Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a recycled water treatment and filtering device. Background Art

[0002] Recycled water refers to the water that has been used in the production process. After proper treatment, its water quality and water temperature meet certain standards and is recycled for use in another system. This water can be industrial wastewater or urban sewage that has been reused after secondary treatment and deep treatment. It is also called recycled water or reclaimed water. The quality of recycled water is between sewage and tap water. After meeting national standards, it can be used as non-drinking water within a certain range and can be used in many aspects of urban landscape and people's lives.

[0003] Before being treated, recycled water is generally stored in a sewage pool, and then the recycled water in the pool is pumped up by sewage treatment equipment for filtration treatment. However, most of the current sewage treatment equipment directly inserts the pumping pipe into the sewage pool for pumping and filtering when in use. However, due to the lack of filtering structure at the pumping pipe, it is easy to directly pump up a large amount of particulate matter deposited in the sewage pool and inject it into the filtering equipment, increasing the burden of the filtering equipment. Therefore, it is necessary to design a recycled water treatment filtration device that can effectively perform preliminary filtration at the pumping pipe to solve the above problem.
