Abstract
A line for post-treatment of wastewater from the production of protective coatings (PPC) and printed circuit boards (PCB) introduced at the base enterprise JSC "BEMZ" was developed and studied. The operation of the post-treatment line has confirmed its performance, low power consumption, low water consumption for own needs. It is shown that the scheme of stepwise reuse of wastewater makes it possible to vary the degree of post-treatment depending on the production requirements for the quality of process water and the composition of the wastewater entering the treatment. In this case, the degree of return of water in. production will be 85-90%.
Subject of study. Wastewater from the production of protective coatings and printed circuit boards
Materials and research methods. In the work, studies of the elements of the wastewater treatment line PPС and PPP at the treatment facilities of the base enterprise were carried out and, on the basis of them, a pilot production line for wastewater treatment was developed and implemented. When conducting research on a pilot plant, the obtained conclusions were verified, which were used to develop technologies for the post-treatment of various types of wastewater from the PPС and PPP, as well as the improvement of process equipment and sludge disposal in the production of building materials.
Results. The introduction of a resource-saving technology for post-treatment of wastewater from the production of protective coatings and printed circuit boards made it possible to reduce the amount of process equipment to a minimum and reduce the need for purchased reagents by more than an order of magnitude, as well as more than halve the need for production space for its placement.
Conclusions: It has been established that the choice of a scheme for post-treatment of water for the production of protective coatings and printed circuit boards depends mainly on the quality of the initial composition of wastewater and the requirements for treated water. At the same time, when choosing the most appropriate options for post-treatment of wastewater PZP and PPP for a particular consumer. it is necessary to separate the flows of the least polluted wastewater and return them after treatment to the needs of technical water supply.
Studies of the elements of the line for post-treatment of wastewater PPС and PPP at treatment facilities were carried out
JSC "BEMZ" and on the basis of them developed and implemented a pilot production line for wastewater treatment. The obtained research results were transferred to design institutes for the creation of circulating water supply systems for subordinate enterprises
