The study on start_up for UASB and treatment of wastewater containing RDX
This paper is intended to study the start up for UASB reactor that is seeded by cattle manure and to treat wastewater containing RDX.The results show that cattle manure can be used as seed material of UASB;effluent treated by the system containing UASB is achieved national standard of wastewater discharge;effect of treatment of RDX is good(the average removal rate reaches 88%) during anaerobic treatment.
Rainfed agriculture accounts for 92.8 m ha or 65% of total cultivated area which contributes about 44% of total food grain production and it supports 40% human and 60% livestock population. Rain water harvesting (RWH) can be done by two methods, in-situ and ex-situ. Among in situ mulching, broad bed and furrow (BBF), zay system and contour cultivation are prominent one. Cover crop and crop residue significantly reduces run off and soil loss under field conditions. In ex-situ watershed, check dams, microcatchments, farm ponds and microirrigation are promising one for soil and water management.
