Principle of work:
the utility model adopts the outer circulation of microkinetic waterpower, i.e. EGSB water outlet is to going out bucket, and the water pump through low lift and large flow rate is back to reactor drum again; Regulate the internal reflux amount through by-pass valve control; Come the surface load in the controlling reactor, and then the hydraulics of controlling reactor realizes outer circulation, this method power consumption is very little; Be traditional about 10% ~ 30%, power consumption descends 70 ~ 90%.This method is a microkinetic waterpower outer circulation type.
the utility model adopts unpowered gas to carry internal recycle; Be that the biogas that produces in the reactor drum is collected through triphase separator; The biogas-lift mixed solution is to separating bag, and after methane recovery was utilized, mixed solution was back to the bottom of reactor drum through the muddy water downtake.The biogas that this method produces with self does not need extraneous mechanical power promptly can realize internal recycle as promoting power, makes granule sludge be in swelling state in the biogas production process in the reactor drum.
the utility model EGSB reactor drum adopts unpowered gas to put forward internal recycle and microkinetic waterpower outer circulation technology, for normal temperature and underload organic waste water, can increase the hydraulic load of reactor drum, guarantees treatment effect.For ultrahigh concentration or contain the waste water of Toxic matter, can dilute the substrate concn and the toxic substance concentration that get in the reactor drum, reduce its inhibition and murder by poisoning to mikrobe.The floc sludge that helps simultaneously in the reactor drum transforms to granule sludge, and small-particle mud transforms to macrobead mud.
the utility model EGSB reactor drum adopts unpowered gas to put forward internal recycle and the outer circulation of microkinetic waterpower technology, unpowered gas carry internal recycle promptly with the biogas that self produces as promoting power, realize the internal recycle of mixed solution.Gas stripping inner circulation reactor is formed by stacking the first anaerobic reaction chamber and the second anaerobic reaction chamber, and a gas-solid-liquid triphase separator is respectively established at the top of each anaerobic reaction chamber, as the overlapping series connection up and down of two UASB reactor drums.Microkinetic waterpower outer circulation technology is promptly realized by the water pump pressurization, must consume a part of power; Reflux ratio generally is controlled between 100%～300%.The external reflux inlet point should be arranged on out on the bucket, in reactor drum, carries out water distribution with former water; Effluent recycling can adopt the backflow of directly pressurizeing of low lift in-line pump.
the utility model main purpose is the liquid upflow velocity that improves in the reactor drum; The granule sludge bed is fully expanded, fully contact between sewage and the mikrobe, strengthen mass transfer effect; Can also avoid the generation EGSB reactor drum of interior dead angle of reactor drum and short stream to pass through effluent recycling; Make its ability, toxicant concentration in the water into is diluted to mikrobe is no longer had toxic action, can improve mixing of waste water and mud simultaneously with anti-shock loading.So the EGSB reactor drum can be handled the high concentrated organic wastewater that contains toxicant.To containing the waste water of high density fat or lipoid, can improve mixed effect through going out water cycle.During initial start-up, go out water cycle and make into water CODCr concentration dilution to 5g/L, this is to starting and formation of granule sludge is extremely favourable.
Working process:
waste water will be intake through water distributor and will be assigned to the bottom of whole reactor equably, and produce a uniform upflow velocity.Compare with the UASB reactor drum, the EGSB reactor drum is because aspect ratio is big, and its needed water distribution area can be less, adopted water cycle simultaneously, and the flow velocity in its water distribution aperture is big, guarantees even water distribution more easily.Following triphase separator and last triphase separator are divided into upper and lower two zones with entire reaction, and the bottom is the sludge bulking bed, and top is the precision processing district.When waste water passed through the granule sludge layer of anaerobic reactor bottom, most organism was degraded, and produces a large amount of biogas simultaneously; Process is the precision processing district on the waste water continuation entering top of triphase separator down, and the residual organic substances in the waste water can further be degraded by the anaerobic grain sludge on top, and the biogas of generation is by upper strata triphase separator separated and collected.Higher upflow velocity can make that mud is able to sufficient the contact with waste water in the reactor drum; And cause the expansion of granule sludge at the sludge bulking bed, and so just can guarantee the thorough mixing of mud and sewage, reduce the dead angle in the reactor drum; Waste water fully contacts with granule sludge; Strengthened mass transfer effect, produced a large amount of biogas, biogas, mud and waste water are separating in the triphase separator down; It mainly acts on is that water outlet, biogas, mud three-phase are effectively separated, and mud is effectively held in reactor drum stayed.Biogas gets into the mud-water separation bag because of having saturation water and not separating muddy water fully through the biogas upcast, and the three is eddy flow in the mud-water separation bag, and muddy water is back to the bottom of reactor drum through the biogas downtake, and isolating biogas is recycled through the methane recovery pipe.
triangle effluent trough is arranged on the top of EGSB reactor drum, guarantees the waste water after the collection and treatment equably as far as possible, and certain distance is established V-notch weir at interval in horizontal catchment tray.Even for guaranteeing water outlet, the utility model EGSB reactor drum adopts the multi-channel water-out manners, and each groove both sides is provided with V-notch weir, the adjustability of considered V-notch weir height during design, and weir head is not less than 25mm.
are because the reactor drum upflow velocity is higher; In operational process, having a large amount of anaerobic grain sludges runs off; Therefore at the water outlet bucket device granule sludge withdrawer of reactor drum; Can effectively utilize the mode of backflow to carry out the mud recovery, be left to the muddy water downtake, be back to the bottom of reactor drum through the granule sludge return tube.To the subsequent disposal facility, in reflux pump, the water pump through low lift and large flow rate is back to reactor drum to a part of waste water to a waste water part after treatment again through the pump water inlet pipe through rising pipe; Regulate the internal reflux amount through unit; Gets into reaction zone through swirler-and come the surface load in the controlling reactor, and then the hydraulics of controlling reactor realizes outer circulation that this method power consumption is very little; Be traditional about 10% ~ 30%, power consumption descends 70 ~ 90%.
The advantage that the utlity model has the EGSB reactor drum of gas stripping type internal recycle and the outer circulation of microkinetic waterpower is:
The two-stage triphase separator has been adopted in
1. the utility model; Be divided into the high load region of bottom and the low load region on top through structure formation; Organic loading and hydraulic load in two zones are all inequality, have guaranteed effective delay of granule sludge; Higher upflow velocity and backflow have promoted fully contacting of sewage and mud, have created condition for keeping sludge activity; The internal reflux amount confirms to have self-regulation according to the gas production rate (water inlet CODCr concentration) of lower floor's triphase separator, can save energy consumption.
2. the utility model EGSB reactor drum adopts unpowered gas to put forward internal recycle and the outer circulation of microkinetic waterpower technology. and this method power consumption is very little, is traditional about 10% ~ 30%, and power consumption descends 70 ~ 90%
