Abstract
The utility model provides a sewage treatment defoaming device which comprises a water pumping device arranged in a sedimentation tank, and a water delivery pipe network that is connected with the water pumping device and is arranged on the water surface of an aeration tank; two ends of the water delivery pipe network are respectively provided with a water inlet point; and the water inlet points are respectively connected with the water pumping device. The sewage treatment defoaming device adopts the water in the sedimentation tank in a sewage disposal system so as to be lower in cost, and enables the water to inflow from two sides of the aeration tank at the same time so as to effectively balance the water quantity and ensure the water to be uniform and stable.
Description
Technical field
The utility model relates to sewage treatment area, is specifically related to the defoaming device in the sewage disposal.
Background technology
In conventional sewage treatment process, the problem that often runs into is exactly a foamed phenomenon serious in the aeration tank, and is especially more common in the treating processes of trade effluent.Producing the foamy reason has in the water organic content too high, the organic composition complexity, and aeration mixed solution active sludge is aging, and water inlet contains excessive washing composition or tensio-active agent, and thread fungus is expanded etc.The foam that the aeration tank water surface produces can have a strong impact on the normal operation of sewage treatment process, makes operation, operation and the control of sewage work all produce certain difficulty, has a strong impact on effluent quality.When foam is serious even can surpass the superelevation of pond body, overflow the pond body, this is contaminate environment not only, and has potential harm for operator, the personnel that on the body of pond, walk can since foam coverage fall in the pond accidentally at Chi Tishang.
Therefore, in the design process of conventional sewage treatment structure, can add the water treatment defoaming device according to water quality usually.Defoaming device commonly used is generally one-sided water inlet, water yield inequality, and water yield shakiness, and the water source need be external, and cost is higher.
The utility model content
The problem that the utility model solves is to provide a kind of sewage treating and de-foaming device, and water outlet is uniform and stable, and cost is lower.
In order to solve the problems of the technologies described above, the technical solution of the utility model is:
A kind of sewage treating and de-foaming device comprises:

As preferably, described pumping plant is two, and the water entry that the two ends of described water transfer pipe network are provided with links to each other with two pumping plants respectively, sets out water spot in the described water transfer pipe network.
As preferably, described pumping plant is placed on below the water surface 0.8m～1.5m of settling tank, at the bottom of the settling tank more than 1.8m～2.2m.
As preferably, the every adjacent water exit spacing of described water transfer pipe network is 15cm～25cm.
As preferably, described water exit is provided with the spiral water distributor.
As preferably, described water exit is provided with valve.
The sewage treating and de-foaming device that the utility model provides adopts the water in the settling tank in the Sewage treatment systems, and cost is lower, and is intake simultaneously by the both sides of aeration tank, the active balance water yield, and water outlet is uniform and stable.
Description of drawings
The sewage treating and de-foaming device synoptic diagram that Fig. 1 is provided for a kind of embodiment of the utility model;
The sewage treating and de-foaming device synoptic diagram that Fig. 2 is provided for another embodiment of the utility model.
Embodiment
In order further to understand the utility model, below in conjunction with embodiment the utility model preferred embodiment is described, but should be appreciated that these describe just to further specifying feature and advantage of the present utility model, rather than to the restriction of the utility model claim.
The invention provides a kind of sewage treating and de-foaming device, comprise the pumping plant that is placed in the settling tank, be connected with pumping plant and be arranged in water transfer pipe network on the water surface of aeration tank, water transfer pipe network is provided with the water exit to aeration tank water surface water spray, the two ends of water transfer pipe network are provided with water entry respectively, and water entry links to each other with pumping plant respectively.
Please refer to Fig. 1, the sewage treating and de-foaming device synoptic diagram that Fig. 1 is provided for a kind of embodiment of the present invention.Placing a submersible pump 3 in the settling tank 1 is pumping plant, submersible pump 3 is extracted the waste water in the settling tank 1 out and is sent to water transfer pipe network 4, water transfer pipe network 4 is laid on the water surface of aeration tank 2, the waste water that comes out from submersible pump 3 is divided into two water entry water inlets, be separately positioned on water transfer pipe network 4 and be positioned at the two ends of 2 relative both sides, aeration tank, be water entry 41 and water entry 42, waste water enters water transfer pipe network 4 by both sides can equilibrium water amount, aquifer yield is uniform and stable, and do not need external water source, the waste water of settling tank in the direct using system, cost is lower.As preferably, submersible pump 3 is placed on below the water surface 0.8m～1.5m of settling tank 1, more than 1.8m～2.2m, both can prevent that winter, water body freezed at the bottom of the settling tank, avoids again the mud of settling tank 1 bottom extracted out and stops up water transfer pipe network 4.The every adjacent water exit spacing of water transfer pipe network 4 is preferably 15cm～25cm, and water is evenly distributed in certain radius, to reach froth breaking purpose preferably.Water exit preferably is provided with spiral water distributor 43, simple in structure, be easy to processing, water distribution is even.For flexible control, preferred mounted valve all at each water exit place, ball valve for example is so that artificially adjust the size of the aquifer yield of water transfer pipe network 4 each water exit.
Please refer to Fig. 2, the sewage treating and de-foaming device synoptic diagram that Fig. 2 is provided for another embodiment of the present invention, this embodiment is provided with two submersible pumps, submersible pump 31 links to each other with the water entry 41 of water transfer pipe network 4, submersible pump 32 links to each other with water entry 42, waste water is that the both sides by water transfer pipe network 4 enter equally, and aquifer yield is uniform and stable.
The technology of the sewage treating and de-foaming device that use the utility model provides comprises: the waste water in the settling tank is extracted out, and the both sides relative by the aeration tank are distributed on the water surface of aeration tank by water transfer pipe network.
Waste water in the use settling tank does not need external water source as the water source of sewage froth breaking in the aeration tank, can save cost.The a lot of water exit of distributed quantity on the water transfer pipe network guarantees uniformly waste water to be distributed on the water surface of aeration tank.The water outlet water yield of each water exit preferably can be regulated, and makes that control is more flexible, can realize the pointwise froth breaking.As preferably, the water outlet water yield of each water exit is 5L/h～12L/h in the water outlet pipe network.
