Abstract
The utility model discloses a secondary jet mixing aerator, comprising a water pump (3), a Venturi ejector (4), a water pipe (5) and a waterpower nozzle (7), wherein the conduit of the water pump (3) is connected with the Venturi ejector (4) which is connected with the waterpower nozzle (7) with different installation angles through the water pipe (5), and the gas is sucked from the suction inlet (6) of the Venturi ejector. The utility mode has the advantages of high transfer efficiency and not easy blockage; the utility model improves the utilization ratio of the oxygen and guarantees the dissolved oxygen density needed in mixture liquid, the push-flow effect is good, and the cost is low. The utility model is suitable to oxygenate for manual lake, lake and river, which have wide water surfaces.
Description
Technical field
The utility model relates to technical field of sewage, especially relates to a kind of secondary jet mixed aeration device that is applicable to that the traditional active sludge treatment process uses.
Background technology
Utilize bioremediation to remove and in the sewage polar contaminants matter arranged, so far still be acknowledged as most economical processing mode, be widely used in technical field of sewage, wherein active sludge treatment program (activated sludge treatment process) and various deutero-treatment process thereof, no matter be in city domestic sewage or industrial waste water treatment system, all occupy high application percentage.Active sludge treatment process can adopt the air aeration technology, also can adopt the pure oxygen aeration technology, in order to keep the necessary dissolved oxygen concentration of biological treatment in the aeration tank, how oxygen effectively is delivered in the sewage and with the sewage thorough mixing be a known difficult problem, in the prior art, various aerators are exactly to be specifically designed to the device that solves this difficult problem; But all exist transfer efficiency low, stop up and the bad shortcoming of plug-flow effect easily.
Summary of the invention
Goal of the invention of the present utility model is to overcome above-mentioned prior art defective, a kind of transfer efficiency height is provided, is not easy to stop up and plug-flow is effective, cost is low secondary jet mixed aeration device.
In order to achieve the above object, the utility model adopts following technical scheme: a kind of secondary jet mixed aeration device comprises water pump, Venturi ejector, water pipe, hydrojet nozzle; Water pump water delivery water channel connects the Venturi ejector, and the Venturi ejector connects hydrojet nozzle by water pipe, and gas sucks from the suction port of Venturi ejector.
Be connected with the hydrojet nozzle of several different setting angles on the described water pipe.
Described hydrojet nozzle sprays in the pond, pond from the bottom up with different angles.
Described hydrojet nozzle sprays in the pond, pond from top to bottom with different angles.
Described water pump, Venturi ejector can be positioned at outside the pond, also can be positioned at the pond, and Venturi ejector water pipe connecting stretches in the pond.
Compared with prior art, the secondary jet mixed aeration device that provides of the utility model has the following advantages:
1, transfer efficiency height, oxygen dissolution are fully and be not easy to stop up: because oxygen mixes for twice with liquid Venturi ejector and hydrojet pipe, oxygen is blended in the treatment solution fully, improved the utilization ratio of oxygen, guaranteed needed dissolved oxygen concentration in the mixed solution, the big 50-1000 cubic meter/h of secondary jet mixed aeration device amount of jet, oxygen transfer efficiency height can reach 4.27-5.36kg/kw.h.
2, plug-flow is effective: the big 50-1000 cubic meter/h of secondary jet mixed aeration device amount of jet, plug-flow is effective.
3, the utility model does not have guide shell, thereby has reduced cost, and is more suitable for wide man-made lake of the water surface or oxygenations such as lake and river course.
