Abstract

A water purification and filtration system capable of reducing backwashing water consumption comprises filter tanks; a water inlet tank and an emptying tank are arranged at the front end of each filter tank; each water inlet tank communicates with a water inlet pipe and communicates with the corresponding filter tank through a water inlet butterfly valve; each emptying tank is provided with a drainage pipe; a filter plate is mounted at the lower part of each filter tank through a filter plate supporting beam, a plurality of short-handle filter heads are mounted on each filter plate, and a filter material layer is placed on each filter plate; a U-shaped drainage channel is arranged above the filter material layers and communicates with the emptying tanks through drainage butterfly valves; awater outlet pipe is arranged below the rear end of each filter tank; a backwashing operation room, a water collecting tank and a water outlet water sealing well are arranged at the rear end of eachfilter tank; each water outlet water sealing well communicates with a water collecting tank; each water collecting tank is provided with a clear water pipe and a backwashing water supply pipe; each water outlet water seal well communicates with the water outlet pipe through a water outlet valve and a water passing pipe; each water outlet pipe is connected with a backwashing water inlet pipe through a water inlet valve; the lower part of each filter tank communicates with a backwashing gas inlet pipe. The system ensures that the water quality is stable and reaches the standard and saves backwashing water at the same time.

Description

technical field [0001] The invention relates to the technical field of water treatment in water plants, in particular to a water purification and filtration system used in small water purification plants to reduce backwash water consumption and improve flushing effect. Background technique [0002] The water production process of a water plant generally consists of flocculation-sedimentation-filtration-disinfection, etc. Among them, the filter is the last process of routine treatment of water purification structures, and the operation of the filter directly affects the quality of the effluent of the water plant. With the promulgation of new standards for drinking water quality by the Ministry of Health and the Ministry of Construction, all domestic water supply companies will improve the quality of effluent water as a top priority. In the purification process of drinking water, filtration is not only to further reduce the turbidity of water, but also to partially remove orga...
