The utility model aims at providing the middle feed-in and side discharge sedimentation basin which can effectively maintain the uniform flow speed of water stream as well as reduce head loss in a horizontal flow basin and can improve the sedimentation efficiency and the hydraulic load of the horizontal flow basin. The middle feed-in and side discharge sedimentation basin is integrally rectangulate and comprises a water inlet well, a water inlet distribution channel, a filthy mud channel, a water outlet channel and a mud scrapping and suction machine, wherein the water inlet well is positioned on the middle part of the distribution channel which gradually shrinks from the middle part to the cross sections on both ends, and the spacing distances between the middle part and water distribution holes on both ends are gradually reduced. The utility model is mainly used for processing sewage water.

Description

Enter the limit in a kind of and go out sedimentation basin
Technical field
The utility model relates to a kind of sedimentation basin, particularly relates to a kind of novel rectangular sedimentation basin, especially relate to a kind of novel rectangular and in advance the sedimentation basin that the limit goes out.
Background technology
The activated sludge waste water disposal facility is one of most important link in the municipal sewage treatment, and its main units is reaction tank and second pond.Utilize the density contrast between the solid, liquid phase, the mud that biological respinse produced and the mixture of water carry out mud-water separation in second pond, clear water is on the upper strata, sludge settling is to the bottom, the upper strata clear water is discharged sedimentation basin in the back that is up to state standards, the mud part of bottom refluxes, outside the excess sludge discharge system.Second pond plays a part clarification, concentrates and stores mud, undertaking the task of removing a large amount of suspensions in the former water, main equipment is absolutely necessary, account for about 30% of engineering overall investment, it often becomes whole activated sludge process " bottleneck " part, is determining the operation conditions of whole system.Second pond can be divided into rectangular sedimentation tank according to the difference of pool inner water flow path direction, three kinds of radical sedimentation basin and vertical sedimentation basins.Wherein radical sedimentation basin and vertical sedimentation basin are circular pond body, and hydraulic load is higher, and are difficult to arrange that space availability ratio is not high, and rectangular sedimentation tank is a rectangle, is easy to arrange, but hydraulic load is lower.Common horizontal sedimentation tank, cloth drainage facility water distribution is inhomogeneous, and utilization rate of tank volume is not high, generally has only about 70%, and hydraulic load is lower, and floor space is big.
The utility model content
The purpose of this utility model provides a kind of all even minimizing loss of flood peak of flow rate of water flow that can effectively keep in horizontal flow basin, improve among the deposition efficiency of horizontal sedimentation tank and hydraulic load a kind of and advance the sedimentation basin that the limit goes out.
The technical solution adopted in the utility model is: enter the limit in a kind of and go out sedimentation basin, integral body is rectangle, comprise inlet well, water inlet distributes canal, the mud canal, go out water channel and scraping and sucking machine, wherein the mud canal is positioned at one side of sedimentation basin, going out water channel is two, lay respectively at the both sides of the symmetry of sedimentation basin, one end of scraping and sucking machine is communicated with the mud canal and perpendicular to the limit at mud canal place, inlet well distributes canal to be communicated with perpendicular to whole sedimentation basin and with water inlet, water inlet distributes canal to comprise the distributing channel on the limit that is parallel to the water channel place, be parallel to the limit at water channel place and distributing channel be divided into the lattice plate of two parts symmetrical, wherein the bottom of sedimentation basin is stretched out and is fixed in the bottom of lattice plate from the bottom of distributing channel, be positioned at bottom the distributing channel and along isolated several distributing holes of distributing channel length direction, the both sides that are distributed in the lattice plate of distributing hole symmetry, vertically be fixed on the baffle plate two that is used for water (flow) direction is controlled to be horizontal flow that water control that distributing channel bottom is used for flowing out from distributing hole is made as the baffle plate one of vertical current and is fixed on lattice plate bottom, described inlet well is positioned at the middle part of distributing channel, section to two ends reduces distributing channel gradually from the middle part, and from the middle part to two ends distributing hole between spacing distance dwindle gradually.
The section of described distributing channel is a rectangle.
The utility model is by being provided with baffle plate one and baffle plate two, thereby make current become the precipitation that horizontal flow is easier to mud, the lattice plate be arranged so that current are more even, the mode of water inlet both sides water outlet effectively reduces Reynolds number in the middle of taking, make and form stable advection effect in the sedimentation basin, simultaneously the cloth drainage facility is improved, take distributing channel tapered cross-section and convergent distributing hole are made all even minimizing loss of flood peak of water distribution apart from the mode that combines, also be convenient to construction simultaneously.This sedimentation basin can significantly improve sedimentation effect, increases surface loading, can reach 34m 3/ (m 2D), volumetric loading is higher than 5m 3/ m 2D, capacity utilization reach more than 85%, are better than general horizontal sedimentation tank more than 20%.
From architectural feature of the present utility model as can be seen, advantage of the present utility model is to make the more all even minimizing loss of flood peak of water distribution of sedimentation basin, thereby makes that the sedimentation effect of mud is desirable more in the processing procedure of sewage, significantly improves sedimentation effect.
