Development of measures to reduce the negative impact of sewage sludge from pulp and paper production

Abstract

The article analyzed the technogenic load of a pulp and paper mill as a source of waste generation. Based on the analysis, the waste groups of the pulp and paper industry with the excess of education standards were identified, and among these groups suitable for recycling and reuse. Among such wastes, osprey was isolated - waste from the processing of sewage sludge from the pulp and paper industry. The stages of the technological process of manufacturing pulp and paper products from recycled materials were also considered. An analysis of scientific and technical information was carried out, within the framework of which the features of the main technical solutions in the field of processing and disposal of osprey were investigated. An electro-osmotic plant was developed, the essence of which is to achieve maximum energy efficiency in the process of dewatering sewage sludge from the pulp and paper industry. According to the results of the experiments, a correlation assessment was made of the parameters of electroosmotic dehydration: reduction of the residual mass of the osprey and current strength on the plant plates during electroosmosis, from which it follows that the values of the cross-correlation coefficient are significantly affected by the electric field strength of the electroosmosis.
