Problems solved by technology
However, if the upflow speed is too fast, it will easily cause sludge loss, and there will be mud running when the water is discharged.
[0004] Existing high-efficiency anaerobic reactors generally need to reflow the effluent of the reactor, but when treating some types of high-concentration organic wastewater, "struvite" will crystallize due to the reflow of effluent, which will block the reflux and water distribution system, making the treatment device unable to run

The invention relates to an efficient anaerobic biological tower reactor which comprises a tank body, a water circulation part, a reaction part and a three-phase separator, wherein the reaction part and the water circulation part are arranged in the tank body; the reaction part is provided with the three-phase separator; and the bottom of the tank body is provided with a rotary water distributionpart. the adopted large-resistance rotary water distribution manner which has the functions of even water distributing and stirring runs stably and is simple to operate, fictional water loss of waterinflow is far smaller than local water loss, the service areas of all water outlets are identical basically so that water distribution is even without dead zones, water inflow amounts per unit area are basically identical, the water inflow and sludge can fully contact, anaerobic sludge is in an expansion state in the vertical direction, anaerobic microorganism and base material fully contact and good transfer effect is achieved. Through arranging different installation angles of water discharge tubes, rotary distribution is achieved so that the anaerobic sludge rotates in the horizontal direction so as to further avoid the occurrence of head zones; the problem of struvite crystalline blockage caused by effluent backflow is avoided; and organic pollutants are efficiently removed, energy consumption is low, gas production rate is high, thereby being beneficial to energy recovery.
Description
technical field [0001] The invention belongs to the technical field of waste water treatment, and relates to a high-efficiency anaerobic biological tower reactor for treating medium and high concentration organic waste water. Background technique [0002] The treatment of organic wastewater is an extremely important part of environmental protection. Among them, medium and high concentration organic wastewater has become an important aspect of wastewater treatment due to its large pollution load. Anaerobic biological treatment is a process in which organic matter in wastewater is converted into biogas under the action of methanogens, and at the same time organic pollutants in wastewater are removed. [0003] At present, high-efficiency anaerobic biological treatment technologies mainly include upflow anaerobic sludge bed reactor (UASB) and expanded granular sludge bed (EGSB). Upflow Anaerobic Sludge Bed Reactor (UASB) is the first generation of anaerobic reactor. Suspended s...
