Summary: | The invention relates to a hybrid intelligent algorithm-based soft measurement method for effluent ammonia nitrogen of an anaerobic system, and aims to solve the problems of long measurement time lag,high price, difficult maintenance and the like in measurement of effluent ammonia nitrogen concentration in the anaerobic wastewater treatment system. According to the method, real-time detection ofthe effluent ammonia nitrogen in anaerobic wastewater treatment is successfully realized through a hybrid intelligent algorithm of principal component analysis and a least squares support vector machine based on biochemical characteristics of the anaerobic wastewater treatment. An experiment proves that a correlation coefficient between an effluent ammonia nitrogen prediction value in the soft measurement method and an actual measurement value is 0.9970, so that a soft measurement model can quickly and accurately predict the effluent ammonia nitrogen concentration; the quality monitoring levelof the effluent ammonia ni |
