Description

A kind of aerator for high concentration suspended matter immersion type membrane component

Technical field

The utility model belongs to technical field of sewage, particularly relates to a kind of aerator for high concentration suspended matter immersion type membrane component.

Background technology

In the submerged membrane system of disposing of sewage, sewage is provided to many employings perforated pipe of disturbance and aeration oxygen replenishing, the membrane module bottom adopting in tradition MBR membrane bioreactor generally also adopts perforated pipe aerating regulation, and most of gas stirs for muddy water, and small part is for increasing oxygen in water.

Because flco in activated sludge is little, when stirring, easily to break up, density is light, and sludge concentration is below 20000mg/L, and suitable approximately 8000mg/L, has exceeded 30000mg/L, and mud is dense thick without the concentrated property of precipitation, is difficult to improve and realizes in submerged membrane treatment system. So the design aeration mode of existing membrane module is applicable to biochemical process, tolerance with gas-water ratio 12:1 compared with core, the about 6h of hydraulic detention time.

The range of application of submerged ultrafiltration has had further expansion at present, conventional membrane bioreactor and water treatment field are not limited to, processing water and suspension characteristic for immersion type membrane component are necessary specific aim optimization aeration mode, meet the requirement of membrane module under different operating condition. Penetration hole diameter 5 ~ the 7mm of tradition aeration perforated pipe, spacing 100mm, arrange from film curtain away from, mainly utilize gas duck in drink rise form backwater effect, drive current rise, utilize between ascending current and film silk and rub, reach the wiping of suspension of film silk surface adhesion, realize the effect that film silk superficial layer upgrades. In the time processing low concentration suspension, because concentration of suspension is low, density is light, the water velocity that air pocket drives just can meet the demands, and also can slow down film silk two ends and middle fixed position and assemble bulk suspension;

But under new condition, immersion type membrane component more than high concentration suspended matter 30g/L, the concentration of suspension is higher, between suspension, there is self-adhesive, density is larger, settling rate is fast, in separation muddy water process, film silk outer surface concentration of suspension is higher, more easily between film silk outer surface and film silk, form high concentration region, time one is long, in situation that disturbance is not enough, between film silk, high concentration suspended matter district concentration of suspension can be more long-pending higher, and moisture content is more and more lower, assembles bulk mud and the middle bad phenomenon that forms bulk mud pie of film silk thereby formed film silk two ends. This phenomenon is mainly because the disturbance deficiency of air-flow and current causes, there is no the feature for concentration of suspension raises between film silk in mud-water separation process, therefore need to be for high concentration suspended matter submerged membrane separation assembly, strengthen targetedly disturbance and the scouring intensity of film, prevent two ends and film silk staging bulk mud pie.
