Abstract

The utility model discloses micro-pore aeration equipment. The micro-pore aeration equipment comprises a body (3), an air pore plate (2) and a rotary cover (4), wherein the body (3) is funnel-shaped; a plurality of aeration micro-pores are uniformly formed in the air pore plate (2); the rotary cover (4) is used for fixing the air pore plate (2) at the funnel end of the funnel-shaped body (3). The micro-pore aeration equipment provided by the utility model has the advantages of small aeration bubbles, low cost, small size, light weight, high processing efficiency and the like.

Description

A kind of micro-pore aeration equipment

Technical field

The utility model relates to a kind of micro-pore aeration equipment.

Background technology

Marine sewage treatment system generally adopts biochemical process to process, through the sewage of aeration aerating with the certain flow filler of flowing through, make to cover with microbial film on filler, sewage contacts with microbial film, under biomembranous effect, thereby aerobic bacteria is constantly engulfed organism sewage is purified; Aerating system is for the breeding of aerobic bacteria, and is biomembranously formed with very large effect.If oxygen concn is low, suppress the breeding of aerobic bacteria, thereby aerobic bacteria is just few, the microbial film of formation is just few, and it is just few that it has a liking for the organism falling, same organic content, the time of decomposition is just long, or under certain hour prerequisite, organic decomposition amount is just few.In the water of discharging like this, organic content is higher, can increase the weight of and destroy natural purification process and original eubiosis of water surrounding; , there is algae excessive Growth and reproduction in body eutrophication; Grow and propagate the disease to the harm of human health, and animals and plants existence is threatened.

In above-mentioned sewage disposal flow process, be substantially all that medium-and-large-sized sewage treatment unit dwindles plate, yet, because space is less, the aerating system of packaged unit adopts existing common aeration method, and in the same biochemical treatment time, the water of discharge detects generally all defective; At present, mostly adopt tube aerator, generally have aperture above aeration tube, have intermediate connection tube to supply gas to two, also have single-ended supplying gas, shortcoming is: pore atmosphere damages large, and energy consumption is high; Compact sewage treatment equipment floorage is little, and aeration tube length is shorter; Easily stop up; Aeration area is little; Bubble is large, and aeration is inhomogeneous, and coefficient of oxygen utilization is not high; In acid or alkali environment, erosion resistance is not high, and the replacement cycle is short; Also have some to adopt hose aeration, open aperture in the above, single-ended supplying gas, shortcoming is: easily stop up and stain; Packaged unit floorage is little, and pipe is short, and aeration area is little; Pore is large, consumes energy high; Bubble is large, and aeration is uneven, and coefficient of oxygen utilization is not high.

Summary of the invention

The utility model provides a kind of micro-pore aeration equipment, and it is little that this device has aeration bubble, and cost is low, device volume is little, lightweight, processing efficiency advantages of higher.

The utility model has adopted following technical scheme: a kind of micro-pore aeration equipment, and it comprises body spiracular plate, spiral cover, described body is funnel-form, is evenly provided with several aerating pores on spiracular plate, spiral cover is fixed on spiracular plate at the funnel end of funnel-form body.

In described body, be provided with check device; Described check device is ball shape, and the diameter of ball shape check device is greater than the opening diameter of body exit end; Described spiracular plate is comprised of aeration rubber plate and skeleton supporting plate, and aeration rubber plate is located at the surface of skeleton supporting plate, and both form one-piece construction, and on aeration rubber plate, correspondence is provided with several aerating pores.

The utlity model has following beneficial effect: the utility model adopts micropore design, aeration bubble is little, aeration is more abundant, by traditional concentrated stressed uniform stressed aeration that becomes, service area increases, and under same compressed-air actuated condition, bubble is wire and rises, gas-liquid area is large, stirring to water, is conducive to the lifting with mass-transfer efficiency that makes full use of of oxygen, has acid-alkali-corrosive-resisting, long service life simultaneously, can adapt to advantages such as being interrupted aeration; The aeration efficiency ratio tradition aeration efficiency of this aerating apparatus is high more than 60%, reduced the biochemical time, when pressurized air enters, micropore is bulging distending voluntarily, guarantee that air passes through, while stopping aeration, micropore is closed state, avoids through aerator hole blocking phenomenon, in body, be provided with check device and can prevent that aeration from stopping rear liquid refluence phenomenon, do not have simultaneously and can stop up, install and change conveniently, in long-time running, exempt the advantages such as maintenance.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.
