Abstract

The utility model discloses a single-hole membrane aerator comprising an upper pipe clamp (1) and a lower pipe clamp (8) that are connected on a vent pipe, wherein the upper pipe clamp is internally provided with a groove; the groove is communicated and connected with the inner cavity of the vent pipe (7) by a vent hole (9) and internally provided with a membrane (2); the periphery of the membrane is fixed by a fixing cover (3); the cross section of the membrane (2) is I-shaped; and the intermediate layer of the membrane is provided with an aeration hole (4). The upper pipe clamp (1) and the lower pipe clamp (8) are connected by a dovetail groove structure (6); the intermediate layer of the membrane can generate up and down microvibration with bigger frequency under the action of air pressure, thus leading the air passing through the membrane to form a large amount of small air bubbles which then escape from the aeration hole in the middle of the membrane, greatly increasing the specific surface areas of the air bubbles, improving the utilization ratio of oxygen, being beneficial to microbial metabolism, and greatly enhancing the aeration biological treatment effect; the upper pipe clamp and the lower pipe clamp of the aerator are connected by the dovetail groove; and a round hole for ventilation is changed to a square hole which not only can be used for ventilation but also can be assembled or disassembled by a spanner, thus facilitating assembly and disassembly, relieving the work intensity of assembly and disassembly, and lowering the treatment cost.

Description

The single hole menbrane aerator

Technical field

The utility model relates to the single hole menbrane aerator that is used for BAF.

Background technology

The organism and the nitrogen ammonia of, complex structure big at molecular weight in sanitary sewage and the trade effluent, difficult degradation are more, the problem that the general method processing efficiency is lower.Mostly adopt biological aerated filter process that effluent sewage is handled in the prior art with advantages such as handling the load height, treatment effect is good, floor space is little.And the microorganism oxygen requirement mainly forms supply by having the effect of diaphragm-operated aerator in the BAF processing, and existing single hole diaphragm aerator mainly has following deficiency: the one, and the diaphragm forced deformation is fixed on aerator top, diaphragm can not make the air of feeding produce more micro-bubble, the bubble surface area that forms is less, coefficient of oxygen utilization is not high, be unfavorable for a large amount of formation of microorganism, thereby treatment effect is not high enough; Be the dismounting of the component part up and down inconvenience of existing aerator again, dismounting is long man-hour, and working strength is big, increases the processing cost expense.

The utility model content

At above-mentioned problems of the prior art, the utility model provides a kind of compact construction simple, easy accessibility, and the effective single hole menbrane aerator of aeration.

The technical scheme that the not high enough technical problem of existing BAF aerator treatment effect to be solved in the utility model is taked is: described single hole menbrane aerator comprises last pipe clamp and the lower tube clip that is connected on the ventpipe, in last pipe clamp, be provided with groove, groove is connected by ventilating pit and ventpipe inner chamber, in groove, be provided with diaphragm, diaphragm is fixed with fixed cap, described diaphragm cross section is I-shaped, described diaphragm middle layer can produce little shaking up and down under the air pressure effect, make air form the micro-bubble aeration, described diaphragm middle layer is provided with solarization air cap.

Fast aerator is carried out dismounting for more convenient, lower tube clip adopts the dovetail structure to connect on the aerator described in the utility model, and the production well on the described aerator on the fixed cap of pipe clamp is arranged to square opening.

The utility model is owing to become middle cross section I-shaped than what approach diaphragm arrangement, the diaphragm middle layer can produce bigger little the shaking up and down of frequency under the air pressure effect, thereby can make and form a large amount of micro-bubbles by the air on the diaphragm and from diaphragm intermediary solarization air cap, overflow, increase the specific surface area of bubble greatly, improved the utilization ratio of oxygen, help microorganism metabolism, improved the aeration and biological treatment effect greatly; The upper and lower pipe clamp of aerator adopts dovetail-indent to connect, and changes the circular hole of ventilating into square hole, both can ventilate, and available dedicated wrench fast assembling-disassembling is installed easy accessibility again, has alleviated disassemble and assemble work intensity, has reduced the expense cost of handling.
