An example of application of the integrated sewage treatment apparatus of the present utility model will be described in detail with reference to fig. 5.

First, wastewater is fed into the anoxic tank 1 through a pipe connected to the wastewater inlet 10. The anoxic tank 1 is filled with suspended fillers inoculated with denitrifying bacteria, such as polyurethane sponge suspended fillers, filiform fiber fillers and the like. The function of the suspended filler is to provide a proper production environment for denitrifying bacteria by utilizing the extremely high specific surface area of the suspended filler, and the nitrate in the water body is reduced to N gas by mixing and stirring of a stirrer under the condition of low oxygen amount through a large amount of denitrifying bacteria cultured in the suspended filler so as to reduce the nitrogen content in sewage. In the denitrification reaction of the anoxic tank 1, a carbon source is an indispensable element, and when the soluble organic matters in the wastewater are insufficient, the carbon source required in the denitrification process is provided by supplementing chemical substances. Thus, the anoxic tank 1 and the carbon source inlet 20 may be connected by a pipe, where appropriate, so that the oxygen tank 1 is supplemented with a carbon source, which may be selected from one of glucose, sodium acetate, methanol, or a combination thereof, through the carbon source inlet 20.

Then, the treated water after denitrification treatment in the anoxic tank 1 is transported to the conversion tank 2 through a pipe. The conversion tank 2 is a reaction tank which can be converted for use, and can be used as an anoxic tank and an aerobic tank. In particular, the conversion tank 2 has a basic structure similar to that of the anoxic tank 1, for example having the same rectangular cross section, in which a stirrer is provided. Unlike the anoxic tank 1, the bottom of the conversion tank 2 is also provided with an aeration pipe connected to an air pump 61 in the pump house 6 through a pipe.

When the denitrification capability of the anoxic tank 1 is insufficient, the conversion tank 2 can be used as the anoxic tank, namely, suspended filler inoculated with denitrifying bacteria is put in the anoxic tank, the aeration pipe is closed to avoid the rise of the oxygen content in the water body, and the agitator is started to continuously perform denitrification treatment on the treated water conveyed from the anoxic tank 1. During this time, if the amount of soluble organic matters in the wastewater is insufficient, the conversion tank 2 and the carbon source inlet 20 may be connected through a pipe as well, thereby replenishing the carbon source into the conversion tank 2 through the carbon source inlet 20.

Or when the nitrogen content in the treated water conveyed by the anoxic tank 1 reaches the standard, the denitrification treatment is not needed to be continued (at this time, the carbon source is not needed to be supplemented). At this time, the aeration pipe may be started, and the oxygen content may be increased by introducing air into the conversion tank 2, so that the oxygen content may be converted into an aerobic tank for use. At this time, a suspension filler inoculated with oxidizing microorganisms, for example, a polyurethane sponge suspension filler, a filamentous fiber filler, or the like, may be put into the conversion tank 2. The suspended filler is used for adsorbing organic matters in the wastewater, and the organic matters are oxidized and decomposed by microorganisms under the aerobic condition, so that the wastewater is purified. The organic matters adsorbed on the suspended filler are finally converted into suspended waste after catabolism and carried away by water flow.

And then, the treated water treated by the conversion tank 2 is conveyed into the first aerobic tank 3 and/or the second aerobic tank 4 through a pipeline. The first aerobic tank 3 and the second aerobic tank 4 can be arranged in a backup mode, any one of the two tanks can be independently operated, the other one is idle or overhauled, and the two tanks can be operated simultaneously as required, so that the parallel processing capacity is improved. In a specific embodiment, the first aerobic tank 3 is preferably provided with a stirrer, in which polyurethane sponge suspended filler inoculated with oxidizing microorganisms is put in, and the mixing of the water body and the suspended filler is accelerated by the stirrer. The second aerobic tank 4 is not provided with a stirrer, and a filiform fibrous filler inoculated with oxidizing microorganisms is fixedly arranged therein. By arranging different fillers in the first aerobic tank 3 and the second aerobic tank 4, the types and the amounts of organic matters which can be adsorbed and carried by the different fillers are slightly changed, so that different types of sewage treatment combinations can be provided for the whole treatment equipment. Of course, the first aerobic tank 3 and the second aerobic tank 4 can also adopt the same arrangement, and can adopt the design with a stirrer at the same time, can adopt the design without a stirrer at the same time, can also adopt the design without a stirrer of the first aerobic tank 3, and can also adopt the design without a stirrer of the second aerobic tank 4, and the filler can be flexibly put in according to different water bodies to be treated so as to realize the function of modularization expansion. The first aerobic tank 3 and the second aerobic tank 4 are used for oxidizing organic matters, so that aeration pipes connected with an air pump 61 in the pump room 6 through pipelines are arranged at the bottoms of the first aerobic tank 3 and the second aerobic tank 4. In addition, the nitrogen-containing organic matters oxidized by the first aerobic tank 3 and the second aerobic tank 4 can be converted into nitrate and nitrite, so that the first aerobic tank 3 and the second aerobic tank 4 can reflux and convey the oxidized water body into the anoxic tank 1 through pipelines for denitrification treatment again, and the nitrogen content in the water body is reduced to the maximum extent through repeated circulation.

As described above, the first aerobic tank 3 and the second aerobic tank 4 may be used alone, may be used in parallel, or may be used in series. That is, the water body treated by the first aerobic tank 3 can be directly conveyed to the sedimentation tank 9 through a pipeline, or can be firstly conveyed to the second aerobic tank 4, then conveyed to the sedimentation tank 9 through a pipeline after being treated by the second aerobic tank 4.

The sedimentation tank 9 may be of any conventional structural design with a sludge sedimentation function, for example, a separation inclined tube, a bottom mud scraper, a top overflow trough and the like may be arranged in the sedimentation tank 9. In order to promote the separation, the sedimentation tank 9 may be provided with an aeration pipe connected to the air pump 61 in the pump room 6 through a pipe, and aeration is performed to the lower side of the separation chute through the air pump 61 to promote the separation of the sediments through the air flow. After the water body delivered to the sedimentation tank 9 is treated, the upper clear water can be discharged via a pipe to the water discharge outlet 30. The bottom sludge of the sedimentation tank 9 can be scraped into a middle sludge hopper by a sludge scraper, then input into a sludge pipe 91 through a two-way parallel pipeline, and then discharged through a sludge discharge outlet 40.

While the sludge is discharged through the sludge pipe 91, the sludge can be input into the sludge storage tank 8 connected with the sludge pipe 91, and the sludge is intensively discharged through the sludge discharge port 40 after the storage amount is enough. In order to achieve better treatment effect, a branch pipe can be further arranged in the sludge pipe 91, and the branch pipe is used for re-inputting sludge discharged from the sedimentation tank 9 into the anoxic tank 1, the first aerobic tank 3 and the second aerobic tank 4, and the content of harmful substances in the water body is reduced through repeated denitrification and oxidation treatment. At this time, the sludge discharged from the sedimentation tank 9 is preferably not discharged from the sludge discharge port 40 but is fed into the sludge storage tank 8, and is fed from the sludge storage tank 8 into the sludge pipe 91, and is fed into the anoxic tank 1, the first aerobic tank 3 and the second aerobic tank 4 through the branch pipes to be subjected to the repetitive cycle treatment.

Further, a flow measuring tank 7 communicating with the sludge pipe 91 may be provided downstream of the sludge storage tank 8 for feeding part of the sludge into the flow measuring tank 7 through the sludge pipe 91. Denitrifying bacteria can be added into the sludge in the flow measuring tank 7, and a carbon source can be supplemented into the flow measuring tank 7 through the carbon source inlet 20, so that strain culture preservation is performed in advance in the sludge in the flow measuring tank 7, and meanwhile, sufficient carbon source is supplemented into the sludge. When restarting after the system is suspended, bacteria-containing and carbon-containing sludge pre-stored in the flow measuring tank 7 can be input into the anoxic tank 1 through a pipeline, so that the working environment in the anoxic tank 1 is quickly restored to a normal state, and the system can be quickly started. Or in the case of insufficient capacity of the mud storage tank 8, the flow measuring tank 7 may be used as the mud storage tank 8, and the function and operation of the flow measuring tank 7 are the same as those of the mud storage tank 8.

The structure and process of treating sewage using the integrated sewage treatment apparatus of the present utility model are described above in detail by way of example only. Various control and actuating mechanisms such as solenoid valves, flow meters, level meters, delivery pumps and the like for controlling the opening of the pipelines can be arranged in each pipeline in fig. 5, and the arrangement and structure of the mechanisms of the utility model can be easily realized by a person skilled in the art according to the written description and the drawings or with reference to common general knowledge in the art. The control and actuation mechanism described above may be controlled and operated by a distribution box provided in the distribution room 5.

In summary, the integrated sewage treatment equipment of the utility model divides the interior of the container-type cuboid structure into a plurality of rectangular-section functional spaces through the partition plates, and can set different functional spaces to different purposes according to the needs, so that the integrated sewage treatment equipment can be modularly expanded, and can set a proper outline according to the needs of convenient movement and transportation.
