摘要：

针对大庆地区气井采出水的水质特征,研制开发出一种新型的处理设备,该设备由混凝破乳、气浮分离、厌氧生物水解和好氧生物氧化多个处理单元组成。利用该设备对大庆油田某气井站进行了2个多月的现场处理试验研究。在进水COD质量浓度2300～51050mg/L、BOD质量浓度1290～7379mg/L,时该装置COD和BOD的平均去除率分别达到96.68%和99.77%,出水COD质量为49～372mg/L,BOD质量浓度为1.6～12.8mg/L。该装置对氨氮、硫化物和SS平均去除率也分别达到95%、99.6%和84.97%。

Abstract:

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
