In recent years, extreme climate caused by greenhouse gases causes the water circulation system to suddenly change, extreme floods and drought (too much water/too little water) frequently occur, and the supply and demand of water resources are seriously unbalanced. In view of this, there is a major investment in research and development of water technology, such as: advanced sea water desalting technology is developed, and a sewage circulating system with high reuse rate is established for agricultural irrigation and the like. Various new water sources are actively developed, including sea water desalination, new water utilization and the like, and the new water technology is purified water produced by three layers of treatment of domestic sewage through impurity filtering, reverse osmosis and ultraviolet disinfection. However, the current seawater desalination technology has high water production cost, and can not be used as a scheme for solving the problem of civil water resources. In the water circulation process, domestic sewage generated by a common household or wastewater discharged by a public institution is generated, and the unclean water usually needs to be treated to reach a certain discharged water quality before returning to the nature. In the future, when water is one of important water resources, a water recycling concept of using one drop of water at least twice by means of technology is established. The water recycling is to recycle industrial wastewater, domestic sewage, rainwater storage and utilization, agricultural irrigation return water, seawater utilization and other water.

The second is the self-developed composite porous material, and MOF with high hole rate and large hole volume is crosslinked with adsorbent such as chitosan to form composite porous solid material, so as to enhance the selective adsorption capacity of MOF to heavy metal ions. Second, the second molecular sieve material layer 302 has low molecular sieve density and excellent abrasion resistance, can bear high pressure and friction force in the sewage treatment process, and has good long-term stability.
