Abstract
A perforated aerator pipe applied to sewage water biochemical treatment comprises a perforated aerator pipe. A plurality of isometric circular penetration holes are formed on a straight line on the wall of the perforated aerator pipe in the length direction thereof; the diameter of each circular penetration hole ranges from 6 to 9 mm; the perforated aerator pipe is mounted in a sewage treatment pool through a fixing bracket; when the perforated aerator pipe is installed, the height from the center of the perforated aerator pipe to the bottom of the sewage treatment pool remains from 200 to 300 mm; the circular penetration holes of the perforated aerator pipe are positioned vertically downwards; and after coming out of the circular penetration holes, gas is reflected by the bottom of the sewage treatment pool to be aerated, so that bubbles are small in volume and large in quality and can be utilized by microorganisms to degrade contamination in water. Compared with the prior art, the diameters of the circular penetration holes are larger so that the circular penetration holes have little possibility of being blocked; and moreover, the utility model has the advantages of high oxygen utilization efficiency, lower energy consumption, convenient installation and overhauls, simple structure, low manufacturing cost and long service life.
Description
Technical field
The utility model relates to a kind of boring aeration pipe that is applied to the sewage biochemical treatment.Belong to technical field of sewage treatment equipment.
Background technology
In the biochemical treatment process of sewage, in order to keep the vital movement of microorganism in the sewage, must guarantee has a certain amount of dissolved oxygen in the sewage.Keep in order to ensure microbial life active in the treatment tank, usually adopt aerator oxygen supply in sewage.Aerator in the prior art mainly contains two kinds of micro-hole aerator and boring aeration pipes, though micro-hole aerator has higher dissolved oxygen efficiency, the production cost height simultaneously because its aperture is very little, thereby easily stops up, and work-ing life is short, installation and maintenance are inconvenient; Boring aeration pipe is directly perforate on plastic conduit, allow gas from the hole, discharge, and boring aeration pipe commonly used at present is that double circular perforations is set on plastics tubing, piercing aperture is below 5mm, be 45 ° at the bottom of gas release direction and the pond, though this method is very easy, manufacturing cost is also cheaper, work-ing life is also longer, but outstanding shortcoming is that dissolved oxygen efficiency is not high.
The utility model content
The purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of boring aeration pipe that is applied to the sewage biochemical treatment that provides.
A kind of boring aeration pipe that is applied to the sewage biochemical treatment of the present utility model is achieved through the following technical solutions:
A kind of boring aeration pipe that is applied to the sewage biochemical treatment comprises boring aeration pipe, and several isometrical circular perforations evenly are set on the wall of described boring aeration pipe, on any straight line of its length direction.Described boring aeration pipe can be that plastics tubing or other can the rot-resistant material be manufactured and formed.
And the diameter of described circular perforations is 6～9mm.
A kind of boring aeration pipe that is applied to the sewage biochemical treatment of the present utility model has following advantage with respect to prior art:
1, circular perforations diameter of the present utility model is bigger than of the prior art, is 6～9mm, thereby is difficult for stopping up;
When 2, the utility model was installed, the aperture of circular perforations made that the gas distribution of treatment tank is even vertically downward, has improved the utilization ratio of oxygen greatly, has reduced energy consumption;
3, the utility model is installed, overhauled conveniently, and is simple in structure, cheap, long service life.
Description of drawings
Fig. 1 is a kind of boring aeration pipe orthographic plan that is applied to the sewage biochemical treatment of the present utility model;
Fig. 2 is a kind of boring aeration pipe installation plan that is applied to the sewage biochemical treatment of the present utility model.
Embodiment
For can being known, one of ordinary skill in the art understands the technical solution of the utility model, the further explanation at large of existing do in conjunction with the accompanying drawings.
A kind of boring aeration pipe that is applied to the sewage biochemical treatment, as shown in Figures 1 and 2, comprise boring aeration pipe 1, several isometrical circular perforations 2 evenly are set on the wall of boring aeration pipe 1, on any straight line of its length direction, the diameter of circular perforations 2 is 6～9mm.
Mounting means:
As shown in Figure 2, boring aeration pipe 1 is installed in the treatment tank by fixed support 3, during installation, 4 height H are decided according to selected fixed support form at the bottom of the boring aeration pipe 1 tube center distance treatment tank pond, are generally 200～300mm.With the circular perforations 2 of boring aeration pipe 1 vertically downward, the end of boring aeration pipe 1 adopts plug 5 sealings (as shown in Figure 2), head end to be connected with aeration arm 7 by elbow 6.After gas came out from circular perforations 2,4 reflections at the bottom of the treatment tank pond and aeration makes bubble volume little and quantity helped being used to the water pollutant of degrading by microorganism.
Claims (2)
1, a kind of boring aeration pipe that is applied to the sewage biochemical treatment is characterized in that, comprises boring aeration pipe (1), and several circular perforations (2) evenly are set on the wall of described boring aeration pipe (1), on the straight line of its length direction.
2, a kind of boring aeration pipe that is applied to the sewage biochemical treatment according to claim 1 is characterized in that, the diameter of described circular perforations (2) is 6～9mm.
