Abstract
The utility model provides a double-water-inlet sequencing batch reactor (SBR) for cultivating aerobic granule sludge, which is more favorable for the cultivation of the aerobic granule sludge. The SBR comprises an SBR main body, an aeration system and a stirring system, wherein the stirring system is arranged in the SBR main body; the aeration system comprises a microporous aerator, an air compressor and an aeration hose; an upper water inlet (5) is formed in the upper part of the SBR main body; a lower water inlet (4) is formed in the lower part of the SBR main body; a sludge outlet (3) and an emptying opening (2) are formed in the lower part of the SBR main body (1); and a water outlet (6) is formed in the middle of the SBR main body (1) and connected with a water tank. Water flows into the SBR through the two water inlets at the same time, so as to solve the problem that muddy water in an SBR with larger height-diameter ratio is mixed unevenly, and facilitate the cultivation of the aerobic granule sludge.
Description
Technical field
The utility model relates to experimental installation in a kind of biological wastewater treatment field, is specifically related to the sbr reactor device that a kind of pair of water-in cultivated aerobic particle mud.
Background technology
Because the quick dramatic growth of population, industry constantly develops, and the quantity discharged of municipal effluent and trade effluent also grows with each passing day.And the concentration of nitrogen and phosphorus in the sewage is higher, and the effluent quality that traditional activated sludge process is handled is difficult to satisfy the requirement of emission standard, and the denitrification dephosphorization technique that therefore need seek a kind of economical and efficient becomes the emphasis problem of countries in the world water pollution control area research.
It is the topmost method of wastewater treatment that the aerobe of sewage is handled, and is widely used in municipal effluent and the technique for treating industrial wastewater.In recent years, a kind of novel aerobe treatment technology---aerobic particle mud becomes the focus of sewage treatment area research.Compare with common cotton-shaped active sludge, it is good that aerobic particle mud has a settling property, and sludge concentration is high, advantages such as anti impulsion load.And through directed domestication, aerobic particle mud not only can be removed the organism in the sewage, can also realize denitrogenation dephosphorizing and the pollutent of removing some difficult degradations.Therefore, the hard-degraded substance that utilizes aerobic particle mud to solve in body eutrophication and the degraded trade effluent is the emphasis that current scholars study.
Most scholar adopts the sbr reactor device at present, inoculates cotton-shaped active sludge therein, obtains aerobic particle mud through the control culture condition.In many conditions of cultivating, the aspect ratio of sbr reactor device is to the pelletising process important influence of aerobic sludge.Bigger aspect ratio helps the prilling of aerobic sludge, but because height of devices is bigger, and diameter compares less, and the draining ratio is generally 50%-70%, therefore, a water-in only is set is unfavorable for that water into mixes with mud among the SBR.
Summary of the invention
Mix uneven problem in order to solve muddy water; The utility model provides a kind of New type of S BR device; This device is in the upper and lower of common SBR device water-in to be set respectively, and two water-ins are intake simultaneously, forms convection current; Make the muddy water better mixing even, more help the culture successful of aerobic particle mud.
The utility model solves the technical scheme that its technical problem adopted: it comprises SBR main body reactor drum, aerating system and stirring system, and stirring system places the main body inside reactor; Aerating system is made up of micro porous aeration head and air and aeration flexible pipe, and it is characterized in that: said SBR main body reactor drum is provided with top water-in 5, and the bottom is provided with lower water inlet 4, and mud discharging mouth 3 and drain 2 are arranged at SBR main body reactor drum 1 bottom; Water outlet 6 is driven the connection water tank at SBR main body reactor drum 1 middle part.The high 130cm of SBR main body reactor drum, diameter 9cm is the bigger sbr reactor device of aspect ratio.
The beneficial effect of the utility model is, up and down two water-ins intake simultaneously can make water into better with SBR in mud mix, do not have the dead band, help the culture successful of aerobic particle mud.The sbr reactor device muddy water that has solved larger ratio of height to diameter mixes uneven problem.
Description of drawings
Fig. 1 is the structural map that two water-ins are cultivated the SBR device of aerobic particle mud.
1SBR main body reactor drum, 2 drains, 3 mud discharging mouths, 4 lower water inlets, 5 top water-ins, 6 water outlets, 7 whisking appliances, 8 water inlet elevated tanks, 9 liquid meters, 10 air, 11 gas meters, 12 aeration heads, 13 go out water tank.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
The aerobic particle mud culture apparatus of the utility model is to be respectively equipped with water-in 4 and 5 on the bottom and the top of common SBR main body reactor drum 1, drain 2, mud discharging mouth 3, water outlet 6.The high 130cm of SBR main body reactor drum, diameter 9cm, water-in 5 gets into SBR main body reactor drum 1 with lower water inlet 4 to the sewage in the water inlet elevated tank 8 simultaneously from top through liquid meter 9, with the mud thorough mixing in the SBR main body reactor drum.The good section of supporting provides oxygen through gas meter 11 through aeration head 12 by air 10, and the anaerobism section makes mud be in suspended state through whisking appliance 7.
