Description
Technical field
Patent of the present invention is related to technical field for the treatment of of organic waste, and particularly a kind of high efficiency anaerobic reactor processes organic waste
The technique of water.
Background technology
With the reach of science, the deepening continuously of scientific research, many new technologies, new material, new concept is widely used in ring
Industry is protected in border, makes the significant progress that China environmental protection technology obtains.Food, brewage, pharmacy, the discharge of the industry such as chemical industry big
Effluent part broadly falls into high concentrated organic wastewater, reaches processing intent using conventional materialization, biochemical treatment difficulty, there is behaviour simultaneously
Manage, investment is big, operating cost is high to wait a system problem.
High concentrated organic wastewater is processed using anaerobic process, its superiority progressively obtains recognizing and paying attention to, in recent years of people
Anaerobic technology is developed quickly, and in UASB anaerobic treatment process equipment, upward flow anaerobic sludge comes with its simple structure, process
Efficiency high, effect are good, applied widely, floor space is little, processing cost is low, reduced investment and adopted in a large number.
First generation anaerobic reactor with anaerobic digester as representative, due to cannot be to hydraulic detention time and sludge retention
Temporal separation, causes to process the time of staying at least 20-30d of waste water, therefore treatment effeciency is extremely low.
In the 60-70 age in 20th century, occur in that second generation anaerobic reactor with UASB as representative it is achieved that during hydraulic retention
Between and sludge retention time separation.Thus improve the concentration of mud in reactor.The top setting gas of UASB reactor,
Solid, liquid three phase separator, bottom is sludge suspension floor area and Sludge Bed area, and waste water uniformly pumps into Sludge Bed by reactor bottom
Area, is fully contacted reaction with anaerobic sludge, and organic matter is resolved into biogas by anaerobe.Liquid, gas and solid form mixed
Close liquor stream and rise to three phase separator, so that three is separated well, make more than 80 organic matter be converted into biogas, complete to give up
Water treatment procedure.The formation that its advantage is mainly reflected in granule sludge makes the sludge concentration in reactor increase substantially, waterpower
The time of staying therefore greatly shortens, thus improving operational efficiency.
Efficient anaerobic reactor, in addition to ensureing hydraulic detention time and sludge retention time, also will ensure that both are abundant
Mixing, but simple mixing occurs the present of sludge loss.Therefore, the nineties in 20th century, have developed with EGSB as representative
Third generation anaerobic reactor.Its construction with UASB reactor have similarity, can be divided into into water water distribution system, reaction zone,
Three-phase separation area and outlet canal system.It is a difference in that with UASB reactor, EGSB reactor is provided with special effluent recycling system

The height answering device is up to 15～20 meters.The expanded bed of granule sludge improves the contact between useless Organic substance in water and microorganism,
Enhance mass transfer effect, improve the biochemical reaction speed of reactor, thus substantially increasing the treatment efficiency of reactor.But
It is that the water at anaerobic reactor top flows to bottom, is uniformly flowed back by water distributor, flow velocity is too high, mud is easy to run off, operational effect is not
Stable.
