Description
Technical field
The present invention relates to a kind of sewage disposal system contact chamber water outlet detection technique, especially a kind of contact chamber effluent index detection method that can improve accuracy of detection.
Background technology
Contact chamber, has another name called disinfecting tank, is in the sewage disposal system of city domestic sewage treatment plant, sewage after sedimentation in secondary sedimentation tank to carry out disinfection the pond of reaction for adding liquid chlorine together before outer row.
The sewage that sewage disposal system is disposed, it can reach certain water quality standard, is called middle water, can arrange or recycle in addition.Therefore all need during sewage disposal system water outlet to detect, judge that can water outlet ss index (suspended solids content), colorimetry-turbidity etc. reach requirement.
When summer, inflow strengthened, usually can cause water outlet ss index and colorimetry-turbidity index exceeding standard, in order to reduce water outlet ss index, be generally by strengthening biological reaction pool, the treatment effect in the treatment process such as settling basin in prior art; Need to drop into larger cost.
Summary of the invention
For the deficiencies in the prior art, technical matters to be solved by this invention is, how providing a kind of with less cost, can reduce contact chamber water outlet detected parameters, improve the contact chamber effluent index detection method of effluent index accuracy of detection and reliability.
In order to solve the problems of the technologies described above, in the present invention, have employed following technical scheme:
A kind of contact chamber effluent index detection method, it is characterized in that, before water outlet detects, suspension defoaming device is set in the inlet passage of contact chamber to eliminate foam in water inlet current, and then eliminate foam to the impact of effluent index testing process, to reduce detected parameters and to improve detection accuracy.
Applicant researchs and analyses discovery, stage in summer, sewage foam volume is very large, further analysis sewage foam comprises bio foam and physical foam, bio foam produces primarily of the residual body particulate of dead mud of the residual body of der Pilz and a small amount of flocculating settling characteristics difference, physical foam mainly in water body flow process because the reasons such as disturbance drop produce.Because sewage industry ss mensuration is that the mode adopting 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; Result in detecting reliability difference, Testing index easily exceeds standard.Therefore applicant have employed the technological means arranging suspension defoaming device to eliminate water inlet foam in contact chamber inlet passage, avoid foam to the impact detected, and then reach reduction contact chamber water outlet detected parameters, improve the effect of effluent index accuracy of detection and reliability.
As optimization, described suspension defoaming device, comprise the support frame that an entirety is rectangular, support frame width and the first inlet passage width mate and the float support that corner is fixed on lower side is bubbled 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; In suspension defoaming device, also comprise the clad steel silk screen being arranged on support frame rear end, immerse below the water surface before described double-layer wire half portion off the net is oblique, woven wire adopted the woven wire of 80 order mesh; When suspension defoaming device uses, de-bubble brush is used for tentatively smashing water surface foam and driving water-bed foam to float, and clad steel silk screen remains foam and after a period of time collection completely, by manually salvaging cleaning for tackling to assemble.
After such optimization, when the suspension defoaming device of employing uses, water impact de-bubble brush rotates, and like this, the foam of water surface can be broken up by de-bubble brush, tentatively eliminates foam; The foam that part is not smashed by de-bubble brush and part are driven the foam floating to the water surface from current bottom all to be assembled by woven wire interception by the current that de-bubble brush rotates, and after a period of time collection completely, manually can salvage cleaning, improve de-bubble effect better.Wherein, woven wire adopts double-deck settings and bottom turns forward, and when can improve the congregational rate of foam and be convenient to salvaging, foam is attached on woven wire, conveniently salvages cleaning.Woven wire adopts the woven wire about 80 orders, can guarantee congregational rate preferably.Therefore after optimizing, drastically increase de-bubble effect, ensure that contact chamber effluent index detection accuracy.
As optimization, be designed to the inlet passage of contact chamber to comprise be linked in sequence the first inlet passage between second pond junction box and contact chamber and the second inlet passage, described second inlet passage is folded to the first inlet passage and is connected, and the second inlet passage width is greater than the first inlet passage width; Described suspension defoaming device is designed in the first inlet passage, and de-bubble mechanism is set in the second inlet passage water inlet place carries out de-bubble.
Two inlet passages are folded to connected, can energy dissipating better, and the second inlet passage width is larger simultaneously, thus current enter the second gallery after water speed slow down, avoid current too urgent and produce new bubble; Better can ensure the hydraulic detention time in contact chamber simultaneously, avoid the too urgent impact on contact chamber of current, guarantee Disinfection Effect, improve and finally detect percent of pass.
As optimization, described de-bubble mechanism comprises the water pipe be horizontally installed on the second inlet passage water inlet place Width gallery wall, and water pipe is provided with a discharge (operating) water nozzle obliquely along the second inlet passage water (flow) direction, and water pipe is connected with intermediate water pipeline system; Also comprise the energy dissipating baffle plate being positioned at the second inlet passage water inlet, the described vertical bottom of energy dissipating baffle plate there is not upstream face and is positioned at the first half position of water inlet flow section, and energy dissipating baffle plate is evenly distributed with flowing hole; During use, energy dissipating baffle plate is used for energy dissipating and slows down water speed and the follow-up current of energy dissipating baffle plate are sprung up from the bottom up, the foam that current depths is hidden emerges and is broken by the current that water pipe penetrates, guaranteeing better de-bubble effect.
Like this, energy dissipating baffle plate can 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 sprung up from the bottom up, avoids broadening due to the second inlet passage and producing down stream and whirlpool in its water inlet place after being folded to and sweep across into air produces bubbles.Meanwhile, after energy dissipating baffle plate makes follow-up current spring up from the bottom up, the foam that current depths can be made to hide emerge and is broken by the current that water pipe penetrates, guaranteeing better de-bubble effect; And then reduce contact chamber water outlet detected parameters, can be up to standard better.
In sum, the present invention without the need to improving water technology, but avoids foam on the impact detected in the mode arranging defoaming device elimination foam, can with less cost, reduce contact chamber water outlet detected parameters, improve effluent index accuracy of detection and reliability, improve and detect compliance rate.
