Abstract

Plasma technology has been studied and applied for water treatment in recent years. This technology reveals many advantages compared to conventional methods such as chlorination, ozonation, and UV. The plasma technology efficiently destructs or inactivates bacteria and micro-organisms. Furthermore, plasma can oxidize organic compounds and inorganic pollutants in water. This paper reviews the method to generate cold plasma from dielectric barrier discharges in air and results of water treatment by this method. This paper also summarizes conventional methods for water treatment and suggests research trends on cold plasma for water treatment in Vietnamese condition.
Keywords: Water treatment, cold plasma, UV, ozone, discharges

Tóm tắt

Công nghệ plasma đã và đang được nghiên cứu để ứng dụng trong lĩnh vực xử lý nước trong những năm gần đây. Công nghệ này có nhiều ưu điểm hơn so với các công nghệ truyền thống như clorine, ozone và UV. Plasma có hiệu quả cao trong khâu diệt hoặc bất hoạt vi khuẩn và vi sinh vật. Hơn nữa, plasma còn có khả năng ôxy hóa các hợp chất hữu cơ và vô cơ tồn tại trong nước. Bài báo này sẽ trình bày phương pháp tạo plasma lạnh từ phóng điện màn chắn trong không khí và các kết quả của việc xử lý nước bằng phương pháp này. Ngoài ra, bài báo cũng tóm tắt các phương pháp xử lý nước truyền thống và đề ra hướng nghiên cứu về plasma lạnh để xử lý nước trong điều kiện Việt Nam.
Từ khóa: Xử lý nước, plasma lạnh, UV, ozone, phóng điện
