Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a domestic wastewater treatment device. Background Technology

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, healthcare, and catering, and is increasingly becoming a part of everyday life. Wastewater can generally be divided into industrial wastewater and domestic wastewater. Industrial wastewater includes industrial wastewater, agricultural wastewater, and medical wastewater, while domestic wastewater is the wastewater generated in daily life, referring to a complex mixture of various forms of inorganic and organic matter.

[0003] Currently, kitchen wastewater accounts for a large proportion of domestic wastewater. The main components of kitchen wastewater are leftover food and water, with organic matter such as starch, dietary fiber, and animal fat as the main components. It is characterized by high nutrient content, high water content, high oil and salt content, and easy to ferment and smell. Therefore, it needs to be treated before being discharged. The existing treatment method is to discharge the wastewater into the wastewater pond for sedimentation, using the principle of gravity settling to separate water and impurities, thereby achieving impurity removal. However, this passive method of natural separation of water and impurities may result in incomplete separation, affecting the wastewater treatment effect. Utility Model Content

[0004] The purpose of this utility model is to provide a domestic wastewater treatment device to solve the above-mentioned problems.

[0005] This utility model achieves the above-mentioned objectives through the following technical solution: a domestic wastewater treatment device, including a base, on which a first treatment tank and a second treatment tank are disposed. A filter cylinder is detachably installed inside both the first and second treatment tanks. Multiple filter holes are provided on the side wall of the filter cylinder, and a retaining ring is provided at the opening of the filter cylinder. A connecting ring for engaging with the retaining ring is provided on the inner side wall of both the first and second treatment tanks. The interior of both the first and second treatment tanks is divided into an inlet chamber and an outlet chamber by the connecting ring. An inlet tee pipe and an outlet tee pipe connect the first and second treatment tanks. The inlet tee pipe communicates with the inlet chamber, and the outlet tee pipe communicates with the outlet chamber.

[0006] As a further feature of this invention, both the first and second processing tanks are provided with an opening and a cover for closing the opening. Several bolts are connected to the cover, and several nuts matching the bolts are provided on the top of the first and second processing tanks.

[0007] As a further feature of this invention, a connecting seat is provided on the outer side wall of both the first and second processing tanks, and a support arm is rotatably connected to the connecting seat. The support arm is connected to the cover via a connecting rod.

[0008] As a further feature of this invention, both the first and second processing tanks are provided with drain pipes at their bottoms, the drain pipes are connected by a connecting pipe, and a first valve is provided between the drain pipes and the connecting pipe.

[0009] As a further feature of this invention, a second valve is provided on both the inlet tee and the outlet tee.

[0010] As a further feature of this invention, the filter cylinder is provided with a lifting handle.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In use, wastewater can be fed into the first and second treatment tanks through the inlet tee. The wastewater first flows into the inlet chamber, where the filter cartridge removes impurities, allowing clean water to flow through the filter holes into the filter cartridge. As the wastewater continues to flow in, the filter cartridge continuously filters it, causing the clean water level to rise until it overflows from the filter cartridge's opening and enters the outlet chamber. Finally, it is discharged through the outlet tee, thus achieving wastewater treatment. During this process, the filter cartridge actively filters the wastewater, achieving active separation of water and impurities. The slow rise of the wastewater within the first and second treatment tanks also serves to settle the wastewater, ensuring more thorough separation of impurities and improving the wastewater treatment effect. After use, the filter cartridge can be removed for individual cleaning to prevent filter hole blockage and extend the device's lifespan. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1 , Figure 3As shown, the domestic wastewater treatment device includes a base 1, on which a first treatment tank 2 and a second treatment tank 3 are mounted. Filter cylinders 4 are detachably installed inside both the first treatment tank 2 and the second treatment tank 3, and multiple filter holes are formed on the side wall of the filter cylinder 4. A retaining ring 5 is provided at the opening of the filter cylinder 4, and connecting rings 6 are provided on the inner side walls of both the first treatment tank 2 and the second treatment tank 3 for engaging with the retaining rings 5. The first treatment tank 2 and the second treatment tank 3 are connected by the connecting rings. The device is divided into an inlet chamber 7 and an outlet chamber 8. An inlet tee pipe 9 and an outlet tee pipe 10 connect the first treatment tank 2 and the second treatment tank 3, respectively. The inlet tee pipe 9 is connected to the inlet chamber 7, and the outlet tee pipe 10 is connected to the outlet chamber 8. When the device is in use, wastewater can be introduced into the first treatment tank 2 and the second treatment tank 3 through the inlet tee pipe 9. The wastewater will first flow into the inlet chamber 7, where, due to the obstruction of the filter cartridge 4, impurities carried in the wastewater are filtered out, resulting in a dry... Clean water flows into the filter cylinder 4 through the filter holes. As wastewater continues to flow in, the filter cylinder 4 continuously filters the wastewater, causing the level of clean water to rise until it overflows from the opening of the filter cylinder 4 and enters the outlet chamber 8. Finally, it is discharged through the outlet tee pipe 10, thus achieving wastewater treatment. In this process, the filter cylinder 4 actively filters the wastewater, achieving active separation of water and impurities. The wastewater rises slowly in the first treatment tank 2 and the second treatment tank 3, which also serves to settle the wastewater, allowing impurities to be separated more thoroughly. This ensures the thoroughness of water and impurity separation and improves the wastewater treatment effect. After the device is used, the filter cylinder 4 can be removed for separate cleaning to prevent the filter holes from clogging, thereby extending the service life of the device. The filter cylinder 4 is equipped with a lifting handle 20, which can be held to apply force when installing or removing the filter cylinder 4, making the installation and removal of the filter cylinder 4 more convenient and labor-saving.
