[0014] The technical effects and advantages of this utility model are:

[0015] The utility model has a reasonable structure. The sewage is squeezed into the filter shell by the provided water pump. Since the clean water pipe is provided in the filter shell, the sewage is impacted on the inner wall of the filter shell through the clean water pipe under the action of the water pump and is ejected outwards through the filter cloth. The stains in the sewage are retained on the inner wall of the filter cloth. The larger stains are retained in the space formed between the filter shell and the clean water pipe under the action of gravity and turbulence, which is convenient for collecting the stains in the sewage. In addition, due to the provided detachable filter assembly, the filter shell can be directly pulled out through the top cover for replacement after a period of use, which can prevent the filter assembly from being blocked and the filtering effect from being weakened, and is more convenient to use.

[0016] In the present invention, the turbine blades are set so that the turbine blades start to rotate under the impact of the water flow gushing out from the filter component, and the toggle rod also starts to stir under the action of the turbine blades. Under the action of the turbine blades and the toggle rod, the water flow inside the outer bin starts to rotate and flow, preventing the stains in the sewage from settling inside the outer bin, so that the stains are collected by the filter component, reducing the adhesion of the stains inside the device, thereby reducing the number of times the device is cleaned, and it is simpler and more convenient to use. Moreover, the rotating turbine blades drive the toggle rod to lift the bacteria house, which can increase the contact area between the nitrifying bacteria in the bacteria house and the sewage, accelerate the biochemical treatment, and make the purification effect better. The water flow after biochemical treatment by the biochemical component passes through the separation net and returns to between the outer bin and the separation net again. The sewage is continuously circulated inside the entire device and is continuously purified. While ensuring the purification effect, the area occupied by the device is greatly reduced.

[0027] The filter housing 9 is provided with a filter housing 10, and the filter housing 10 is provided with a filter housing 11. The filter housing 10 is provided with a filter housing 10, and the filter housing 10 is provided with a filter housing 11. The filter housing 10 is provided with a filter housing 10, and the filter housing 10 is provided with a filter housing 10 ... The influx of water drives the turbine blades 13 installed on the central column 8 to rotate, causing the turbine blades 13 to start rotating. Under the action of the turbine blades 13, the toggle rod 16 also starts stirring. Under the action of the turbine blades 13 and the toggle rod 16, the water flow inside the outer chamber 1 begins to rotate and flow, and the bacteria house 18 placed between the central column 8 and the partition net 17 is also lifted up, increasing the contact area between the nitrifying bacteria in the bacteria house 18 and the sewage, accelerating the biochemical treatment, and the water flow after biochemical treatment by the biochemical component passes through the partition net 17 and returns to the outer chamber 1 and the partition net 17 again. The sewage circulates continuously inside the entire device and is continuously purified. Compared with the existing technology, the space of the device can be greatly reduced by setting a continuously circulating treatment process, which facilitates the installation and placement of the device. At the same time, the filter component can be conveniently stored to store stains and facilitate the replacement of the filter shell 9, which can avoid the filter component from being blocked and weakening the filtering effect, making it more convenient to use.

[0028] like Figure 1 、 Figure 2 and Figure 5 As shown, the filter assembly includes a filter housing 9 movably mounted on the top of the central column 8. A clean water pipe 10 is fixedly provided at the bottom of the filter housing 9. The clean water pipe 10 connects the inside and outside of the filter housing 9.

[0029] The sewage is pumped into the central column 8 by the water pump 7, and then enters the filter shell 9 through the central column 8. Since a clean water pipe 10 is provided in the filter shell 9, the sewage is impacted on the inner wall of the filter shell 9 through the clean water pipe 10 under the action of the water pump 7, and is ejected outward through the filter cloth 11. The stains in the sewage are retained on the inner wall of the filter cloth 11. Under the action of gravity and turbulence, the larger stains are retained in the space formed between the filter shell 9 and the clean water pipe 10, which is convenient for collecting the stains in the sewage.

[0031] After being filtered by the filter assembly, the water flows through the holes on the central column 8 into the space between the central column 8 and the partition net 17. The influx of water drives the turbine blades 13 installed on the central column 8 to rotate, causing the turbine blades 13 to start rotating. Under the action of the turbine blades 13, the toggle rod 16 also starts stirring. Under the action of the turbine blades 13 and the toggle rod 16, the water flow inside the outer chamber 1 begins to rotate and flow, and the bacteria house 18 placed between the central column 8 and the partition net 17 is also lifted up, which can increase the contact area between the nitrifying bacteria in the bacteria house 18 and the sewage, accelerate the biochemical treatment, and the water flow after the biochemical treatment by the biochemical assembly passes through the partition net 17 returns to between the outer bin 1 and the partition net 17 again, and the sewage circulates continuously inside the entire device and is continuously purified, which greatly reduces the footprint of the device. Compared with the existing technology, the biochemical component set up can not only stir the water flow to prevent the stains in the sewage from settling inside the outer bin 1, but also collect the stains through the filtering component, reducing the stains adhering to the inside of the device, thereby reducing the number of times the device is cleaned, and it is simpler and more convenient to use.
