Description
Technical field
The utility model belongs to a kind of sewage disposal technology, specifically is that a kind of sewage treatment plant inflow distributes the device of regulating, and each handles the amount of inlet water of series to be used for balanced sewage work.
Background technology
The water inlet of large-scale wastewater treatment plant is by water distribution system, and water distribution handles series for parallel each, or is processing unit.Because each handles the distance of series and distributing well or different with the distance of water inlet manifold, and each handles the resistance of ducting difference of series, and it is inhomogeneous to cause each to handle serial water distribution easily, influences final treatment effect.In addition, each handles the aeration of the biological processing unit of series large-scale wastewater treatment plant, generally provide by total aeration tube, the unbalanced big processing series aeration deficiency of the water yield that causes of water distribution, the processing series aeration surplus that the water yield is little, the deficiency of aeration and surplus all can influence microbic activity, make the effluent quality variation.Simultaneously, the inequality of water distribution quantity can cause the difference of respectively handling serial water level, influences the back pressure of aerating pipelines, and the serial oxygen supply aerating system that water level is high need overcome the extra back pressure that high-water brings, and has improved the energy consumption of blower fan.Therefore, but adopt weir transfer to regulate and control the device of the water yield, the properly distributed water yield is managed series everywhither, operating performance is improved in sewage work have practical significance with the reduction aeration energy consumption.
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 sewage treatment plant inflow weir-adjustable control device, reaching better wastewater treatment efficiency, and reduces aeration energy consumption, guarantees that operating safety is efficient.
The purpose of this utility model is to realize by following technical scheme:
Sewage treatment plant inflow weir-adjustable control device of the present utility model, be provided with Aerobic Pond, in Aerobic Pond, be provided with the aerating apparatus of forming by aeration head, pipeline group, controlled motorized valve and gas blower, and be provided with online dissolved oxygen concentration meter and dissolved oxygen controller, dissolved oxygen controller carries out signal with online dissolved oxygen concentration meter and is connected, and carries out control linkage with controlled motorized valve; Described Aerobic Pond is arranged on sewage disposal series, or cries in the sewage disposal unit; It is characterized in that: also be provided with into water weir notch, be provided with the weir plate of the weir notch current that are used for damming in this water inlet weir notch, this weir plate top is provided with the weir transfer controller and the weir plate transmission mechanism of control weir plate lifting, and described weir transfer controller and described controlled motorized valve carry out signal and control linkage; This water inlet weir notch is provided with sewage inlet and water outlet, and water-in is connected with the sewage water inlet manifold of sewage work, and water outlet is communicated with the water-in of sewage disposal series; Described weir plate is the compoboard that individual plates or polylith plate make things convenient for assembly unit ground to constitute, and vertically is installed in the into bottom of water weir notch, leaves the space between weir plate both sides and the water inlet weir notch two side.
The technology of above-mentioned sewage treatment plant inflow weir-adjustable control device of utilizing of the present utility model may further comprise the steps:
1) starts the inflow weir-adjustable control device of each treatment system, promptly start the dissolved oxygen controller and the weir transfer controller of each inflow weir-adjustable control device;
2) behind the startup dissolved oxygen controller, in the controller of dissolved oxygen controller, set upper and lower limit, comparison interval time, the moving valve single motion opening value of dissolved oxygen concentration;
3) online dissolved oxygen concentration meter obtains the dissolved oxygen measured signal automatically, and gives dissolved oxygen controller with signal feedback, compares by pitch time, according to comparative result the motorized valve aperture is adjusted;
4) behind the startup weir transfer controller, in controller, set the moving amplitude of upper and lower limit, comparison interval time, weir transfer plate single of motorized valve aperture;
5) the weir transfer controller obtains the opening value signal of motorized valve from motorized valve, and in controller, the actual opening value of motorized valve and the aperture upper limit value and lower limit value of setting compared by pitch time, and according to comparative result weir plate were adjusted;
Weir plate structure of the present utility model has following characteristics: weir plate is dismantled and assembled form, is assembled into the monoblock weir plate by vertical monolithic weir plate, and the both sides weir plate is not installed generally speaking, can be according to adjusting the quantity that the water yield increases or weir plate is installed in the needs adjustment of minimizing.When this handles the series maintenance, all weir plates can be installed, form whole weir plate, substitute inlet gate, play the into effect of water of blocking.The mounting center weir plate during operation of regulating pondage device, the both sides weir plate is not installed, but main principle is the frequent adjusting for fear of weir transfer, because sewage work's water yield exists season crackization, monthly variation, daily variation, time to change etc., water yield variation can cause the variation of the preceding water level of weir plate, perforate is left in the weir plate both sides, the open area of weir plate two side hole also can change thereupon when change of level, streamflow was changed, play the function of regulating streamflow, thereby avoided the frequent keying of weir plate.
The cardinal principle of this device is the dissolved oxygen signal according to the aeration tank, adjust the aperture of the controlled motorized valve of aerated conduit, the adjustable control device of laying down is according to the controlled motorized valve aperture signal of gathering, adjust the aperture of weir plate, reach the purpose of the flooding quantity of regulating sewage disposal series, avoid the water yield to exceed the normal processing water yield, make and handle serial aeration deficiency, microorganism active is not high, the effluent quality variation; Prevent that also the water yield is lower than the normal processing water yield, make and handle serial aeration surplus that the microorganism endogenous respiration not only wastes energy but also make process result degrades.Each sewage disposal series of sewage work all can be installed the weir-adjustable control device of a cover this patent, and many cover controls can also be provided with master controller between putting, and many covers control device is carried out harmony control.
Device of the present utility model has the following advantages: can avoid or reduce flooding quantity and change the detrimentally affect that wastewater treatment efficiency is caused; having solved the water yield distributes uneven and aeration surplus or insufficient contradiction; each handles the processing effect of series to have given full play to sewage work; reduce the Sewage Plant power consumption, improved treatment effect.Structure is perfect, and the investment working cost is few, save energy, and environmental influence is little, and control is flexibly, and is easy and simple to handle, and the level of automation height has improved the operational efficiency and the operating safety of sewage disposal device greatly.
