Description

Three-phase fluidized-bed reactor
Technical field
The present invention relates to environmental protection and biochemical reaction equipment technical field, particularly a kind of three-phase fluidized-bed reactor that is used for sanitary sewage and Industrial Wastewater Treatment.
Background technology
Bioremediation has been the main stream approach of current sewage disposal, and this mainly is that operating cost is low, and is easy and simple to handle because the bioanalysis capital expenditure is economized.Microorganism by assimilation and dissimilation degradation of contaminant and realize self propagation, is removed the removal that can realize organic matter, nitrogen, phosphorus and other pollutants behind the organic matter in the sewage by Separation of Solid and Liquid in reactor.Three-phase fluid bed reactor is one of biochemical reactor the most commonly used.Compare with traditional handicraft, the three-phase fluid bed reactor treatment effeciency is higher, and operating cost is lower, and effluent quality is better.
Internal-circulation type three-phase fluidization bed process is apposition growth biology or treatment based on immobilized microorganisms technology, and the carrier that is added suspends in water and constantly flow to form the fluidisation attitude with current.The characteristic feature of inside circulation triphase fluidized bed technology is to adopt inside and outside double-barrel structure, realizes the mixing of gas, water, carrier and forms circulating fluidized by the lifting of air at inner core.But in traditional fluid bed, promote speed and descend and backflow phenomenon occurs, and gas, water mixes and also have certain short stream, channeling, cause actual effective reacting volume to reduce owing to the effect of gravity and resistance to water-flow can produce.In the recent period this problem has obtained preliminary solution, promptly establish in the three-phase fluid bed reactor bottom reducing mouth mix to strengthen gas, water (Cao Wenping. novel reducing type three phase fluidized bed, application for a patent for invention number: 200620134874.7, publication number: CN200977457Y).But this kind reactor bottom is a cone, during practical engineering application constructional difficulties and also be not easy to the maintenance.
Compare with general bioreactor, inside circulation triphase fluidized bed reactor has very high biomass, can be up to 10g/L~20g/L, and good mixing effect, the mass-transfer efficiency of oxygen and utilization rate are also higher, so its hydraulic detention time is shorter, takes up an area of and lack reduced investment.But too high microbial biomass has aggravated the difficulty of Separation of Solid and Liquid, and it is up to standard to cause delivery turbidity to be difficult to.Filtering type highly effective separation and inside circulation triphase fluidized bed reactor (Jia Limin. filtering type highly effective separation and inside circulation triphase fluidized bed reactor, application for a patent for invention number: 200510012015.0, publication number: appearance CN 1721342A) makes this problem obtain preliminary solution.But the suspension major part of water outlet is still at 15mg/L~20mg/L, and waste water recycling is the inevitable requirement of " recycling economy promotion law ", and this technology can not satisfy objective demand fully.In addition, because microorganism concn is higher in the reactor, filtering layer stops up easily, needs frequent backwash, brings many difficulties to practical operation.
Summary of the invention
The technical problem that the present invention mainly solves is: inside circulation triphase fluidized bed consersion unit air water mixed effect is poor, the equipment operating difficulties, and solid-liquid separation effect is poor, and treatment effect is undesirable, the delivery turbidity height.For addressing this problem, technical scheme of the present invention is: a kind of three-phase fluidized-bed reactor, and it comprises air water mixed zone, reaction zone, Disengagement zone, filtering area; The air water mixed zone places this equipment foot, and its side bottom is provided with water inlet and air inlet; Reaction zone is by urceolus and inner core (9 1) constitute; The air water mixed zone is connected with reaction zone by the micropore air distribution plate; The Disengagement zone is positioned at the top of this equipment, is provided with annular settling zone and filtering area outside the Disengagement zone, and both are connected by perforated plate; Filtering area middle part is provided with filter assemblies, filter assemblies with by water pump, valve (17 1), valve (17 2), valve (17 3), valve (17 4), flowmeter (16 1), flowmeter (16 2) be connected with backwashing system with the water outlet of clear water reserviors composition, it is characterized in that the air water mixed zone is a cylindricality, the filter assemblies that the filtering area middle part is provided with is a membrane module.
The outer wall of air water mixed zone is connected by the consersion unit housing with urceolus, forms the deformation gauge structure between air water mixed zone and the reaction zone, i.e. side-looking is a trapezium structure wide at the top and narrow at the bottom.The air water mixed zone is a cylindricality, and its ratio of height to diameter is 1: 1~2: 1, air water mixed zone and inner core (9 1) the area ratio is 1: 1~1: 5.
The reaction zone middle part is provided with urceolus and inner core (9 1) double-barrel structure that constitutes, inner/outer tube area ratio is 1: 1.5~1: 5, urceolus and inner core (9 1) ratio of height to diameter of reaction zone of the double-barrel structure that constitutes is 6~12, inner core (9 1) bottom be horn mouth.
The consersion unit top is provided with Disengagement zone, settling zone and filtering area, and the Disengagement zone is connected by the ring-type perforated plate with the settling zone, but but settling zone bottom is provided with the spoil disposal (water) mouthful of not only spoil disposal but also draining.The top, settling zone is a filtering area, and the filtering area middle part is provided with filter assemblies, and this filter assemblies adopts ceramic membrane or hollow-fibre membrane.
Beneficial effect of the present invention is:
1, air water good mixing effect, easy construction and also be easy to the maintenance
Because the three-phase fluidized-bed reactor bottom is provided with air water mixed zone, the employing micropore air distribution plate gas distribution of cylindricality, air, waste water are after mix rapidly air water mixed zone limited below the perforated plate, form very big air water pressure, drive filler or immobilized microorganism and promote rapidly, make that promoting power strengthens with mode of jet.Can effectively improve the air water mixing efficiency, avoid the air water mixed zone to produce the dead band, effectively improve the utilization ratio of oxygen.The air water mixed zone of cylindricality is adopted in consersion unit bottom, easy construction and be easy to maintenance during practical engineering application.
2, good effect of separating solid from liquid, effluent quality is good
Since three-phase fluidized-bed reactor make full use of inside circulation triphase fluidized bed consersion unit to the pollutant highly-efficient treatment in, the coupled film filtering technique carries out Separation of Solid and Liquid efficiently to the consersion unit water outlet, good effect of separating solid from liquid, delivery turbidity is low, can hold back microorganism, prevent the microorganism loss, further improve microorganism concn in the consersion unit, the enhancement microbiological treatment effect.Because reaction medium carries out membrane filtration to filtering area after Disengagement zone, twice separation in settling zone in the consersion unit, can effectively alleviate film pollutes, reduce energy consumption, reduce the backwash frequency, reduce operating cost, effluent quality is good, can reach urban sewage reutilization city miscellaneous water water standard (GB T18920-2002).
