Digital process regulations for environmentally safe diversion and treatment of waste water from wood processing plants

Abstract

The environmental hazard from formaldehyde-containing wastewater from wood processing enterprises was analyzed, including their extremely negative impact on active sludge from biological treatment facilities. The disadvantages of using technological regulations at production plants were assessed, which made it possible to substantiate the main tasks in improving the efficiency of technical regulation of water use. Schemes of digital technological regulations for wastewater diversion and treatment have been substantiated and developed, which has a structural similarity with digital twins in terms of the implementation of operational monitoring. The use of fuzzy neural networks, which provide the generation of production rules, in this case, which are the basis of intellectual knowledge bases, has been proposed and tested for modeling preliminary chemical cleaning. A structural diagram of the corresponding digital technological regulation was substantiated and created, consisting of two methodological and algorithmic blocks: monitoring of processes that have static boundary values of technological parameters and a single intellectual knowledge base of processes that determine environmental safety according to the parameters "Concentration of formaldehyde," "Chemical oxygen consumption" and "pH." An algorithm for the implementation and regular operation of such a software and hardware complex has been developed. The main advantages of the proposed digital technological regulations for the disposal and treatment of formaldehyde containing wastewater from wood processing enterprises have been identified.
