Description
Technical field
The invention belongs to a kind of technical field of sewage, concrete is a kind of modifying device of the SBR of use sewage treatment process.
Background technology
SBR technology is a kind of sequence batch (sewage second-level treatment process.From whole technological process, SBR process using intermittent operation mode, the sbr reactor pond is in the different effect of different time performance, this technology is divided into into water, aeration, precipitation, these four sequential of water outlet (spoil disposal can be incorporated the water outlet sequential into) with treating processes, finishes these four used times of sequential to be called the cycle.First sequential is water inlet, and sewage enters in this period in the treating pond continuously, until reaching the highest operation liquid level; Second sequential is aeration, and the also not draining of not intaking in this period is the reaction tank aeration but open aerating system, and this moment, pollution substance carried out the biochemistry decomposition; The 3rd sequential do not intake or draining in this period for precipitation, also aeration not, and reaction tank is in quiet heavy state, carries out efficient mud-water separation; The 4th sequential is draining, in this period separated liquid supernatant discharged continuously by straining hydrophone, strains hydrophone and slowly descends under hydraulic power, and liquid level also descends thereupon in the pond, and the left-falling stroke water yield is dark in 1/6～1/4 pond, discharges excess sludge simultaneously.SBR technology has obtained engineering application widely now, owing to no second pond and returned sluge system in its technology, also can not establish preliminary sedimentation tank, thereby the civil engineering investment is low, takes up an area of also few.But the hydrophone of straining of traditional SBR technology is a kind of hydro-mechanical unit by autocontrol operation, poor reliability, and facility investment is bigger, and failure rate and maintenance capacity are also bigger.In addition, it is huge to strain the equipment volume of hydrophone; Disturbance sludge blanket during water outlet, the effluent quality instability; Can't be installed on the biological reaction tank of top cover sealing, surrounding air environment is affected, in some residential quarters, hotel etc. use than higher place environmental quality requirement and are restricted.Therefore, need improve, reduce cost and running cost, make the surface structures facility unrestricted this technology.
The utility model content
The purpose of this utility model is in order to solve the problems of the technologies described above, to propose a kind of SBR process spent water treatment unit.This device is improved on the basis of traditional SBR, cancel the hydrophone of straining of traditional SBR technology, adopted novel center water injection allocator water inlet, the structure formation of fixed overfalling weir water outlet, save electromechanical equipment, make technological process be reduced to into water jacking water outlet, aeration, three sequential of precipitation spoil disposal.
The purpose of this utility model is achieved through the following technical solutions: SBR process spent water treatment unit, be provided with reaction tank, be provided with aeration head at the bottom of the pond, aeration head is communicated with gas blower, it is characterized in that: described reaction tank is the structure of vertical sedimentation basin, the upper edge of reaction tank is provided with overfalling weir, central vertical at reaction tank is provided with the center water injection allocator, this water injection allocator is made of core barrel and reflector, the upper end of water injection allocator is communicated with intake pump, is provided with the shore pipe that is communicated with sludge pump in the bottom for the treatment of pond.
The design requirements of reaction tank: available depth is not less than 4m; The diameter or the length of side should≤8m, if the diameter or the length of side greater than 8m, hydraulic load q≤1m then
3/ m
2/ h.
The design requirements of center water injection allocator: central tube design current velocity v≤0.03m/s; The hydraucone diameter is 1.25 times of central tube diameter; Reflector is not less than 1m at the bottom of the pond, be not less than 0.3m apart from the mud face.
The design requirements of overfalling weir: q≤1.7L/s/m loads on the weir; Weir notch should meet the design requirements of rectangular flow tank, and the depth of water must not surpass 2/3 of groove depth.
Compare device of the present utility model with the device of traditional SBR technology and have following advantage:
(1) structure formation of vertical sedimentation basin is adopted in the sbr reactor pond, the not short stream of Inlet and outlet water.
(2) adopt the center water distribution, water inlet evenly prevents from sludge blanket is invaded and harassed, and effectively avoids water outlet to carry mud secretly. under the constant situation of cycle, and the time lengthening of aeration, biochemical reaction is more abundant, and effluent quality is better.The appropriate change automatic program can also be realized denitrogenation dephosphorizing at any time;
(3) cancelled the hydrophone of straining of traditional SBR technology, adopted novel center water injection allocator water inlet, the structure formation of fixed overfalling weir water outlet saves electromechanical equipment, makes technological process be reduced to into water jacking water outlet, aeration, three sequential of precipitation spoil disposal.Reduced facility investment, the maintenance of the equipment amount also reduces, and delivery turbidity reduces, the biochemical reaction time lengthening, and effluent quality is better; The automatic control process is stable more, reliable, can realize unmanned.Not only reduce construction cost, also greatly reduced running cost.
(4) new structure formation need not be safeguarded because of there not being dynamo-electric equipment, is convenient to build up the biological reaction tank of sealing, can adopt complete underground incorporate construction style, and building and facility on the ground is unaffected, has started the new concept of fully buried sewage work station design.The apparatus and method of New type of S BR technology can be applied in some residential quarters, hotel etc. to environmental quality requirement than higher place.
