Abstract
The invention relates to a high-efficiency internal-circulation biological aerated filter and a combined rural sewage treating system, belonging to the field of sewage treatment technology. The high-efficiency internal-circulation biological aerated filter comprises a water inlet in the bottom of the filter, a biological filter material layer located at the center of the filter, a water outlet in the upper part of the filter and an air pipe extending to the bottom of the filter, wherein the air outlet of the air pipe is provided with an aeration head; a vertical guide cylinder extending from top of the filter to bottom of the filter is arranged in the filter; and the air pipe is located in the guide cylinder and extends to the bottom of the filter from top to bottom. According to the invention, a traditional A2O process arranged in a manner of plane combination is changed into an A2O process arranged in a manner of vertical surface combination; the guide cylinder extending from top of the filter to bottom of the filter is arranged in the filter so as to realize internal circulation of wastewater in a tank from top to bottom under the stripping action of the guide cylinder; thus, treatment effect is improved. The combined rural sewage treating system comprises the high-efficiency internal-circulation biological aerated filter and constructed wetland which are successively connected; and the combined rural sewage treating system guarantees biochemical treatment effect, realizes filtering of suspended solids and prevents subsequent constructed wetland from blocking.
Description
Technical field
The present invention relates to sewage disposal technology, particularly to a kind of BAF, further relate to a kind of rural sewage treatment system.
Background technology
BAF（Biological Aerated
Filter）It is a kind of New biological membrane method sewage treatment process, this technique has removal SS, COD, BOD, nitrification, denitrogenation, dephosphorization, removes AOX（Harmful substance）Effect, be collection biological oxidation and retention suspended solid one new technology, save post precipitation pond (second pond), there is volumetric loading, hydraulic load greatly, hydraulic detention time is short, and required capital expenditure is few, effluent quality is good, and operation energy consumption is low, the few feature of operating cost.
The aeration tube horizontality of traditional BAF, located at the bottom of pond portion, after the water inlet pipe from the bottom of pond portion for the sewage enters pond body, carries out biological carbon and phosphorous removal process from the bottom to top, and the delivery port from pond body top for the water after process is discharged.
Content of the invention
The technical problem to be solved is to provide a kind of BAF of high-efficiency internal circulation formula, and provides the rural sewage treatment system of a kind of BAF of this high-efficiency internal circulation formula and artificial wetland combination.
The technical problem to be solved is achieved by the following technical programs：
A kind of high-efficiency internal circulation BAF, water inlet including filter tank bottom, the biological filter bed of material in the middle part of filter tank, the delivery port on filter tank top, also include the air hose towards filter tank bottom, the gas outlet of air hose is provided with aeration head, is additionally provided with the vertical guide shell leading to filter tank bottom from filter tank top in filter tank.
Preferably, described air hose is located in guide shell, from top to bottom leads to filter tank bottom.
A kind of combined type rural sewage treatment system, including the above-mentioned high-efficiency internal circulation BAF being sequentially connected and artificial swamp.Wherein Artificial Wetland Techniques are known in the art general knowledge, and here no longer elaborates.
The present invention has the advantages that：
The A2O technologic improvement of plane combination is combined arrangement for facade by the high-efficiency internal circulation BAF of the present invention, it is provided with the guide shell from top to bottom leading to filter tank bottom, make waste water pass through the interior circulation that guide shell is realized from top to bottom in the presence of stripping in pond, improve treatment effect.
The combined type rural sewage treatment system of the present invention, is core process technology using inner circulating aerating biological filtering tank, more auxiliary in artificial swamp, realize effective improvement of sanitary sewage it is ensured that whole system can be stablized normally runs.Inner circulating aerating biological filtering tank achieves the single pond of A2O biological carbon and phosphorous removal treatment technology with it is ensured that achieve the filtering it is ensured that follow-up artificial swamp is not in the problem of blocking of suspension while Biochemical Treatment again.
Brief description
Fig. 1 is the structural representation of the present invention.
Specific embodiment
The present invention will be described in detail with reference to the accompanying drawings and examples.
As shown in Figure 1, a kind of high-efficiency internal circulation BAF, water inlet 1 including filter tank bottom, the biological filter bed of material 2 in the middle part of filter tank, the delivery port 6 on filter tank top, it is provided with the vertical guide shell 4 leading to filter tank bottom from filter tank top in this filter tank, in guide shell 4, is provided with the air hose 5 towards guide shell 4 bottom, air hose 5 bottom connects aeration head 3.
This filter tank is when carrying out sewage disposal, sewage enters filter tank by water inlet 1 first, due to being provided with the biological filter bed of material 2 in filter tank, it is additionally provided with the air hose 5 towards filter tank bottom in filter tank, the lower end of air hose 5 is provided with aeration head 3, therefore can achieve anaerobic-anoxic-good A2O biological carbon and phosphorous removal treatment effect supported from the bottom to top.Due to being additionally provided with the vertical guide shell 4 leading to filter tank bottom from filter tank top in this filter tank, after waste water rises on air hose 5, filter tank bottom can be back to from guide shell 4, the interior circulation that therefore waste water can be realized from top to bottom by guide shell in the presence of stripping in pond, increases treatment effect.
A kind of combined type rural sewage treatment system, including the above-mentioned high-efficiency internal circulation BAF being sequentially connected and artificial swamp.Sewage carries out achieving the filtration of suspension while efficient biochemical treatment it is ensured that follow-up artificial swamp is not in the problem of blocking in high-efficiency internal circulation BAF again.
Embodiment described above only have expressed embodiments of the present invention; its description is more concrete and detailed; but therefore can not be interpreted as the restriction to the scope of the claims of the present invention; in every case the technical scheme being obtained in the form of equivalent or equivalent transformation, all should fall within the scope and spirit of the invention.
