Detailed Description

The invention will now be described in further detail with reference to the drawings and preferred embodiments. These drawings are simplified schematic views illustrating only the basic structure of the present invention in a schematic manner, and thus show only the constitution related to the present invention.

Example 1:

the integrated type super-efficient dissolved oxygen treatment reactor for printing and dyeing sewage comprises an ultra-fine pore dissolved air releaser 1 and a biochemical aerobic device 2, wherein the inner cavity of the biochemical aerobic device 2 is internally provided with the ultra-fine pore dissolved air releaser 1, the surface of the ultra-fine pore dissolved air releaser 1 is provided with a plurality of ultra-fine micropores 3, and the pore diameter of the ultra-fine micropores 3 is less than 0.2 um; the biochemical aerobic device 2 is formed by continuously connecting a plurality of single tank bodies in series, and the aerobic biochemical device is formed by connecting the single tank bodies h: 10 m-23 m are one-level, an air inlet pipe 7 is arranged at the lower part of each tank body, an ultramicropore dissolved air releaser 1 is arranged on the air inlet pipe 7, a water inlet 5 and a water outlet 6 are arranged at the top of each tank body, a water inlet pipe 4 extending into the inner cavity of the tank body is inserted into the water inlet 5, the lower end of the water inlet pipe 4 is close to the bottom surface of the inner cavity of the tank body, the water outlet 6 between the adjacent tank bodies is connected with the water inlet pipe 4, and a water outlet pipe 8 is also arranged on the tank body at the tail end in the biochemical aerobic device 2.

Meanwhile, the ultra-fine pore dissolved air releaser 1 is formed by mixing ultra-fine dissolved air releasing materials, ceramics, natural rubber, PVDF materials and other high-strength corrosion-resistant materials. As shown in figure 2, the ultramicropore dissolved air releaser 1 is in a curtain shape, because the ultramicropore dissolved air releaser 1 is formed by mixing a plurality of materials, a high-efficiency biological bacteria bed 10 is formed by a composed dissolved oxygen system, the inside of the bacteria bed 10 continuously conveys the dissolved oxygen to the outer surface, biochemical bacteria on the surface of the bacteria bed 10 firstly obtain the dissolved oxygen in fresh air, and the rest part quickly enters the whole water body, so that the inside of the biochemical aerobic device 2 can conveniently maintain the dominant bacteria for a long time, and when the membrane surface of the bacteria bed 10 falls off, the dominant bacteria are floated in the water body and become active bacteria particles.

The specific gas is fed through the gas inlet pipe 7, the air releases ultramicro bubbles through the ultramicro pore dissolved gas releaser 1 and enters the tank body of the biochemical aerobic device 2, the ultramicro bubbles can be dissolved in water in an ultramicro state within a period of time after entering the water body and flow forwards along with the water flow, and meanwhile, the micro bubbles can be quickly absorbed by biochemical bacteria, so that the utilization rate of oxygen is improved, and the ineffective oxygen consumption in the traditional oxygen supply is reduced;

when the water flow is pushed to move forward during working, the ultra-fine bubbles 9 dissolved in water flow forward synchronously with the water flow (because the ultra-fine bubbles cannot form an air chamber at the top of the tank), thereby greatly improving the utilization of the residual oxygen in the air; when the front-stage water enters the rear stage, the reactor automatically supplies when the dissolved oxygen is insufficient, so that accurate oxygen supply is achieved, and invalid waste in the biochemical aerobic equipment 2 is reduced;

in addition, biochemical sludge flows along with water in the water, a large number of flora exist on the biochemical sludge, a large number of ultramicro bubbles 9 are synchronously adsorbed, and the superfine bubbles can quickly permeate into the inner cavities of the microbial sludge particles, so that the biochemical bacteria are healthy and strong, and the biochemical system is efficient, stable and energy-saving;

and finally, the treated water in the tank body of the biochemical aerobic device 2 flows out through a water outlet 6.

Example 2:

the difference from example 1 is that: as shown in figure 3, the ultramicropore dissolved air releaser 1 is circular, air enters through an air inlet pipe 7 at the lower end, then enters 4 air distribution pipes on the air inlet pipe 7, and finally is sprayed out from ultrafine pores 3 fully distributed on the surfaces of the air distribution pipes to form a biochemical bacteria bed 10 on the surfaces of the air distribution pipes.

While particular embodiments of the present invention have been described in the foregoing specification, various modifications and alterations to the previously described embodiments will become apparent to those skilled in the art from this description without departing from the spirit and scope of the invention.
