Introduced hereby are the deodorizing methods and their mechanism in common sewage treatment today, with specific analysis of the BENTAX and ECOLO methods and the technique for biological filter tank.

The use of odor removal technology with activated oxygen was finally determined in consideration of limited occupancy area and after the comparison of schemes.

This article introduces a kind of sulfur dioxide segradation device based on ozone technology,including the framework, the working principle and operational control, some related parameter requirements of usage and its application in solving the problem that the Sulfur Dioxide left in aquatic products or other food products.

This paper introduces the sensors that are used in the products with ozone technology and expounds the principle of the temperature sensors,light sensors and infra-red far-controlling technology which are usually used in the products with ozone technology.

The research progress of ozone technology was reviewed on decolorization of wastewater,minimization of excess sludge and reduction of endocrine disrupting chemicals(EDCs).

The component of odour and understanding about it was detailed in this paper, with the emphasison deodorization technique and its development trend and the related test methods.
