There are many ways to produce hydrogen. The most widely currently used methods of conversion and steam-electrolysis. Recently, much attention is paid to the photochemical process for producing hydrogen. In the future, the development of fusion reactors could be economically feasible hydrogen production thermo chemical decomposition of water. Hydrogen can be obtained by steam-coal conversion.
In this case you must separate the hydrogen from carbon dioxide and other conversion products. This problem cannot be considered as approved. One of the main methods of producing hydrogen in the near future is considered electrolysis at nuclear power plants. In addition to hydrogen and oxygen are released, which can also be used in industry and everyday life. In addition to electrolytic considered thermo chemical and photochemical methods for producing hydrogen. Thermo chemical method to obtain might be particularly promising in the development of fusion power plants. However, to apply this method to solve the problem of separating hydrogen and oxygen. Of great interest is the photochemical decomposition of water by way of using biological catalysts.
Protection of water basin.
Characteristics of wastewater. Water used for industrial or domestic purposes and which has received pollution, which changed its properties and to be treated or removed from this object or place, is called waste. The composition of waste water is exceptionally varied and depends on the type of production. In the wastewater may contain toxic substances such as cyanide, arsenic, selenium, mercury, lead and cadmium. The greatest amount of impurities is water chemical, mining, pulp and paper, oil refining and coal processing industries. These waters contain acids or alkalis, salts, respectively, refined oil products and coal processing, etc. To produce 1 kilowatt hour of electricity requires about 200-400 liters of water. To use CHP capacity of 1,000 MW to 1.2-1.6 km 3 of water per year, and the same power plant - 3 km3 year ". At the stations, large capacity a day dumped 1,000 tons or more of water contaminated with impurities.
Depending on the purpose of the initial water effluent can be divided into the following types:
1. reaction of water in which water is the reaction product;
2. source of water contained in raw materials or reagents, such as water of coal;
3. aqueous solutions resulting from reactions in aqueous media;
4. rinse waters after washing of raw materials, the reaction products and equipment;
