Development of methods for wastewater treatment of galvanic production from copper ions (II) by filtration sediment
The presented material is devoted to sewage treatment of the galvanic enterprises. Despite all measures applied in the field pollutants continue to come to water objects. The existing methods of sewage treatment are difficult, insufficiently effective, expensive therefore a relevant task is search of new highly effective and cheap methods of sewage treatment. Also one of important problems of industrial centers remains a problem of placement and recycling of production and consumption, being one of the most dangerous types of the technogenic loadings which are negatively influencing state of environment today. Therefore in this work the possibility of use of technogenic waste as reagents for sewage treatment is considered. As a method of sewage treatment of galvanic productions sedimentation of ions of heavy metals by means of waste of beet sugar production is offered. It is considered influences of mass of the defekat and also hashing time for efficiency of sewage treatment of galvanic productions from ions of copper (II). The thermal way of activation of the defekat is offered at various temperatures. It is raised the question of economic efficiency from use of the defekat for sewage treatment therefore it is revealed that use of waste of beet sugar production allows to increase efficiency of cleaning in comparison with use of traditional extinguished lime. Hardware registration of sewage treatment from ions of heavy metals is offered. Possible ways of utilization of a deposit of water purification are considered and the scheme of production of pottery about use as additive of the waste of beet sugar production received after extraction of ions of copper (II) is submitted. At assessment of influence of the received pottery on the environment by method of biological testing it is revealed that the received material aren't toxic.
