Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sewage treatment device capable of improving the effects of nitrogen removal and phosphorus removal. Background Art

[0002] Nitrogen and phosphorus are one of the main causes of eutrophication of water bodies. The sources of nitrogen in water bodies include metabolism and corruption of organisms, discharge of industrial wastewater and domestic sewage, loss of nitrogen fertilizers, etc. In order to effectively improve eutrophication of water bodies, it is very necessary to develop an economical, efficient and environmentally friendly denitrification process. In the process of denitrification and dephosphorization of sewage by existing devices, the catalyst reacts with sewage to produce precipitation. The precipitation will not only settle to the bottom of the tank, but also adhere to the side wall of the tank. If the accumulation of precipitation on the inner wall of the tank is allowed, it will have a certain impact on the subsequent sewage treatment effect. Patent documents have been made to improve this.

[0003] For example, Chinese patent CN216426844U discloses a small integrated device for treating wastewater for denitrification and dephosphorization. The device comprises a tank body, a stirring mechanism, a cleaning mechanism and a switching mechanism. The switching mechanism is used to control the opening and closing of the switching mechanism. By setting the stirring mechanism, the cleaning mechanism and the switching mechanism, the stirring mechanism can accelerate the mixing efficiency of the wastewater and the catalyst in the tank body, thereby accelerating the denitrification and dephosphorization efficiency of the wastewater. The cleaning mechanism can clean the sediment adhered to the inner wall of the tank body after the device has been operated for a long time, so as to avoid excessive sediment adhered to the inner wall of the tank body affecting the effect of the next wastewater treatment, thereby improving the practicality of the device. The switching mechanism can freely control the operation of the cleaning mechanism, so that the stirring mechanism can be operated alone during the denitrification and dephosphorization operation of the wastewater, which reduces the loss of electric energy to a certain extent and further improves the practicality of the device.

[0004] Although the device in the above document can switch the device by starting the electric telescopic rod, so that it can both mix and stir and drive several brushes to rotate to clean the inner wall, it still has obvious defects in actual use, such as:

[0005] Although the equipment can use a rotating brush to clean the inner wall of the tank, the brush is composed of dense burrs and has many gaps. After long-term use, a large amount of impurities will be mixed on the surface and in the gaps of the brush, losing its original cleaning function, so that the inner wall of the tank cannot be effectively cleaned during subsequent cleaning of the tank. If the brush is not cleaned and replaced in time when the tank is in a closed state, it will indirectly affect the service life of the equipment;

[0006] Therefore, a sewage treatment device that can conveniently clean the tank body and the brush and improve the nitrogen and phosphorus removal effect is now designed to solve such defects. Utility Model Content
