Aerobic conditions must be achieved under aerobic conditions; anaerobic conditions can only be achieved under anaerobic conditions. Those who live between aerobic and anaerobic conditions are facultative.
Anaerobic Aerobic bacteria are a type of bacteria that grow better under anaerobic conditions than in an aerobic environment, but cannot grow on the surface of solid culture media under air (18 oxygen) and/or 10 carbon dioxide concentrations.
Aerobic bacteria are also called oxygen-breathing bacteria. They have a complete respiratory chain, contain superoxide dismutase (SOD) and catalase, and must live in an aerobic environment. They grow and reproduce in an aerobic environment. , the energy-producing metabolic process of oxidizing organic or inorganic matter, using molecular oxygen as the final electron acceptor to perform aerobic respiration.
In sewage treatment projects, biochemical treatment is often used. The so-called biochemical treatment is to cultivate microorganisms. , the microbial generator is mainly based on the principles of biological purification and fluid mechanics, using microorganisms in the life activity process to effectively remove soluble organic matter and some insoluble organic matter in wastewater. It has advanced technology, stable performance, and safe use, and is especially suitable for all kinds of waste (pollution) Water treatment and micro-pollution control have the following advantages:
1. The equipment adopts three-stage generation, alternating operation, step-by-step derivation, and logarithmic growth technology, resulting in a density of microorganisms produced by the generator as high as 1.8×1020CFU /ml, after high-density microorganisms are released into the biochemical pool, the biomass in the pool quickly increases to more than 2.0×104mg/L, which can completely decompose the pollutants in the sewage into CO2 and H2O, thereby purifying the sewage.
2. This equipment is an ideal sewage biological treatment equipment. It can generate different populations, different bacterial genera, different temperatures, and different sewage treatment needs of microorganisms according to the sewage treatment needs of different types, different properties, and different environments, especially Suitable for urban domestic sewage, rural domestic sewage, medical sewage, industrial wastewater, livestock and poultry breeding wastewater, high-salt wastewater, high ammonia nitrogen wastewater, toxic and harmful wastewater, heavy metal wastewater, landfill leachate and other waste (sewage) water treatment needs.
This equipment can also be directly matched with old sewage treatment projects such as contact oxidation method, AB method, A/O method, oxidation ditch, SBR, etc., without changing the sewage treatment process or civil engineering. , realizing various purposes such as sewage treatment upgrade and expansion, sludge reduction, nitrogen and phosphorus removal, reclaimed water reuse, etc. The equipment can also be used to remove micro-pollution in landscapes, rivers, lakes, rivers, saltwater lakes, bays, land and other fields. Protect the public environment.
3. The microbial generator produces high-density dominant microbial flora, which can quickly eat pollutants and sludge in sewage without producing odor and without sewage. Compared with traditional methods, the energy consumption of mud dehydrators, sludge conveyors, mud cake transport trucks, waste gas treatment equipment and high-power blast aeration equipment is 1/8 of the activated sludge method, and equipment investment can be saved by hundreds of millions. 70/70, it can also operate on shallow pools, thus reducing the volume and depth of the sewage treatment pool, greatly reducing one-time investment costs and long-term management costs.
4. The equipment generates After the high-density microbial flora enters the treatment tank through the jet, it can quickly reduce the biological oxygen demand (BOD), chemical oxygen demand (COD) and suspended solids (TSS) in the sewage, and has strong denitrification and phosphorus removal Function, it can also convert Category 5 water into Category 3 or above in a very short time, eliminate the odor in the sewage within 7 days, eat about 50% of the sludge in the sewage within 10 days, degrade 20% of BOD every day, and within 10-15 days Achieve standard discharge or reclaimed water reuse.
Using this equipment to treat sewage does not worry about sludge expansion, and is not subject to operator education and age restrictions. It is easy to manage, safe and reliable.
5. As the occurrence of high-density microbial flora continues to increase, the biological oxygen demand (BOD) in sewage is becoming less and less. A large number of microorganisms lose their survival energy due to lack of BOD and self-destruct, turning into carbon dioxide and water. Microorganisms that are not self-extinguished can also become food for fish and plankton, thereby forming a benign biological environment.
The state-of-the-art treatment and purification process has no odor, no sludge, no secondary pollution, and creates a green environment.
6. The use of traditional biochemical methods to treat sewage is affected by changes in climate and water temperature. When the temperature changes every If the temperature is lowered by 10 degrees, the enzymatic reaction speed of microorganisms will be reduced by 1-2 times. The climate will lead to insufficient activity of microorganisms, resulting in poor sewage treatment effects. This not only threatens sewage treatment plants in the north, but also poses a serious threat to sewage treatment plants in the south during winter. After the test, the patented product biogenerator produced by Guizhou Great Wall Environmental Protection Technology Co., Ltd. completely solved this problem. After the high-concentration microbial flora produced by the generator is released into the aeration tank, its biomass quickly reaches 2.0×104mg/L The above increases the biological concentration in the aeration tank by 10 times compared with activated sludge, filling the technical problem of insufficient biomass and poor sewage treatment effect due to low water temperature.
7. Use traditional biochemical methods It is used to treat high concentration, high ammonia nitrogen, high salt content, toxic and heavy metal wastewater. Due to the small number of microorganisms in these wastewaters, the quality of the effluent after wastewater treatment is poor, the effect is unstable, and it is difficult to meet the discharge standards. Microbial generators are used to The unique method completely solves this problem. The generator can continuously send the produced high-concentration microbial flora of more than 1.8×1020CFU/ml into the aeration tank, which is more than 10 times higher than other sewage treatments. 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. Nitrates and sulfates become nutrients for the growth of microorganisms, so that the microorganisms It has been further derived that even if it is affected by cold weather, low temperature, shock load, high concentration, high ammonia nitrogen, high salt content, toxicity, and heavy metal inhibition, it cannot stop the vying for the throne and the army of microorganisms that come one after another, forming a negative impact on sewage treatment. A strong lineup can be used to degrade and digest pollutants in sewage, and ultimately achieve discharge of wastewater up to standard or reuse of reclaimed water.
8. Traditional river management is inseparable from treatment processes such as dams, water cutoffs, and dredging. Projects The cost is high, the construction period is long, and the amount of silt is large. The biogenerator is installed directly upstream of micro-pollution sources such as landscapes, rivers, lakes, rivers, saltwater lakes, bays, and land, cutting off and blocking the source of pollution, and degrading pollution and eating through microorganisms.
