Abstract Activated sludge biocenoses were compared on waste-water treatment plants in the city of Kazan, Russian Federation and the city of Teplice, Czech Republic. Based on Palia-Kovnatski index, Acanthamoeba in Kazan, Epistylis in Teplice, and Acanthamoeba and Centropyxis were dominant genera in both plants. The major subdominant generas identified were Arcella, Opercularia and Aspidisca. This indicates high nitrification ability, high water purification potential and matured activated sludge. Chemical composition of the waste-water was identified as the main factor determining the sludge biocenoses diversity. Higher sludge biodiversity (Shannon, Margalef, and Sorensen indexes) was found in Kazan corresponding to more concentrated inflow water.

Sulfuric acid residue is one kind of important secondary resource, its comprehensive utilization has drawn extensive attention. Based on analyzing the chemical composition of sulfuric acid residue, through comprehensive comparison of flotation, gravity separation, magnetized baking, magnetic separation and other joint technical processes, it is showed that the chemical-magnetic separation is reasonable by evaluating the applicable ability. Then introduced a case study on comprehensive utilization of sulfuric acid residue in Shikefeng chemical Co., LTD in Luzhou City, the duplex melting process combined advanced induction furnaces with smelting furnace was put forward. Finally, it's concluded that there are many advantages of the duplex melting process, it’s more suitable for the comprehensive utilization of sulfuric acid residue in small chemical enterprise.
