Background technology
Anaerobic baffled reactor (ABR-AnaerobicBaffledReactor) is to arrange a series of deflection plate along water (flow) direction in the reactor, reactor is separated into the reative cell of several series connection, and each reative cell can be seen as a relatively independent up-flow sludge bed system.Waste water enters the upper and lower baffling of reactor tailing edge deflector and advances, and passes sequentially through the Sludge Bed of each reative cell, and the organic substrate in waste water is by each reative cell and is fully contacted with microorganism therein and is removed.ABR be last century early eighties developed by MeCarty and the partner thereof of Stanford university of the U.S..ABR is referred to as third generation anaerobic reactor, and not only biosolids interception capacity is strong for it, and waterpower mixing condition is good.
The startup of anaerobic reactor is often referred to newly-built system with mud (such as Sewage Plant anaerobic sludge, the digested sludge of the digester) inoculation without domestication, makes reactor reach design load and the process of organic matter removal efficiency.Owing to the generation cycle of anaerobe is long, growth rate is low, and therefore the start-up course of anaerobic reactor is long.Starting the difference of factor according to anaerobic reactor, be generally 30 ~ 100d, this seriously governs its extensive use in industrial wastewater and domestic sewage processing system.Properly functioning anaerobic baffled reactor is dependent on ascending current and ripe anaerobic sludge output bubble, makes sludge suspension promote in room upper.Sludge quantity in reactor is made to reach certain numerical value the properly functioning process waste water of ripe ability, so the startup of ABR just becomes very crucial.Anaerobic baffled reactor is commonly used for process and is difficult to biodegradable industrial wastewater, and the domestication start-up course time of reactor also can extend than processing sanitary sewage.Additionally bioreactor is in properly functioning process, once production development accident, microorganism fungus kind mortality, cause that bioreactor system collapses, so needing bioreactor to be again started up, anaerobe needs again to cultivate and domestication, needs again to wait a very long start-up course.
Affect the factor that anaerobic reactor starts a lot, including the factors such as physical dimension of the composition of pending waste water and concentration, the quantity of seed sludge and activity, environmental condition (pH value, temperature etc.), the supplementing of trace element, operating condition (COD volumetric loading, hydraulic detention time etc.) and reactor.
In recent years, follow-on ABR reactor generally all can arrange hanging filler or add floating stuffing.To add floating stuffing, the position of the mobile bed that floating stuffing is formed is generally uncontrolled.At the ABR reactor start-up initial stage, seed sludge is owing to being subject to action of gravity, it is easy to be gathered in the bottom of reactor.Floating stuffing is gathered in the top of upward flow lattice room, and seed sludge is then gathered in the bottom of upward flow lattice room, thus floating stuffing is little with the contact portion of seed sludge.If the filler proportion added is relatively big, close to 1 or more than 1, in the reactor start-up later stage, biofilm development on filler obtains comparative maturity, then filler is readily collected in the bottom of reactor upward flow lattice room, and relatively, the mud on the top of upward flow lattice room and biomembrane distribution are just seldom.In general ABR reactor, the position of filler is uncontrolled, thus filler is also uncontrolled with contacting of seed sludge.
The present invention intends making improvements in the facility structure to anaerobic baffled reactor and startup operating condition, improves the controllability of filler in ABR reactor, to shortening the startup time of reactor.
