Description
Technical field
The utility model relates to a kind of waste disposal plant, refers in particular to a kind for the treatment of device for sludge self-return aerobic bios.
Background technology
At present for small-scale sewage treatment facility, because its sewage water yield is little, if adopt traditional aerobic process that several necessary processing structures such as aeration tank, settling tank, sludge thickener must be arranged, also need to set up power-equipments such as sludge reflux pump, its ton water investment cost is very high, but also be easy to generate phenomenon such as sludge bulking, therefore be not suitable for being applied to small-scale sewage treatment facility.
Application for a patent for invention 200610036025.2 discloses a kind of integrated self-refluxing multi-stage biochemical sewage treatment device, this device comprises anaerobic zone, be provided with the sewage import in the bottom of anaerobic zone, the oxygen-starved area, be provided with partition wall between itself and the anaerobic zone, aerobic zone, the bottom of aerobic zone is connected with the oxygen-starved area, bottom at aerobic zone is equipped with aerating apparatus, the settling region, the bottom of settling region is provided with oblique bucket, and tiltedly bucket communicates with aerobic zone, tiltedly bucket is arranged to rely on the mud self gravitation that mud is glided to the aerobic zone bottom, and the top of settling region is provided with and overflows tank.This technical scheme aerobic zone directly links to each other with the settling region, be that water outlet and mud reflux at the same area, when handling the water yield when big, promptly current enter the upflow velocity of settling region and can produce mud when very fast and can not in time reflux, cause mud to gather, cause the generation of mud rising phenomenon in the settling region.
Summary of the invention
The utility model provides a kind of compact construction is simple, floor space is little, processing efficiency is high precipitation, aeration and mud are refluxed automatically in the treating device for sludge self-return aerobic bios of one.
A kind for the treatment of device for sludge self-return aerobic bios, comprise the pond body, body two ends, pond are respectively equipped with water-in and water outlet, are provided with in the body of described pond by water inlet flow deflector, dividing plate to separate but water conservancy diversion district, aeration zone and the sludge settling district of bottom connection, and the bottom, aeration zone is provided with aerating apparatus; Bottom, sludge settling district has intilted bucket swash plate, and sludge settling is provided with traverse baffle in the district, and the middle and lower part in sludge settling district is provided with some mudholes, and top is provided with the water outlet overflow weir, and the water outlet overflow weir is connected water outlet.
Described water inlet flow deflector lower end is provided with the flow guiding inclined plate that becomes 45-60 degree angle with horizontal plane.
Described dividing plate upper end has mud baffling buffering swash plate, and the lower end has the flow guiding inclined plate that becomes 120-135 degree angle with horizontal plane.
Described traverse baffle lower end has the swash plate flow deflector.
The length of described mud baffling buffering swash plate is 1: 0.8～1.2 with the width ratio in water conservancy diversion district, and it becomes 15-30 degree angle with horizontal plane.
The width of described traverse baffle is the key parameter of decision descent waterflow flow velocity, width is too little, the resistance that produces too conference influences the circulation of mud, width too conference influences the volume effective rate of utilization of reactor, its width is suitably adjusted according to the increase of treatment sewage waterpower decline flow velocity herein and is widened, and the flow velocity that waterpower descends generally is controlled at 0.1-0.8m/s.
The height of described water outlet overflow weir (9) upper end is higher than the height of dividing plate (14) upper end
The angle setting of described bucket swash plate is bigger than the angle of general settling tank bucket, be to enter the aeration zone then in order to allow the mud of settling region be slipped to the bottom, settling region smoothly automatically, so its swash plate angle becomes the 100-125 degree to be advisable with level.
The setting of described mudhole height is an important parameter of decision aeration tank sludge concentration, traditional aerobic process needs managerial personnel to control mud to reflux and guarantee the sludge concentration of Aerobic Pond, and in the design, can determine that the aeration tank sludge concentration designed the height of mud discharging mouth afterwards by the designer, and managerial personnel only need be discharged to mud till the mud discharging mouth.General sludge concentration according to the aeration tank is arranged on mud discharging mouth from the place of bottom 1/3-1/4 is advisable.
The utility model with the fusion of the two diverse flow shape success in a structure body, and under the prerequisite that satisfies functional requirement separately, realized that mud refluxes automatically, the particularly setting of mud baffling buffering swash plate, can reduce aeration tank mud flow velocity, reduced the settling tank load, can allow again the mud mixture that runs off from the aeration zone comparatively mild enter the settling region, minimizing forms whirlpool in the baffling district, successfully solved a difficult problem that causes to be successfully applied to the small-scale sewage treatment facility because of the aerobic process structures are comparatively various, save mud refluxing unit and power charge, and effectively prevented the generation of sludge bulking phenomenon.The utility model apparatus structure is compact simple, and floor space is little, and the processing efficiency height is particularly suitable for being applied to sewage treatment facility on a small scale.
