Abstract
The invention relates to a cylindrical underground spliced horizontal flow sedimentation tank. The cylindrical underground spliced horizontal flow sedimentation tank comprises a water inlet channel, a water pool, an inlet water overflow weir, a water distributing plate, an outlet water overflow weir, a mud collecting well and a water outlet channel, the water pool is formed by assembling and splicing cylindrical horizontal cylindrical shells, two ends are provided with end caps to form the water pool, the cylindrical mud collecting well is arranged below one side of the cylindrical water pool, and the contour of the water outlet overflow weir adopts a concave weir. The cylindrical underground spliced horizontal flow sedimentation tank has the advantages of scientific design fastened structure, superior corrosion resistance, strong durability, short production period, low making cost, energy saving, environmental protection, stable running, safety and reliability.
Description
Technical field
The invention belongs to sewage treatment process facility field, the buried splicing horizontal sedimentation tank of especially a kind of column type.
Background technology
Along with the economic develop rapidly of China, urbanization process is further accelerated, city size expanding day, and quantity of wastewater effluent rises rapidly, and municipal sewage treatment ability is had higher requirement.Within 2012, country has issued the national town sewage processing of < < " 12 " and regeneration Facilities Construction planning > >.During " 12 ", China will continue to advance the newly-built and existing Sewage Plant upgrading of sewage treatment plant.Rectangular sedimentation tank, because its sedimentation effect is good, is used more extensive.During " 12 ", horizontal sedimentation tank will be applied in some projects.Existing horizontal sedimentation tank generally adopts monolithic reinforced concrete structure.Monolithic reinforced concrete structure needs on-the-spot construction, long construction period, and floor space is large, and construction cost is high.
Summary of the invention
The object of the invention is to overcome the deficiency of pre-treating process for sewage facility in existing sewage disposal system, provide a kind of design science, firm in structure, antiseptic property is superior, durability is strong, with short production cycle, cost of manufacture is low, energy-conserving and environment-protective, stable, the safe and reliable buried splicing horizontal sedimentation tank of column type.
The present invention solves its technical problem and is achieved through the following technical solutions:
The buried splicing horizontal sedimentation tank of a kind of column type, by intake tunnel, pond, water inlet downflow weir, water distributing plate, effluent overflow weir water, mud-collecting well, exhalant canal, formed, pond is spliced by the assembling of column type horizontal cylinder, two ends make plug and form pond structure, in column type pond, one side-lower is arranged column type mud-collecting well, and effluent overflow weir water profile adopts spill weir.
And described pond adopts column type horizontal cylinder to connect by bell and spigot.
And, the spill weir that described effluent overflow weir water adopts crest of weir be shaped as triangle and trapezoidal.
And described column type mud-collecting well adopts the form of threeway to be packed under pond for collecting mud.
Advantage of the present invention and beneficial effect are:
1, the buried splicing horizontal sedimentation tank of this column type adopts prefabricated mode in factory to produce, and has shortened the cycle of site operation, and mature production technology is with short production cycle, and energy-conserving and environment-protective are stable, safe and reliable.
2, the buried splicing horizontal sedimentation tank of this column type adopts column type horizontal cylinder to connect by bell and spigot, and installation rate is fast, has improved efficiency of construction, has shortened construction period, has reduced construction cost.
3, the buried splicing horizontal sedimentation tank of this column type antiseptic property is superior, and durability is strong, is longer than other like products service life.
4, the buried splicing horizontal sedimentation tank of this column type is applied widely, can be used for the sewage disposal of the different qualities such as sanitary sewage, trade effluent, Hospital medical sewage.And adopt buried setting, save a large amount of aboveground spaces.
5, the buried splicing horizontal sedimentation tank of this column type can be made according to designing requirement the tank body of all size size, and at present general can body internal diameter is 3.6m to the maximum, also can manufacture the tank body that internal diameter is larger according to same process.
6, the buried splicing horizontal sedimentation tank water inlet of this column type is stable, and sedimentation effect is good, and effluent quality meets sewage disposal requirement, is applicable to the sewage disposal of different quality.

The specific embodiment
Below by specific embodiment, the invention will be further described, and following examples are descriptive, is not determinate, can not limit protection scope of the present invention with this.
The buried splicing horizontal sedimentation tank of a kind of column type, by intake tunnel, pond, water inlet downflow weir, water distributing plate, effluent overflow weir water, mud-collecting well, exhalant canal, formed, it is characterized in that: pond is spliced by the assembling of column type horizontal cylinder, two ends make plug and form pond structure, in column type pond, one side-lower is arranged column type mud-collecting well, and effluent overflow weir water profile adopts spill weir.Sedimentation basin adopts column type horizontal cylinder to connect by bell and spigot.The spill weir that effluent overflow weir water adopts crest of weir be shaped as triangle or trapezoidal.Column type mud-collecting well adopts the form of threeway to be packed under pond for collecting mud.
Operation principle of the present invention:
Sewage flows into sedimentation basin by intake tunnel 1, first through water inlet downflow weir 7, then by inflow pond, equally distributed inlet opening body on water distributing plate 8, makes current be evenly distributed in wide cross section, whole pond.Mud is deposited to bottom, pond under Action of Gravity Field, and mud scraper 9 use coordinate the arc cleaning shoe 11 of pond Bottom Shape the mud at the bottom of pond to be pushed to the sludge hopper 5 that is located at front portion, pond, are provided with discharge pipeline 2 in sludge hopper 6, carry out regular spoil disposal.Pond body 3 is column types, the precipitation of pond body 3 both sides is highly less than the precipitation height in the middle of the body of pond, therefore, the profile of effluent overflow weir water 10 adopts spill weir, make pond body intermediate sedimentation completely primary water flow out equably, it is middle after fully precipitating that the water of body both sides, pond is back to pond body again, then flow out through effluent overflow weir water 10.Primary water is flowed out by exhalant canal 5.At body rear portion, pond, be provided with manhole 4, in manhole, have cat ladder 12.
In Fig. 2, h0 is that pond top mark is high, and h1 is water inlet downflow weir absolute altitude, and h2 is effluent overflow weir water absolute altitude, h1 > h2.Sludge hopper 5 can need to be changed size according to operating mode.
In Fig. 5 and Fig. 6, the spill weir that effluent overflow weir water 10 adopts is triangle crest of weir 13 or trapezoidal crest of weir 14.
In Fig. 7, the connected mode of the buried splicing horizontal sedimentation tank of this column type is to adopt column type horizontal cylinder to connect by bell and spigot 15.
