Description
Technical field
The present invention relates to a kind of Sewage treatment systems contact tank inlet passage, especially a kind of contact tank inlet passage de-bubble system.
Background technology
Contact tank, has another name called in the Sewage treatment systems of disinfecting tank ，Shi city domestic sewage treatment plant, sewage after second pond precipitation to the pond that carries out disinfection and react for adding liquid chlorine together before outer row.
The sewage that Sewage treatment systems is disposed, it can reach certain water quality standard, is called middle water, can arrange or recycle in addition.Therefore all need during Sewage treatment systems water outlet to detect, can judgement water outlet ss index (suspended solids content), colorimetry-turbidity etc. reach requirement.
In the situation that summer, flooding quantity strengthened, usually can cause water outlet ss index and colorimetry-turbidity index exceeding standard, in order to reduce water outlet ss index, in prior art, be generally by strengthening biological reaction tank, the treatment effect in the treatment process such as settling tank; Need to drop into larger cost.
Applicant studies discovery, and in the stage in summer, sewage foam volume is very large.Analyze after deliberation, sewage foam comprises bio foam and physical foam, and bio foam is mainly produced by the residual body of thread fungus and a small amount of poor residual body particulate of dead mud of flocculating settling characteristics, and physical foam is mainly because the reasons such as disturbance drop produce in water body flow process.Because sewage industry ss measures, be that the mode that adopts filtration to weigh is measured, therefore wherein bio foam can affect ss index size; Foam particles is mingled in water simultaneously, can cause the increasing of colorimetry-turbidity; Caused index exceeding standard.
Therefore be necessary to consider how to design a kind of de-bubble system, to eliminate foam, and then reduce the impact of foam on effluent index, improve effluent characteristics.
Summary of the invention
For the deficiencies in the prior art, technical problem to be solved by this invention is how to provide a kind of and can eliminate efficiently foam, and then reduce the impact of foam on effluent index, the contact tank inlet passage de-bubble system of raising effluent characteristics.
In order to solve the problems of the technologies described above, in the present invention, adopted following technical scheme:
A kind of contact tank inlet passage de-bubble system, it is characterized in that, comprise the first inlet passage and the second inlet passage that are linked in sequence between second pond junction box and contact tank, in described the first inlet passage, be provided with suspension defoaming device, described the second inlet passage water inlet place is provided with de-bubble mechanism; Described suspension defoaming device comprises a support frame that integral body is rectangular, support frame width and the first inlet passage width coupling and four jiaos of fixing floats of lower side support bubbles through the water column, support frame ties up on the gallery wall of the first inlet passage by static line, support frame is horizontally arranged with a de-bubble brush in face of the front end of water (flow) direction, de-bubble brush two ends are rotatably connected on support frame, the bristle of de-bubble brush bottom immerses underwater, and the bristle that de-bubble brushes portion surfaces; Described de-bubble mechanism comprises the water pipe being horizontally installed on the second inlet passage water inlet place width gallery wall, and on water pipe, along the oblique discharge water spouting nozzle that is arranged with of the second inlet passage water (flow) direction, water pipe is connected with intermediate water pipeline system.
In de-bubble system of the present invention, when suspension defoaming device is used, the rotation of water impact de-bubble brush, like this, de-bubble brush can be broken up the foam of water surface, tentatively eliminates foam.In the second inlet passage water inlet place, be provided with de-bubble mechanism, in de-bubble mechanism, adopt the water pipe being connected with intermediate water pipeline to impact the water surface, further eliminate foam, reached the object of eliminating foam, reduce the impact of foam on effluent index simultaneously.
As optimization, in described suspension defoaming device, also comprise a Clad Steel silk screen that is arranged on support frame rear end, the oblique front immersion water surface of described double-layer wire net Lower Half below.
Like this, Clad Steel silk screen can produce congregation to foam, make foam and part that part is not smashed by de-bubble brush be driven the foam that floats to the water surface from current bottom all by woven wire interception, to be assembled by the current of de-bubble brush rotation, when for some time collection completely after, can manually salvage cleaning, improve better de-bubble effect.Wherein, woven wire adopts settings that turn forward of bilayer and bottom, and when can improve the congregational rate of foam and being convenient to salvage, foam is attached on woven wire, and convenient salvaging cleared up.During concrete enforcement, woven wire adopts the woven wire of 80 order left and right, can guarantee preferably congregational rate.
As optimization, described the second inlet passage is folded to and is connected with the first inlet passage, and the second inlet passage width is greater than the first inlet passage width.
After optimizing like this, it is connected that two inlet passages are folded to, energy dissipating better, and the second inlet passage width is larger simultaneously, therefore water speed slows down after current enter the second gallery, avoids current too urgent and produce new bubble; Can better guarantee the hydraulic detention time in contact tank, avoid the too urgent impact on contact tank of current, guarantee sterilisation effect simultaneously.
As further optimization, in described de-bubble mechanism, also comprise the energy dissipating baffle plate that is positioned at the second inlet passage water inlet, the vertical bottom of described energy dissipating baffle plate there is not upstream face and is positioned at the first half position of water-in flow section, on energy dissipating baffle plate, is evenly distributed with flowing hole.
Like this, energy dissipating baffle plate better energy dissipating to slow down water speed; Simultaneously the position of energy dissipating baffle plate, makes the follow-up current of energy dissipating baffle plate present the feature springing up from the bottom up, avoid due to the second inlet passage broaden and be folded to after in its water inlet place, produce down stream and whirlpool and sweep across into air and produce bubble.Meanwhile, after energy dissipating baffle plate springs up follow-up current from the bottom up, can make the current that emerge on the hiding foam in current depths and penetrated by water pipe break, guarantee better de-bubble effect.
In sum, de-bubble system of the present invention, can eliminate foam very efficiently, and then reduces the impact of foam on effluent index, has improved contact tank effluent characteristics.
