The aeration rate is 2-2.5 mg/L, and aeration is carried out at intervals through the aeration of the aerobic tank and the non-aeration of the facultative tank and anaerobic tank, so as to carry out the simultaneous nitrification and denitrification reaction.

A constant temperature system is also included, and the constant temperature system is in the form of an electric heating rod fixed on the side wall of the reactor through a suction cup.

When the present invention is used, the form of aeration is stage aeration along the length of the reactor, and the plug-flow water flow operation is adopted, so that the stability of the reactor is better, the energy consumption is less, and the space is more economical , and is conducive to sampling to observe the growth of microorganisms on the carrier.

The material of the reactor is plexiglass, which is transparent and can better observe the growth of microorganisms and the condition of the membrane. It is a cuboid-shaped pool without a cover sealed by silica gel. The inner wall is thickened with plexiglass strips, and a fixed biofilm carrier is reserved. The position of the insert.

The separation membrane module is vertically placed in the reactor in the form of a frame interlayer soft cloth material, so that it is completely or partially submerged in water. Each part of the separated area can generate an independent microbial system, and at the same time, the separation membrane module also plays a role in intercepting the biomass, ensuring the average distribution of the biomass in the longitudinal length of the reactor and the quality of the effluent.

The cloth material of the separation membrane module uses a woven cloth material. The material body has a certain aperture and because of the use of woven cloth, the aperture has high stability, strong impact resistance, and is not easy to deform. One or both sides of the surface Fibers are available for growth of microorganisms. In addition to retaining biomass and supplying microbial attachment and growth, it also has a certain interception effect on suspended pollutants. Even for working conditions with a short hydraulic retention time, the system can also ensure a certain biodegradation efficiency. The retained biomass generally settles at the bottom of the reactor. On the one hand, these microorganisms will provide an anaerobic environment inside, on the other hand, due to the low concentration of pollutants, they will stay in the endogenous respiration period, which can be expected to provide an internal carbon source.

The present invention adopts the method of interval aeration to oxygenate, and produces uneven distribution of oxygen in the space inside the system, thus creating good conditions for synchronous nitrification and denitrification for denitrification. At the front end of the reactor, low-intensity aeration is adopted, because At the water inlet, the COD concentration in the system is relatively high, and the carbon source is organic matter that is easily biodegradable, and the front end of the reactor is in a local anaerobic state. Subsequent facultative and anaerobic zones are not aerated and are in an anaerobic state. The aerobic tanks in the second group of reaction tanks are aerated again, while the facultative tanks and anaerobic tanks in the second group are not aerated, thereby increasing the DO value inside the cell. Finally, there is no aeration in the last facultative and anaerobic tanks of the system, and the dissolved oxygen content shows a downward trend. In doing so, the dissolved oxygen in the system is unevenly distributed, so that the nitrifying bacteria in the aerobic environment have a good nitrification effect, and the nitrate and nitrite produced are denitrified by the microorganisms in the anaerobic environment in the system, thereby achieving synchronous nitrification Denitrification.

Example:

As shown in Figures 7 to 10, this embodiment uses artificially synthesized sewage, and the water quality is stable and easy to control. The carbon source is used as glucose, and the nutritional ingredients added are 400 gm/L of carbon source glucose, 25 mg/L of nitrogen source ammonium chloride, and 3 mg/L of phosphorus source potassium dihydrogen phosphate. The test process adopts A/O method to test.

As shown in Figure 7, it is the curve diagram of the present embodiment to the COD removal situation, the curve in Figure 7 is to adopt the continuous operation mode to operate, the hydraulic retention time is 6.5H, adopts the method for compartment aeration, and the measured COD The effect of removal. It can be seen from Figure 5 that in the case of partial aeration in the reactor, the reactor has a good removal effect on COD, and the removal rate is above 85%.

As shown in Figure 8, it is a curve diagram of the removal of ammonia nitrogen after the use of this embodiment. Figure 8 shows that the reactor has an excellent removal effect on ammonia nitrogen, and the removal efficiency of ammonia nitrogen reaches more than 90% stably, and the ammonia nitrogen in the reactor effluent The concentration is stable at 2.0mg/L.

Figure 9 is a graph showing the removal of nitrate after use in this example. Figure 9 shows that the concentration of nitrate in the reactor effluent is generally within 4 mg/L, and the effluent quality is excellent. Observe the reactor itself, the front of the reactor is black, but the aeration is still in progress, indicating that the aeration at the front of the system is insufficient, and the distribution of dissolved oxygen in the reactor is uneven, which makes the system have better denitrification. So that the concentration of nitrate in the effluent is not high.

At the same time, after testing, the concentration of nitrite is almost undetectable when the water is discharged, and no nitrite is added to the influent water, so the nitrite in the water can be regarded as the product of the nitrosation reaction, and the nitrite is detected The concentration is very low, indicating that the reactor has good nitrification.

As shown in Figure 10, it is the ability diagram of the removal of total nitrogen after the use of this embodiment. As can be seen from Figure 10, when the ammonia nitrogen in the influent is 18-24mg/L, the total nitrogen in the effluent is generally within 5.5mg/L, indicating that it has Better ability to remove ammonia nitrogen, the removal rate of ammonia nitrogen is stable above 90%, and the removal rate of total nitrogen reaches 79-90%.

When the present invention is used, the main function in the early stage of use is to rely on the aperture of the honeycomb hole 13 of the fabric to filter the solid matter in the liquid; after a period of operation, microorganisms will multiply on the membrane material 14, and the accumulated microorganisms will change the aperture of the original fabric. Small, forming micropores occupied by microorganisms, the tiny pore size improves the filtration accuracy, and at the same time forms an ideal bioreactor under the three-dimensional microbial coverage; the ring-type terry or long-pile tissue structure provides ideal microbial growth In space, the reaction membrane carries anaerobic, facultative and aerobic microorganisms. When the growth of microorganisms affects the filtration effect, it is only necessary to increase the oxygen exposure on the surface of the reaction membrane to make the anaerobic microorganisms in the innermost layer fall off and make the blocked The pore size gap becomes larger and the filtering effect is restored.

When the present invention is used, it breaks through the concept of solid-liquid separation using microporous membrane materials in traditional water treatment, adopts self-filtering materials with large apertures and non-linear drainage channels, and uses the filtered material as the filtering material to filter itself, so that the filtering material and The filter material is integrated to form a filter membrane, which can effectively achieve solid-liquid separation and greatly reduce the investment and operating costs of the solid-liquid separation part of the water treatment reactor. At the same time, because the drainage channel of the self-filtering material is a non-linear drainage channel and the filtering gap is three-dimensional, a large part of the microorganisms in the water treatment reactor can be trapped in the reactor, and the amount of activated sludge in the reactor can be increased and maintained. , and prolong the sludge age of the sludge in the reactor, thereby reducing the cost of water treatment and operating costs.
