Abstract
The utility model discloses a sewage treating device composed of an oxygenizing hook, a propeller, an exposer and a blower, wherein the middle of the oxygenizing hook is provided with a baffle plate which partitions the oxygenizing hook into an annular groove in which the propeller is arranged and the exposer is arranged on the bottom surface of the annular groove and is connected with the blower arranged outside the oxygenizing hook through a pipeline. The utility model can also make the flow velocity of water flows in a ditch be more than 0.3 meters/ second so as to prolong the staying time of small air bubbles in the ditch, and achieves the purposes of high exposing and oxygenation efficiency and high energy saving through the respective control of the propeller and the blower.
Description
The utility model relates to a kind of waste disposal plant.
At present fairly obvious to the effect of sewage disposal with oxidation ditch, it has the dual function of hybrid fully and pulling flow type, being provided with in the oxidation ditch must make the sewage in the ditch can finish aeration process and keep the flow process, make the interior aerobic microbiological of ditch breathe oxygen and come organic pollutant in the degradation water, thereby sewage is purified.Present oxidation ditch all adopts the wherein a kind of machinery that changes brush, plate-spinning and inversed umbrella type aerator to finish oxygenic aeration simultaneously and promotes flow in the ditch, these aerators are forced airborne oxygen is imported in from the water surface toward water, since on the direction air be with top to bottm deeply water-bed, produced air and be difficult to penetrate into form dissolved oxygen in the water, more be difficult to penetrate into the bottom, simultaneously, the air that has infiltrated is because the proportion effect, the very fast water surface of emerging in the water again.All adopt the machinery of these surface aeration type formulas both at home and abroad, but change brush, the use of plate-spinning and inversed umbrella type aeration machinery, use same machinery to finish aeration and promotion flow action simultaneously, make the flow velocity in the ditch must keep the above flow velocity of 0.3 meter per second, aeration is finished simultaneously, when the dissolving in the water acquires a certain degree, this machinery also must keep starting in order to keep flow rate of water flow, the table power efficiency of oxygen supply that exposes to the sun is low and wayward during this process, aspect only needing to promote current and when not needing the process of oxygenic aeration, cause energy dissipation, the dark master of oxidation ditch is restricted.
The purpose of this utility model is to provide a kind of table expose to the sun oxygen-transfer efficiency height, energy-conservation big waste disposal plant.
For achieving the above object, waste disposal plant of the present utility model is made up of oxidation ditch, thruster, exposure unit, gas blower, dividing plate is arranged in the middle of the oxidation hook, the oxidation hook is separated into ring groove, be provided with thruster in this ring groove, on the ring groove bottom surface aerator is set, aerator is connected by the pipeline gas blower outer with being located at oxidation ditch.
After adopting such structure, owing to be provided with thruster in the oxidation ditch, the interior flow velocity of ditch is guaranteed more than 0.3 meter per second, and gas blower is guided to air on the aerator of bottom of trench by pipeline, air occurs with tiny bubble, bubble and water are increased duration of contact, increased dissolved oxygen, shown to expose to the sun oxygen-transfer efficiency height, thruster thereby reach, gas blower is the mode of controlling respectively, and energy loss is greatly reduced.
Fig. 1 is the structural representation of a kind of embodiment of the present utility model.
Waste disposal plant as shown in Figure 1, form by oxidation ditch 8, thruster 2, exposure unit 3, gas blower 6, there is dividing plate the centre of oxidation hook 8, oxidation hook 8 is separated into ring groove, in this ring groove, be provided with 4 thrusters 2, be arranged in the turning of ring groove respectively, be provided with aerator 3 on oxidation ditch 8 ring groove bottom surfaces, aerator 3 is connected by pipeline 5 gas blower 6 outer with being located at oxidation ditch.During work, sewage enters in the oxidation ditch 8 from water inlet pipe 1, by thruster 2 promotion current under water, keep current to flow 0.3 meter per second to keep microorganism and the sewage thorough mixing in the ditch, prevent that sludgd deposition from producing the heavy phenomenon of anaerobism and accelerating organic pollutant in the sewage and the reaction of microorganism, the required oxygen of aerobic microbiological is then imported bottoms of trench by gas blower 6 by pipeline 5, from bottom to top discharge from bottom of trench with micro-bubble by micro-hole aerator 3 again, increased the residence time that gas ducks in drink, sewage has been purified by above-mentioned process.
Claims (2)
1, a kind of waste disposal plant, form by oxidation ditch (8), thruster (2), exposure unit (3), gas blower (6), dividing plate is arranged in the middle of the oxidation hook (8), oxidation hook (8) is separated into ring groove, it is characterized in that: be provided with thruster (2) in this ring groove, aerator (3) is set on the ring groove bottom surface, and aerator (3) is connected by pipeline (5) gas blower (6) outer with being located at oxidation ditch.
