Description

TECHNICAL FIELD

[0001] The utility model belongs to water treatment technical field, concretely relates to a reclaimed water filtering equipment. BACKGROUND

[0002] The emergence and development of the reclaimed water filtering equipment is based on the dual needs of water resource shortage and environmental protection. With the acceleration of industrialization and urbanization, the demand for water resources is increasing, while the supply of traditional water resources is becoming increasingly tight. Therefore, the reclaimed water filtering equipment emerges as the times require. It can be reused in the fields of industry and life by treating wastewater to meet the specified water quality standards, effectively improving the utilization rate of water, saving costs and water resources. The main functions of the reclaimed water filtering equipment include removing suspended solids, organic matter, microorganisms, and salt and other impurities in water to make the water purer. Among them, the quartz sand filter is mainly used to remove suspended solids in water, and the activated carbon filter is mainly used to adsorb free chlorine, organic matter, and color in water. With the continuous development of technology, modern reclaimed water filtering equipment also uses higher quality materials, has higher filtering precision and stronger durability, and can more effectively remove impurities in water.

[0003] The existing reclaimed water filtering equipment may have the following disadvantages if it does not have a spray washing and stirring function: the impurities in the filtering medium may block the filter layer after long-term adsorption of impurities, which may increase the resistance of water flow through the filter layer, slow down the water flow speed, and even cause blockage, thereby affecting the filtering efficiency. If the old filtering medium is not thoroughly cleaned or replaced, a large amount of impurities, particulate matter, and microorganisms may remain in it, which may occupy the effective voids of the new filtering medium and reduce its filtering capacity.
