2, microbial generator
Microbial generator is mainly based on biological purification and hydrodynamic principles, the use of microorganisms in the process of life activities in the wastewater soluble organic matter and part of the insoluble organic matter effectively removed, advanced technology, stable performance, safe to use, especially suitable for a variety of wastewater treatment and micro-pollution treatment has the following advantages:
(1), the equipment adopts three-stage occurrence, alternate operation, level by level derivatives, logarithmic growth technology, resulting in the generator to produce microbial density up to 1.8 × 1020CFU/ml, high-density microorganisms released into the biochemical pool, the pool biomass rapidly increased to 2.0 × 104mg/L or more, can be sewage pollutants in the complete decomposition of CO2 and H2O, thus making the wastewater It can completely decompose the pollutants in the sewage into CO2 and H2O, thus purifying the sewage.
(2), the equipment for the more ideal biological treatment of sewage equipment, according to different types, different nature, different environmental needs of sewage treatment, generation of different populations, different genera, different temperatures, different sewage treatment needs of microorganisms, especially suitable for urban sewage, rural sewage, medical sewage, industrial wastewater, livestock and poultry wastewater, high-salt wastewater, high ammonia wastewater, toxic and harmful wastewater, heavy metal wastewater, garbage leachate and other wastewater (sewage) treatment needs.
The equipment can also be directly with the contact oxidation method, AB method, A/O method, oxidation ditch, SBR and other old wastewater treatment works, in neither change the wastewater treatment process, nor change the conditions of civil engineering, to achieve the upgrading and expansion of wastewater treatment, sludge reduction, denitrification and removal of phosphorus, water reuse and other purposes. The equipment can also be used in landscape, river, lake, river, saltwater lake, bay, land and other fields to remove micro-pollution and protect the public **** environment.
(3), the microbial generator produces a high density of advantageous microbial flora, can quickly eat off the pollutants and sludge in the sewage, and does not produce odor, without sludge dewatering machine, sludge conveyor, mud cake outgoing car, exhaust gas treatment equipment and high-power air blower aeration equipment, compared with the traditional method, the energy consumption of the activated sludge method of 1/8, the investment in equipment can be saved by seventy percent, can also be It can also be operated on the shallow pool, thus making the sewage treatment tank smaller in size and shallower in depth, and greatly reducing the one-time investment cost and long-term management cost.
(4), the equipment produces a high density of microbial flora through the jet stream into the treatment pool, can quickly reduce biological oxygen consumption in sewage (BOD), chemical oxygen demand (COD) and suspended solids (TSS), and has a strong function of denitrogenation and removal of phosphorus, but also in a very short period of time to make the 5 types of water into more than 3 types of water, 7 days to eliminate the odor of sewage, within 10 days eaten! About 50% of the sludge in the sewage, 20% of the BOD degradation per day, 10-15 days to achieve discharge or water reuse.
Using this equipment to treat sewage without the worry of sludge expansion, but also not subject to the age limitations of the operator's education, easy to manage, safe and reliable.
(5), with the increasing incidence of high-density microbial flora, biological oxygen demand (BOD) in the sewage is also less and less, a large number of microorganisms due to the lack of BOD and the loss of energy to survive self-extinction into carbon dioxide and water, not self-extinguishing microorganisms can also become the bait for fish and plankton, which will form a benign ecological process of treatment and purification, there is no odor, does not produce sludge, no secondary pollution, to create a green environment. No odor, no sludge, no secondary pollution, creating a green environment.
(6), the use of traditional biochemical method of sewage treatment, affected by climate and water temperature changes, when the temperature decreases every 10 degrees, the microbial enzymatic reaction rate is reduced by 1-2 times, the climate leads to microbial activity is insufficient, resulting in poor sewage treatment, not only threatened by the northern sewage treatment plant, for the southern winter sewage treatment plant is also a severe Jun test, Guizhou Great Wall Environmental Protection Technology Co. Ltd. production of patented products biological generator completely solve this problem, the generator produces a high concentration of microbial flora released into the aeration pool, the biomass signaling rate of 2.0 × 104mg / L or more, so that the biological concentration in the aeration pool than the activated sludge to increase by 10 times, to fill the water temperature due to the low biomass caused by low water temperatures, the sewage treatment effect of the poor technical problems.
(7) The traditional biochemical treatment of high concentration, high ammonia nitrogen, high salt, toxic, heavy metal wastewater, due to the microorganisms in these wastewater is less viable, the number of small, resulting in poor quality of effluent after sewage treatment, the effect is unstable, and difficult to meet the discharge standards. Microbial generator in a unique way to completely solve this problem, the generator can produce 1.8 × 1020CFU / ml above the high concentration of microbial flora constantly sent to the aeration tank, compared with other sewage treatment to improve the biomass of more than 10 times, the powerful microbial flora to accelerate the degradation of sewage pollutants in the degradation and digestion, while aeration and oxygen supply significantly accelerates the pollutants are broken down into CO2 and H2O, nitrate, sulfate become nutrients for microbial growth, so that the microorganisms and further derivation, even by the cold, low temperature, shock load, and high concentration, high ammonia nitrogen, high salt, toxicity, heavy metal inhibition, but also can not stop the group of microorganisms competing for the front and back of the microorganisms, the formation of a strong lineup of wastewater treatment, and then the degradation and digestion of wastewater pollutants, and eventually Realize wastewater discharge or water reuse.
(8), the traditional river management can not be separated from the gate and dam, water breaks, dredging and other treatment processes, the project is costly, long construction period, the amount of silt. Biological generator installed directly in the landscape, rivers, lakes, rivers, saltwater lakes, bays, land and other sources of micro-pollution upstream, cut off and block the source of pollution from the source, and through the role of microbial degradation of pollution, eating sludge, removal of odor, phosphorus denitrification, etc. to achieve a thorough
Third, non-powered integrated wastewater treatment equipment
Wastewater treatment for a long time by using aeration tanks, aerators, and Construction of separate sedimentation tanks, filtration tanks, disinfection tanks, as well as chlorine dioxide generator and other traditional processes, engineering investment, covers a wide area, energy consumption, operation and management costs are high, coupled with the need for hydrochloric acid and sodium chlorate reaction to produce chlorine dichloride, and hydrochloric acid is the public security organs of the strict control of hazardous materials, procurement and use of extremely inconvenient.
Chongqing Chutian Environmental Protection Engineering Co., Ltd. developed a non-powered sewage treatment equipment fundamentally revolutionized the traditional process for hospital sewage treatment provides the ideal equipment.
