Welcome to inquire! Contact: Chang Chih-feng. Sewage treatment nitrification and denitrification process factors: biological nitrogen removal in wastewater treatment chemical wastewater treatment methods, denitrifying bacteria, denitrifying bacteria play an important role in the biodegradation process for these bacteria have certain environmental conditions: 1) DO: hypoxia structures sewage treatment, the best DO denitrification of 0.5mg / L or less, in the aerobic structures in aerobic metabolism of organic matter, nitrification bacteria will NH4 + -N oxidized NHx - N, all need oxygen, DO should be controlled at 2mg / L or more. DO change wastewater treatment approach that can significantly affect the system, and the indicative amount of denitrifying bacteria changes in the number of microorganisms. When a mixture of low DO concentrations, indicative of microbial nitrification process of a small number of pharmaceutical wastewater treatment methods, nitrification nitrogen poor; on the contrary, it is indicative of the number of microorganisms and more ways to nickel-containing wastewater treatment, nitrification rate of nitrogen also varies the increase. However, due to the high concentration of dissolved oxygen on nitrification bacteria have a certain extent, so DO control in general greater than 2mg / L conditions of low appropriate. Above picture is for reference only, please consult our detailed models, more models, please visit our official website or call us for the design life of sewage treatment equipment: 1, sewage treatment equipment and materials selection and design, supply should have a long life Features, 24 hours a day to adapt to the long-term continuous operation, and the minimum amount of maintenance. Seller shall use similar components or extensive record of inspection records demonstrate that all components have switched to meet these requirements. 2, routine maintenance and repair work of sewage treatment equipment should be as simple as possible, without senior skilled personnel to operate. 3, sewage treatment equipment and efficient sedimentation tank failures accumulated no less than 10000h. 4, except such as fillers, fuses and other parts need frequent replacement of wear and tear, the sewage treatment equipment to withstand the wear of all parts, from the new life of continuous use to normal operation when you need to replace or repair, or a total of not less than life specified period of time. Sewage treatment equipment all the gears and bearings should have a design life of 100,000 hours, and the calibration of the load should be at least 125% of the workload.
