摘要: Abstract The upflow anaerobic sludge blanket (UASB) process is reported to be a sustainable technology for domestic wastewaters treatment in developing countries and small communities. However, the inability of UASB meet desired disposal standards has given enough impetus subsequent post treatment. In order upgrade based sewage plants (STPs) achieve effluent quality or reuse, various technological options are available broadly differentiated as primary post-treatment removal organic inorganic compounds suspended matter; secondary hardly degradable soluble matter, colloidal nutrients; polishing systems removals pathogens. Hence, this paper discusses different reactor treating sewage. Additionally, comparative review, an economic evaluation some emerging was conducted on extensive review integrated combination, i.e. UASB-different aerobic systems, concept natural biological mineralization route recognized advanced all practical aspects make it environmental protection, resource preservation recovering maximum resources.
