This paper studies the use of bipolar-particles-electrodes in the decolorization of dyeing effluents. Treatment of highly colored solutions of various soluble dyes (such as direct, reactive, cationic or acid dyes) and also samples of dyeing effluents gave rise to an almost colorless transparent liquid, with removal of CODcr and BOD5 being as high as over 80%. The method is characterized by its high efficiency, low energy consumption and long performance life. A discussion of the underlying principle is given.

In recent years, the 1000MW ultra-supercritical unit has developed rapidly for its high efficiency and low energy consumption in china. In order to further reduce the energy consumption, the energy consumption distribution of a typical ultra-supercritical unit is analyzed in detail, which can make contribution for the energy conservation of units. Based on the theory of unit energy consumption and according to the thermodynamic calculation of a 1000MW ultra super critical generating unit under the design condition and off-design loads, this paper reveals the distribution of energy consumption rules of the whole unit, including every subsystem. The results indicate that when the load deviates from the design load, the total energy consumption of system will increase.

AbstractWith the development of industrialization, the emission of volatile organic compounds (VOCs) to atmosphere causes serious environmental problems and the treatment of VOCs needs to consume a lot of energy. Moreover, indoor VOCs are seriously harmful to human health. Thus, there is an urgent requirement for the development of indoor VOCs treatment technologies. Catalytic degradation of VOCs, as a low energy consumption, high efficiency, and easy to achieve manner, has been widely studied in related fields. As a kind of transition metal catalyst, manganese-based catalysts have attracted a lot of attention in the catalytic degradation of VOCs because of their unique advantages including high efficiency, low cost, and excellent stability. This paper reviews the state-of-the-art progress of manganese-based catalysts for VOCs catalytic degradation. We introduce the thermocatalytic, photocatalytic and photo-thermocatalytic degradation of VOCs on manganese-based catalysts in this paper. The optimization of manganese-based catalysts by means of structural design, decorating modification and defect engineering is discussed. Graphical Abstract
