Description
Technical field
The present invention relates to a kind of sewage disposal device, particularly a kind of aeration reactor.
Background technology
The aeration tank is to utilize activated sludge process to carry out the structures of sewage disposal.Certain dwell time of sewage is provided in the pond, satisfies the mixing condition that the needed oxygen amount of aerobic microbiological and sewage and active sludge fully contact.The aeration tank is mainly by pond body, aerating system and turnover
The mouth of a riverThree parts are formed.
Present aeration method mainly contains blast aeration and mechanical aeration, and the aeration tank is generally uncovered structure, problem such as aeration rate is bigger, and it is low that ubiquity the aeration dissolved oxygen amount, and the utilization ratio of oxygen is low.The direct influence that this situation is brought is exactly that energy consumption is excessive, and can increase for the operation cost of the required input of general sewage work thereupon.Face nowadays more and more higher electricity charge problem, can be directly strengthen the fund input of wastewater treatment, cause enterprise can't bear the waste water treatment engineering expense at all, or and close, or and the row of stealing omits contaminate environment in printing.
Therefore it is big low, the required oxygen amount of exposing to the sun of aeration dissolved oxygen amount (DO) at present domestic aeration tank ubiquity, air duct, pump and power of fan require problems such as height and easy damaged, and a kind of novel aeration dissolved oxygen amount height of design studies, the aeration reactor that energy consumption is low are imperative.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of aeration dissolved oxygen amount height, aeration reactor that energy consumption is low.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of closed aeration reactor, mainly comprise reactor, and its innovative point is: described reactor is closed pond body structure, and the pond body is water-in along long axis direction one end, and the other end is water outlet; The pond body is provided with the chemical feed pipe of emptying valve and band valve; The sidewall of pond body is distributed with some aerating pores, and described aerating pore is positioned at the pond body sidewall, and the airintake direction of aerating pore is vertical with pond long axis of body direction; The built-in floating stuffing of pond body.
Further, establish the pulse water distribution device at water-in.
Further, described emptying valve is near the water outlet oral-lateral.
Further, described chemical feed pipe is near the water inlet oral-lateral.
Further, the relative density of described floating stuffing and water is 0.8-1.0.
Further, described aerating pore adopts air blast or jetting type aerating apparatus, and aerating apparatus is installed on the body sidewall of pond, and the aeration head of aerating apparatus inserts in the body of pond by welding or adhesive structure at the aerating pore place.
Further, the air flow line of described aeration head is for being the inscribed circle tangential direction setting in axle center with the pond long axis of body.
The invention has the advantages that: utilize closed pond body structure, by the device band is pressed, the dissolved oxygen amount in the increase processing water and the residence time of oxygen, the utilising efficiency of dissolved oxygen in the raising device is to reach energy-conservation, the purpose of increasing economic efficiency in the aeration tank.Selection is to microorganism toxicological harmless, easy to be filmed, light weight, high strength, anti-aging, the filler of conditions such as the big and porosity height of specific surface area, control filler relative density is about 0.8-1.0, filling ratio can reach about 90 percent, and during operation, floating stuffing evenly distributes in the pond, and constantly Cutting Gas is steeped, coefficient of oxygen utilization is improved, and dynamic efficiency improves, and can obviously improve the clearance of COD in the sewage.Convenient for maintenance is installed, filler can be caught with net and be filled in the pond.
Establish the pulse water distribution device at water-in, when water inlet, make it form stream of pulses directive filler, as filler and O
2Fully contact reacts improves organic removal rate; The control air-flow enters from the reactor wall tangential direction, can drive the rotation of water body, and water is fully mixed with oxygen, further promotes the aeration effect.
Consider that sewage enters the back from an end and forms eddy flow, continuously eddy flow is near water outlet, and the emptying valve of pond body is located near the water outlet, is used for discharging gas, explodes in order to avoid reactor pressure is excessive.Being provided with chemical feed pipe near the water-in, is to add medicament and other material in the pond when being convenient to concrete engineering construction.
Aeration tank of the present invention can cooperate the employing tapered aeration, to save energy consumption, improves processing efficiency, when being applied to concrete engineering, should be on sidewall of reactor even gas distribution, control air inlet by the control inlet mouth, thereby determine best aeration rate.
