Abstract

The invention relates to the technical field of sewage purification and particularly relates to a graphene sewage purification combined device and a sewage purification method thereof. The graphene sewage purification combined device comprises a reactor, an ultrasonic wave generating device and a membrane separator, wherein a catalyst and multiple layers of graphene are arranged in the reactor. The sewage purification method comprises the following steps of: a) putting the multiple layers of graphene and the catalyst into the reactor, inputting sewage into the reactor, and enabling air to enter the bottom of the reactor; b) generating ultrasonic waves by the ultrasonic wave generating device, stripping the multiple layers of graphene to form single-layer graphene by the ultrasonic waves, and decomposing pollutants in the sewage through the single-layer graphene and the catalyst; c) enabling a water body after treatment in the step b) to enter the membrane separator; and d) discharging the water body from the membrane separator. According to the sewage purification method disclosed by the invention, various types of liquid can be treated continuously or intermittently, and the purposes of fast decomposition of the pollutants, disinfection and sterilization are realized.

Description

technical field [0001] The invention relates to the technical field of sewage purification, in particular to a graphene sewage purification combined device and a method for purifying sewage. Background technique [0002] With the development of society, the treatment of industrial waste liquid and domestic waste liquid has become a very serious social task. In order to save water resources and protect the natural environment, my country has strict requirements on the discharge of industrial waste liquids, and attaches great importance to the recycling of various waste liquids. [0003] At present, people often use adsorption technology to treat sewage. Adsorption technology refers to the use of activated carbon and other adsorption materials to adsorb various pollutants in water to reduce the concentration of pollutants in water, but its adsorption capacity is average and regeneration is difficult. In recent years, scientists have discovered that graphene has a huge specifi...
