Treatment system for sea water desalination and water purification

Abstract

The invention relates to the technical field of water purification treatment equipment and provides a treatment system for sea water desalination and water purification. The treatment system comprises a settling tank, a water tower, a fresh water tank and a purified water tank, which are orderly connected by use of pipelines; the water tower is arranged on a water tower base having a certain height; a pressure pump is arranged on the pipeline connected between the settling tank and the water tower; a water inflow chamber is arranged at the water inlet of the pipeline of the settling tank; a primary filter layer is connected to the surface of the water inflow chamber; the primary filter layer comprises a plurality of layers of filter screens dope with graphene or graphitic alkyne; the fresh water tank is provided with a secondary filter layer transversely penetrating through the middle of the fresh water tank; the secondary filter layer comprises a supporting substrate and a graphene or graphitic alkyne nano-film attached on the supporting substrate. The water purification treatment system is high in water purification treatment speed, good in water purification treatment effect, high in water purification treatment universality and low in water purification treatment cost.

Description

technical field [0001] The invention relates to the technical field of water purification treatment equipment, in particular to a water purification treatment system. Background technique [0002] With the development of the economy, the crisis of water resources has become increasingly prominent. How to obtain clean water from seawater or sewage purification has attracted more and more attention. Taking seawater desalination as an example, seawater desalination is one of the important ways to solve the global water crisis. There are many methods for seawater desalination. At present, in terms of technical types, distillation and reverse osmosis are the two mainstream technologies. The energy consumption of stills is high, which is not suitable for large-scale production; reverse osmosis technology has become an advanced desalination technology due to its high efficiency, low energy consumption, cleanliness, and convenient operation and management. However, after years of r...

Problems solved by technology

The energy consumption of stills is high, which is not suitable for large-scale production; reverse osmosis technology has become an advanced desalination technology due to its high efficiency, low energy consumption, cleanliness, and convenient operation and management. However, after years of research and development, its The improvement space is close to the limit, and its practical application is seriously limited in terms of processing speed and processing cost; taking industrial sewage or domestic sewage treatment as an example, membrane technology is widely used at home and abroad, such as "double membrane filtration" method, "multi-membrane filtration" 95% of microorganisms, suspended solids and macromolecular pollutants in sewage can be intercepted through microporous membranes, but such methods are not yet thorough in purification treatment, and there is still room for improvement in the purification effect
