Abstract
The utility model relates to an overflow sewage intercepting well in the environmental protection field, in particular to a cone control intercepting well with equivalent intercepting sewage flow, wherein the intercepting sewage flow is controlled by liquid level height. When the inflow is larger, mixed water containing rainwater and sewage after dilution can much enter an intercept sewer, thus sewage in a water storage pond of a sewage treatment plant can be further diluted, due to limited treatment capacity, spare parts are discharged into a water body without treatment, the sewage remained in the water storage pond of the sewage treatment plant is diluted, the contents of pollutants are lowered, and since carbon is needed to be additionally added during treatment, the treatment cost is increased, and the maximum sewage intercepting function is not realized. The utility model aims to overcome the defects of the prior art and disclose the intercepting well which has a reasonable and novel structure, and can well realize equivalent intercepting sewage flow. The problem that under the condition that the treatment and storage capacities of the existing sewage treatment plant and the storage capacities of the intercepting well and a pipe network are unchanged, the sewage in the water storage pond of the sewage treatment plant is further diluted by a way that the mixed water containing the rainwater and the sewage after dilution much more entering the intercept sewer is reduced is solved, and the maximum interception of pollutants in intercepting river basin can be realized.

Technical field
The utility model relates to a kind of environmental protection field overflow-type sewage catchpit, relates in particular to a kind of amount of damming catchpits such as cone control by the liquid surface height controlling amount of damming.
Background technology
In existing urban sewage discharge system, usually there are three kinds of sewage network situations, combined system sewage network, segregation system sewage network and mixed flow system sewage network, the segregation system sewage network is generally adopted in the born city, and the combined system sewage network is still continued to use in mature city or old town.When drought flowed, the sewage of combined system sewage network all entered Wastewater Treatment Plant, but when raining, because the disposal ability of Wastewater Treatment Plant is limited, some combined sewage will enter water body, thereby influences water body environment.Catchpit commonly used now has three kinds of forms: great-jump-forward catchpit, weir formula catchpit and slot type catchpit.Great-jump-forward catchpit and slot type catchpit have a common shortcoming: when coming the water yield big, just overflow may occur when instantaneous, the effect that stops effluent stream is very undesirable.Though weir formula catchpit can overcome this shortcoming, but when big and duration of rainfall is longer when rainy, section dirty effect of weir formula catchpit is poor, its overflows to water body after can the rainwater that bigger rainwater of pollutant in early stage and later stage pollutant is less mixing, rising along with water level, pressure increases, the dirty mixing water of rain after the dilution can enter intercepting sewer more, thereby the sewage of the reservoir of further dilute sewage treatment plant, because disposal ability is limited, the unprocessed water body that just enters of redundance, the sewage of staying Wastewater Treatment Plant's reservoir is diluted, and pollutant load descends, and also wants the volume external carbon during processing, increased processing cost, do not played and cut dirty effect to greatest extent.
Along with the pay attention to day by day of the whole world to environmental protection, countries in the world, various places government continue to increase cut dirt, shunting and the transformation dynamics of the dirty interflow of town and country rain pipeline.Realize that the ideal of the dirty interflow of rain pipeline cuts dirt, just must reasonably transform, hold back the function of pollutant to greatest extent with the realization basin of damming to the structure of existing catchpit.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of prior art, discloses a kind of rational in infrastructurely, can realize waiting the catchpit of the novel structure of interception well.
The utility model is to address the above problem the technical scheme of being taked to be:
The amount of damming catchpits such as a kind of cone control, comprise, inner hollow and have a constant volume, profile is the well body of square or cuboid, at least 1 dirty mixed flow import of rain is a collecting fitting on the well body wall, the dam intercepting sewer of sewage, weir and bleed off pipe dam; It is characterized in that cone device with floatage control device.
The cone device is made up of Taper Pipe and inner cone, and the left end of Taper Pipe is connected with intercepting sewer, and inner cone is positioned at Taper Pipe, and is coaxial with Taper Pipe, between both surfaces certain interval arranged, and the right-hand member of inner cone is fixedlyed connected with slide bar.
Floatage control device is made up of slide bar, sliding sleeve, slide block, rocking bar, pull bar, lever and ball float, the left end of slide bar is fixedlyed connected with inner cone, and right-hand member and slide block are hinged, and the centre is positioned at, sliding sleeve, sliding sleeve is fixedlyed connected with the well body, rocking bar is a knee, and union elbow place and well body are hinged, and vertical end partly is positioned at slide block, the other end and pull bar are hinged, the other end of pull bar and the mid portion of lever are hinged, and an end of lever is fixedlyed connected with ball float, and the other end and well body are hinged.
When drought stream or rainfall hour, the water surface is lower in the catchpit, ball float falls, the drive lever rotates counterclockwise, and the lever pushing pull bar moves downward, and pull bar promotes rocking bar and rotates counterclockwise, rocking bar drives slide block and moves right, slide block drives slide bar and moves right, and slide bar drives inner cone and moves right, and the gap between inner cone and the Taper Pipe is strengthened.But because this moment, the water surface was lower, the pressure of the sewage of the mouth of pipe that dams is less, and flow velocity is less, and flow is certain.And when rainfall was big, the water surface raise gradually in the catchpit, and ball float lifts, and drove inner cone to left movement, and the gap between inner cone and the Taper Pipe reduces.But because this moment, the water surface was higher, the pressure of the sewage of the mouth of pipe that dams is bigger, and flow velocity is bigger, and flow is also certain.If the size of each member in the floatage control device is rationally determined, just can make the distance of cone move left and right corresponding, thereby make the amount of damming of intercepting sewer constant, so be referred to as to wait the amount of damming catchpit with water surface elevation.
The utility model has the advantages that:
Solved under the constant situation of the processing of existing Wastewater Treatment Plant, storage capacity and catchpit, pipe network storage capacity, the dirty mixing water of rain that reduces after diluting enters intercepting sewer too much, the maximization that the basin pollutant dams thereby the effluent problem of the reservoir of further dilute sewage treatment plant, realization dam.
