A basin body is partitioned into four areas through two three-phase separators and partition plates in the vertical direction, wherein the four areas include the anaerobic sludge area (1), the anoxic sludge area (2), the aerobic sludge area (3) and a clean water area (14). The three-level double-internal-circulation biological sludge reactor has the advantages of being small in occupied land area and investment, convenient to install, high in shock resistance, stable in water outlet, low in operation cost, high in automation degree, easy and convenient to operate, good in nitrogen and phosphorous removing effect and capable of being used for high-concentration industrial waste water treatment, activated sludge reduction and removing of CODcr, total nitrogen, ammonia nitrogen and P in living sewage, hospital sewage and other similar low-concentration sewage.
Description
Technical field
The present invention is applicable to high-concentration industrial-water process, sludge decrement; Also the similar sewage of low concentration process of sanitary sewage and hospital sewage and other is applicable to.May be used for COD
cr, total nitrogen, ammonia nitrogen and P removal.Relate to anaerobism, double oxygen and the process of aerobic three stage microorganism organics removal and the device of two internal recycle granule sludge technology.
Background technology
In recent years Environmental Protection in China technology has very large development, and the technology in sewage disposal is varied.In biochemical treatment, internal circulating anaerobic granule sludge technology is widely used, and most typical technique has UASB and IC; Aerobic Granular Sludge Technology is in development, and the case being applied to Practical Project yet there are no.Granule sludge technology can make sewage sludge fully mix and keep quite high microbial biomass, avoids the short flow phenomenon of water distribution in traditional reactor simultaneously, improves reaction efficiency, thus makes the volume reducing of biochemical reaction container.Sewage by the reaction process of anaerobism, oxygen of holding concurrently, aerobic, double oxygen, is conducive to the removal of nitrogen phosphorus successively.Internal recycle granular sludge reactor aspect ratio is large, decreases floor space and civil engineering.
The COD of single internal circulating anaerobic particulate matter sewage sludge reactor water outlet
crthe requirement of environment protection emission is can not meet etc. index; At removal nitrogen phosphorus functionally, the treatment effect of internal circulating anaerobic particulate matter sewage sludge reactor is failed to understand.Although existing aerobic activated sludge process and improved technology good to the organic matter removal effect in low concentration sewage, but need multistage backflow when denitrogenation dephosphorizing, and the removal effect of total nitrogen and total phosphorus is unsatisfactory, consume energy consumption larger, the floor space of structures is large, build and processing cost higher.
Summary of the invention
The present invention is the integrated technique combining internal circulating anaerobic granule sludge technology, Aerobic Granular Sludge Technology, active sludge technology and shallow layer settling technology, solve the deficiency of above-mentioned biochemical technology, thus make the floor space of equipment little, the electromechanical equipment used is few, run and simplify, energy consumption reduces, and treatment effect is obvious, and investment and running cost reduce.COD in the similar sewage of low concentration of high-concentration industrial-water process, sludge decrement and sanitary sewage and hospital sewage and other can be applied to by the parameter controlling reactor
cr, total nitrogen, ammonia nitrogen and P removal.
The present invention is divided into anaerobic sludge zone, Jian Yang mud district, aerobic sludge district and four, clear water zone part from bottom to up successively, and device profile is circular or distance shape.Composition characteristic is: pond body is four regions in vertical direction by two triphase separators and baffle for separating, is followed successively by anaerobic sludge zone (1), Jian Yang mud district (2), aerobic sludge district (3), clear water zone (14).Anaerobism solid-liquid-gas three-phase separator (4) is had in the top of anaerobic sludge zone (1); There is aerobic solid-liquid-gas three-phase separator (5) top, aerobic sludge district (2); Body top, pond has anaerobism to promote liquid air water separator (6) and aerobic lifting liquid air water separator (7).Anaerobism solid-liquid-gas three-phase separator (4) there is anaerobism promote liquid upcast (8) and enter anaerobism lifting liquid air water separator (6); Aerobic solid-liquid-gas three-phase separator (5) there is aerobic lifting liquid upcast (9) enter aerobic lifting liquid air water separator (7).Anaerobism promotes liquid air water separator (6) bottom has anaerobism lifting liquid downtake (10) to be connected with anaerobic water system (12); Aerobic lifting liquid air water separator (7) bottom has aerobic lifting liquid downtake (11) to be connected with double oxygen water distribution system (13).Have dividing plate (15) between Jian Yang mud district (2) and aerobic sludge district (3), have water inlet pipe (16) bottom the body of pond, oxygenating system (17) is arranged at aerobic sludge district (3) bottom, and there is rising pipe (18) in clear water zone (14) outside.

specific embodiments:
Below operation scheme is illustrated with reference to the accompanying drawings
Case study on implementation: the sewage through pre-treatment enters anaerobic sludge zone (1) by water pump lifting by water inlet pipe (16).Different with concentration according to water inlet kind; granulating anaerobic sludge or cotton-shaped anaerobic sludge is dropped in advance in anaerobic sludge zone; by controlling the residence time and the upflow velocity of wastewater influent, one section or all processes being hydrolyzed in the presence of anaerobion in acidifying and methane phase process.Intake and after anaerobion is decomposed, to produce the gas such as methane generate bubble and be mixed in granule sludge and form mud group.The proportion of mud group is now less than the proportion of water, and therefore mud group can straight toward rising in anaerobism solid-liquid-gas three-phase separator (4).Here mud group and anaerobism solid-liquid-gas three-phase separator (4) collide and change the flow direction, bubbles burst, the mud group of air water and granule sludge composition dismisses, and the gas entrainment part steam such as methane promote liquid upcast (8) through anaerobism and enter anaerobism lifting liquid air water separator (6).Promote air water in liquid air water separator (6) in anaerobism to be separated completely, the gases such as methane are recycled after subsequent disposal, and the water carried secretly promotes liquid downtake (10) through anaerobism and enters anaerobic water system (12) circulation.Sink to bottom, anaerobic sludge zone (1) after granule sludge is degassed again to mix with water inlet.Intake and enter Jian Yang mud district (2) through anaerobism solid-liquid-gas three phase device (4) and be again hydrolyzed after acidifying and enter aerobic sludge district (3).Use external blower to provide oxygen in aerobic sludge district (3), the organism major part in sewage is resolved into carbonic acid gas and water by microorganism exhaustive oxidation in this region, and itrogenous organic substance matter carries out nitration reaction.The muddy water gas mixture in aerobic sludge district (3) carries out the separation of air water mud through aerobic solid-liquid-gas three-phase separator (5), residual gas after separation enters aerobic lifting liquid air water separator (7) with part steam by aerobic lifting liquid upcast (9) and is separated, water after degassed enters the circulation of double oxygen water distribution system (13) through aerobic lifting liquid downtake (11), and mixing water carries out anti-nitration reaction at this.The water outlet of aerobic solid-liquid-gas three-phase separator (5) enters after clear water zone (14) is collected discharges through rising pipe (18).
The feature of three grades of two internal recycle biological sludge reactors is: form anaerobism, double oxygen, aerobic and precipitation four regions in vertical direction, mud and sewage are all refluxed by internal recycle, without the need to additionaling power, the energy expended when having saved refluxing unit and run; Anaerobic grain sludge, aerobic particle mud, anaerobism floc sludge and aerobic activated sludge can be run in a reactor simultaneously.
