Abstract:
At present time chemical reagent modes are everywhere used for purification of the soiled waters of technological productions (sewage). The cleared waters thus in addition become soiled the elements participating in chemical reactions and materials of coagulants. As alternative to these methods consider technologies of direct and return osmosis if it is a question of small volumes of sewage.
In this work results of the pilot studies executed in the last decade on approbation of new methods of processing of soiled fresh waters (the reagentless methods) are analysed. To the reagentless methods refer ultra-violet, microwave (superhigh-frequency), laser and laser and magnetic processing of water. The main experimental results of basic researches executed in this direction are stated. Their efficiency, the technological devices applied to these purposes and preliminary treatment methods is analysed.
Judgments on the gear of allocation of pollution are stated at laser radiation. Advantages of the reagentless methods of sewage treatment are shown, examples of practical application are given, possible ways for speedup of terms of industrial use of devices on the basis of ultra-violet, microwave, laser and laser and magnetic radiations and fields are stated because in Russia the most various sources of radiation and magnetic systems, and also new devices for water preliminary treatment are produced in lots.
