摘要： A method for predicting operation effectiveness of a decentralized sewage treatment facility by using a support vector machine, comprising: simultaneously collecting an influent conductivity and an effluent conductivity, and recording operation effectiveness of the decentralized sewage treatment facility; training a training set by using the support vector machine, with the influent conductivity and effluent conductivity as input and the operation effectiveness of decentralized sewage treatment facilities as output, so as to construct a prediction model for the operation effectiveness of decentralized sewage treatment facilities; and collecting the influent conductivity and effluent conductivity of the treatment facilities to be predicted, and inputting them into the prediction model to obtain a predictive result. The method is not only highly accurate, but fast and inexpensive.
