the problems of the technologies described above, the invention provides the agent of a kind of sewage disposal microbial nutrition, this nutrition agent is made up of following raw material by mass percentage: mealy potato 15 ~ 70%, sucrose 10 ~ 20%, Mierocrystalline cellulose 5 ~ 40%, potassium primary phosphate 0.5 ~ 2%, microcosmic salt 0.5 ~ 2%, ammonium sulfate 0.5 ~ 3%, bitter salt 0.5 ~ 2%, magnesium nitrate 0.5 ~ 2%, calcium chloride 0.5 ~ 2%, ferrous sulfate 0.5 ~ 4%, peptone 2 ~ 15% and oleic acid 0.5 ~ 2%.
Sewage disposal microbial nutrition of the present invention agent, because main ingredient is starch and Mierocrystalline cellulose, and in organic and inorganic elements cooperation in a large number, sanitary wastewater can be applied to, in petrochemical wastewater microorganism domestication and regulate microorganism because various nutrition composition is inadequate or out of proportion microbial death that is that cause, have inexpensive, be easy to get, pollution-free, the advantage that nutrition composition is abundant.
Embodiment
Be clearly and completely described the technical scheme in the embodiment of the present invention below, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on embodiments of the invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to protection scope of the present invention.
The embodiment of the present invention provides a kind of for the microbial nutrition agent in petrochemical wastewater treatment system.This nutrition agent can cultivate the microorganism in petrochemical wastewater treatment system, makes it to reach system within a short period of time and normally runs required microbe species and quantity.Nutrition agent composition of raw materials of the present invention and weight percent as follows: mealy potato 15 ~ 70%, sucrose 10 ~ 20%, Mierocrystalline cellulose 5 ~ 40%, potassium primary phosphate 0.5 ~ 2%, microcosmic salt 0.5 ~ 2%, ammonium sulfate 0.5 ~ 3%, bitter salt 0.5 ~ 2%, magnesium nitrate 0.5 ~ 2%, calcium chloride 0.5 ~ 2%, ferrous sulfate 0.5 ~ 4%, peptone 2 ~ 15% and oleic acid 0.5 ~ 2%.This microbial nutrition agent can select the nutrition agent in aforementioned proportion according to composition in different waste water, can sanitary wastewater be applied to, in petrochemical wastewater microorganism domestication and regulate microorganism because various nutrition composition is inadequate or out of proportion microbial death that is that cause.
Below in conjunction with specific embodiment, nutrition agent of the present invention is described further.
