Description
Technical field
The utility model relates to a kind of reactor, particularly a kind of reactor that is applicable to the bio anaerobic processing of waste water.
Background technology
Develop rapidly along with industrial, the treatment technology of waste water has caused that people pay close attention to widely.The anaerobic treatment of waste water is a kind of important technology of waste water harmless treatment, and wherein, anaerobic reactor is the key equipment that anaerobic waste water is handled.
At present, the equipment of conventional anaerobic waste water processing comprises UASB anaerobic reactor, anaerobic filter, fluidized-bed reactor etc.Above-mentioned various device exists obvious defects: floor space is big, the volumetric loading instability, and the byproduct operability is little, filtrate stops up easily and is aging, and equipment life is short, and maintenance of equipment simultaneously is more, therefore, need a kind of new anaerobic reactor of design badly, to satisfy the needs of field of waste water treatment.
Summary of the invention
The utility model technical issues that need to address are a kind of internal-circulation anaerobic reactors of design, to overcome the above-mentioned defective that prior art exists.
Reactor of the present utility model comprises:
Housing, one-level triphase separator, secondary triphase separator, water inlet water distributor, one-level upcast, secondary upcast, the gentle liquid trap of downtake;
Said gas-liquid separator is arranged on the top of housing, and its top is provided with the collecting methane mouth;
The gas-liquid separator is inserted on the top of said one-level upcast and secondary upcast, and its port is higher than the bottom of gas-liquid separator;
Said secondary triphase separator is arranged on the top of housing, and its top is connected with the bottom of secondary upcast;
Said one-level triphase separator is arranged on the bottom of secondary triphase separator, the middle part of housing, its top is connected with the bottom of one-level upcast, cavity between one-level triphase separator and the secondary triphase separator is the deep purifying reaction chamber, and the cavity between the bottom of one-level triphase separator and housing is the expanded bed reaction chamber;
Said water inlet water distributor is arranged on the bottom of housing, and water-in is arranged on the bottom of housing, and is connected with the water inlet water distributor, and water outlet is arranged on the top of housing.
Said downtake passes secondary triphase separator, one-level triphase separator and water inlet water distributor successively, the bottom of through housing, and its upper port is connected with the gas-liquid separator.
Reactor of the present utility model is operation like this:
The waste water that needs to handle pumps into reactor through the water inlet water distributor, evenly mixed with circulating sludge and water outlet, enter the expanded bed reaction chamber, the most COD generation biogas that is degraded is collected and is separated by the one-level triphase separator, gas rises, when gas rises, promote water and mud and move upward, reach the gas-liquid separator that is positioned at reactor head through the one-level upcast, biogas separates from water and mud, leaves reactor by the collecting methane mouth;
Water and mud are mixed directly to be slipped to reactor bottom through downtake, formation internal recycling stream, handled once more in the deep purifying reaction chamber from the water outlet of first step disengaging zone, the biogas that produces is collected by the secondary triphase separator, and the anaerobism water outlet enters follow-up workshop section through leave the reactor gravity flow by water outlet.
In the expanded bed reaction chamber, because what water inlet made progress flows, the disturbance that internal recycle effect and gas produce, mud is the expansion suspended state in the expanded bed reaction chamber, waste water contacts fully effectively with microorganism (mud), mud produces higher activity, higher organic loading rate and transformation efficiency is provided, compare test shows, in reactor of the present utility model, the methanogenesis activity of granule sludge is higher than 2 times of UASB reactor, and high reactivity blended microorganism makes reactor of the present utility model have the ability of handling high-concentration waste water in this district.
In the deep purifying reaction chamber, because lower sludge loading has produced effectively the lag phase of processing and microorganism again, almost removed degradable COD, because in the former expanded bed district, gas is collected by first separator.The COD hexyl of having degraded originally is degraded, and therefore the disturbance that produces owing to gas in post processing zone is very little, and surperficial upflow velocity also reduces relatively, because internal recycle stream does not pass through this zone of reactor.Under same microorganism growth condition, compare with the UASB reaction conditions, although integral reactor load height, because the still optimistic microorganism delay of generation in this district of above-mentioned two factors.The sludge concentration of second reaction zone is very low, and the space of sludge bulking is bigger, and this has just been avoided the sludge loss when peak load impacts.
In inner circulation reactor of the present utility model, the COD in the waste water is through anaerobic treatment, and the COD in the reactor in the anaerobic grain sludge degradation water is converted into biogas, in the biogas with methane and CO
2Be main, the hydrogen sulfide that also has trace, therefore, internal recycle is based on the gas lift principle, not different (not the needing water pump) that produce owing to contained gas volume in " rising " and " decline " pipe at this, be subjected to the driving of reactor air-flow, the cycling stream ratio depends on into water COD concentration, therefore can reach voluntarily and regulate.The high high gas flow of water inlet COD load aerogenesis just has more circulation, and it is diluted just to have stronger water inlet.
Because the gas-powered air-flow of collecting in the fs rises, and forms internal recycling stream, so be named as inner circulation reactor for this reactor.
Because the internal recycle The Application of Technology, its treatment effect is compared with traditional anaerobic reactor, and following advantage is arranged: processing organic pollutant load is 5 to 10 times of traditional anaerobic reactor; Floor space is sixth to four/one of traditional anaerobic reactor; Anti-shock loading is strong, and the operation treatment effect is stable; Working cost is low; Reactor is totally-enclosed system, the free from extraneous odour discharging; Start soon, the construction period is short.
