Abstract:

Aiming at the issue of water bloom control in Xiangxi state，algae density is selected as a measurement index and measured by electronic tongue technology.Based on the theory of Fourier series and Logistic model，the optimal water bloom pollution treatment model in Xiangxi region is established，and six commonly used methods of pollution treatment are compared by regret criterion.The results show that it is more economical and effective to handle water bloom pollution with the microorganism flocculating agent enhanced coagulation method from March to May.Finally，the measures to prevent and control water bloom combined with the local characteristics of Xiangxi state are presented.

Key words: Fourier series, logistic theory, regret criterion, electronic tongue technology
