Abstract

The invention discloses a graphene modified electrically antibacterial membrane element, and an electrically antibacterial treatment system. The graphene modified electrically antibacterial membrane element comprises a membrane shell, a membrane element, a raw water inlet, a raw water outlet, end sockets, double-clip type quick joints, and seal washers; the internal side of each double-clip type quick joint is provided with graphene modified conductive hollow membrane wires; the gaps between the graphene modified conductive hollow membrane wires, and the graphene modified conductive hollow membrane wires and the membrane shell are filled with a graphene modified conductive pouring sealant; each of the four contact surfaces of the graphene modified conductive hollow membrane wires with the membrane shell is provided with a conductive copper ring; the conductive copper rings on the upper parts are connected with copper binding posts; the bottom parts of the membrane shell close to the internal sides of the graphene modified conductive hollow membrane wires are provided with produced water outlet pipes. The graphene modified electrically antibacterial membrane element is capable of killing and inhibiting bacteria, and solving problems such as operation pressure difference is large, and membrane element flux is reduced because of microbial pollution, and avoiding operation cost increasing and membrane wire aging caused by frequent adding of oxidizing bactericides.

Description

technical field [0001] The invention relates to a water treatment device, in particular to a graphene-modified electric bacteriostatic membrane element and an electric bacteriostatic treatment system thereof. Background technique [0002] Today's world's ecological environment is deteriorating day by day, and water pollution has become a global problem. It not only hinders the country's industrial development, but also affects the living environment of human beings. As water pollution continues to intensify, water treatment objects are even more diverse. Traditional water treatment technology has been unable to solve complex problems. Only by combining with new technologies can problems be effectively solved. Based on the above reasons, water treatment technology has made great progress in recent years, and its important sign is the extensive application of membrane technology. Although membrane technology has developed rapidly, compared with other technologies, the develop...
