Abstract
The utility model relates to a UASB (Upflow Anaerobic Sludge Blanket) reactor. A reactor main body has a steel mixing structure, a three-phase separator arranged in the reactor consist of a steel structure baffle plate and a civil engineering structure baffle plate, the steel structure connecting piece in the three-phase separator can be used as few as possible, so that the three-phase separator can run more stably, and simultaneously, the investment cost can be lowered.
Description
Technical field
The utility model relates to sewage treatment area, particularly a kind of UASB reactor drum.
Background technology
In various anerobic sowage bioremediations; The technology maturity of upflow anaerobic sludge blanket process technology is higher; Have simple in structurely, working cost is low, plurality of advantages such as processing efficiency height; And receive the attention of industry day by day, be widely used in the processing of the high and low concentration organic waste water of industries such as food, chemical industry, papermaking, pharmacy.Common up flow anaerobic sludge blanket reactor (hereinafter to be referred as the UASB reactor drum) comprises reactor drum urceolus, water distributor, triphase separator, collection chamber, effluent trough, air outlet.Treatment sewage flows into the Sludge Bed district through water distributor; Organism in the microbiological degradation sewage in Sludge Bed district and be converted into biogas; Biogas produces and in uphill process, converges gradually increase with the micro-bubble form; Carry mud, water rises together and gets into triphase separator, after triphase separator carried out the solid, liquid, gas three phase separation, wherein gas phase was separated and get into behind the collection chamber by deriving the air outlet; The solid-state gravity settlement action that communicated goes back to the Sludge Bed district, and liquid phase water rises and overflows into the effluent trough discharge.
The UASB reactor drum was metal construction in the past, and the baffle plate of triphase separator is glass reinforced plastic, carbon steel, stainless steel or PVC plate, and these baffle plates need metalwork to fix; And baffle plate and fixing metal spare all are immersed in the sewage, owing to contain hydrogen sulfide in the biogas that produces, incorporate and present acidity in the water, hardware are had heavy corrosion property; And sewage also has corrosive character, and especially water temperature is greater than 25 ℃ in the UASB reactor drum, and galvanic corrosion is stronger; Make the metalwork of fixed dam be easy to erode like this; Cause the triphase separator baffle plate to fall in the UASB reactor drum, the triphase separator disabler, thus can not normally move; So influence UASB reactor drum operation stability, increased the workload of running maintenance.
Therefore have and to transform existing UASB reactor drum, to satisfy the requirements at the higher level in the operation.
The utility model content
The purpose of the utility model is to overcome the defective that common UASB reactor drum exists, and provides a kind of stable, is easy to safeguard, more economically the UASB reactor drum.
The purpose of the utility model realizes through the technical scheme that is described below:
A kind of UASB reactor drum comprises reactor body, water inlet, triphase separator, biogas chamber, biogas vapor pipe, mud district, and the overflow effluent trough is characterized in that: reactor body is a steel and concrete structure, and triphase separator is made up of diagonal brace baffle plate and separation center wall.
Single tube multiple spot water distribution is adopted in the reactor drum water inlet, and every pipe is provided with a valve.
UASB reactor drum biogas chamber is an independent air chamber.
UASB reactor assembly main body is a steel and concrete structure, and single tube multiple spot water-distributing is adopted in water inlet, and every pipe is provided with a valve, has washing function, and is stable, simple to operate.The water distribution material adopts the PVC material, and duration of service is long, need not safeguard basically.
Set inside triphase separator system is divided into three reaction zones with anaerobic reactor: first reaction zone (main reaction region), second reaction zone (settling region) and the 3rd reaction zone (clear water zone).
First reaction zone (main reaction region) be triphase separator with the lower section, this part is the major portion that anaerobic reactor plays a role, this part removed anaerobism remove CODcr 85% with top, methane content guarantees more than 55% in the biogas.This part is entirely granule sludge after the steady running, and aerogenesis and gas stirring are very violent.
Second reaction zone (settling region) is a part between the triphase separator; This part has following function: 1 because the interior biogas generation of first reaction zone is stirred extremely violent; The simple one-level triphase separator that relies on is difficult to a small amount of small-particle mud in the mud is effectively separated with floc sludge, will cause this part sludge loss like this.Even the anaerobic sludge number of dropouts is less; Also possibly influence treatment effect; Mud in the water outlet simultaneously also will influence the aerobic treatment effect, and because the gas stirring in second reaction zone is less, will hold back this part mud; Make its partial reflux go into first reaction zone, rest part is trapped in second reaction zone; 2 because biogas generation and stirring and violent in first reaction zone; The simple one-level triphase separator that relies on is difficult to the biogas that produces is separated fully; To cause this part biogas to run off like this; Promptly possibly reduce the recovery of the energy, possibly increase potential safety hazard simultaneously and influence the settling region sedimentation effect, the existence of second reaction zone will well separate this part biogas 3 owing to still have a certain amount of anaerobion in second reaction zone; So self the organism in the waste water is also had certain removal, its removal to organic pollutant accounts for about 15% of anaerobism part.
The 3rd reaction zone (clear water zone) is mainly used in and separates through still effusive anaerobic sludge behind the triphase separator, makes the anaerobic sludge post precipitation pass back into first and second two reaction zone.Water outlet SS after the processing is obviously reduced, and processing efficiency is increased effectively.
Mud in the UASB reactor drum, sewage and biogas are able to good the separation.Mud degassing postprecipitation can the Sludge Bed district, thereby is detained the anaerobion quantity in the reactor drum to greatest extent, and the sludge concentration under the usual conditions in the reactor drum is at 50g/L, more than, far above 3～4g/L of aerobic sludge.Biogas is collected through gas skirt, and sewage is discharged reactor drum by effluent trough after treatment.
Another characteristics of UASB reactor drum are be more prone to superior at its Sludge Bed district formation settling property, the granule sludge that specific activity is very high.Because the good settling property of granule sludge has reduced anaerobion significantly and has been rushed out the amount of reactor drum, thereby make the higher reactor drum height of concentration of anaerobic microorganisms in the whole reactor, improved the usefulness of reactor drum.On the other hand because the formation of granule sludge, strengthened hydrogen transference between the kind of anaerobic bacterium widely, improve the activity of mud, thereby improved the usefulness of reactor drum.
