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, outstanding economic benefits
The micro-device produces a high density of advantageous microbial flora, can quickly eat off the pollutants and sludge in the sewage, and does not produce a foul odor, without sludge dewatering machine, sludge transfer machine, mud cake outgoing car, exhaust gas treatment equipment and high-power blower aeration equipment, and the traditional method of comparing the energy consumption of the activated sludge method is 1/8, the investment in equipment can save Seventy percent, but also in the shallow pool on the operation, so that the sewage treatment tank volume is reduced, the depth of shallow, greatly reducing the cost of a one-time investment and long-term management costs.
4, easy to manage, safe and reliable
The equipment produces a high density of microbial flora through the jet stream into the treatment pool, can quickly reduce the biological oxygen consumption in sewage (BOD), chemical oxygen demand (COD) and solid suspended solids (TSS), and has a very strong function of denitrification and phosphorus removal, but also in a very short period of time so that the 5 types of water into more than 3 types, within 7 days to eliminate the The odor in the sewage, eat up about 50% of the sludge in the sewage in 10 days, degrade 20% of the BOD every day, and achieve the standard discharge or water reuse in 10-15 days.
The use of this equipment to treat sewage without the worry of sludge expansion, but also not subject to the age limit of the operator's education, easy to manage, safe and reliable.
5, no secondary pollution, creating a green environment
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-extinguishing into carbon dioxide and water, the micro-organisms not self-extinguishing can also become the bait of the fish and zooplankton, and thus the formation of a virtuous ecological Processing purification process, no odor, no sludge, no secondary pollution, creating a green environment.
6, not affected by climate, complete biochemical treatment
The use of traditional biochemical method of sewage treatment, affected by the climate and water temperature changes, when the temperature is reduced by 10 degrees per microbial enzyme 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 plants, for the south in winter is also a severe test of the sewage treatment plant Treatment plant is also a severe Jun test, Guizhou Great Wall Environmental Protection Science and Technology Co., Ltd. production of patented products microbial purification and treatment equipment completely solved this problem, the generator system produces a high concentration of microbial flora released into the microbial purification and treatment system, its biomass interrogation rate of more than 2.0 × 104mg/L, so that the microbial purification and treatment equipment in the biological concentration of activated sludge compared to improve 10 times.
