Description
Technical field
The utility model relates to sewage treatment area, specifically discloses a kind of sewage disposal regulating reservoir.
Background technology
In sewage disposal, because the water quality of wastewater influent is complicated, water yield fluctuation is very large, draining is uneven, must arrange regulating reservoir and carry out pretreatment.Traditional regulating reservoir is generally square regulating reservoir, also has small part to be concentric circles regulating reservoir, and which kind of regulating reservoir all needs water distribution and stirring to combine, and just can reach better regulating effect.
Stirring is the vital link of sewage disinfection treatment.Conventional stirring means has water pump forced circulation, air stirring, mechanical agitation, perforation guiding gutter diversion four kinds of methods.Adopt water pump forced circulation and air stirring, excessive for power consumption the sewage containing high suspended matter; Adopting mechanical agitation, there is adjustment dead angle in the corner restriction of traditional square regulating reservoir; Adopt perforation guiding gutter diversion mode, although can get rid of above-mentioned shortcoming, regulating effect is stable not, and structure structure is complicated, and particularly the problem of spoil disposal is comparatively difficult to resolve certainly, also lacks respond well structural form at present.
In order to solve the problem of stirring, the research both at home and abroad for regulating reservoir mainly adopts following two schemes: (1) additionaling power regulating reservoir.The equipment such as the additional impeller stirring of main employing, blast air stirring or water pump circulation carry out forced adjustment to water quality.(2) stream mode regulating reservoir is differed from: the regulating reservoir comprising two types, i.e. diagonal regulating reservoir and concentric circles regulating reservoir.The feature of diagonal regulating reservoir is that effluent trough is diagonally arranged, sewage enters in pond by the left and right sides, flow to effluent trough through the different time, thus make successively to enter the waste water of regulating reservoir and the waste water mixing of variable concentrations, reach automatically regulate all and object.Concentric circles regulating reservoir arranges many baffling partition walls in pond, controls sewage 1/3 ~ 1/4 flow and flows into from the origin or beginning of regulating reservoir, carry out diffraction current, time delay, abundant mixed equilibrium in pond; Remaining flow drops into each position before and after in pond equally by each dosing mouth being located at the distribution channel on regulating reservoir.
This two classes regulating reservoir cuts both ways.The mode equipment of additionaling power regulating reservoir is simple, and operational effect is good, but operating cost is higher.Difference stream mode regulating reservoir can make the sewage of different time and variable concentrations carry out the mixing of water quality self waterpower, and rely on the displacement of current, there is no operating cost, but pond body structure is more complicated, spoil disposal problem cannot solve always.This two classes regulating reservoir all defectiveness, the pretreatment especially for high suspended matter high-concentration sewage does not all reach desirable effect, therefore needs one more rationally effective sewage disinfection treatment regulating reservoir.
Summary of the invention
For problems of the prior art, the purpose of this utility model is to provide a kind of sewage disposal regulating reservoir.This regulating reservoir is particularly useful for the pretreatment of high suspended matter high-concentration sewage, water quality adjustment effect stability, and structure structure is simple, and equipment energy consumption is low, and can solve sludgd deposition problem.
In order to achieve the above object, the utility model is achieved by the following technical solutions.
A kind of sewage disposal regulating reservoir, it is characterized in that, comprise circular pond body, the bottom centre of pond body is to being arranged with catch pit, the periphery of catch pit is arranged at intervals with the arc training wall with pond body concentric, and the two ends of arc training wall are provided with radial guiding stream wall in pond in direction, the body center of circle, reverse pond respectively; The inwall of described pond body is arranged at intervals with the radial training wall of the pool wall pointing to direction, the body center of circle, pond, and the interval of the arc training wall that the radial training wall of each pool wall is adjacent with two is relative; The center of described arc training wall is provided with the distribution channel in direction, the body center of circle, reverse pond, is provided with water conservancy diversion flap immediately below distribution channel; The center of described pond body is provided with agitator, and the sidewall of catch pit is provided with water pump suction pipe.
Feature of the present utility model and further improvement are:
Described catch pit is slope aspect catch pit.
Described distribution channel is perforation distribution channel.
In the radial training wall of described pool wall and described pond, the length of radial guiding stream wall is the 1/3-1/8 of the diameter of described pond body.
Distance bottom described water conservancy diversion flap and described pond body is between 600-800mm.
Described agitator is Double-curved-surface stirring device.
Preferably, the diameter of described pond body is less than or equal to 30m, and footpath is deeply than between 6-10.
When utilizing the utility model to carry out sewage disinfection treatment, sewage enters regulating reservoir by distribution channel, first flows through water conservancy diversion flap, realizes from up to down, bottom-up upset under the effect of water conservancy diversion flap, plays immixture; Then flow through radial guiding stream wall and the radial training wall of pool wall in arc training wall, pond, under the effect of three road training walls, current mix mutually forward, flow into pool center.Under the effect of agitator, again mix sewage quality, last sewage enters catch pit, is taken away by water pump suction pipe.
Advantage of the present utility model and beneficial effect are: (1) this regulating reservoir solves Sludge in Sewage Treatment deposition and spoil disposal problem.Regulating reservoir is designed to circle, and streamflow regime can be made good, circumferential water feed central water outlet, water conservancy diversion combines with stirring, and to the equal of water quality and Be very effective, high concentration suspended matter cannot deposit, and thoroughly solves the problem of sludgd deposition and spoil disposal.This regulating reservoir structure has overturned the version of traditional regulating reservoir.Be particularly useful for the process engineering of high suspended matter, high-concentration sewage.(2) this regulating reservoir structure is simple, and rely on the displacement mixing of current, equipment energy consumption is low, water quality adjustment effect stability, can realize the application of large-scale industry.
