Description

Technical Field

[0001] The utility model relates to filtering equipment for a water purification plant, in particular to filtering equipment for a water purification plant, and belongs to the technical field of water purification plants. Background Art

[0002] Water treatment plants draw water from rivers, purify and disinfect it, and then supply it to people for use. Water treatment plants are public facilities that form the basis of a water supply system that meets demand and provide tap water services. Filtration is an important step in the water purification process at a water treatment plant, and water treatment plants usually use filtration equipment to filter water.

[0003] A circulating filtration device for a water purification plant is disclosed in the Chinese patent application publication specification CN214270526U. The device can mix sewage and flocculant more fully, quickly and efficiently remove impurities in sewage, improve filtration efficiency, detect the treatment effect of sewage, and re-filter sewage that does not meet the standards.

[0004] However, during the implementation of the technical solution of the above patent, impurities in the filtering equipment cannot be discharged during the filtering process, resulting in the discharge of impurities affecting the filtering work.

During the filtration, impurities will remain inside the filtering equipment. It is necessary to stop the filtering work regularly and open the filtering equipment to clean the impurities. Such impurity cleaning process requires stopping the filtering work, which affects the filtering efficiency. Utility Model Content
