Problems solved by technology

The above experiments reduced the electric sterilization voltage to a lower voltage, and only achieved high sterilization effects on water with a very small flow rate, but it is difficult to be practical and is still far from the demand for sterilization water in daily life. Therefore, How to apply the current electric sterilization technology under low voltage to large flow water treatment is a necessary requirement for this technology to move towards life and production

Abstract

The invention discloses a high-efficiency bactericidal composite material under low-voltage high-speed water flow and a preparation method thereof. Firstly, the copper foam is pretreated; then the pretreated copper foam is heated by one-step oxidation to form acicular metal oxide nanowire structure; then a carbon film is deposited on the prepared nanowire material to form a conductive nanowire Multifunctional antiseptic material of carbon layer / foam metal oxide. The composite material prepared in the present invention utilizes the principle of electric field sterilization, and can quickly sterilize the water flowing through the water body under the applied low voltage and high water flow, and the sterilizing material is environmentally friendly and safe. The preparation method of the present invention is simple in operation, efficient in sterilization, low in cost, easy to realize macroscopic and controllable preparation, and is expected to be widely used in the fields of household water heater water treatment, breeding wastewater, ship ballast tank water treatment and the like.

Description

technical field [0001] The invention relates to the field of preparation of an online water body environment-friendly sterilization material, in particular to a high-efficiency sterilization composite material for water body under low voltage and high flow rate and a preparation method thereof. Background technique [0002] With the rapid development of the global economy, people's living standards are also improving day by day, but the corresponding environmental pollution is becoming more and more serious. Among them, the problem of water resources has seriously threatened the health of living people. 82% of people in our country drink water from shallow wells and rivers, and 75% of the aquaculture wastewater exceeds the hygienic standard. In recent years, typhoid fever, bacillary dysentery, infectious hepatitis, diarrhea and other diseases have occurred frequently in our country. related to water pollution, and these figures are on the rise every year. How to sterilize w...
