Abstract
The present invention relates to a rotary disk type aeration equipment for making biologicl treatment of sewage. Said invention is composed of two semi-disk bodies and disk shaft core, and is characterized by that on the disk body the trapezoidal oblique pyramidal projected small blocks are regularly densely arranged in the form of radiation, and between all the rows of trapezoidal small blocks there are lots of circular small pits, and the top surface of every trapezoidal small block has a small circular pit. Said invention can be matched with submerged baffler placed in the oxidation channel for use, so that it can change vertical distribution of flow rate of small flow, and the water depth of oxidation channel can be raised to 5.0 m from 3.0 m so as to raise oxygen transfer efficiency.
Description
Technical field
The present invention relates to a kind of aerator that sewage is carried out biochemical treatment, especially a kind of rotating disc type aeration in sewage treatment device.
Background technology
The aerator of prior art most surface aerating machine of falling the umbrella shape or aeration rotary brushs of adopting, this just makes that the oxidation ditch floor space is bigger, the degree of depth of oxidation ditch generally can only be at 3.0-3.5 rice.Make applying of oxidation ditch process be subjected to certain restriction.
Summary of the invention
Technical problem to be solved by this invention provides a kind of rotating disc type aeration in sewage treatment device, and it is simple in structure, and being used for oxidation ditch process saving energy, horizontal thrust, to reach oxygenation capacity greatly big.
The technical solution adopted for the present invention to solve the technical problems is: this aeration disk is made up of two semicircle disk bodies and disc axis, and disk body is provided with strengthening rib.Strengthening rib is asked and is provided with the breach that alleviates deadweight.It is characterized in that: on disc, be radial gathering regularly and arrange trapezoidal oblique prism cone raised nubs, each arrange be provided with between the trapezoidal fritter a large amount of circular little recessed, the optimum size that the end face of trapezoidal fritter is provided with recessed, the described trapezoidal oblique prism cone fritter of roundlet is: the 24*20 millimeter, the circular little recessed degree of depth is the 3-6 millimeter.The principle of work of rotating disc type aeration in sewage treatment device of the present invention is, during the aeration turn plate rotation, before the trapezoidal oblique prism cone protruding block of main dependence promotes current direction, simultaneously bigcatkin willow is gone out the water surface and form liquid film, the globule contacts with atmosphere airborne oxygen is dissolved in the water.All circular little air in recessed simultaneously, also that it is contained oxygen is transferred to and makes it oxygenation in the water: be arranged on the recessed increase of roundlet on the trapezoidal small lugs end face liquid film that pumps up water, the dissolved oxygen of the globule.
The invention has the beneficial effects as follows: because disk diameter is big, trapezoidal oblique prism cone raised nubs construction size is different with existing rotating disk, flood the supporting use of flow deflector in the oxidation ditch with being arranged on, can change the vertical distribution of flow rate of water flow, thereby raising that can be bigger just can be brought up to 5.0 meters by 3.0 meters with the depth of water of oxidation ditch to the thrust of water; Improve the depth of water and can save occupation of land and construction costs, also enlarged the use range of oxidation ditch simultaneously: because the circular little recessed general big degree of depth of rotating disk that adopted, it is recessed to have set up roundlet at trapezoidal small lugs end face especially again, improved oxygen transfer efficiency, no matter be the oxygenation capacity of single disc, or oxygen-transfer efficiency (unit of electrical energy oxygenation capacity) has all surpassed external advanced like product.

Fig. 1 is the structure iron of rotating disc type aeration in sewage treatment device.
Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment
As shown in the figure, a kind of rotating disc type aeration in sewage treatment device, form by two semicircle disk bodies 1 and disc axis 2, disk body is provided with strengthening rib 3, strengthening rib is asked and is provided with the breach 4 that alleviates deadweight, it is characterized in that: be the radial trapezoidal oblique prism cone raised nubs 5 of gather arranging regularly on disc, each is arranged and is provided with a large amount of circular little recessedly 6 between the trapezoidal fritter, and the end face of trapezoidal fritter is provided with roundlet recessed 7.Described trapezoidal oblique prism cone raised nubs is of a size of: the 24*20 millimeter, the circular little recessed degree of depth is 4 millimeters.
Claims (2)
1. rotating disc type aeration in sewage treatment device, form by two semicircle disk bodies (1) and disc axis (2), disk body is provided with strengthening rib (3), be provided with the breach (4) that alleviates deadweight between strengthening rib (3), it is characterized in that: on disc, be radial gathering regularly and arrange trapezoidal oblique prism cone raised nubs (5), each is arranged and is provided with a large amount of circular little recessed (6) between the trapezoidal fritter, and the end face of trapezoidal oblique prism cone fritter is provided with roundlet recessed (7).
2. rotating disc type aeration in sewage treatment device as claimed in claim 1 is characterized in that: the optimum size of described trapezoidal oblique prism cone raised nubs (5) is: the 24*20 millimeter, the degree of depth of circular little recessed (6) is the 3-6 millimeter.
