A device for treating wastewater based on graphene oxide quantum dot modified polysulfone ultrafiltration membrane

Abstract

The invention discloses a device for treating waste water based on graphene oxide quantum dot modified polysulfone ultrafiltration membrane, which comprises a waste water storage tank (a first sieve is embedded inside, a filter element is fixedly installed at the bottom, and the lower end is fixedly connected to the first The other end is fixedly connected with a constant flow pump, its water outlet is fixedly connected with a flowmeter, and its right end is fixedly connected with a filter box from left to right, (the filter box is embedded with graphene oxide quantum dot modification Polysulfone ultrafiltration membrane filter tank), mixing and decomposition chamber (embedded with ring-shaped disinfectant box, ring-shaped ultraviolet lamp, stirring motor and stirrer), flow meter, second valve, water collection tank (embedded with the first Two screens), the total processor and the first valve, constant flow pump, ultrafiltration membrane filter tank, disinfectant box inlet / outlet valve, mixing and decomposition chamber, annular ultraviolet lamp tube, second valve, stirring motor and Pressure temperature sensor connection. A high degree of purification of wastewater has been achieved.

Description

technical field [0001] The invention relates to a device for treating wastewater based on graphene oxide quantum dot modified polysulfone ultrafiltration membrane, which is a device with automatic operation, low cost and high purification efficiency, and belongs to the technical field of environmental protection. Background technique [0002] In recent years, with the continuous development of my country's industry and economy, a large amount of industrial wastewater containing heavy metals has been directly discharged into rivers without any treatment, which has caused a sharp increase in the content of heavy metals in the water environment, which has a negative impact on the ecological environment. Stability and human production and life pose a serious threat. Heavy metal pollutants are difficult to degrade in nature and are destructive to the environment. They have caused serious environmental pollution problems worldwide. In addition to industrial wastewater and urban sewa...

[0002] In recent years, with the continuous development of my country's industry and economy, a large amount of industrial wastewater containing heavy metals has been directly discharged into rivers without any treatment, which has caused a sharp increase in the content of heavy metals in the water environment, which has a negative impact on the ecological environment. Stability and human production and life pose a serious threat. Heavy metal pollutants are difficult to degrade in nature and are destructive to the environment. They have caused serious environmental pollution problems worldwide. In addition to industrial wastewater and urban sewage In addition to containing a large amount of organic matter, germs and viruses, it also contains various types and degrees of various toxic and harmful pollutants, which have also caused serious pollution to the environment.
