Anaerobic bacteria are a kind of bacteria that grow better under anaerobic conditions than under aerobic conditions, but cannot grow on the surface of solid culture medium with air (18% oxygen) and/or 10% carbon dioxide concentration.
Aerobic bacteria are also called oxygen-absorbing bacteria. Bacteria with complete respiratory chain, including superoxide dismutase (SOD) and catalase, must live in aerobic environment. Growth and reproduction in aerobic environment, oxidation of organic or inorganic substances, aerobic respiration with molecular oxygen as the final electron acceptor.
Biochemical treatment is often used in sewage treatment engineering. The so-called biochemical treatment is to cultivate microorganisms. Based on the principles of biological purification and fluid mechanics, microbial generator can effectively remove soluble organic matter and some insoluble organic matter from wastewater by using the life activities of microorganisms. It has advanced technology, stable performance and safe use, and is especially suitable for various wastewater (sewage) treatment and micro-pollution treatment. It has the following advantages:
1. The equipment adopts three-stage generation, alternate operation, step-by-step derivation and logarithmic growth technology, so that the microbial density generated by the generator can reach as high as 1.8× 1020CFU/ml. After high-density microorganisms are released into the biochemical pool, the biomass in the pool rapidly increases to more than 2.0× 104mg/L, which can completely decompose pollutants in sewage into CO2.
Second, the equipment is an ideal biological sewage treatment equipment, which can produce different kinds, different bacteria, different temperatures and different microorganisms with different sewage treatment needs according to different types, different properties and different environments, and is especially suitable for urban domestic sewage, rural domestic sewage, medical sewage, industrial wastewater, livestock and poultry breeding wastewater, high-salinity wastewater, high-ammonia nitrogen wastewater, toxic and harmful wastewater, heavy metal wastewater, landfill leachate and other wastes (sewage).
The equipment can also be directly matched with old sewage treatment projects such as contact oxidation method, AB method, A/O method, oxidation ditch and SBR. It can achieve various purposes such as upgrading and expanding sewage treatment, reducing sludge, removing nitrogen and phosphorus, and reusing reclaimed water. Do not change the sewage treatment process and civil engineering. The equipment can also be used in landscape, rivers, lakes, rivers, salt lakes, bays, land and other fields to remove micro-pollution and protect the public environment.
3. The microbial generator produces high-density dominant microbial flora, which can quickly eat pollutants and sludge in sewage without peculiar smell. It does not need sludge dehydrator, sludge conveyor, mud cake transporter, waste gas treatment equipment and high-power blast aeration equipment. Compared with the traditional method, the energy consumption of activated sludge method is 1/8, and the equipment investment can be saved by 70%. It can also be operated in shallow pools to treat sewage.
4. The high-density microbial flora generated by this equipment can rapidly reduce the biological oxygen consumption (BOD), chemical oxygen consumption (COD) and suspended matter (TSS) in the sewage after the sewage enters the treatment tank through the jet, which has a strong function of nitrogen and phosphorus removal. It can also convert five kinds of water into more than three kinds in a very short time, eliminate the odor in sewage within 7 days, and eat about 50% sludge in sewage within 10 day.
Using this equipment to treat sewage has no worries about sludge bulking and is not limited by the age and education of operators. Convenient management, safety and reliability.
5. With the emergence of more and more high-density microbial flora, the biological oxygen consumption (BOD) in sewage is less and less, and a large number of microorganisms lose their survival energy due to lack of BOD and become carbon dioxide and water. Non-extinct microorganisms can also be used as bait for fish and plankton, thus forming a benign ecological treatment and purification process, without odor, sludge and secondary pollution, creating a green environment.
6. Traditional sewage biochemical treatment methods are affected by climate and water temperature changes. When the temperature decreases 10℃, the enzymatic reaction speed of microorganisms decreases by 1-2 times. Climate leads to insufficient microbial activity and poor sewage treatment effect, which not only threatens the sewage treatment plants in the north, but also challenges the sewage treatment plants in the south in winter. The patented bio-generator produced by Guizhou Great Wall Environmental Protection Technology Co., Ltd. completely solved this problem. After the high-concentration microbial flora produced by the bio-generator is released into the aeration tank, its biomass information speed reaches more than 2.0× 104mg/L, which makes the biological concentration in the aeration tank increase by 10 times compared with the activated sludge, and fills the technical problems of insufficient biomass and poor sewage treatment effect caused by low water temperature.
7. Traditional biochemical methods are used to treat wastewater with high concentration, high ammonia nitrogen, high salt content, toxicity and heavy metals. Due to the survival and small number of microorganisms in these wastewater, the effluent quality after sewage treatment is poor and the effect is unstable, so it is difficult to meet the discharge standards. Microbial generator completely solved this problem in a unique way. The generator can continuously send the generated high-concentration microbial flora of 1.8× 1.020 cfu/ml into the aeration tank, which increases the biomass of 10 times more than other sewage treatments, and the powerful microbial flora accelerates the degradation and digestion of pollutants in sewage. At the same time, aeration and oxygen supply significantly accelerate the decomposition of pollutants into CO2 and H2O, and nitrate and sulfate become nutrients for microbial growth, leading to further derivation of microorganisms. Even under the influence of cold weather, low temperature and impact load, under the inhibition of high concentration, high ammonia nitrogen, high salt content, toxicity and heavy metals, it is impossible to prevent microbial armies from competing with each other, forming a strong sewage treatment lineup, degrading and digesting pollutants in sewage, and finally realizing it.
Eight, the traditional river management can not be separated from the dam opening, water interception, dredging and other treatment processes, the project cost is large, the construction period is long, and the amount of silt is large. Biogenerators are directly installed in the upstream of micro-pollution sources such as landscapes, rivers, lakes, rivers, saltwater lakes, bays and land. Cut off and block the pollution source from the source, and achieve thorough treatment by degrading pollution, eating sludge, removing odor, removing phosphorus and nitrogen, etc. It provides reliable equipment for micro-pollution control.
