Abstract
The utility model relates to a novel embedded integrated flow guiding biological aerated filter and belongs to the field of environmental protection equipment. The novel embedded integrated flow guiding biological aerated filter comprises a hydrolytic acidification region, a convection contact oxidation region, a flow guiding sedimentation recirculation region, an upflow aeration biological filtering region and a sludge recirculation system. The novel embedded integrated flow guiding biological aerated filter has the beneficial effects that hydrolysis and acidification reactions are carried out on microorganisms in water under anoxic condition (dissolved oxygen is less than 0.5mg/L), and macromolecule organic matters in water are decomposed into micromolecule organic matters easy to treat, so that biochemical property of sewage is improved; and mud-water mixture subjected to aerobic nitrification treatment returns to the hydrolytic acidification region, and ammonia nitrogen in water is converted into nitrogen under the action of denitrification of anaerobic bacteria at the moment, so that effluent quality is greatly enhanced.
Description
Technical field
Novel buried integrated water conservancy diversion BAF belongs to the environmental protection equipment field.
Background technology
Buried integrated water conservancy diversion BAF is to make sewage in same treating pond, finishes aeration-precipitation-processes such as secondary aeration-secondary sedimentation, and solving other sewage disposal needs four technical process that the pond just can be finished.Particularly under continuous water inlet condition, realize the gap aeration of water inlet-aeration-precipitation-water outlet.Its advantage is more outstanding than other sewage water treatment method, and treatment effect is particularly remarkable, and buried integrated water conservancy diversion BAF is AB method, SBR method, A
2It is two heavy that O method, contact oxidation method and two are exposed to the sun, the renewal product of sewage disposal devices such as intermittent aeration.Find that according to service condition this equipment is higher to the removal efficient of methods such as COD, BOD, SS, but lower to ammonia-N removal rate.
The primary structure of this equipment comprises: convection current catalytic oxidation district, water conservancy diversion sedimentation recirculating zone, upward flow biological aerated filter district etc.
Summary of the invention
This project is on the basis of existing buried integrated water conservancy diversion BAF, set up a round shape acidication district, hydrolysis and acidification reaction take place in sewage in hydrolysis acidification pool 3, larger molecular organics in the water is decomposed into tractable small organic molecule, improve the biodegradability of sewage; Set up a cover mud return-flow system simultaneously, the mud mixture part bottom the water conservancy diversion negative area is back to the acidication district.
Novel buried integrated water conservancy diversion BAF is characterized in that: be made up of acidication district, convection current catalytic oxidation district, water conservancy diversion sedimentation recirculating zone, upward flow biological aerated filter district and mud return-flow system; Sewage enters hydrolysis acidification pool, convection current contact-oxidation pool, sludge settling concentration basin, Up-flow Biological Aerated Filter successively, realizes sewage purification.
Described novel buried integrated water conservancy diversion BAF is characterized in that: the mud return-flow system is made of sludge reflux pump and shore pipe and mud return line; By the mud that sludge reflux pump flows out, a part is back to the acidication district, and another part effluxes and enters sludge digestion tank.
The beneficial effect of this project is that hydrolysis and acidification reaction take place microorganism (dissolved oxygen is less than 0.5mg/L) under anoxia condition in the water, and larger molecular organics in the water is decomposed into tractable small organic molecule, improves the biodegradability of sewage; The mud mixture of handling through aerobic nitrification is back to the acidication district simultaneously, in this denitrification by anaerobic bacteria flora the ammonia nitrogen in the water is converted into nitrogen, has promoted the water outlet quality greatly.

Accompanying drawing is the sectional view of novel buried integrated water conservancy diversion BAF.Visible water inlet pipe 1, water-distributing device 2, hydrolysis acidification pool 3, convection current contact-oxidation pool 4, flow deflector 5, Up-flow Biological Aerated Filter 6, rising pipe 7, sludge settling concentration basin 8, shore pipe 9, sludge reflux pump 10, mud return line 11, roots blower 12, inlet pipe 13, aerating apparatus 14, lightweight bio-carrier 15, access opening 16, sludge outlet 17 among the figure.
Embodiment
As shown in drawings,
During novel buried integrated water conservancy diversion BAF works better, sewage enters hydrolysis acidification pool 3 from water inlet pipe 1 uniformly through water-distributing device 2, lightweight bio-carrier 15 is housed in hydrolysis acidification pool 3, hydrolysis and acidification reaction take place in sewage in hydrolysis acidification pool 3, larger molecular organics in the water is decomposed into tractable small organic molecule, improve the biodegradability of sewage, finish the purpose that the first step is handled;
The water outlet of hydrolysis acidification pool enters convection current contact-oxidation pool 4, lightweight bio-carrier 15 also is housed in the convection current contact-oxidation pool 4, sewage is fully realized convection current contact, bio-oxidation and aeration filtration in stream contact-oxidation pool 4, aerobic bacteria is carrier with the filler, utilize the organism in the sewage to be foodstuff, organism in the sewage is resolved into inorganic salts, and most of organism obtains degraded and purification at this in the raw waste water, finishes the purpose that handle the second stage thereby reach;
Sewage is realized mud-water separation in sludge settling concentration basin 8 after, under the effect of flow deflector 5, from bottom to top, enter Up-flow Biological Aerated Filter 6, lightweight bio-carrier 15 also is housed in the Up-flow Biological Aerated Filter 6, sewage carries out abundant aeration at this, realize bio-oxidation and biofiltration, limpid water outlet behind the aeration filtration is flowed out by rising pipe 7, finishes the purpose that the third stage is handled thereby sewage is reached;
Sewage is in the treating processes of Up-flow Biological Aerated Filter 6, also will produce some mud, these mud are sunken to sludge settling concentration basin 8 under the gap by flow deflector 5 and equipment room under action of gravity, carry out concentrating and precipitating, realize that two aeration tanks share a settling tank;
The mud return-flow system is made of sludge reflux pump and shore pipe and mud return line.Be provided with mud discharging device 9 in the bottom of sludge settling concentration basin 8, mud mixture after precipitation concentrates is under the castering action of sludge reflux pump 10, by mud discharging device 9, a part effluxes by sludge outlet 17 and enters sludge digestion tank, another part enters mud return line 11 and is back to hydrolysis acidification pool 3, in this denitrification by anaerobic bacteria flora the ammonia nitrogen in the water is converted into nitrogen, is released in the air, to reach the purpose of removing ammonia nitrogen;
Sewage flows into follow-up sterilization basket automatically after novel buried integrated water conservancy diversion BAF is handled, sterilization can adopt the slow release type chlorine tablets to carry out disinfection.
Access opening 16 for make and during maintenance personnel pass in and out design.
