Wastewater treatment system using high efficiency upflow anaerobic sludge bed reactor

摘要

The present invention relates to a wastewater treatment system using a high-efficiency upflow anaerobic sludge-phase reactor, and more particularly, to an anaerobic wastewater treatment method using a self-immobilizing microorganism, which utilizes physiological characteristics of mutually coexisting microorganisms contributing to the anaerobic methane fermentation reaction, This system is designed to treat mainly carbohydrate and protein industrial wastewater. The wastewater treatment system treats the wastewater as a condensate of highly active anaerobic microorganisms, that is, treated by granular sludge. The wastewater treatment system relates to a two-stage anaerobic wastewater treatment system using granular sludge produced under phase-separated conditions depending on the relative hydrogen partial pressure.;1 shows a structure of a high efficiency upflow anaerobic sludge wastewater treatment system in which a storage tank 1 for collecting wastewater, an alkali supply tank 2 and a micronutrient supply tank 4 are connected to a pump 5 and a flow rate regulator 5 5b to the first-stage reaction tank A and the pore-propagation tank 3 to the second-stage feed tank B through the pump and the flow rate regulator 5c, The gas inflow port is connected to the gas desulfurization device 18 and the gas storage tank 19 and the primary gas is introduced into the gas desulfurization device 18 and the gas storage tank 19, The water outlet 10 was connected to the first outlet reservoir 11 and the second reservoir was connected to the second reservoir B. The gas inflow port 9 is connected to the gas desulfurizer 18 and the gas reservoir tank 19 at the upper portion thereof. The inflow water distributing device 6, the partition 13, To form a second treated water outlet (17). The sludge conveying port 16 is connected to the first stage reaction tank A and the second stage reaction tank B and is connected to the sludge layer of the first stage reaction tank and the excess granular sludge storage tank 20, Clinical sludge generated in the reaction tank can be reused. In the second-stage reaction tank, not only the wastewater treatment but also the self-decomposition process of the sludge occurs, so there is no sludge to be finally disposed, and the burden on the sludge treatment can be greatly reduced. Therefore, the wastewater treatment method according to the present invention has an effect of improving the stability and economical efficiency in the treatment of industrial wastewater.
