Description
Technical field
The utility model relates to a kind of sewage water denitrification device.
Background technology
BIF is called for short in biological filter, is with soil self-purification principle for foundation, artificial bio-membrane's treatment technology that the practical basis of sewage irrigation grows up.The features such as it has stronger adaptability to the change of sewage quality, the water yield, convenient management, sludge bulking can not occur, and the excess sludge of generation is few, having very high clearance to nitric wastewater, is use more treatment process in the middle of Modern sewage treatment process.But this technique also exist floor space large, need pond body quantity many, the shortcomings such as ratio between investments is large.
Summary of the invention
The utility model, in order to solve the problem of prior art, provides a kind of sewage water denitrification device.
For achieving the above object, the technical solution adopted in the utility model is: a kind of sewage water denitrification device described in the utility model, comprise pond body and retaining filter vat, water distributor is provided with above the body of described pond, described pond body inner homogeneous is provided with ammonification layer, nitrated layer and denitrification layer, body inside, described pond is provided with agitator arm, described agitator arm is provided with paddle, rising pipe is provided with bottom the body of described pond, described pond body is connected with retaining filter vat by rising pipe, described retaining filter vat inside is provided with three filtering nets, water trap is provided with bottom described retaining filter vat, described nitrated layer and denitrification layer inside are provided with heating unit and temperature inductor, described rising pipe and water trap are respectively arranged with control valve and flow control meter.
As preferably, described ammonification layer, nitrated layer and denitrification layer inside are respectively arranged with ammonification filler, nitrated filler and denitrification filler.
As preferably, described water distributor is provided with water distribution pipeline.
The utility model structure is simple, and design ingenious, floor space is little, can effectively process nitrogenous useless.This is a kind of new technical scheme, is convenient to promote the use of.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
As shown in Figure 1, a kind of sewage water denitrification device described in the utility model, comprise pond body and retaining filter vat 4, water distributor 2 is provided with above the body of described pond, described pond body inner homogeneous is provided with ammonification layer 11, nitrated layer 1 and denitrification layer 12, body inside, described pond is provided with agitator arm 3, described agitator arm 3 is provided with paddle 31, rising pipe 5 is provided with bottom the body of described pond, described pond body is connected with retaining filter vat 4 by rising pipe 5, described retaining filter vat 4 inside is provided with three filtering nets 9, water trap 6 is provided with bottom described retaining filter vat 4, described nitrated layer 1 and denitrification layer 12 inside are provided with heating unit 14 and temperature inductor 13, described rising pipe 5 and water trap 6 are respectively arranged with control valve 7 and flow control meter 8.
It should be noted that described ammonification layer 11, nitrated layer 1 and denitrification layer 12 inside are respectively arranged with ammonification filler, nitrated filler and denitrification filler.
It should be noted that and described water distributor 2 is provided with water distribution pipeline 10.
The utility model adopts: described water distributor comprises feedback pond, siphoning installation, distributing pipe line and nozzle composition, after sewage enters feedback pond certain altitude, siphoning installation is started working, sewage enters water distribution pipeline, nozzle is arranged on water distributor, be positioned at filter material surface 0.15-0.2m, be evenly sprayed on filtrate by nozzle water flow.
Described ammonification layer 11, nitrated layer 1 and denitrification layer 12, by polymer plastic and fiber draw composition, run through by plastic ties and connect, filler adheres to ammonifying bacteria, nitrifier and denitrifying bacteria.
Sewage enters ammonification layer 11 from water distributor and then enters nitrated layer 1; Ammonia nitrogen in sewage and organonitrogen decompose, are converted into nitrate.Consume the dissolved oxygen in water simultaneously.Finally enter denitrification layer 12, by denitrifying bacteria, nitrate dress is turned to nitrogen under anoxic conditions; Filtered by rising pipe retaining filter vat 4 inside of entering afterwards, be distributed to each through water trap and use water place.
The standardized parts that the utility model uses all can be commercially, shaped piece all can carry out customized according to specification sheets with the record of accompanying drawing, the concrete mode of connection of each part all adopts the conventional means such as bolt, rivet, welding ripe in prior art, machinery, part and equipment all adopt in prior art, conventional model, add that circuit connects and adopt mode of connection conventional in prior art, be not described in detail in this.
The above is only better embodiment of the present utility model, therefore all equivalences done according to structure, feature and the principle described in the utility model patent claim change or modify, and are included in the utility model patent claim.
