AI Technical Summary

Technical Problem

Existing non-powered ultrafiltration membrane systems are easily affected by high-turbidity raw water at rural drinking water stations, and are difficult to maintain and lack shock resistance.

Method used

The non-powered membrane water purification system, consisting of an ejector, membrane tank, and product water tank, utilizes siphon force and an air-collecting pulse aeration device to achieve automatic water production, chemical washing, and drainage. Large air bubbles are used to flush the membrane modules, reducing reliance on electricity and electric valves.

Benefits of technology

It achieves highly efficient water purification without the need for electricity, reduces operating costs and maintenance complexity, enhances the system's shock resistance and lifespan, and simplifies the maintenance process.

Abstract

The utility model provides an anti-impact unpowered membrane water purification system and relates to the technical field of water treatment. The utility model provides a water purification system. The water purification system comprises an ejector (1), a membrane pool (2) and a water production tank (3) which are sequentially communicated, the jet device (1) is communicated with a water distributor (21) of the membrane tank (2) and is used for introducing air into water to be treated to form a gas-solid-liquid mixed solution; power is not needed as a power source, and operation cost is low; electric or pneumatic valve control is not needed, the probability of part damage is reduced, rural discontinuous water use is utilized, water production can be automatically switched to emptying when the water use peak is low, operation and maintenance are simpler, and the service life is longer; large-bubble scouring is realized without air supply of an additional fan, and the surface of the membrane is effectively scoured; the composition is simple and the cost is low; and a three-way valve and a medicine storage box can be arranged to realize unpowered medicine washing.
