Description

Technical Field

[0002] Wastewater refers to the general term for water discharged during residents' activities and runoff rainwater. It includes domestic sewage, industrial wastewater, and other unused water such as initial rain runoff into drainage pipes. It generally refers to water that cannot be recycled after certain technical treatment or water that cannot meet certain standards for purification after primary pollution. In the process of wastewater treatment, it is necessary to pre-treat the wastewater to filter out the garbage or impurities carried by the wastewater, so as to facilitate further treatment of the wastewater. Wastewater filtration devices are usually used for wastewater filtration. During the use of wastewater filtration devices, since some of the filtered impurities will adhere to the filter net, the filter net needs to be cleaned, and the filter net is usually cleaned by backwashing.

[0003] During the backwashing process of the wastewater filter device, the filter screen is usually cleaned, but impurities attached to the inner wall of the wastewater filter device cannot be removed by flushing, resulting in an excessive amount of impurities on the inner wall of the wastewater filter device, which will cause the capacity of the wastewater filter device to decrease. Therefore, a backwashing wastewater filter device that is easy to clean is proposed. Utility Model Content
