Abstract

At present, the production process of the leather industry is gradually developing towards being green and pollution-free. Therefore, an ecological evaluation of the leather industry is particularly important. In this paper, an ecological model of leather industry was established by using a BP (Back Propagation) neural network, and the appropriate indicators such as wastewater, COD, BOD, SS, Cr, S2- were selected for evaluation. The evaluation method improves the quality of evaluation of the ecological leather industry, and provides a reference for the evaluation of the ecological chemistry industry, which is conductive to the better realisation of the green development of the leather industry.
