The utility model discloses a theory of operation: the device simulates the natural ecosystem and has a long food chain consisting of a plurality of microorganisms. The multifunctional flora on the carrier is in a dormant state when in contact with the wastewater and the biological additives, and the flora is quickly changed from the dormant state to an active state. Organic substances in the wastewater are adsorbed to thalli within about 10-30 min in a short time, and soluble substances directly penetrate into cell membranes. Under the action of intracellular enzyme, the nutritive matter entering the cell is made to produce a series of biochemical reactions to convert organic matter into carbon dioxide, water and other simple inorganic matter and produce energy. The microorganisms synthesize cell substances by using energy released by respiration and intermediate products generated in the oxidation process, so that the thalli are propagated in large quantities. The microorganism continuously carries out biological oxidation, so that organic matters in the environment are continuously reduced, and the sewage is purified.

The movable microorganism carrier and the fixed microorganism carrier are separated by a porous clapboard, and an aerobic zone, a facultative zone and an anaerobic zone are formed in the equipment under the long-term action of water flow.

The device can be divided into an area with higher oxygen content in a convection area, an area with a corner of a reaction tank as a non-convection area and almost very little oxygen content, an area with higher oxygen content in a connection area of the two areas than the corner of the reaction tank, and an optimal living environment of microbial communities. Different microorganisms can perform respiration and fermentation on different types of carbohydrates, so that the carbohydrates are continuously degraded into simple inorganic matters, and the purpose of treating pollutants in water is achieved.

No matter the number of the sewage treatment mechanisms connected in series, the I-shaped water inlet pipe 1 and the I-shaped water outlet pipe 4 are both arranged at the same horizontal position.

The microorganism carrier in the device is divided into a fixed microorganism carrier 7 and a movable microorganism carrier 3, which are made of wood through special processing. In the manufacturing process, components which are easy to cause wood rot are removed, a certain amount of cellulose, lignin and pentosan components are preserved, physical treatment is carried out, the porosity of the components reaches 75-85% which is suitable for the growth of microbial flora, and the components become a carrier in a living state after the cultivation and cultivation of microorganisms, and the carrier is characterized in that a fixed microbial carrier 7 enables the microbial flora not to be easily lost, the microbial phase tissue is stable, the organic matter treatment efficiency is high, the microbial carrier in the system does not need to be replaced, the carrier is semi-permanent, and usually, after the system runs for 3-5 years, only a small amount of supplement is needed every year; 2 the mobile microorganism carrier 3 is suspended in water, and the contact area of gas, liquid and solid phases is increased. Different microbial carriers provide hosts and survival conditions for microbes of different attributes.

The microporous aeration pipe 7 is made of special material and has a superfine air supply function, a plurality of fine I-shaped pores are arranged on the pipe, and the section of each micropore has a certain inclination, so that the air bubbles are not only fine and dense, but also can be automatically closed when the air supply is stopped, and the blockage is prevented. The aeration pipe has the advantages of excellent material, advanced technology and good aeration effect, and is easy to form the optimal hydraulic state required by biological purification. The aeration device adopts a patent suspension system, and the system can be maintained without stopping. It has the following five functions:

(1) micro-bubble generation: has high oxygen dissolution rate;

(2) ultrasonic bubble movement: has high chemical combination effect;

(3) the high-speed water flow action: the water flow speed is strong and stable;

(4) micro flora effect: promoting the generation of a large amount of micro flora;

(5) is suitable for the symbiotic living environment of anaerobic bacteria, facultative bacteria and aerobic bacteria.

Because the depth of the pore in the sewage treatment device is different and the distribution of aeration quantity is not uniform, the anaerobic zone, the facultative zone and the aerobic zone coexist in the same tank body. Therefore, when sewage passes through each treatment tank body, the sewage passes through aerobic, facultative and anaerobic processes repeatedly, and the sewage treatment effect is greatly enhanced. Due to the special good environment provided by the sewage treatment device, the biological phase in the system is rich, the biological activity is high, a very good ecological system is formed, and pollutants in water are completely decomposed.

The device can be connected with a plurality of sewage treatment mechanisms in series to achieve the purpose of repeated biochemical and continuous treatment, and the specific serial connection mode is adjusted according to the type and the treatment capacity of the treated sewage.

Example (b):

in the embodiment, three filtering mechanisms are connected in series, and the series connection of the three filtering mechanisms is favorable for continuously decomposing and digesting the polluted organic matters in the water. The sewage is self-flowed by gravity in the serial sewage treatment device. All the devices are three-phase fluidized bioreactors formed by special flora, and biological carriers and efficient microporous aeration pipes are arranged in the three-phase fluidized bioreactors. By setting the position of the microporous aeration pipe and setting the aeration quantity, anaerobic, facultative and aerobic areas with different structural proportions can be generated in the device, namely the A/A/O process is formed. Therefore, the capacity of resisting water flow impact load and organic matter impact load of the system can be effectively improved.
