Application of CYYF Whole Process Deodorization in Jizhuangzi Wastewater Treatment Plant

Abstract

A new biological deodorization technology which is used in Tianjin Jizhuangzi Sewage Plant was introduced in this paper. The geographical position of Jizhuangzi Wastewater Treatment Plant is special. The plant has been surrounded by the living area. The problem of odor to people has been serious until a new deodorization technology is used. It is a source deodorization technology used special filler through vaccination, induction and catalytic to removed the malodorous sources. A special microbial incubator is used to culture and proliferate effective deodorant microorganisms on activated sludge sewage in the biological pool of the plant and then the sludge containing deodorant microbial reflowed to the wastewater inlet. The malodorous substances in the water are removed through adsorption, cohesion, biotransformation degradation and so on by the deodorant microbial. The case indicates that this technology is effective in practice and good for popularization. And this technology with simple process showed significant effect compared with other deodorant technologies and was more secure and convenient to build and run with low cost.
