Small-sized water purification device integrating micro electric flocculation and unpowered single valve filter

Abstract

The invention relates to a small-sized water purification device integrating micro electric flocculation and an unpowered single valve filter. The small-sized water purification device comprises a raw water tank, the single valve filter, a backwash water tank, an ultraviolet sterilizer and a water seal well, wherein an overflow pipe is arranged on the side surface of the upper part of the raw water tank, a concave electrolytic reaction zone is formed at the bottom of the raw water tank, an aluminum electric flocculation pole plate externally connected with a 6-12 V direct-current stabilized power supply is arranged in the electrolytic reaction zone; the bottom of the electrolytic reaction zone communicates with one end of a U-shaped water inlet pipe, and the other end of the U-shaped water inlet pipe communicates with the top of the single valve filter; the bottom of the backwash water tank communicates with the bottom of the single valve filter through a backwash water inlet pipe, a water outlet pipe is connected with the upper part of the backwash water tank, the ultraviolet sterilizer is connected with the middle of the water outlet pipe, and a user water tank is connected with the tail end of the water outlet pipe; a backwash drainage pipe is inserted into the water seal well, and one end of the backwash drainage pipe communicates with the top of the single valve filter; a water collection zone, a supporting layer and a filter material layer are arranged in the single valve filter from bottom to top sequentially. The small-sized water purification device is simple to operate, and the pollutant removing effect is remarkable.

Description

technical field [0001] The invention relates to the technical field of rural drinking water treatment, in particular to a micro-electric flocculation-non-powered single-valve filter tank integrated small water purification device. Background technique [0002] Northwest China is one of the areas with the most water shortage and the most severe drinking water safety situation in the world. Residents in this area are scattered and the cost of water supply is high. The water problem seriously restricts the economic and social development of the western area. Although the rainwater storage projects in recent years have solved the problems of drinking water for people and livestock in the area, supplementing irrigation for drought resistance, and increasing income for seedlings, the rainwater stored in the water cellar is vulnerable to solid waste (domestic garbage, animal feces, etc.), air pollution, etc. chemicals, pesticides and fertilizers, and other pollution caused by human...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the existing domestic water purification equipment is aimed at municipal pipe network water supply and drinking water source water with good water quality, while the rural residents in Northwest China generally have a low level of education and do not have the ability to operate complex equipment
