The invention provides a papermaking industry water pollution abatement process regulating and controlling method, and relates to papermaking industry water pollution abatement processes. An evaluation index system of the papermaking industry water pollution abatement processes is determined; states of the various papermaking industry water pollution abatement processes to be evaluated are described; an ideal process state of the optimal index of the mth process is described; differences between the corresponding indexes in a matrix R0N and a matrix Rmn are described; the index weight is determined, the degrees of importance of various process evaluation indexes are described, an Euclid approach degree composite fuzzy matter-element matrix is built, and the degree of closeness of the processes to be evaluated and ideal processes is described; the evaluated processes are sorted, and a scheme is output to regulate the sewage treatment processes so that papermaking industry sewage can accord with industry regulations. According to the method, specific technique of papermaking industry water pollution abatement can be combined, the optimal technique is given, poor technique is updated and improved, the direction is provided for an improvement to existing papermaking industry water pollution abatement technique, and meanwhile support is provided for development of the papermaking industry water pollution abatement technique.
