FulI scale experiment of the innovative integrated equipment for treating gas．field wastewater
Online published: 2010-10-01
A kind of innovative integrated equipment for treating gas-field wastewater has been developed． 1'lle equipment is composed of a series of units including coagulation，flotation，biological anaerobic hydrolysis and aerobic oxidation． e equipment has been used in agas-field wastewater treatment in Daqing for over two months． The ranges of COD and BOD in the influent during the full scale experiment are 2 3oo一51 050 ms／L and 1 290— 7379 mg／L．respectively． e removals of COD and BOD of the equipment achieve 96．68％ an d 99．77％ efluent COD an d BOD ran ge are 49-372 ms／L and 1．6—12．8 m Moreover，the removals of ammonia-nitrogen，sulfide and suspended solid achieve 95％,99．6％ and 84．97％,respectively．
Key words： gas-field wastewater; wastewater treatment; integrated equipment
