Sewage treating and de-foaming process provided by the invention and device adopt the water in the sedimentation basin in the sewage disposal system, 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 schematic diagram that Fig. 1 is provided for a kind of specific embodiment of the present invention;
The sewage treating and de-foaming device schematic diagram that Fig. 2 is provided for another specific embodiment of the present invention.
The specific embodiment
In order further to understand the present invention, below in conjunction with embodiment the preferred embodiment of the invention is described, but should be appreciated that these describe just to further specifying the features and advantages of the present invention, rather than to the restriction of claim of the present invention.
Sewage treating and de-foaming process provided by the invention comprises: the waste water in the sedimentation basin 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 sedimentation basin 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 EXIT POINT 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 EXIT POINT 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 EXIT POINT is 5L/h～12L/h in the water outlet pipe network.
The present invention also provides a kind of sewage treating and de-foaming device, comprise the water plug that is placed in the sedimentation basin, be connected with water plug and be arranged in water transfer pipe network on the water surface of aeration tank, water transfer pipe network is provided with the EXIT POINT 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 water plug respectively.
Please refer to Fig. 1, the sewage treating and de-foaming device schematic diagram that Fig. 1 is provided for a kind of specific embodiment of the present invention.Placing an immersible pump 3 in the sedimentation basin 1 is water plug, immersible pump 3 is extracted the waste water in the sedimentation basin 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 immersible 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, water yield is uniform and stable, and do not need external water source, the waste water of sedimentation basin in the direct using system, cost is lower.As preferably, immersible pump 3 is placed on below the water surface 0.8m～1.5m of sedimentation basin 1, more than 1.8m～2.2m, both can prevent that winter, water body freezed at the bottom of the sedimentation basin, avoids again the mud of sedimentation basin 1 bottom extracted out and stops up water transfer pipe network 4.The every adjacent EXIT POINT 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.EXIT POINT preferably is provided with spiral water-locator 43, simple in structure, be easy to processing, water distribution is even.For flexible control, preferred mounted valve all at each EXIT POINT place, ball valve for example is so that artificially adjust the size of the water yield of water transfer pipe network 4 each EXIT POINT.
