Abstract
The utility model belongs to an aeration device for sewage biochemical treatment. An existing aeration device is low in aeration efficiency and large in noise and adversely affects the environment. The aeration device for the sewage biochemical treatment comprises a liquid main pipe and is characterized in that a plurality of reducing pipes communicated with the inside of the liquid main pipe are arranged outside the liquid main pipe. The caliber of the outlet end of each reducing pipe is smaller than that of the inlet end connected into liquid main pipe, and the reducing pipes are respectively communicated with a plurality of gas-liquid mixing chambers arranged outside the liquid main pipe. The upper portion of the liquid main pipe is provided with a gas guiding main pipe which is connected into the gas-liquid mixing chambers through branch gas pipes. The aeration device for the sewage biochemical treatment enables air and sewage to be fully mixed and discharged into a sewage pool, thereby improving effect of the biochemical treatment. Pollutants can be refined to prevent pollutants from solidifying. The noise is small and does not affect the environment.
Description
Technical field
The utility model belongs to the environmental protection equipment field, especially a kind of sewage biochemical treatment aerator that is used for.
Background technology
Aeration is meant artificial through suitable equipment bubbling air in biochemical aeration tank, to reach its intended purposes.Aeration not only makes in the pond liquid-to-air contact oxygenation, and because agitated liquid, has quickened that oxygen shifts in liquid in the air, thereby accomplishes the purpose of oxygenation; In addition, aeration prevents that in addition pond inner suspension body from sinking, and strengthen the purpose that organism and mikrobe contact with dissolved oxygen in the pond, thereby in the assurance pond there is being under the condition of sufficient dissolved oxygen mikrobe, to organic oxygenolysis in the sewage.The quality of aerating apparatus not only influences sewage biochemical treatment effect, and directly has influence on a processing occupation of land, investment and working cost.Existing aerating apparatus mainly is in sewage lagoon, to place aeration tube, utilizes gas blower that air is thrown in the pond through aeration tube again, makes to contain oxygen in the sewage lagoon; And there is following problem in this type aerating apparatus: 1. because air is to utilize a large amount of the throwing in the sewage lagoon of gas blower; Though the air total amount is many, volume is also relatively large, so have only the surface to contact with sewage easily; And most of air is dissipated in the air, so its aeration efficient of traditional aerating apparatus is lower.2. because the gas blower operation noise is big, environment is impacted, gas blower when work thermal value is big, if meet idle running or dispel the heat when bad, easily gas blower is burnt out, and causes damage.
The utility model content
The utility model provides a kind of sewage biochemical treatment aerator to the defective that prior art exists, and effectively the oxygen level in the lifting sewage improves the biochemical treatment effect, and noise is little, can not impact environment.
For this reason; The utility model is taked following technical scheme: a kind of sewage biochemical treatment aerator; Comprise the liquid house steward; It is characterized in that a plurality of constriction pipes that communicate with the liquid manifold of the outer configuration of described liquid house steward, the exit end bore of this constriction pipe is less than the inlet end bore that inserts the liquid house steward, and outside with the being arranged on the liquid house steward respectively again a plurality of gas-liquid mixed chamber of described constriction pipe communicates; Said liquid house steward's top is provided with an air guide house steward, and it is indoor that described air guide house steward inserts gas-liquid mixed through segmental bronchus.It is indoor that liquid is injected into gas-liquid mixed through the constriction pipe, and the air in the air guide house steward is synchronized through segmental bronchus again that to be delivered to gas-liquid mixed indoor, makes air and liquid at the indoor thorough mixing of gas-liquid mixed; Can effectively reduce the size of bubble, and increase bubble quantity and bubble, improve the turbulent extent of liquid; Change " solution-air " interface fast, effectively overcome liquid-film resistance, greatly improved the concentration of dissolved oxygen; And reduced power consumption, had good energy-saving effect; It is more even that solid microbe is suspended, and improved the biochemical treatment effect.
As preferably, the exit end bore of said gas-liquid mixed chamber is less than the circulation passage bore of gas-liquid mixed chamber.The nozzle structure of constriction pipe and gas-liquid mixing section helps improving the projection velocity of liquid, prevents line clogging, has realized that stable, LP effectively moves.
As preferably, the handing-over mouth of described segmental bronchus and gas-liquid mixed chamber is positioned at the outside of constriction pipe, makes the gas-liquid thorough mixing.
As preferably, it is indoor that described constriction pipe inserts gas-liquid mixed, guarantees the gas-liquid thorough mixing.
As preferably, many group gas-liquid mixed chambers are set on said liquid house steward's the length direction, every group is two and is symmetricly set on liquid house steward's both sides, promotes gas-liquid mixed efficient.
As preferably, the angle between two said every group gas-liquid mixed chambers is 120 °.
As preferably, said gas-liquid mixed chamber direction is set for tilting down, can fast mixed solution be entered sewage lagoon to handle, possess energy-saving effect.
As preferably, described segmental bronchus is a bend pipe.
The utility model has been set up the gas-liquid mixed chamber and to the indoor air guide house steward who fills air of gas-liquid mixed outside traditional sewage pipe, enter sewage lagoon again after making air and sewage thorough mixing, has improved the biochemical treatment effect.The structure of constriction pipe and gas-liquid mixed chamber can effectively promote liquid jeting speed, cut down the consumption of energy, and blocky dirt is through also can be broken behind the gas-liquid mixed chamber, can the refinement dirt, prevent that dirt from solidifying.
