The invention discloses a soft measurement method of nitrate nitrogen in drained water in anaerobic and denitrification type methane production process. The method is characterized in that genetic algorithm is utilized for optimizing BP neural network to construct genetic neural network, namely, the weight and the thread of the BP neural network are optimized through the genetic algorithm; the performances of the BP neural network optimized by the genetic algorithm are superior to those of general BP neural network. With the adoption of the method, the accuracy and the operation speed of a soft measurement model can be further improved; the nitrate nitrogen in drained water in the anaerobic and denitrification type methane production process can be quickly and accurately predicted. Therefore, the real-time quality monitoring level of nitrate nitrogen in drained water of a system for treating wastewater produced by anaerobic and denitrification type methane production can be improved; the problems such as that
